Problems solved by technology

[0007] The purpose of the present invention is to provide a positioning device for positioning the cruciate ligament of the knee joint. The positioning device covers the tibia on the outside of the knee joint tunnel, that is, it is introduced into the positioning device through the posterior approach, which solves the blocking of the intercondylar concave tissue. The problem of insufficient positioning depth of the high intercondylar ridge locator makes the operation easier and shortens the operation time

Abstract

The invention provides a positioning device which is used for positioning a knee joint cruciate ligament. The positioning device comprises a connecting part, a fixing part and a guide part, wherein the fixing part and the guide part are positioned at the two ends of the connecting part; when positioning is performed in a knee joint tunnel, a hook part is directly propped against a first side of the tunnel without passing through the inside of the tunnel; the guide part is propped against a second side of the tunnel; the connecting part coats the outer side surface of a shank bone, so that the positioning device coats the shank bone from the outside of the tunnel, namely when positioning is performed in the tunnel, a medial arthroscopic approach is established; the positioning device enters through the posterior medial arthroscopic approach to position, so that the problem of insufficient depth of condylar concave tissue blocking, namely intercondylar crest higher positioner positioning, is solved, further, the surgical operation is simpler, and the surgical time is shortened.

Description

technical field [0001] The invention relates to the field of medical operations, in particular to a positioning device applied to the minimally invasive operation of cruciate ligament of knee joint and its insertion point fracture. Background technique [0002] With the progress of society and the development of medical level, minimally invasive surgery will become the trend. Arthroscopic surgery has developed rapidly in recent years. The progress of technology is inseparable from the innovation of equipment. Good equipment can greatly reduce the difficulty of surgery and improve the quality of surgery. Suffering brings greater benefits. [0003] There are two cruciate ligaments in the knee joint. The anterior cruciate ligament is attached to the anterior intercondylar fossa of the tibia, obliquely to the posterolateral superiority, inserts behind the medial surface of the lateral femoral condyle, and has the function of restraining the anterior displacement of the tibia. ...
