Embodiment 1

[0027] see Figure 1 to Figure 9 , the support 2 of the cervical vertebra traction resetter of the present invention is made up of two parallel iron rods, and one of these two iron rods is hinged on the hinge seat 7 that is arranged on the human body support plate 1 (see Figure 5 and Figure 9 ), wherein the distance between the two iron rods near one end of the hinge seat 7 is relatively large, and the distance between the two iron rods at the other end is relatively small; the human body support plate 1 is a plank. see figure 1 and figure 2 , the bracket 2 is located at the end of the two iron rods with a smaller distance and is provided with a slider 3, and the slider 3 is provided with two sliding sleeves 3-3 that are enclosed in the two iron rods, and the slider 3 faces One end of the bracket 2 hinged with the human body support plate 1 is connected with the traction bow 4 through the rope 5, and the other end is connected with the traction mechanism. Wherein, the t...

Embodiment 2

[0031] see Figure 12 and Figure 13 , in this example, the traction mechanism is a ratchet mechanism, the ratchet mechanism includes a base plate 16 and a ratchet wheel 17 arranged on the base plate 16, wherein the base plate 16 is fixed on the connecting block 9, and the ratchet wheel 17 is provided with a pawl below 20 , the ratchet 20 is provided with a torsion spring 22 , and the elastic force exerted by the torsion spring 22 on the ratchet 20 makes the ratchet 20 always abut against the ratchet 17 . The rotating shaft of ratchet 17 is provided with driving lever 18, and this driving lever 18 is provided with the plectrum 19 that buttresses on the corner of the gear tooth of ratchet 17, and plectrum 19 is provided with torsion spring 22, and this torsion spring 22 dials The elastic force exerted by the piece 19 makes the plectrum 19 always abut against the ratchet 17; the ratchet 17 is provided with a wire wheel 23 coaxial with the ratchet 17. A spring tension gauge 10 ...

Embodiment 3

[0035] see Figure 14 , in this example, the traction mechanism is a threaded transmission mechanism, which consists of a nut 3-4 arranged on the slider 3 close to one end of the traction mechanism and a screw 8 matching the nut 3-4, wherein the One end of the above-mentioned screw rod 8 is passed through the sliding bearing hole in the connection block 9 .

[0036] Embodiments other than the above in this embodiment are the same as in Embodiment 1.

[0037] Taking Embodiment 1 as an example below, the working process of the cervical traction reducer of the present invention will be further described in conjunction with the accompanying drawings:

[0038] see figure 1 and figure 2 , before performing the traction operation, first set the traction distance: rotate the adjustment screw 11 at the bottom of the support plate 6, thereby adjusting the position of the end of the support plate 6 in the guide groove 3-1, so that the support block 3-2 is close to the traction bow T...

Abstract

The invention discloses a cervical traction reducing apparatus, which has a body supporting plate (1) and a traction device arranged on the body supporting plate (1), wherein the traction device consists of a support (2) of which one end is hinged on the body supporting plate (1), a sliding block (3) arranged on the support (2), a traction bow (4) and a traction mechanism, and the traction bow (4) and the traction mechanism are both connected with one end of the sliding block (3) respectively; and the traction bow (4) is connected with one end, which is toward the hinged point of the support (2) and the body supporting plate (1), of the sliding block (3). The cervical traction reducing apparatus is characterized in that: the body supporting plate (1) corresponding to the sliding block (3)is provided with a supporting plate (6) is vertical to a vertical plane of the sliding direction of the sliding block (3); the sliding block (3) corresponding to the end of the supporting plate (6) is provided with a guide slot (3-1); and a through groove passing through the supporting plate (6) is arranged on the end, which is toward the traction bow (4), of the guide slot (3-1), and one end of the traction mechanism has a sinking tank.

Description

technical field [0001] The invention relates to an orthopedic appliance for non-surgical treatment of bones or joints, in particular to a cervical vertebra tractor. Background technique [0002] Cervical dislocation is a cervical spine injury in which the cervical vertebrae slip and the facet joints lock up due to trauma. At present, there are two clinical treatment methods for cervical dislocation: non-surgical treatment and surgical treatment. Among them, the non-surgical treatment usually refers to the skull traction reduction method. This method fixes the traction bow on the skull and uses weights to apply force to the traction bow. , so that the dislocated articular surface is loosened to achieve the purpose of reduction. During the traction reset process, set the initial weight of the weight (for example, the initial weight of the weight in the Cotler method used by most foreign countries is 10 pounds, about 2.5kg), and then increase a certain weight at regular interv...
