The entire contents of this application are incorporated herein by reference.

Technical field

The present application relates to the field of medical device technology, and in particular to a dynamic pressure ligament reconstruction system.

Background technique

The knee cruciate ligament, also known as the cruciate ligament, is located between the inside and outside of the femur, two front and back, intersecting each other. The anterior cruciate ligament originates from the posterior aspect of the femoral condyle, and terminates in the anterior aspect of the tibial spine forward, inward, and lower. The posterior cruciate ligament originates from the anterior portion of the intercondylar fossa and terminates posteriorly, laterally, and posteriorly to the posterior aspect of the tibial spine. The anterior cruciate ligament prevents the humerus from shifting forward; the posterior cruciate ligament prevents the humerus from shifting backward. The anterior cruciate ligament injury is mostly caused by over-extension violence or abduction of the external calf. The tear can occur at the starting point, body, or dead point. Often combined with avulsion fracture of the tibial spine. The posterior cruciate ligament injury is mostly caused by violence directly hitting the front of the upper end of the humerus. The tear can occur at the attachment of the femur or tibia. In the case of injury, the knee joint is in a semi-flexion position and can be combined with anterior ligament injury.

In the course of implementing the present application, the inventors have found that when the cruciate ligament is damaged, it causes instability of the joint and causes deterioration of other tissues. Due to the poor self-healing ability of the ligament, the damaged ligament must be replaced by surgery to restore its function. Although there are ways to fix the ligament by screw or suspension in the prior art, it is limited by the limitations of the reconstruction system, and the bungee effect and the wiper effect caused by the unstable fixation of the transplanted tendon often occur, which may affect the subsequent ligament reconstruction effect. .
