Embodiment 1

[0043] Such as figure 1 The shown device is the first embodiment provided by the present invention, including a reset bracket 10, a traction bar 20, a locking plate 30, an adjustable screw 30, a screw tightener 40, a support rod 50, a side support rod 51, The traction mechanism 60 , the fixing mechanism 70 and the first adjustable triangular bracket 80 .

[0044] The reset support 10 is a foldable support composed of the first square frame 11 and the second square frame 12. The two groups of square frames share the rotating shaft 90; hole 13, the traction bar 20 is fixed on the reset bracket 10 through a set of positioning holes; The opposite inner sides of the side bars of the group are respectively provided with locking buckles, through which the two groups of locking pieces 30 are respectively connected to the two groups of square frames to fix the reset support 10; The card slot changes the height of the reset bracket 10; the positioning hole 13 at different positions ca...

no. 1 example

[0054] The first embodiment is a ring-shaped three-axis traction reduction and fixation device, which is a three-axis anti-traction, and the affected limb is at the center of the three axes, so that the traction force line is the center of traction, which is conducive to fracture reduction; the fixing mechanism is fixed on the triangular shaft bracket , It will not be displaced with the traction, so there is no compression of the limbs by the traction device.

[0055] The present invention also includes such as Figure 4 The external fixation device 150 shown, the external fixation device 150 includes an external fixation screw 151 and a universal external fixation bracket; The cross-bar needle clamp is provided with screw holes and clamping slides; one end of the two pillars 153 is movably connected to the two ends of the cross-bar 154 respectively, and the other end is screwed into the screw holes of the two cross-bar needle clamps 152 respectively. The two screws are respe...

Embodiment 2

[0066] Such as figure 2 What is shown is the second embodiment provided by the present invention. Since embodiment 2 is a simple configuration of embodiment 1, the description of embodiment 2 is relatively simple. For relevant details, please refer to the description in embodiment 1.

[0067] In the second embodiment, including reset bracket 10, traction cross bar 20, locking plate 30, screw tightener 40, support rod 50, traction mechanism 60, fixing mechanism 70 and first adjustable triangular bracket 80; One end is screwed into the screw hole of the rotating shaft 90 , and the other end is connected to the fixing mechanism 70 .

[0068] The fixing mechanism 70 includes a bow-type fixing device and a second Kirschner wire 72, the bow-type fixing device includes a second traction bow 73 and a connecting sleeve 74; one end of the support rod 50 away from the reset bracket 10 is connected to the connecting sleeve 74, The connecting sleeve 74 is fixedly connected to the top end...

Abstract

The invention provides a skeletal traction reposition fixing device for treating limb fractures. The device comprises a repositioning bracket, a traction cross bar, a locking piece, a screw tightener,a supporting rod, a traction mechanism, a fixing mechanism and a first adjustable triangular bracket. Before traction, the direction of a traction force line can be adjusted by means of the repositioning bracket, the traction cross bar and the screw tightener; after traction, the direction of the traction force can be changed again by means of the triangular bracket by means of manual adjustment,so that the problem that the fracture end rotates and overturns inside and outside is solved; the repositioning bracket is of a triangular foldable structure, and is convenient to carry, quick to unfold during use and high in stability; the traction force is central traction by means of the triangular bracket, so that the fracture is repositioned favorably. According to the device provided by theinvention, fixing mechanisms are of immovable structures, so that the problem that the traction device presses limbs is avoided.

Description

technical field [0001] The invention relates to the medical field, in particular to a bone traction reduction and fixation device and method for treating limb fractures. Background technique [0002] Femur, tibia and other extremity fractures are common clinical fractures. During the treatment process, due to the influence of the muscles at the fracture site, the affected area will be shortened and deformed. It is difficult to reset, restore and maintain its length during the operation. Complications such as malunion and poor alignment of the lower limbs eventually lead to traumatic arthritis, which seriously affects the health of the patient. The basis of limb fracture treatment is reduction, on the basis of reduction, choose plaster fixation or intraoperative implant fixation. Traction is an important means to reduce fractures and restore the length of limbs, and is the most commonly used reduction method for closed reduction of limb fractures. [0003] The prior art pro...
