[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-6 The utility model provides a technical solution: a fracture postoperative corrector, comprising a first bracket 100 and a second bracket 200 respectively worn on the outside of the patient's forearm and upper arm, and an assembly part 300 for connecting the first bracket 100 and the second bracket 200 and two positioning mechanisms 400 respectively assembled on the first bracket 100 and the second bracket 200. The first bracket 100 and the second bracket 200 have the same structure. The first bracket 100 comprises two symmetrically distributed end blocks 110 and a first slide bar 120 and a second slide bar 130 which are distributed in parallel and vertically arranged between the two end blocks 110. The second slide bar 130 is fixedly installed at the bottom between the two end blocks 110. The top of the inner side of the block 110 is provided with a slide groove 1110 distributed in the vertical direction. The first slide bar 120 is slidably clamped between the two end blocks 110 through two sliders 140 respectively arranged at both ends thereof. The positioning mechanism 400 includes a first mounting seat 410 and a second mounting seat 420 respectively sleeved on the first slide bar 120 and the second slide bar 130, and a screw rod 430 threadedly penetrated through the first mounting seat 410, a knob 440 is fixedly installed on the top end of the screw rod 430, and the bottom end of the screw rod 430 penetrates the second mounting seat 420 and is rotatably connected to the second mounting seat 420 through a bearing, and two symmetrically distributed clamping components 450 are respectively provided on the first mounting seat 410 and the second mounting seat 420.

[0036] Based on the above-mentioned structural setting, the postoperative fracture corrector is composed of a first bracket 100, a second bracket 200, an assembly part 300 and two positioning mechanisms 400, wherein the first bracket 100 is arranged on the outside of the patient's forearm, and the patient's forearm is clamped and positioned by means of the positioning mechanism 400 assembled on the first bracket 100, the second bracket 200 is arranged on the outside of the patient's upper arm, and the patient's upper arm is clamped and positioned by means of the positioning mechanism 400 assembled on the second bracket 200, and the first bracket 100 and the second bracket 200 are fixedly connected by the assembly part 300. Specifically, during use, the operator respectively sets up the first bracket 100 and the second bracket 200 on the outside of the patient's forearm and upper arm, and then respectively positions and clamps the patient's forearm and upper arm with the help of the two positioning mechanisms 400. During the positioning and clamping process The operator turns the knob 440, and under the limiting action of the first slide bar 120 between the two slide grooves 1110, the clamping assembly 450 located at the top moves downward to approach the clamping assembly 450 located at the bottom, so that the two clamping assemblies 450 clamp and position the patient's part to be clamped. Finally, the operator uses the assembly part 300 to achieve a fixed connection between the first bracket 100 and the second bracket 200, thereby completing the wearing operation of the corrector on the patient's correction part. The post-operative corrector for fractures is provided with a positioning mechanism 400 on both the first bracket 100 and the second bracket 200, and the positioning mechanism 400 replaces the traditional Velcro to fix the patient's correction part. During the wearing process of the corrector, no traction operation is required, which avoids accidental touching of the patient's correction part during operation, ensures the correction effect, and is convenient for disassembly and assembly.

[0037] Furthermore, the first slide bar 120 and the second slide bar 130 are assembled by coaxially connecting a plurality of unit rods 1210, one end of the unit rod 1210 is provided with a threaded column 1220, and the other end of the unit rod 1210 is provided with a threaded hole 1230 threadably matched with the threaded column 1220. In view of the wearing requirements of different patients, the required lengths of the first bracket 100 and the second bracket 200 may be different. Preferably, by setting the first slide bar 120 and the second slide bar 130 to be composed of a plurality of freely spliced ​​unit rods 1210, in actual use, the lengths of the first slide bar 120 and the second slide bar 130 can be adjusted according to the requirements, and the use is flexible.

[0038] Furthermore, the assembly 300 includes a first L-shaped seat 310, a second L-shaped seat 320 and a bolt 330 for limiting and locking the two. The first L-shaped seat 310 is fixedly connected to the first bracket 100, and the second L-shaped seat 320 is fixedly connected to the second bracket 200. Figure 2As shown, when the first bracket 100 and the second bracket 200 are in the same plane state, the first L-shaped seat 310 and the second L-shaped seat 320 are centrally symmetrically distributed. During use, when the bolt 330 is not tightened, it plays a role similar to a pin shaft. The first bracket 100 and the second bracket 200 are rotatably connected. The operator can adjust the connection angle between the two in real time according to usage requirements. After completing the positioning and wearing of the first bracket 100 and the second bracket 200, the operator can tighten the bolt 330. At this time, the bolt 330 serves as a fixed connection between the first bracket 100 and the second bracket 200.

[0039] Furthermore, the clamping assembly 450 includes two fixed seats 4510 and two guide pillars 4520. The two guide pillars 4520 are movably inserted into the two fixed seats 4510 respectively, and screws 4530 for limiting and locking the guide pillars 4520 are threadedly inserted through the tops of the two fixed seats 4510. The two guide pillars 4520 are parallel to each other and their axes are in the same horizontal plane. The inner ends of the two guide pillars 4520 are installed with splints 4540, and the inner sides of the splints 4540 are glued and covered with gaskets 4550. Among them, two guide columns 4520 that are movable and pass through the two fixing seats 4510 respectively can realize the adjustment of the distance between the splint 4540 and the two fixing seats 4510, and then the clamping coverage of the splint 4540 can be adjusted in real time, and the guide columns 4520 are locked and fixed with the help of screws 4530 to adapt to the clamping needs of different patients to ensure that the clamping is firm and stable. The setting of the pad 4550 avoids the splint 4540 from directly acting on the clamping part of the patient, thereby improving the wearing comfort.

[0040] Furthermore, an auxiliary handle 500 is provided on the side of the first bracket 100 away from the second bracket 200 for the patient to hold, and the auxiliary handle 500 is connected to the first bracket 100 through a connecting plate 510. The auxiliary handle 500 can provide auxiliary support for the patient's hand, and the patient can reduce hand fatigue by holding the auxiliary handle 500, thereby improving the patient's comfort and use experience.
