Intraoperative multi-tunnel guidance management system for multiple ligament injury of knee joint

Abstract

The invention discloses a multi-tunnel guiding management system in multiple ligament injuries of the knee joint, which includes a longitudinal arc locator, a transverse arc locator, a longitudinal Kirschner wire guiding sleeve, a transverse Kirschner wire guiding sleeve, and a tunnel spacing adjustment sheet. The longitudinal bow-shaped positioner, the tunnel spacing adjustment piece and the transverse bow-shaped positioner are sequentially connected by connecting bolts from top to bottom, the longitudinal Kirschner wire guide sleeve and the longitudinal bow-shaped positioner are connected by longitudinal locking screws, and the transverse The Kirschner wire guiding sleeve is connected with the transverse bow positioner through a transverse locking screw. The present invention can provide surgeons with accurate guide management of bone tunnels, and is used for positioning and guide management of multiple bone tunnels when multiple ligaments are reconstructed under arthroscopy in the surgical treatment of multiple ligament injuries of the knee joint, so as to achieve accurate positioning of bone tunnels according to surgical requirements The purpose of avoiding mutual crossing or interference between tunnels under the premise of the entrance.

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 management 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 times, t...

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.
