AI Technical Summary

Technical Problem

In the prior art, bone cement is required to be added for filling and fixing when setting intramedullary nails, resulting in the intramedullary nails being unable to be removed from the femur.

Method used

A proximal femur intramedullary nail is designed, including a fixing part and a fixing component. The fixing barrel of the fixing part can be arranged in the femoral body inclined, the fastener and the locking member are both arranged in the fixing barrel, and there is an angle between the fastener and the locking member. The first rod segment and the second rod segment are removably arranged, the first rod segment is connected to the femoral head through the proximal femur, and the second rod segment is arranged in the proximal femur, and the first end of the locking member passes through the proximal femur and is connected to the femoral head.

Benefits of technology

It facilitates the installation and disassembly of intramedullary nails without adding bone cement, improves the fixation effect on the femoral head, and facilitates the recovery of the fracture site at the proximal femur and bone growth.

Abstract

The present invention provides a proximal femoral intramedullary nail, which comprises: a fixing portion, comprising a fixing tube, the fixing tube is configured to be obliquely inserted into the main body of the femur; a fixing assembly, comprising a fastener and a locking member, the fastener and the locking member are both inserted into the fixing tube, there is an angle between the fastener and the locking member, the fastener comprises a first rod segment and a second rod segment, the axis of the first rod segment coincides with the axis of the second rod segment, the first rod segment and the second rod segment are detachably arranged, the first rod segment is configured to pass through the proximal femur and connect with the femoral head, the second rod segment is inserted into the proximal femur, the first end of the locking member is configured to pass through the proximal femur and connect with the femoral head, and the second end of the locking member is inserted into the second rod segment. The technical solution provided by the present application can solve the problem in the related art that when setting the intramedullary nail, bone cement needs to be added for filling and fixing, which leads to the inability to remove the intramedullary nail from the femur.
