Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a proximal femoral nail. The proximal femoral nail includes a main nail, a fixing nail and an adjustingmember; the main nail has a proximal end, and the proximal end of the main nail is provided with a first through hole for the fixing nail to pass through; the fixing nail penetrates in the first through hole and can rotate in the first through hole; the fixing nail is provided with holes or grooves that can penetrate the two sides of the fixing nail; and the adjusting member passes through the holes or the grooves, and the two ends of the adjusting member respectively protrude from the lateral wall of the fixing nail. When the fixing nail has the defects of insufficient or excessive forward tilting, the defects of insufficient or excessive forward tilting can be made up by rotating the position of the fixing nail and placing the adjusting member, so that time-consuming and laborious repetitive operations due to the poor position of the fixing nail and damages to bone structures can be avoided; and the proximal femoral nail is simple in operation, high in tolerable error rate, less inX-ray exposure, high in operation efficiency and suitable for the fixation of various types of proximal femoral fractures.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a proximal femoral intramedullary nail. Background technique

[0002] Intramedullary nail is a commonly used device for internal fixation in orthopedics. It has the advantages of stably controlling the axial line of force at the fracture site, preventing rotational deformity of the fracture, and reducing the risk of implant fracture. It is widely used in the treatment of femoral fractures. The existing intramedullary nail structure includes a main nail fixed inside the femoral shaft, and a fixing nail obliquely passing through the proximal end of the main nail. One step treatment works.

[0003] At present, during the insertion of the intramedullary nail into the femur, since the human femur is wrapped by soft tissue layers such as skin, muscle, and tendon, it is difficult for the naked eye to directly observe and place the intramedullary nail at the best position of...
