Abstract

The invention provides a knee bending support for a tibia intramedullary nail operation. According to the invention, the knee bending support comprises a base provided with a guide chute formed at oneside; a knee bending device is arranged on the base; the knee bending device comprises a rotating device, and a first supporting plate and a second supporting plate which are connected with the rotating device and are respectively positioned on two sides of the rotating device; the bottom of the first supporting plate and the bottom of the second supporting plate are rotationally connected with afirst fixing plate and a second fixing plate correspondingly, an adjusting device arranged in the guide sliding groove is fixed to the bottom of the second fixing plate, and the adjusting device adjusts an included angle between the first supporting plate and the second supporting plate. The included angle between the thigh and the shank is adjusted through the adjusting device, so that adjustment is more accurate, secondary damage to the fracture of a patient due to manual adjustment is avoided, manpower input is reduced, and operation efficiency is improved.

Description

Technical field [0001] The invention relates to the field of orthopedic medical auxiliary equipment, in particular to a knee bending bracket for tibial intramedullary nail surgery. Background technique [0002] The tibial shaft is located in the lower leg and is one of the most vulnerable parts of fractures, so tibial shaft fractures are more common. For displaced tibial shaft fractures, the currently commonly used surgical method is closed reduction and internal fixation with tibial hinge intramedullary nails. For the commonly used subpatellar approach tibial intramedullary nail surgery, an assistant is required during the operation to keep the affected limb in a 90-120 degree flexion position to facilitate the insertion of the intramedullary nail. At the same time, another assistant is needed to fix the ankle joint, keep the calf traction, and maintain the line of force to ensure the smooth insertion of the intramedullary nail. During the operation, two assistants are needed ...
