Description

  The present invention comprises a projecting member that is slidable in the axial direction and an affected part projecting member that is detachably attached to the distal end of the projecting member, and presses the affected part projecting member against a treatment point, When a shocking axial force is applied to the rear end portion of the projecting member, the affected site projecting member hits the treatment point, and the skeletal displacement is corrected. is there.

  A plurality of bones connected by joints, that is, the skeleton, shifts due to various factors. There may be a sudden shift due to an impact from the outside due to an accident or the like, and a shift may occur gradually due to chronically taking the same posture due to lifestyle and occupational needs. Such a skeletal shift causes various diseases. In particular, it is widely known that cervical vertebral deviation causes stiff shoulders, dizziness, headaches, etc., and there are reports that it causes internal organ malfunctions, decreased immunity, decreased visual acuity, and allergic diseases.

  As a method for correcting such a skeletal shift, there is a manual method that is performed by a practitioner such as a chiropractor, as is conventionally known. For example, when correcting a cervical vertebral deviation, the patient is laid on the examination table in a lying state. Then, a slightly projecting bone at the base of the little finger of the operator's hand is brought into contact with a specific portion of the bone of the cervical vertebrae where the deviation occurs, that is, the operation point, and in a predetermined direction at once. Push in with force. Then, the cervical vertebral deviation is corrected. According to this method, since the bone at the base of the little finger is small, the treatment point can be accurately pushed with a pin point. Further, as another method using the hand, there is a method in which the surgeon's thumb belly is quickly abutted toward the treatment point from a separated position.

  However, there is a problem that such a conventionally known manual method requires a considerable degree of skill. For example, with respect to the former method, the protruding bone at the base of the little finger is relatively dull, and it is difficult for a practitioner who is less skilled to contact the treatment point accurately. Furthermore, since it is difficult to adjust the force, there is a risk of pushing the bone to be corrected more strongly than necessary. On the other hand, the latter method not only has the same disadvantage as the former method that it is difficult to adjust the force, but if the skill level is low, there is a risk that the direction will shift and the part other than the treatment point may be struck. .

U.S. Pat. No. 4,116,235

  Patent Literature 1 proposes a body trimming instrument that can accurately strike the treatment point with the adjusted force regardless of the level of skill of the practitioner. FIG. 5 shows a body trimming instrument 50 described in Patent Document 1. As shown in FIGS. 5A and 5C, the body trimming instrument 50 is generally a tubular body 55 and a rod-like member that is inserted in front of the tubular body 55 so as to be slidable in the axial direction. The projecting member 52, the main body 53 having a larger diameter than the tubular body 55 and slidably covered in the axial direction on the tubular body 55, the cap body 54 fixedly attached to the rear end portion of the tubular body 55, the cap body 54 includes a pressing bar 61 attached to the rear end of the finger 54, a finger grip 62 fixed to the main body 53, and the like. A part of the rod-like projecting member 52 is inserted in the vicinity of the distal end portion of the tubular body 55, the other part is exposed, and an adjuster 56 for adjusting the abutting force to the treatment point is attached to the exposed part. Yes. A head 52a having an enlarged diameter is provided at the front end portion thereof, and the affected part projecting member 51 is attached to the head 52a. The affected part projecting member 51 is made of an elastic material such as rubber, and as shown in FIG. 5A, a circular treatment surface 51a directly abutted on a treatment point, and a diameter larger than that. The bottom surface 51b and the peripheral surface 51c whose diameter is expanded from the treatment surface 51a toward the bottom surface 51b. As shown in FIG. 5C, a recess 51d having a predetermined depth is opened on the bottom surface 51b. The affected part projecting member 51 is attached so as to cover the head 52a using the recess 51d. An impact rod 57 is inserted into the tubular body 55. The impact rod 57 is urged forward, that is, in the direction of the protruding member 52 by a spring 58 inserted in the rear portion of the tubular body 55. Thus, the front end portion 57 a of the impact rod 57 is in contact with the rear end portion 52 b of the protruding member 52.

  As shown in FIG. 5A, such a body trimming instrument 50 is held by holding the holding bar 61 against the base 70 of the thumb of the palm and hooking the index finger 71 and the middle finger 72 on the finger grip 62. And the treatment surface 51a of the affected part protrusion member 51 is pressed against the treatment point. Next, the finger grip 52 is driven in the direction of the holding bar 61 so as to hold the palm. Then, the main body 53 slides in the arrow A direction with respect to the tubular body 55. At this time, the impact rod 57 is also integrated with the main body 53 and slides in the direction of arrow A against the spring 58 by a locking mechanism not shown in the drawing. By this sliding, the front end portion 57 a of the impact bar 57 is separated from the rear end portion 52 b of the protruding member 52. Further, when the finger grip 52 is driven and the pressing bar 61 and the finger grip 62 are at a predetermined distance B, the locking mechanism is released. Then, the impact rod 57 is urged by the spring 58 and pushed forward, and the tip end portion 57a of the impact rod 57 strikes the rear end portion 52b of the projecting member 52 in an impact manner. The projecting member 52 is momentarily pushed forward, the treatment surface 51a of the affected part projecting member 51 strikes the treatment point, and the displacement of the skeleton is corrected.

  According to the trimming instrument 50 described in Patent Document 1, the affected part projecting member 51 is pressed against the treatment point in advance, so that the abutted portion is less likely to deviate from the treatment point. Further, since the abutting force can be adjusted by the adjuster 56, it is possible to perform the treatment safely with the adjusted abutting force. Therefore, even a practitioner with a low skill level can easily perform the treatment. However, there are problems or drawbacks to be improved. In particular, the affected part projecting member 51 is recognized to be improved. In other words, the affected part projecting member 51 of the orthopedic instrument 50 described in Patent Document 1 is not particularly considered for the shape, and therefore, particularly for a part where a plurality of bones are closely arranged, such as the cervical spine. There is a problem that it is difficult to hit only the treatment point, or when the part covered with tissue such as relatively thick muscle or fat is the treatment point, the force to hit is difficult to act on the bone itself is there. Hereinafter, the reason will be described with reference to FIG.

  The human cervical vertebra is composed of seven cervical vertebrae, like the first cervical vertebra, the second cervical vertebra, and so on, from the side closest to the skull, and each cervical vertebra is relatively thin and flat, such as cartilage It is densely stacked with FIG. 4 is a view schematically showing a cross section of the neck in the second cervical vertebra portion of such cervical vertebrae. As shown in this figure, the second cervical vertebra K has a substantially inverted triangle with the protrusion T1 located on the back SN side and the left and right protrusions T2 and T3 as vertices, respectively. Covered with tissue N such as muscle and fat. Examples of the deviation generated in the second cervical vertebra K include a linear deviation Z1 and a rotational deviation Z2 with respect to other adjacent cervical vertebrae such as the first cervical vertebra and the third cervical vertebra. When correcting such a cervical vertebral shift using the orthopedic instrument 50 described in Patent Document 1, for example, to correct a linear shift Z1, tissue N such as muscle or fat in the vicinity of the protrusion T1 is used. The affected part projecting member 51 is pushed into the vicinity of the projection T1 in such a manner as to be pushed away, and then thrust in the direction indicated by the arrow S1. Then, the protrusion T1 is pushed in the direction opposite to the arrow Z1, and the deviation is corrected. By the way, the projection T1 of the second cervical vertebra is adjacent to the projection of the first cervical vertebra and the projection of the third cervical vertebra, and the projection T1 of the second cervical vertebra is lower than the projection of the third cervical vertebra and is deep from the skin. . When such a protrusion T1 is abutted, in the affected part protrusion member 51 having a circular treatment surface 51a described in Patent Document 1, there is a possibility that other adjacent cervical vertebrae, particularly the protrusions of the third cervical vertebrae, also protrude at the same time. . Furthermore, since the treatment surface 51a is wide and has no effect of pushing away the tissue N, there is a problem that the projection T1 that is still covered with the relatively thick tissue N must be projected, and the force to grip the projection T1 is weak. Further, when the protrusion T1 covered with skin, fat or the like is struck, the treatment surface 51a slides sideways with respect to the protrusion T1, and as a result, the treatment point may be shifted.

  On the other hand, in order to correct the deviation Z2 in the rotational direction, the projection T2 is struck from the lower left rear so that the projection T2 serves as a treatment point, or the projection T2 is abutted in the direction indicated by the arrow S2. Then, the shift Z2 in the rotation direction is corrected. By the way, since the projection T2 is covered with a tissue N such as a relatively thick muscle, the affected part projecting member 51 of the body trimming instrument 50 described in Patent Document 1 is pushed so as to push the tissue N from the lower left rear of the left projection T2. Even if the treatment surface 51a is pushed in, the shape of the treatment surface 51a is wide and circular, so that it is difficult to sufficiently push the tissue N, and the affected part projecting member 51 cannot be hooked on the projection T2. Further, even if the affected part projecting member 51 is abutted in such a state, it receives the resistance of the thick tissue N, and it is difficult to sufficiently apply the abutting force to the protrusion T2.

  An object of the present invention is to provide an affected part projecting member for a body fitting instrument that solves the above-described problems or problems. Specifically, even in a region where bones are closely arranged, it is possible to accurately Only the treatment point can be struck, the treatment point can be firmly gripped, and even if the treatment point is covered with relatively thick muscles or fat, the abutment force is sufficiently applied to the bone to be corrected An object of the present invention is to provide an affected part projecting member for a body trimming instrument that can be acted upon.

  In the present invention, in order to achieve the above object, the affected part projecting member which is detachably or selectively attached to the projecting member is made of an elastic material such as rubber or synthetic resin. The affected part projecting member is formed with a treatment surface that strikes a treatment point and an escape surface that allows tissues such as muscles and skin to escape. These treatment surfaces and relief surfaces are formed by cutting off the tip portion of the main body having a substantially cylindrical shape into a tapered shape at a predetermined angle. Since the treatment surface and the relief surface are formed as a result of the taper cut off, the treatment surface is formed in a small area with a narrowed shape, and the relief surface is formed on the side of the treatment surface.

  That is, in order to achieve the above-mentioned object, the invention according to claim 1 is a projecting member that is slidable in the axial direction, and an affected part projecting member that is detachably attached to the tip of the projecting member. When the affected part projecting member is pressed against the treatment point and a shocking axial force is applied to the rear end of the projecting member, the affected part projecting member strikes the treatment point and the skeletal displacement is corrected. In the trimming instrument, the affected part projecting member is formed in a substantially cylindrical shape from an elastic material such as rubber or synthetic resin, and its tip is cut into a tapered shape over a predetermined length, thereby forming a tip on the tip. A treatment surface with a small area that squeezes into the treatment point is formed, and a relief surface that allows tissue such as muscle and skin to escape is formed on the side of the treatment surface. According to a second aspect of the present invention, in the orthopedic appliance according to the first aspect, the affected part projecting member is cut off in a tapered shape over a predetermined length at a predetermined angle with respect to the shaft from both sides, thereby substantially reducing the distal end portion. A treatment surface having a rectangular shape is formed, and relief surfaces are formed on both sides of the treatment surface. The invention according to claim 3 is the orthopedic device according to claim 1, wherein the affected part projecting member is formed from both sides. A taper is cut off over a predetermined length at a predetermined angle with respect to the shaft, and the central portion of the tip is cut out in an arc shape, thereby forming two treatment surfaces at the tip. A relief surface is formed on a side portion of each treatment surface, and the invention according to claim 4 is the orthopedic device according to claim 1, wherein the affected part projecting member is tapered from the periphery at a predetermined angle over a predetermined length. Cut into a shape It is thereby with treatment surface having a substantially circular shape is formed at its distal end, relief surface around the treatment surface is formed.

  As described above, according to the present invention, since the treatment surface is composed of a small area that is narrowed from the periphery, only the treatment point can be accurately struck, and at this time, the side of the treatment surface is escaped. Because the surface is formed, you can grip the treatment point firmly and poke. That is, according to the present invention, since the affected part projecting member has a treatment surface and a relief surface, even if the treatment point is covered with relatively thick muscles, fats, etc., the treatment point is firmly gripped and treated. An effect peculiar to the present invention that a thrust force can be applied to only the point accurately and sufficiently can be obtained. Further, according to the present invention, since the affected part projecting member is detachably attached to the projecting member, the affected part projecting member having a desired shape and size is selectively attached so that a desired treatment suitable for the purpose can be performed. The effect that can be obtained is also obtained.
