Description

Cane

The present invention can be used for both right-handed and left-handed canes with only a single cane in various canes including multi-point canes, and a single cane can be used with either left or right hand without discomfort. A new cane that can be used, can greatly contribute to the improvement of walking ability by replacing the cane tip rubber according to the degree of walking ability of the user, and can prevent the cane tip rubber from coming off. It is to provide.

A cane as a walking aid for elderly people and persons with disabilities who have difficulty walking is required to have both stability to maintain body balance, stability to support weight, and propulsive force to support smooth walking.
The conventional 4-point cane has a wide support base and is stable, but the base of the cane has a plate shape supported by four metal pipes and rubber, so the cane tip is like a foot. It did not bend and could not step back, and the rotational force did not have the function of supporting propulsion during walking.
As a result, the cane had to be moved up and down, and the walking posture had to be extended along the handrail.
By the way, a conventional cane is often formed on the assumption that it has a grip shape for the right hand and is used by a user who uses the right hand, and a user who holds such a cane with the left hand often holds it. When used, the grip did not fit the left hand, which caused inconvenience and danger such as injury or injury to the left hand during use.
On the contrary, even if it is formed to have a grip shape for left hand use and is configured on the assumption that it is used by a user who uses left hand, the same problem has occurred for a user who uses right hand.
In addition, the shape of the tip of the cane has been of particular concern for conventional canes, but the cane is the third "foot", and in order to firmly support the weight on the ground, the left and right grips are distinguished, and the hands are separated. It is important to be able to press the ground firmly with your palm.
However, for example, in the case of a cane having a grip shape for the right hand, it is assumed that it is used by a user who can only use it with a right-handed person or the right hand (in the case of a cane having a grip shape for the right hand, the opposite is true). ), If the right hand is injured or paralyzed and the right hand cannot be used, you will have to use a cane with a grip shape for the right hand with the left hand, but since the grip shape does not fit, It became more difficult to use, and the situation was caused in which the palm of the hand could not press the ground firmly and the weight could not be firmly supported on the ground. Therefore, the ground support was made to be able to be gripped with both hands at the expense of the important feature of distinguishing the left and right grips.
In addition, it is necessary for cane dealers to always prepare canes for both right-handed and left-handed use, which causes problems such as an increase in inventory space and an increase in labor for transporting products.
Furthermore, focusing on the details of the cane, in the case of a conventional cane, for example, a conventional four-point cane, the rubber tip constituting the four-point cane and the bottom surface of the support substrate at the tip of the cane were connected by a manual screw connection. Insufficient connection strength of the tip rubber with the bottom surface of the support substrate has caused inconveniences such as wear of the tip and part of the end rubber and detachment of the tip rubber.
As a technique related to the present invention, Patent Document 1 includes a grounding portion, a rod-shaped portion, and a grip portion, has a male screw pedestal on the upper part of the grounding portion, and inserts a connecting pipe penetrating the male screw pedestal into the rod-shaped portion. By tightening the male screw pedestal and the hand-cranked cylindrical female screw, the grounding part and the rod-shaped part are fixed so that when the user's physical condition does not match, the grounding part and the rod-shaped part that match the physical condition can be easily attached. A multi-point support cane that can be rearranged is disclosed.
Further, in Patent Document 2, the cane's ridge and handle are elastic so that when it is struck, it has a function as a cane that supports it at multiple points, and when it is lifted, it has a function as a general single-point cane. It is connected freely up and down via the body, and the tip has a double structure so that the auxiliary leg moves downward and touches the road surface when a load exceeding a predetermined value is applied, while maintaining ease of movement. A cane configured to be stable in the support of the user is disclosed.
However, including the above-mentioned techniques of Patent Document 1 and Patent Document 2, it is possible to use both right-handed and left-handed canes with only one cane, and to contribute to improvement of walking ability by replacing the rubber cane tip. Furthermore, there is currently no cane that takes into consideration the reduction of wear of a part of the cane tip rubber due to the increase in the connecting strength of the cane tip rubber and the prevention of the tip rubber from coming off.

Registered Utility Model No. 3195836 JP-A-2006-110346

The present invention has been developed in view of the above-mentioned conventional circumstances, and can be used for both right-handed and left-handed use with only one cane, and how to use the cane or walking of the user of the cane. It can greatly contribute to the improvement of walking ability by replacing the cane tip rubber according to the degree of ability, and further, by connecting multiple cane tip rubbers, the overall strength is increased, and the friction of the cane tip is increased. It provides a new cane that is dispersed (reduction of wear biased to a part of the cane tip) and can prevent the cane tip rubber from coming off.
In detail, the shape of the tip of the cane is important for the user of the cane regardless of whether it is used with the right hand or the left hand, and at the same time, the grip is used to firmly support the weight by pushing the cane with the entire palm of the hand. The shape of the part is important.
That is, in general, the cane is usually held by the healthy side (non-affected side) opposite to the affected lower limb in order to widen the basal support surface, for example, the left leg is the affected side. In the case of, it is usually held with the right hand, and when both lower limbs are on the affected side, it is usually held with the hand on the leg side with mild symptoms, and in the same person, new disorders such as fractures and paralysis may be added over time. In some cases, the left and right hands holding the cane may be switched, and there is also the possibility that one cane may be shared and used within the family. In such a case, the grip shape is left and right (right hand). It is very convenient to support use (use, left hand use).
In this way, it is important to be able to use both the right hand and the left hand with only one cane, and to be able to use one cane with either the left or right hand without discomfort. The invention was developed from this point of view.
Furthermore, regardless of whether the grip shape is for the right hand or the left hand, even if the same person uses the cane, the hand holding the cane may change depending on various circumstances and conditions. In any case, the cane according to the present invention has the versatility that even the same user can handle left and right with one cane, and the range of use with one cane is expanded, which is convenient. It improves sex.

The cane of the present invention has a pole portion that can be adjusted in length, a grip for the right hand that can be attached and detached to the rear end of the pole portion, a grip for the left hand that can be attached and detached to the rear end of the pole portion, and the pole portion. A radial support bracket placed at the tip and a cane tip that can be attached to and detached from the support bracket with a tool, screwed in a radial arrangement, and have a plurality of configurations that abut each against the ground plane and have a hard and soft combination of hardness. The most important feature is to have rubber.

Multi-point cane (items subject to long-term care insurance rental)
Next, regarding the cane 1 according to the present embodiment, the following examples can be given as the relationship between the height of the user and the length (total length) of the cane 1.
Height (cm) 133 138 143 148 153 158 163 168 173 178
Length (cm) 65 67.5 70 72.5 75 77.5 80 82.5 85 87.5
Next, the functional features of the cane 1 according to this embodiment will be described in comparison with the conventional T-cane (single-point cane) and multi-point cane.
Since the cane 1 of the present embodiment is supported by the basal plane of the large cane tip region, it is highly stable in supporting the weight in the front, back, left and right, and assists in maintaining the body balance in the standing position.
Furthermore, in order for a total of six

cane tip rubbers

31A and 31B, for example, a substantially oblong hexagonal shape and the flexibility of the cane tip rubber to create a rotational movement back and forth that causes the cane to roll on the ground. It promotes the forward swing from the extension of the hip joint, and stably assists the weight transfer due to the dorsiflexion of the ankle joint. This has a function of assisting the propulsive force before walking, and walking can be improved.
Furthermore, since the arrangement of the six

cane tip rubbers

31A and 31B can be changed, the cane 1 can be replaced by changing the

cane tip rubbers

31A and 31B according to the walking condition and walking distance of the individual user. The landing is supported by the cushioning property of the relatively soft cane tip rubber 31B, the propulsive force to move forward is performed by the repulsive force of the relatively hard cane tip rubber 31A, and the left and right grips of the cane are exchanged. It becomes possible to secure the stability of firmly poking the ground with a cane while supporting the weight, and it is possible to easily realize custom-made to suit the user's condition.
Such a feature is an original function peculiar to the cane 1 of this embodiment, which has never existed in the past.
That is, the two unique functions of the cane 1 of this embodiment, that is, stability and propulsion, realize a walking improvement function that was impossible with the conventional T cane and the multi-point cane.
Comparing the conventional multi-point cane or assist multi-point cane with the cane 1 of the present embodiment, the conventional multi-point cane has a fixed cane tip assembled with rubber and sponge, and the length of the cane tip is also 10. It is about 2 cm. The cushioning property of the sponge causes the cane to rotate when it is swung back and forth, creating propulsive force.
Therefore, it can be said that the conventional multi-point cane is sufficient for elderly people who do not have much instability in the standing position and do not have much imbalance between the left and right bodies when walking.
In addition, when walking for a long time such as when going out, it can be said that the conventional multi-point cane is easier to use because the tip of the cane is small and light.
The cane 1 of this embodiment is a fixed type because a plurality of round suction cup-shaped

rubber cane tips

31A and 31B having a diameter of about 3.5 cm are screwed into a support metal fitting 21 formed in the shape of an ostrich's foot. The feature is that it can be attached and detached.
When the

cane tip rubbers

31A and 31B are worn out or partially worn, the user can easily replace the

cane tip rubbers

31A and 31B at any time.
Further, since the

cane tip rubbers

31A and 31B are firmly screwed to the support metal fitting 21 by the hexagon wrench 41, it is possible to prevent the

cane tip rubbers

31A and 31B from coming off from the support metal fitting 21.
Further, the arrangement of the

cane tip rubbers

31A and 31B having different hardness can be arbitrarily changed by changing the walking state.
Furthermore, originally, the place where the cane is pierced differs depending on the change in the walking state of the user, but according to the cane 1 of this embodiment, the cushioning property when piercing the cane and when pushing forward The arrangement of the 6 points of the

cane tip rubbers

31A and 31B, which have different hardnesses to distinguish the repulsive force of the cane, can be arbitrarily changed according to the state in which the user's cane is pierced. At the same time as having the effect of returning to nature, it also has the effect of suppressing pain in the elbow caused by poking the cane, and as a result, the fatigue caused by walking with the cane is reduced, and the pain can be reduced.
Therefore, the hardness of the

cane tip rubbers

31A and 31B can be selected and the arrangement can be changed according to the walking characteristics of the user, which is an epoch-making point that could not be achieved with the conventional T cane or the multi-point cane. It is a characteristic.
Moreover, the cane tip region of the cane 1 according to this embodiment has a wide basal surface with a front-back length of 12.8 cm and a left-right side of 10.7 cm, and six independent

cane tip rubbers

31A and 31B are omitted. Due to the oval shape, the cane tip area, such as the shape of a ostrich's foot, provides a grip that grips the ground, similar to kicking the ground so that the sole rotates outward and moving forward. Since the propulsive force is generated one by one from the back to the front along the rotational movement of the cane 1, the force that supports the smooth movement of the weight when the cane 1 is pierced is outstanding. ..
The conventional classification of canes is divided into multi-point canes and single-point canes, excluding so-called crutches and Lofstrand Crutch, and even for those who need rehabilitation, only the stability of weight support is emphasized and walking The function of propulsion support was sacrificed, and there was no choice but to use a four-point support multi-point cane supported by an inflexible four-point pipe.
Those who are trained in "side cane" or "walker" in rehabilitation will have stable physical balance and weight support required for the cane when shifting to walking training with the cane 1 of this embodiment. It has become possible to support both the two important aspects of human walking: sex and the propulsion force that stretches the hip joint, bends the ankle joint, and moves forward on both sides.
In addition, welfare equipment specialists and therapists such as many physiotherapists praised the completely different functions of the cane 1 as "a cane of a different dimension" and "an unprecedented cane". Has been evaluated.
In fact, as a walking improvement effect, the measurement result shows that the number of steps is reduced and the walking speed is increased even when walking at 10 m. In other words, it has the effect of improving the ability to walk faster with the star.
Since the cane 1 of this embodiment belongs to the multi-point cane as a classification, it is subject to the welfare equipment loan of the long-term care insurance.
As described above, the cane 1 of the present embodiment exerts an extremely excellent effect from the viewpoint of improvement of walking function and stability of weight balance support.
In addition, the flexibility of a total of 6

cane tip rubbers

31A and 31B realizes the same propulsive force as stepping back, and there is also a custom-made property that the

cane tip rubbers

31A and 31B can be replaced according to the improvement state of walking. There is also an advantage that the effect of walking improvement can be verified by this.
Next, the walking analysis result of the user using the cane 1 of this embodiment will be described.
The effect of the cane 1 of this embodiment on walking will be described as a result of comparison with walking alone and conventional T-cane walking.
(How to analyze walking)
User F (male, 82 years old, old-fashioned cerebral infarction: right hemiplegia, Br. Stage: upper limb VI, hand VI, lower limb VI) "walking alone", "walking with T cane", "cane of this example" I asked them to "walk" and photographed the situation. The still image is "Perry Gait Analysis Original 2nd Edition Normal Walking and Abnormal Walking" (Jacquelin Perry, Translated by Isao Takeda and Mitsunori Yumioka, Medical and Dental Publishing Co., Ltd., March 2012 / Original: "GAIT ANALYSIS-Normal" The analysis was performed according to the "Phase of Gait" described in "and Pathological Function Second Edition", Jacquelin Perry, Slack Inc., 2010).
(result)
The results are summarized in the following [Table 1], which is the phenomenon observed in the analysis of various items for "self-walking", "T-cane walking", and "cane walking in this embodiment".

The meanings of ◯, Δ, and × shown in Table 1 are as follows. ◯: Phenomenon was observed, Δ: Phenomenon was slightly observed, ×: Phenomenon was not observed.
According to these, improvement in walking was observed in both "conventional T-cane walking" and "cane walking in this example", but the cane walking in this example was found to be more improved than the T-cane walking. Was done.
(Discussion)
In other words, in "Dokuho", the upper body was tilted to the right in the middle stage of stance, but this was caused by moving the center of gravity closer to the right lower limb in order to compensate for the weakness of the gluteus medius muscle of the right (affected side) lower limb. Conceivable.
In addition, in "conventional T-cane walking" and "cane walking of this embodiment", by attaching these canes, the weight support on the right (affected side) lower limb can be shared by the cane itself, so that the upper body can lean to the right. It is considered to have been improved.
In addition, in "Dokuho", dorsiflexion of the foot and knee extension were not observed at the end of the swing leg, but it is considered that this was not observed due to insufficient right foot dorsiflexion and knee extension muscle strength due to hemiplegia. ..
In addition, by attaching these canes for both "conventional T-cane walking" and "cane walking in this embodiment", the weight support on the right (affected side) lower limb can be shared by the cane itself, so that the lower limb muscle weakness can be compensated. It is probable that the right hip joint also became easier to flex, and the stride length became wider than that of "single walking" during the initial contact period of the right lower limb.
At this time, the cane walking of this embodiment can support the weight more stably and surely than the "T cane walking" due to the influence of the wide cane tip area and the shape of the cane tip rubber portion, so that the cane walking can support the weight more stably and surely than the T cane walking. It is considered that the muscle weakness could be compensated for, and as a result, it became possible to touch the ground ahead of walking with the T-cane.
In addition, in the cane walking of this example, the cane can be firmly pierced from the initial contact period of the right (affected side) lower limb to the anterior swing phase, and the left (healthy side) lower limb can be further struck by the force of the arm. It is considered that the cane can be strongly pushed out to the rear of the body side from the anterior swing period to the early stage of the swing leg, which promotes the swing of the left (healthy side) lower limb and increases the stride length.
As described above, in the cane of this example, the left (healthy side) lower limb can be greatly extended forward during the initial contact period, and as a result, the right (affected side) lower limb hip joint is passively extended. As a result, a toe locker was also found on the foot.
At that time, the right (affected side) lower limb gastrocnemius muscle is stretched, and the force accumulated there causes plantar flexion in the anterior swing phase and kicks the ground, and the reaction causes foot dorsiflexion, which causes heel rocker in the load response phase. Is also considered to have been recognized. It is considered that the knee extension tendency was also recognized for the same reason.
(Summary)
Gait improvement was observed in both the T-cane walking and the cane walking in this example.
Heel rocker and toe rocker were found on the right (affected side) lower limb when walking with a cane in this example.
As for the stride length, the stride length increased in the order of walking alone, walking with a T-cane, and walking with a cane in this embodiment.
In addition, walking with a cane in this example showed a tendency for dorsiflexion and knee extension of the right (affected side) lower limb at the end of the swing leg, compared with walking with a T cane.
In the cane walking of this embodiment, the weight can be firmly supported due to the large area of the cane tip and the material and shape of the cane tip rubber, and as a result, a more stable and smooth gait than the T cane walking is recognized. It was.
Next, an academic explanation and a case study regarding the cane of this example will be described.
(Academic consideration of the cane of this example)
Regarding EBM (Evidence Based Making), in order to increase the propulsive force during walking, the structure allows the arm to swing according to the swing phase, and it assists the extension of the hip joint (hip joint strategy). It is considered to be useful.
That is, in the two-dimensional motion analysis, when the other canes are compared with the canes of the present embodiment, the data of the extension angle of the hip joint and the floor reaction force are collected and verified, and the results are obtained superiorly, the above effect is obtained. It is believed that there is.
(Consideration on the hardness of the cane tip rubber)
Early stance: A low hardness is preferable as a shock absorbing function when the heel touches the ground.
Late stance: Needs assistance with the kicking function at the toes to generate forward propulsion.
⇒Since the floor reaction force is applied, the material that sinks is not suitable. Inevitably harder.
Summary: If the rear rubber has a lower hardness than the front rubber, it is considered that a slight difference in hardness does not affect walking so much.
(Specific case)
(Case 1)
Diagnosis name: Lumbar compression fracture Dementia (short-term memory disorder / disorientation)
Since there is a decrease in trunk muscle strength when standing, it is easy to take a forward leaning posture when walking, and the cane is poking in front of the body. In order to generate propulsive force for walking, the trunk is tilted forward and a cane is thrust in front of the trunk to walk.
(Rehabilitation intervention to correct gait)
He was walking with a T-cane as shown in the left column of Fig. 13, but his trunk leaned forward significantly.
As shown in the right column of FIG. 13, after changing to the cane of this embodiment, the forward tilt of the trunk decreased, probably because the smooth movement of the center of gravity of the basal plane in the cane tip rubber worked. Improvements in trunk control (posture control function in the front-back direction) during walking have made it possible to touch the cane to the side of the body. In the posture, the forward leaning of the trunk during walking decreased, and the number of falls decreased.
Since the hardness of the cane tip rubber can be changed, a cane tip rubber with a higher hardness was used on the left side, and a cane tip rubber with a softer hardness was used on the right side.
(Current walking ability: Independence of walking at home-watching)
Walking on the floor in the wide day service became possible by watching over.
(Awareness)
There was no change in the objective posture or numbers, but there was a decrease in low back pain, etc., and at one point I was almost bedridden, but after that I was able to confirm that I was living vigorously at home. ..
(Case 2)
Diagnosis: Spinocerebellar degeneration Stage III
(Independence of home life correction using welfare equipment)
Onset of median nerve palsy due to carpal tunnel syndrome, appearance of limb imbalance. Unsteady movement of the center of gravity in BOS (Blowout Score: a value for evaluating the blood flow in blood vessels during one heartbeat), both during walking Knee tremor appears, and the knee joint tends to become unsteady due to poor coordination.
Grip: Backscratcher's cane (due to median nerve paralysis, deformity of monkey hand, confrontational movement / grip is difficult: grip strength of about 5 kg on both sides)
(Uses conventional T cane)
As shown in the left column of FIG. 14, a state in which lateral swaying on the left and right is strongly observed on the side where the center of gravity is moved during the entire walking cycle. Postural control under hip / knee strategy is liable to be impaired due to ataxia. Compensatory movements for stabilizing the center of gravity are also seen due to the effects of ataxia.
When using a T-cane, the maximum stride length tends to decrease from the initial stage of stance to the middle stage of stance because the ataxia symptom of the knee joint tends to increase lateral sway.
With the T-cane, it is difficult to extend the hip joint and kick the ankle joint in the latter half of the stance in order to take a step while controlling the lateral sway by yourself (while not shaking sideways) after the middle stage of the stance, and widen the stride. With a wide base, it is easy to walk by swinging the trunk from side to side.
(Using the cane of this example)
As shown in the right column of FIG. 14, a characteristic of walking with a cane of this embodiment is a decrease in lateral sway.
That is, lateral ataxia due to left and right ataxia decreased.
In addition, the propulsive force was improved due to the stability in the left-right direction. The trunk is agitated forward and tends to lean forward.
FIG. 15 shows the gait states (end of stance to initial ground contact) of each of the six types of the user in the cane (using the left hand) walking, the walking without the cane, and the conventional walking with the T cane according to this embodiment.
There are a total of six gait states: a stance end, b initial contact / load response period, c stance middle stage, d stance end, e pre-swing period, and f initial contact.
Table 1 above shows the evaluation results of the heel rocker, ankle rocker, forefoot rocker, and tow rocker related to the above-mentioned b initial ground contact / load response period, c middle stance stage, d stance end stage, and e-pre-swing period. ..
FIG. 16 shows the presence or absence of dorsiflexion of the foot (early swing leg) of the user when the cane according to the present embodiment is used, when the cane is not used, and when the conventional T cane is used.
The evaluation results regarding the presence or absence of dorsiflexion of the foot of the user in this case are shown in Table 1 above.
FIG. 17 shows the presence / absence (initial ground contact) of knee extension in the case where the cane according to the present embodiment is used, the case without the cane, and the case where the conventional T cane is used.
The evaluation results regarding the presence or absence of knee extension of the user in this case are shown in Table 1 above.
FIG. 18 shows the state of the stride length of the user when the cane according to the present embodiment is used, when the cane is not used, and when the conventional T cane is used.
The evaluation results regarding the presence or absence of knee extension of the user in this case are shown in Table 1 above.
FIG. 19 shows a state in which the user's upper body is tilted to the right (mid-standing) when the cane according to the present embodiment is used, when the cane is not used, and when a conventional T-cane is used.
The evaluation results regarding the state of the user's upper body leaning to the right in this case are shown in Table 1 above.

The cane of the present invention can be widely used for rehabilitation of patients in nursing homes, hospitals, clinics, etc., and for assisting walking of ordinary people with weak legs.
