[0030] Combined with Figure 1-7 As shown, an auxiliary device for the treatment of intertrochanteric fractures of the femur can effectively lift and fix the bone while achieving accurate insertion and fixation of the Kirschner wire, ensuring the reduction and fixation effect, alleviating the patient's pain and effectively shortening the operation time.
[0031] The auxiliary device includes a propeller 1 and a fixing hook 2 connected to the propeller 1; specifically, the propeller 1 and the fixing hook 2 are detachably connected. In the present embodiment, the fixing hook 2 is arranged at the bottom of the propeller 1 and along the extension direction of the propeller 1. At the same time, the hook body 22 of the fixing hook 2 extends to the outside of the propeller 1.
[0032] The pusher 1 includes a fixed seat 11, a screw rod 12 and a locator 13. Specifically, the screw rod 12 is arranged along the length direction of the fixed seat 11 and is threadedly connected to the fixed seat 11. Specifically, the screw rod 12 has a columnar structure, and the screw rod 12 and the fixed seat 11 are threadedly connected. In this embodiment, a knob is provided at the end of the screw rod 12. By rotating the screw rod 12, the position of the locator 13 on the fixed seat 11 can be adjusted to facilitate accurate Kirschner wire insertion and fixation of the fracture through the locator 13.
[0033] Meanwhile, during implementation, the connection between the fixing hook 2 and the propeller 1 is achieved through the fixing seat 11 .
[0034] The locator 13 is connected to one end of the screw rod 12. In the present embodiment, the locator 13 is located at one end of the screw rod 12 close to the hook body 22 in the fixing hook 2, and the other end thereof extends to the outside of the pusher 1 and is provided with a knob. By rotating the screw rod 12, the locator 13 can be moved along the length direction of the pusher 1, and the position of the locator 13 on the pusher 1 can be adjusted to move the locator 13 to the fracture site, facilitate the insertion of the Kirschner wire, ensure the accuracy of the Kirschner wire insertion and fixing position, and thus ensure the reduction and fixation effect.
[0035] The positioner 13 includes a positioning seat 131 and a guide member 132 rotatably connected to the positioning seat 131. Specifically, a guide hole 133 is provided on the guide member 132. During use, the position of the positioner 13 is adjusted by the screw rod 12 to achieve the coordination between the guide hole 133 and the fracture site, thereby facilitating the insertion of the Kirschner wire.
[0036] Furthermore, the guide member 132 can rotate toward both sides of the positioning seat 131, and its single-side rotation range is 0 to 30°. In actual use, the guide member 132 can rotate toward both sides of the positioning seat 131 according to actual conditions to ensure that the guide hole 133 on the guide member 132 cooperates with the fracture.
[0037] A V-shaped bayonet 14 is disposed at the end of the fixing seat 11 , and a clamping column 15 is disposed at the bottom of the fixing seat 11 . Specifically, the clamping column 15 is located at the bottom of one end of the fixing seat 11 away from the V-shaped bayonet 14 .
[0038] The fixing hook 2 is provided with a slot 23 cooperating with the clamping column 15 , and the other end of the fixing hook 2 is telescopically provided with a clamping head 3 cooperating with the V-shaped bayonet 14 . Specifically, the clamping head 3 is provided with a damping rod 5 slidably cooperating with the fixing hook 2 .
[0039] In the specific implementation, the damping rod 5 on the clamping head 3 is set to achieve the separation between the clamping head 3 and the fixed hook 2, and then the fixing hook 2 and the fixing seat 11 are matched by the clamping column 15 and the clamping groove 23. Finally, the clamping head 3 is pushed to cooperate with the V-shaped bayonet 14 to achieve the connection between the fixing hook 2 and the fixing seat 11. At this time, the clamping head 3 abuts against the fixing hook 2 to ensure the stability of the connection between the fixing hook 2 and the fixing seat 11.
[0040] In addition, anti-slip grooves are provided on both sides of the clamping head 3 to facilitate the operation of the clamping head 3 .
[0041] The end of the fixing hook 2 is provided with a U-shaped opening groove 21. During implementation, the guide member 132 is arranged corresponding to the opening groove 21. During implementation, the guide hole 133 on the guide member 132 is arranged corresponding to the opening groove 21, which can facilitate the accurate insertion of the Kirschner wire through the guide hole 133 through the opening groove 21.
[0042] The fixing hook 2 is provided with a hook body 22 at the end of the opening slot 21, and the length of the hook body 22 on one side is greater than the length of the hook body 22 on the other side. Specifically, the structure of the hook body 22 can be set according to actual conditions. During implementation, the hook body 22 can be a needle body with an arc.
[0043] In specific implementation, the setting of the hook body 22 can realize the reduction of the fracture. The setting of hook bodies 22 of different lengths can facilitate the hooking and pulling of the sloped bone surface, which is beneficial to the reduction of the fracture.
[0044] When the utility model is implemented, the user holds the end of the auxiliary device away from the hook body 22, then hooks the fracture site through the hook body 22, and reduces the fracture to a more ideal position by pulling with the hook;
[0045] Then, by rotating the screw rod 12, the positioner 13 is adjusted, and the guide hole 133 on the guide member 132 is adjusted to the ideal position, and finally the Kirschner wire is inserted into the ideal position through the guide hole 133 and the opening slot 21.
[0046] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
