Example Embodiment
[0012] For a better understanding and implementation, the present invention will be further described below with reference to the accompanying drawings: tibial intercondylar carina fracture memory alloy compression fixation needle, including a needle body 1, the needle body 1 is made of memory alloy material, and the front end is a hook 2. The tail is provided with a thread 3, which is matched and connected with the pressure nut 4. The body of the pressure nut 4 is tubular with internal threads, and the tail end is enlarged, which is convenient to block the nut from entering the bone tunnel.
[0013] The pressure fixation needle is made of memory alloy and has a rigid sharp-pointed hook 2. The hook 2 is hook-shaped at room temperature. After soaking in ice water, it can be straightened with equipment. After reheating, it will become hook-shaped due to metal memory. , So as to hook the fracture block, the tail of the fixation needle is threaded, and when the compression nut rotates...
