Problems solved by technology

Therefore, only a small number of large hospitals in China can carry out this operation safely and effectively. For most grass-roots hospitals engaged in trauma treatment, knee dislocations involving PCL rupture often require clinical surgical treatment, but the aforementioned two Reasons hinder the promotion of PCL reconstruction surgery in primary hospitals

Abstract

The invention discloses an anatomic reconstruction system for posterior cruciate ligaments of orthopaedic knee joints, which comprises a tibia-end positioner, a center hole positioner, a tibia positioner fixed guide sleeve, a tibia wing guide sleeve, a hollow drill, a conduit tube, a thread guide, a kirschner wire and a guide pin. The anatomic reconstruction system disclosed by the invention is simple in structure and convenient to use, and can conveniently reconstruct posterior cruciate ligaments of knee joints.

Description

technical field [0001] The invention relates to the field of a combined tool system for orthopedic fixed anatomical reconstruction of tibial insertion footprint area, in particular to an orthopedic anatomical reconstruction system of the posterior cruciate ligament of the knee joint and a method of use thereof. Background technique [0002] Posterior cruciate ligament, PCL for short, refers to the dense collagen fiber tissue issued behind the articular cartilage on the lateral surface of the medial femoral condyle of the human knee joint, from the anterior, superior, and medial obliques of the intercondylar fossa to the posterior, inferior, and lateral of the tibial plateau , a ligamentous structure formed by inserting on the posterior border of the intercondylar crest of the tibial plateau. There are nourishing blood vessels and nerve distribution at both ends of its femoral and tibial insertions, and its main function is to prevent the subsidence of the tibia, and maintain...
