Problems solved by technology

However, the operation technique under the microscope is complicated, and two bone tunnels need to be drilled on the femur and tibia respectively, and the consumption of internal fixation consumables is twice that of the single-tunnel technique.
Due to the large loss of bone volume after drilling the 4 tunnels during the operation, the revision is particularly difficult. Some patients need to go through the first stage

Abstract

The invention discloses an orthopaedics department knee joint anterior cruciate ligament dissection reestablishment system which comprises a thighbone end locator, a central hole locator, a 8/9 mm hollow drill, a 6/12 point hole fixing device, a 6 point hole sleeve, a 3/9 point hole fixing device, a 3/9 point hole leveling device, a working sleeve, a working sleeve introducer, a shin bone end locator, a kirschner wire and a guiding needle. The orthopaedics department knee joint anterior cruciate ligament dissection reestablishment system is simple in structure, convenient to use, capable of reestablishing the anterior cruciate ligament of a knee joint conveniently.

Description

technical field [0001] The present invention relates to the field of single-tunnel anatomical beam splitting of anterior cruciate ligament femur and tibial insertion foot print area and the reconstruction system field of autologous or allogeneic tendon with preset original tension, in particular to an orthopedic knee anatomical reconstruction system of anterior cruciate ligament and its application method . 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...
