Anatomical locked hook plate with memory alloy

Abstract

The invention relates to an anatomical locked hook plate with memory alloy. The anatomical locked hook plate comprises nail hooks with protruding near ends, a locking plate and a far end embracing device. The head of the hook plate is in a semiarc shape, and the long nail hooks of 0.5 cm are arranged on part of a protrusion (2), and can be directly fixed in the sclerotin. The near end of the hook plate is in a sector shape capable of completely embracing the greater trochanter, and five to seven locking screw holes and four to six conch type needle holes are formed. The far end embracing device is a memory alloy embracing device, semicircular fixed clamping rings are arranged in the far end embracing device, sharp protruding clamping grooves are formed in the clamping rings, and the hook plate can be closely combined with the sclerotin. A fixed shaft is arranged outside the far end embracing device and connected with the locking plate into a whole, locking holes are formed in the fixed shaft, and locking screws can be fixed when necessary. The anatomical locked hook plate with the memory alloy combines the advantages of the memory alloy embracing device, an anatomical steel plate, the locking steel plate and a tension belt, and has the advantages of being integrated, easy to operate, firm in fixing and the like.

Description

technical field [0001] The invention relates to an anatomical locking hook plate with memory alloy. Background technique [0002] Prosthesis fracture during or after hip replacement is one of the more common orthopedic complex operations in recent years. Since periprosthetic fractures are often accompanied by severe osteoporosis and other lesions, it is very difficult to choose a treatment method after fracture. At present, the more commonly used methods include single cortical locking plate, steel wire binding, memory alloy embracing device and other methods of treatment. However, each method has certain disadvantages, especially when the fracture range around the prosthesis is wide, involving the greater trochanter of the femur and the fracture of the femoral shaft at the same time, the clinical treatment is very difficult. The comprehensive application of various methods not only prolongs the surgical treatment, but also increases the risk of surgery Feeling the risk, at...

However, each method has certain disadvantages, especially when the fracture range around the prosthesis is wide, involving the greater trochanter of the femur and the fracture of the femoral shaft at the same time, the clinical treatment is very difficult. The comprehensive application of various methods not only prolongs the surgical treatment, but also increases the risk of surgery Feeling the risk, at the same time, due to the lack of firm fixation, postoperative patients cannot perform joint function training early, which has a certain impact on the recovery of postoperative joint function
