Abstract

The invention discloses an ACL multi-beam reconstruction technology for a knee-joint ACL (anterior cruciate ligament) for department of orthopaedics, and the technology comprises a thighbone end footprint positioner, a door-type guide frame, a positioning operation channel sleeve, a positioning operation channel sleeve guider, a central hole positioner, an orthopaedics department hollow drill, a cancellous bone extractor, a 12-point positioning guider, a 3 / 9 point positioning guider, a shin bone end arc-shaped positioning guider, a shin bone end central hole positioning guider, and a shin bone end trepanning guider. The technology is convenient to use, can achieve the protogenetic reconstruction of the knee-joint ACL conveniently, achieves the complete covering of a deserved footprint region, achieves the function of the intersecting of a front beam and a rear beam, and achieves the protogenetic reconstruction after repeated damage.

Description

technical field [0001] The invention belongs to the field of medical tools, and in particular relates to an orthopedic knee joint ACL multi-bundle reconstruction technique and its application. Background technique [0002] The anterior cruciate ligament of the knee joint, referred to as ACL, refers to the dense connective tissue attached to the medial surface of the femoral condyle of the knee joint. The ligament structure formed by the depression in front of the intercondylar crest of the tibial plateau. There are blood vessels nourishing and nerve distribution at both ends of the femoral and tibial insertions. The main function is to control the abnormal forward movement and rotation of the tibia of the knee joint, and cooperate with other static and dynamic stabilization devices of the knee joint to maintain the stability of the knee joint. But once it is damaged, it is a very troublesome thing to repair. Contents of the invention [0003] The technical problem to be ...
