Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Please refer to fig. 1, fig. 1 is a schematic structural view of a cervical vertebra tractor provided by the present invention.
The embodiment of the utility model provides a cervical vertebra tractor, this cervical vertebra tractor includes: the device comprises a bracket 10, an energy storage extension spring 13, a driving device 30 and a jaw pillow belt 20; wherein,
the support 10 comprises two fixedly connected supporting legs 11, a traction wheel 15 is arranged at the joint of the two supporting legs 11, a shoulder rest 12 is arranged at the bottom end of each supporting leg 11, an energy storage extension spring 13 is arranged in each supporting leg 11, one end of each energy storage extension spring 13 is fixed at the bottom end of each supporting leg 11, and the other end of each energy storage extension spring is connected with a movable pulley 14;
the jaw pillow belt 20 comprises a flexible belt 22 and a traction rope 21 connected to two ends of the flexible belt 22; the two traction ropes 21 respectively pass through the movable pulleys 14 in the two support legs 11 and then are fixed on the traction wheel 15;
the driving device 30 is fixedly arranged at the joint of the two supporting legs 11 and is used for driving the traction wheel 15 to rotate.
In the above described embodiment, the support frame 10 of the present retractor comprises two fixedly connected support legs 11, which support legs 11 form a portal-shaped retractor frame. The traction frame and shoulder rest 12 are used to provide a supporting or reaction force for traction. Energy storage extension springs 13 are arranged in support legs 11 on two sides of the traction frame, and each energy storage extension spring 13 with the maximum tension of 100N is arranged in each energy storage extension spring. The bottom of the supporting leg 11 is provided with a shoulder support 12, the shoulder support 12 is saddle-shaped and is rotationally connected with the supporting leg 11, can rotate left and right to automatically adapt to different shoulder shapes, and is provided with a sliding groove for properly adjusting the width. The top of the traction frame is provided with a driving device 30.
The traction wheel 15 drives the traction rope 21 to be drawn to the jaw pillow belt 20 through the movable pulley 14 which is connected with the energy storage extension springs 13 at the two sides, and the energy storage extension springs 13 are also pulled apart and store the traction force while the traction is applied. The lower ends of energy storage extension springs 13 in the support legs 11 at the two sides of the traction frame are fixed, and the upper ends are free and connected with movable pulleys 14. The main functions of the device are to accumulate traction, buffer the rising speed of the traction and quantitatively control the magnitude of the traction. The two-sided stored energy extension spring 13 can store and maintain a maximum of 100N of traction force. The cervical traction is a static traction because the cervical vertebrae cannot be elongated, and the stress of the cervical vertebrae is increased along with the increase of the tension of the energy storage extension spring 13.
The jaw occipital strap 20 is in a standard style, and two sides of the jaw occipital strap are tightly attached to the lower jaw to increase the contact area, reduce the pressure and prevent the jaw from being uncomfortable. Those retractors that do not use standard style occipital straps do not understand their principles.
The tractor adopts the energy storage extension spring 13, and has the following important functions:
the energy storage function of the energy storage extension spring 13 enables the traction force to be kept relatively stable all the time after meeting the requirement, and the traction force cannot be lost or increased due to the movement of the neck, the shoulder and the upper limbs.
As the stored energy tension spring 13 is continuously extended during the traction process, a very important working stroke is produced. This operating stroke makes it possible to use a motor drive, since the motor also needs to be operated. Another important function of the working stroke is to make possible a quantification of the tractive effort, the magnitude of which directly reflects the magnitude of the tractive effort. Note that this work stroke is different from the essence of the so-called "traction stroke".
Since the magnitude of the traction force is proportional to the degree of extension of the stored energy extension spring 13, the magnitude of the traction force can be indicated by the degree of extension of the stored energy extension spring 13. The traction force scale at the longitudinal opening of the right upright post is based on data obtained by experiments carried out by hanging standard weights on the jaw pillow belt 20.
In summary, the following steps: the tractor is really a tractor with a working stroke.
Preferably, the driving device 30 includes a driving motor and a speed reducer connected to the driving motor, and the traction wheel 15 is sleeved on an output shaft of the speed reducer. Due to the buffering effect of the reducer, the energy storage extension spring 13 and the movable pulley 14, the traction force increasing process is very slow, and a patient has sufficient time to experience the feeling of the traction force and make proper adjustment.
Preferably, the traction wheel 15 is sleeved on the output shaft and can rotate relative to the output shaft, a release pull rod 19 for locking the traction wheel 15 is rotatably arranged on the output shaft, when the release pull rod 19 rotates to a first set position, the traction wheel 15 is locked with the output shaft, and when the release rod rotates to a second set position, the traction wheel 15 can rotate relative to the output shaft; the chain traction device further comprises a traction hand chain 31, wherein the traction hand chain 31 is sleeved on the traction wheel 15 and can drive the traction wheel 15 to rotate. As a final safety, the emergency release lever 19 in front of the top of the traction frame is pulled open, rotated and then pulled out of the two gears if necessary, immediately disconnecting the traction wheel 15 from the reducer and the manual sprocket. The brake of the reducer and the manual chain wheel is lost, and the traction wheel 15 is immediately and completely released. The multiple insurance ensures the absolute safety of the tractor used at the vital parts of the human body.
Preferably, the traction block sliding pointer 16 on the movable pulley 14 on the at least one supporting leg 11, and the traction force scale arranged on the supporting leg 11 and used for matching with the traction sliding pointer 16, wherein the traction force scale is provided with a scale. The front of the energy storage extension spring 13 bin of the right supporting leg 11 is provided with a longitudinal opening and a traction force scale, and a traction block sliding pointer 16 connected with the free end of the energy storage extension spring 13 can visually display the current traction force. The buffering of the movable pulley 14 and the energy storage extension spring 13 greatly increases the working stroke during traction, and the traction force can be accurately adjusted. The stored energy extension spring 13 is used to store energy to provide stable and controllable traction.
Preferably, the device further comprises a control device 40, wherein the control device 40 is in signal connection with the driving device 30 and is used for controlling the driving device 30 to drive the traction wheel 15 to rotate. Specifically, the traction drive system is controlled by a wired switch control 40. The traction switch of the control device 40 adopts a inching design, and the control device stops when being released, so that accidents can be avoided. The release switch is divided into a inching switch and a continuous switch, and the continuous release switch can be used when necessary to completely release traction.
Preferably, the cervical vertebra tractor is provided with a traction force safety control block 17 and a buzzer 18; the control device 40 is respectively in signal connection with the traction force safety control block 17 and the buzzer 18, and when the traction sliding pointer 16 touches the traction force safety control block 17, the control device 40 controls the buzzer 18 to give an alarm and prevents the driving device 30 from driving the traction wheel 15 to rotate along the direction of tensioning the jaw pillow belt 20. A maximum traction force safety control block 17 is arranged above a traction sliding pointer 16 in front of the right supporting leg 11, the maximum traction force can be set according to parameters such as the traction body position, the weight, the size of a skull of a patient and the like, after the maximum traction force is set, when the traction sliding pointer 16 reaches the traction force safety control block 17, a buzzer 18 prompts, a built-in mechanism automatically cuts off a traction line, traction is stopped, and a release line of motor reverse rotation is kept smooth continuously. When the traction slide pointer 16 leaves the traction force safety control block 17, the traction circuit is restored to normal again.
As can be seen from the above description, the tractor inherits the advantages of the traditional traction mode, and the traction force is stable and controllable. Any position can be selected when in use, including lying, sitting and the like. But more convenient is: the fixed movable pulley 14 is not needed, and the rope can move freely after being pulled up no matter what body position is selected, and no heavy load is needed. It should be noted that when the sitting position traction is selected, it is not possible to change to lie flat without adjusting the traction. Because the weight generated by the weight of the skull needs to be overcome when the traction is carried out in the sitting position, the traction force needs to be increased by a force equivalent to the weight of the skull compared with that when the traction is carried out in a horizontal position, so that the traction force is changed into the horizontal position, and the traction force is not changed due to the action of the energy storage extension spring 13, but the traction force applied to the cervical vertebra is increased by a force equivalent to the weight of the skull.
For example, the weight of the skull of a person is about 4kg, the sitting position is used for traction, and the maximum traction force is set to be 6 kg. At this time, the actual traction force applied to the cervical vertebrae is 2 kg. The patient is allowed to lie down and the cervical vertebrae will be subjected to 6kg of traction if the frictional resistance is neglected. While the system always displays a traction value of 6 kg.
This is consistent with conventional traction, and different traction forces must be selected for different body positions. This is an indication that the traction force is stable. The tractor varieties which claim that the body position can be randomly changed after traction without influencing traction actually prove that the tractor does not have the capability of continuously stabilizing traction; and, at the same time, is also unscientific.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
