Multi-tunnel guide positioning system in knee-joint multiple ligament injury surgery

Abstract

The invention discloses a multi-tunnel guide positioning system in a knee-joint multiple ligament injury surgery. The multi-tunnel guide positioning system comprises a longitudinal bow positioner, a transverse bow positioner, a longitudinal kirschner wire guide sleeve, a transverse kirschner wire guide sleeve and a tunnel space adjustment sheet, wherein the longitudinal bow positioner, the tunnelspace adjustment sheet and the transverse bow positioner are sequentially connected through connecting bolts from top to bottom, the longitudinal kirschner wire guide sleeve is connected with the longitudinal bow positioner through a longitudinal locking screw, and the transverse kirschner wire guide sleeve is connected with the transverse bow positioner through a transverse locking screw. The multi-tunnel guide positioning system can provide accurate bone tunnel guide management for surgeons, is used for positioning guide management of a plurality of bone tunnels in reconstruction of a plurality of ligaments under arthroscopy during surgical treatment of knee-joint multiple ligament injury, and avoids mutual crossing and interference of the tunnels on the premise of accurately positioningbone tunnel inlets according to surgical requirements.

Description

technical field [0001] The invention belongs to the field of knee joint ligament repair in clinical medicine, and in particular relates to a multi-tunnel guiding and positioning system in operation for multiple knee joint ligament injuries. Background technique [0002] The knee joint is the largest joint in the human body with the most complex structure and the most complex movement mode. The stability of the knee joint is jointly maintained by the bony structure of the knee joint, the tendon and ligament structure outside the joint, and the internal structure of the joint. Bone structures include the lateral collateral ligament (LCL), popliteus tendon (PT) and popliteofibular ligament (PFL), anterolateral structures (ALL), medial collateral ligament (MCL), patellofemoral ligament (MPFL), etc. Anterior cruciate ligament (ACL), posterior cruciate ligament (PCL). When the knee joint is severely injured and dislocated and the above-mentioned ligaments are injured multiple tim...

AI Technical Summary

Problems solved by technology

[0003] At present, the method to restore the stability of the knee joint is mainly to reconstruct the related ligaments under knee arthroscopy and partial open surgery. During the operation, more than one anatomical or functional reconstruction needs to be established in a limited space (such as the inner or outer side of the femur) Bone tunnels required for positioning, and these bone tunnels are absolutely not allowed to cross or interfere with each other, otherwise the reconstructed ligament structure may be broken or the fixation may fail, resulting in the failure of the operation, and even the most experienced doctor cannot guarantee more under visual inspection. The two tunnels never intersect or interfere with each other, so it is necessary to develop a simple, practical and easy-to-operate mechanical positioning and navigation management system to ensure that multiple bone tunnels never intersect or interfere with each other during the operation.
