Description

  The present invention relates to a cervical traction device and a cervical traction device for fixing and guiding the head and neck used for cervical spine injury, traumatic cervical syndrome, and the like.

  A conventional cervical traction device 20 (see, for example, Patent Document 1) used for traction of the cervical spine is combined with a traction device 21, a chair 22, and the like to constitute a cervical traction device 23 as shown in FIG.

  In this conventional cervical traction device 20, the anterior support portion is a mandibular chin portion, and the posterior support portion is a support portion for the occipital nodule. There is a mandibular reflex, and it is difficult to obtain a resting state in the muscles around the cervical spine due to the pressure during traction.

  In particular, subjects who complain of pain in the muscles around the head and neck due to malocclusion often have problems with the temporomandibular joint. It was an incentive to make it worse.

In addition, the cervical traction direction is considered to be the most effective traction from the upper front, and the peripheral muscles need to be rested to correct joint contracture and alleviate nerve root compression caused by cervical traction. However, the chair 22 of the conventional cervical traction device does not have a backrest portion, and it is difficult to specify the cervical traction direction and does not have a function of resting the peripheral muscles.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory view of the entire cervical traction device 3 according to an embodiment of the present invention, and FIG. 2 is an explanatory view of the cervical traction device 2 in use. The cervical vertebra traction device 3 includes a cervical traction device 2, a traction device 4, a support column 5, a guide roller 6, a wire 7, a hook 8, and a chair 9.

  The cervical traction device 2 is a cervical traction device 2 having a belt 1 attached to the head of a subject in a sitting posture or standing at an appropriate angle, and the belt 1 is formed on both sides from the vicinity of the rear surface of the subject's cervical vertebra. The head is sandwiched between the front and upper parts so as to be worn.

  The cervical traction device 2 includes a belt 1 and a length adjusting member 10. The belt 1 is a flat belt made of an appropriate material. The length adjusting member 10 is a metal ring.

  A front upper part from both heads of the subject to which the belt 1 hits is a front support part, and a vicinity of the cervical vertebra rear surface part is a rear support part. The portion that hits the front support portion of the belt 1 is provided with a resilient member (not shown) used as a mattress material on its inside, so that the height of the front of the auricle is increased. The cervical traction is ensured and comfortable for the subject without crushing the pinna.

  The cervical traction device 2 has a function of adjusting the length of the belt 1 by moving the length adjusting member 10 that has passed the belts 1 on both sides up and down, and freely adjusts to the size of the head of the subject. Can be adapted to The surface of the belt 1 has a rough surface structure having irregularities, and the length adjusting member 10 can be fixed.

The pulling direction of the cervical vertebra by the cervical vertebra pulling device 2 is inclined backward by an arbitrary angle (θ ₁ ) with respect to the vertical direction (Y). The front hook 8 and the cervical traction orthosis 2 from the guide roller 6 provided at the distal end portion of the lateral arm installed on the column 5 of the traction machine 4 are arranged in a straight line along the traction direction.

  It is desirable that the cervical traction device 2 has an appropriate flexibility so that the belt 1 passes through the portion of the subject and the traction is performed without causing discomfort to the subject. . Further, if the width of the belt 1 is too narrow, the resting state of the head and neck muscles cannot be obtained due to discomfort due to concentration of traction force, and if it is too wide, the degree of freedom of the extension action of the upper cervical vertebra is hindered. It is desirable to have an appropriate width so as not to cause a problem.

  When an appropriate force is applied to the back of the occipital bone from a predetermined direction by the belt 1 of the cervical traction device 2, the upper cervical vertebra connection portion extends and the skull tends to bend forward, but the belt 1 surrounded by the front of the head The cervical traction device 2 is prevented from being detached from the zygomatic arch and the frontal bone, since the action of bending the skull backward is added.

  The material of the cervical traction device 2 can be leather or cloth, but can be modified in various ways without departing from the gist of the present invention, for example, by having appropriate softness and width such as synthetic resin. is there. In addition, a metal ring is used as the length adjusting member 10 for tightening the head of the cervical traction device 2, but it is possible to obtain the same effect by, for example, a hook, and the present invention is not limited to this configuration. The head and neck position of the cervical traction device 2 is described in detail as a reference position, but some errors can be obtained in the same way, and the present invention is not limited to this.

  Further, as shown in FIG. 3, the length adjusting member 10 of the cervical traction device 2 may have a shape in which a ring is arranged at both ends of a bar having an appropriate length. In this case, the interval between the belts 1 that sandwich the head from both sides is widened, and the uncomfortable feeling to the auricle can be removed.

  The traction machine 4 is driven by a motor and pulls the cervical traction orthosis 2 through the hook 8 by winding the wire 7. The angle at which the cervical traction device 2 is pulled can be appropriately set by changing the position of the guide roller 6.

The chair 9 is composed of a backrest part 11, a headrest part 12, an armrest part 13, and a seat part 14, and from a predetermined angle (θ ₁ ) of the cervical traction device 2 given to the vertical direction (Y). By applying a large angle (θ ₂ ) to the backrest 11 in advance and tilting it backward, the cervical traction device 2 and the subject's head are defined by the cervical traction device 2, and the cervical traction device 2 and the back of the subject's head A friction force is generated between the lower parts of the nodules.

  If the supporting part of the cervical traction device 2 is obtained only at the lower part of the occipital nodule, sufficient fixation cannot be obtained, and the cervical traction device 2 may be detached, but the chair 9 should be made of a flexible mat material. By adopting it, it is possible to prevent the cervical traction device 2 from being detached above the skull.

In this embodiment, the backrest portion 11 is fixed in a state where it is inclined backward to a predetermined angle (θ ₂ ) in consideration of cost, but the angle can be adjusted by the reclining means so that the reclining angle is adjusted. It is also possible to make the cervical traction treatment more comfortable by adjusting the cervical traction direction by the corresponding optimum angle.

  The headrest portion 12 is provided above the backrest portion 11 via the coupling mechanism 15. The coupling mechanism 15 includes an upper support bar 16, a lower support bar 17, an upper hinge 18 and a lower hinge 19, and the upper hinge 18 is disposed between the back side of the headrest part 12 and the upper end part of the upper support bar 16. The hinge 19 is disposed between the lower end portion of the upper support bar 16 and the upper end portion of the lower support bar 17 so that the degree of vertical extension of the headrest portion 12 can be changed and adjusted. Furthermore, the lower hinge 19 is provided with a rotation adjustment function, and the headrest portion 12 is configured to be able to deal with subjects of all symptoms and physiques.

  On the other hand, the upper hinge 18 of the headrest portion 12 has a function of freely tilting backward and changing and adjusting its bending angle, so that the muscles around the head and neck are always in a resting state without hindering the extending action of the cervical spine. It is configured so that it can be secured.

  The armrest portion 13 makes it possible to avoid emergency discomfort during traction of the cervical spine and maintain a left-right equilibrium state with respect to the traction direction. Further, by providing the armrest portion 13 with a rotary opening / closing function, it is possible to facilitate seating and unseating.

  Further, in the above description, two hinges are attached as means for freely tilting the headrest portion 12 at the upper hinge 18 so that a resting state of the muscles around the head and neck can be obtained. The same effect can be obtained by attaching two hinges, and the structure of the headrest portion 12 is not limited to this.

  It should be noted that the chair 9 can be variously substituted within a range not departing from the gist of the present invention, such as a treatment chair in a dental clinic, a barber / beauty chair in a beauty salon, and the like.

  In addition, the cervical vertebral traction device 3 can be used as an auxiliary treatment for occlusion treatment in a mandibular deviation patient who has cervical spondylosis. That is, it is possible to correct a strong cervical vertebral curvature by performing cervical traction therapy in addition to occlusion treatment to a subject who seems to have a curved cervical vertebrae due to mandibular deviation. As described above, the conventional cervical traction device has a problem in compressing the most important temporomandibular joint in occlusion treatment. However, according to the cervical traction device 3 of the present invention, there is no such problem. Moreover, since the chair 9 can be used as a treatment chair in a dental clinic, it can be used for both occlusion treatment and cervical traction therapy, and can be used particularly effectively in a dental clinic.

  Furthermore, it is also possible to provide a space in which the traction machine 4, the cervical vertebra traction device 2 and the like can be built under the seat portion 14 of the chair 9 so that the space can be made compact when not in use.

  Next, the state of the subject when using the cervical traction device 3 will be described.

  As shown in FIGS. 1 and 2, when the belt 1 of the cervical traction device 2 is attached to the subject's head, the head and neck placement position is near the rear posterior surface of the upper cervical vertebra, and the belt 1 The belt 1 that traverses and extends to the left and right of the head passes through the lower part of the bilateral occipital papilla, passes through the lower part of both auricles, and exits forward and upward so as to sandwich the bilateral zygomatic arch. The belt 1 extending to the left and right passes through the length adjusting member 10 toward one place and is connected to the hook 8 at the tip of the wire 7.

FIGS. 4A to 4D are schematic diagrams showing changes in head position due to a difference in angle (θ ₁ ) with respect to the vertical direction (Y) of the cervical vertebra pulling direction by the cervical vertebra pulling device 2.

  FIG. 4 (a) shows a resting state in which no traction force is applied to the cervical traction device 2, and a resting state of the muscles around the head and neck of the subject can be ensured by adjusting the headrest portion 12 up and down and back and forth. .

  FIG. 4 (b) shows a case where the head is pulled from the front rather than the ideal pulling direction, the head position is bent backward, and the subject's upper cervical vertebra is uncomfortable and is inappropriate.

  FIG. 4 (c) shows an ideal case where it is pulled in the same direction as the long axis of the cervical vertebra.

  FIG. 4 (d) shows a case where the head is pulled backward from the ideal pulling direction, and the head position bends forward, causing discomfort to the auricle, which is inappropriate.

The predetermined angle (θ ₂ ) given in advance to the backrest portion 11 of the chair 9 is substantially the same as the cervical long axis below the axial vertebra, and the angle (θ ₁ ) in the cervical traction direction is adjusted. This makes it possible to pull the intervertebral disc without causing discomfort in the extension of the cervical spine joint.

  FIGS. 5A to 5C are schematic diagrams showing changes in the head position caused by the difference in the length of the cervical traction device 2.

  FIG. 5 (a) shows a case where the cervical traction device 2 is shorter than the ideal cervical traction device 2, and the head position is bent backward, causing discomfort on the rear surface of the upper cervical vertebra, which is inappropriate.

  FIG. 5B shows the case where the cervical vertebra pulling device 2 has an ideal length, and the head position does not rotate, and the cervical vertebra pulling device 2 is pulled in substantially the same direction as the cervical long axis.

  FIG. 5 (c) shows that the cervical traction device 2 is longer than the ideal cervical traction device 2, and the head position is bent forward, causing discomfort to the auricle and inappropriate.

  The cervical vertebral traction device 2 adjusts the length of the subject to adjust the head position of the subject and enables desired comfortable traction.

  FIGS. 6A to 6C are schematic diagrams showing the influence on the auricle and the upper cervical vertebra due to the difference in the height of the headrest portion 12 of the chair 9.

  FIG. 6A shows a case where the headrest portion 12 is too high, and discomfort caused by the cervical traction device 2 is generated in the auricle, which is inappropriate.

  FIG. 6B shows the case where the headrest portion 12 has an ideal height.

  FIG. 6 (c) shows that when the headrest portion 12 is too low, a cervical vertebral overhanging condition may occur, which may exacerbate the nerve root symptom on the posterior surface of the cervical spine.

  That is, the second cervical vertebra and the following vertebrae are in the same direction regardless of the height of the headrest portion 12, but the degree of flexion of the occipital atlanto-vertebral joint varies depending on the height of the headrest portion 12.

  The cervical traction device 2 according to the present invention is mainly constituted by a single belt 1 and a length adjusting member 10, and the length adjusting member 10 is moved up and down to arbitrarily set the traction direction and length of the cervical traction device 2. By setting it to, the pressure to the front and rear support parts can be distributed to deal with all symptoms and the size of the head of the subject, so that the operability is good and can be used simply.

  This cervical traction device 2 is configured as described above, and does not require the supporting part of the cervical traction device 2 in the lower jaw, but mainly in the lower edge of the occipital bone nodule, so there is little discomfort, and the head and neck It is easy to obtain a resting state of surrounding muscles. Therefore, the effect by cervical traction is increased. Therefore, it is desirable to apply a weaker load than when using a conventional cervical traction orthosis. If the traction force is too strong or the pressure distribution to the front and rear support parts is wrong, the front and rear support parts are painful. In particular, great care must be taken because compression on the pinna is easily painful.

  Further, the posterior support portion of the cervical traction device 2 is also a portion corresponding to the muscle group directly under the occipital bone, and moderate compression and relaxation produce a massage effect.

In addition, the cervical traction device 3 has the subject's head and neck muscles in a resting state by a predetermined angle (θ ₂ ) inclined backward of the backrest portion 11 of the chair 9, and the headrest portion 12 causes the subject's head to rest. By placing the part in a desired position, the head and neck muscles are in a relaxed state at any time during towing and at rest. Further, it is more reliable that the practitioner specifies the traction direction of the cervical spine by the difference between the predetermined angle (θ ₁ ) of the cervical traction device 2 and the predetermined angle (θ ₂ ) given to the backrest 11. Enables effective cervical traction.

  FIG. 8 shows a further improvement of the cervical traction device 2 of the present invention. In this cervical vertebra pulling device 2, as shown in FIG. 9, substantially trapezoidal rings 24 having different lengths on the left and right sides are respectively interposed between the belts 1 on both sides of the subject.

  In the ring 24, the left and right sides 24a and 24b are parallel, and the upper side 24c and the lower side 24d are inclined and tapered due to the difference in length between the sides 24a and 24b. The ring 24 is attached to the belt 1 on each side of the subject so that the upper side 24c is lowered rearward and the lower side 24d is raised rearward. The upper and lower ends of the middle of the belt 1 to which the ring 24 is attached are folded back so that the insertion portions 25 of the upper side 24c and the lower side 24d of the ring 24 are formed inside, respectively, by sewing, bonding, metal fittings 26, etc. It is fixed. The upper side 24c and the lower side 24d of the ring 24 are rotatable at the insertion portion 25, respectively.

  As shown in FIGS. 1 to 3, the belts 1 extending left and right from the vicinity of the posterior surface of the upper cervical vertebra sandwich the head, pass forward and upward, and are connected to the hook 8. When viewed, the taper shape narrows upward, but by providing the ring 24 in the middle of the belt 1 on both sides of the subject, the belt 1 has the front and inner sides of the subject's head (the belts 1 on both sides of the head). The force of heading toward the direction in which the interval is narrowed works to increase the function of preventing the belt 1 from being detached from the head of the subject.

  Further, the cervical traction device 2 is provided with a occipital support band portion 27 as shown in FIG. The occipital support band 27 is a combination of left and right temporal bone support portions 27a, 27b and a central occipital bone support portion 27c, and each end of the belt 1 on both sides of the subject has left and right temporal bone support portions 27a. , 27b are rotatably attached by a metal fitting 28.

  The temporal bone support portions 27a and 27b are wider than the belt 1, the occipital bone support portion 27c is about the same width as the belt 1, and the areas of the temporal bone support portions 27a and 27b are large and fit well to the subject. Therefore, the stability and usability of the cervical traction device 2 are more excellent.

  In addition, the cervical vertebral traction device 2 can be configured such that either the ring 24 or the occipital support band portion 27 is not provided. The cervical traction device 2 can be freely combined with the length adjusting member 10 and other components as appropriate.
