Tension band system matched with proximal femoral nail

Abstract

The invention provides a tension band system matched with a proximal femoral nail, and relates to the technical field of medical equipment. The tension band system solves the technical problem that the proximal femoral nail is likely to break due to concentrated stress. The tension band system matched with the proximal femoral nail comprises a distal loop, a proximal loop, a tension band and a lock catch, wherein the proximal loop is detachably arranged on the top of the proximal femoral nail, the distal loop is detachably arranged at the lower part of the proximal femoral nail, the tension band is a closed annular band, the two ends of the tension band are connected with the proximal loop and the distal loop respectively, and the lock catch is connected to the tension band between the distal loop and the proximal loop. By reconstructing an anti-tension structure on the outer side of the proximal femoral nail, the stress concentrated on the proximal femoral nail is transferred to and concentrated on the tension band system. The tension band system is made of a plurality of strands of titanium cables, thus having great resistance to tension, thereby indirectly increasing the strength of the proximal femoral nail, prolonging the service life of the proximal femoral nail, and reducing the risk of fracture fixation failure.

AI Technical Summary

Benefits of technology

This new technology allows for better control over bone growth during surgery by creating an implant that can resist tensile forces applied externally or internally from inside the body's marrow canal. It uses several layers of metal with different properties such as aluminum copper wire twisted together at specific angles around its core. These technical improvements make it more effective than existing methods while reducing patient discomfort caused by excessive force being transferred through these materials.

Problems solved by technology

This patented technology solves issues with treatments involving implants placed inside the body when it becomes necessary due to partial hip joints caused during orthopedic surgery procedures like knees replacement surgeries. These techniques involve inserting an extrudable material into the damaged area around the base of each thighbone segment through holes made in its outer surface before attaching metal plates onto them. However, these methods have limitations because they may lead to painful wounds from sharp ends called pullers.
