[0002] Proximal femur fractures are fractures of the proximal thighbone (femur), usually caused by severe external force or osteoporosis. Treatment of proximal femur fractures often requires surgical intervention to restore the anatomy and function of the fracture site.

[0003] The auxiliary positioning device is a tool used in proximal femoral fracture surgery to help doctors accurately locate the fractured bone segments, assist in reduction, and stabilize the fracture site. It can provide precise navigation and guidance to help doctors perform better surgical operations.

[0004] In traditional orthopedic work, it is often difficult to manually reduce the femoral fracture during surgery, and the reduction cannot be maintained. During the operation, fluoroscopy is required, and the surgeon's hands cannot maintain the position at this time. In clinical practice, doctors cannot maintain the position of the fracture for a long time after manually reducing it during femoral fracture surgery.

[0005] Therefore, in order to solve the above problems, a proximal femoral fracture auxiliary positioning device capable of clamping and limiting movement during surgery is proposed. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] (1) In order to facilitate the movement of the clamping and limiting device for the reduction rod during surgery, a fixing device is provided at one end of the handle. When in use, when it is necessary to fix the rod body to prevent the device from moving on the surface of the rod body, a switch is used to control the electric telescopic rod to move telescopically, so that the electric telescopic rod drives the fixed splint to move, so that the fixed splint contacts the surface of the rod body, and the rod body is fixed by the fixed splint to prevent the device from moving.

[0020] (2) In order to be able to perform subtle movement and adjustment of the rod body during use, to push the rod body to move, to assist the doctor in more accurately controlling the movement of the guide needle or guide wire, and to perform precise surgical operations, a protective ring is provided on one side of the fixing device, and an adjustment device is adapted to be provided inside the protective ring. During use, when the doctor needs to slightly move the guide wire or guide needle, the doctor rotates the adjustment wheel so that the rotation of the adjustment wheel drives the adjustment ring to rotate. The adjustment ring drives the moving thread on the surface of the rod body to rotate and move during the rotation process through the adjustment thread, so as to slightly move the rod body and the device. The friction strips provided on the surface of the adjustment wheel increase the use efficiency and prevent hand slippage. The adjustment shafts at both ends of the adjustment ring limit the adjustment wheel and increase the rotation efficiency.

[0021] (3) In order to facilitate the clamping of the rod body and ensure the stability of the rod body during operation, a clamping device is provided on one side of the protective ring, and a limiting device is provided on the other side of the protective ring. When in use, the rod body is passed through the device so that one end of the clamping rod contacts the surface of the rod body, so that the rod body pushes the clamping rod to expand outward along the first clamping axis. When the clamping rod expands outward, the second limiting plate is driven to move through the second clamping axis, and the second limiting plate drives the second limiting column to move, so that the second limiting column drives the limiting spring to deform. After the limiting spring is deformed, it applies elastic force to the clamping rod, so that the clamping rod applies pressure to the surface of the rod body, clamps and limits the rod body, and ensures the stability of the rod body.
