Fixing system used for femoral fracture

Abstract

The invention provides a fixing system used for femoral fracture. The system comprises an intramedullary nail, a femoral fixing assembly and a connecting assembly. The above intramedullary nail further contains an upper part, a lower part, a hollow pipeline and an oblique channel. The femoral fixing assembly penetrates through the oblique channel and further contains a front part and a back part, both of which are integrally formed. The connecting assembly is arranged in the upper part of the intramedullary nail and contains a locking unit and a fixing unit. The locking unit is embedded on the fixing unit and pushes the fixing unit such that the fixing unit is joined with the back part of the femoral fixing assembly.

Description

technical field [0001] The invention relates to a fixation system, in particular to a fixation system for femur fractures. Background technique [0002] The bones of different parts of the human body have different shapes and complex structures. In the event of fractures and other injuries, the medical treatment and rehabilitation methods usually need to be given appropriate treatment based on the bone structure of the injured part. When the fractured part is close to the joint When it is not suitable to use plaster fixation, devices and bone nails are usually used as fixation for fracture treatment. [0003] Taking hip fracture as an example, when the patient is subjected to high-energy trauma, such as a car accident, strong collision or falling from a height; or low-energy trauma, such as slipping or falling, the proximal femur may be injured. Fractures caused by twists and turns (for example, femoral head fracture, femoral neck fracture, and intertrochanteric fracture or...

Problems solved by technology

We can know from the above that screwdrivers or lag screws cannot be used for the same intramedullary nail

[0006] Furthermore, because the screwdriver or lag screw fell off in the intramedullary nail device used in the past, after the patient was implanted with the above-mentioned fixing device, the femoral fracture site was affected by the screwdriver or lag screw falling off, resulting in postoperative Malunion, failure to heal, or other complications at the fracture site
