Description
Technical Field
The utility model relates to a tibia positioner used in arthroscope posterior cruciate ligament avulsion fracture ligation reduction operation, belonging to the technical field of orthopedic medical instruments.
Background
The posterior cruciate ligament begins at the medial condylar lateral surface of the femur and ends posteriorly of the intercondylar process of the tibia, with the primary function of limiting posterior movement of the tibia relative to the femur. Because of the wide range of attachment and strong adhesion of the posterior cruciate ligament to the tibia, traumatic avulsion fractures typically occur at this site. Such injuries can lead to instability of the knee joint, which, if not properly treated, can accelerate knee degeneration in the long term. In order to restore the knee joint structure and stability, the posterior cruciate ligament avulsion fracture block needs to be reset by actively adopting arthroscope ligation.
The difficulty of the avulsion and fracture of the cruciate ligament after the reduction of the avulsion under the arthroscope is that the broken line below the avulsion bone block is positioned at the rear side of the proximal tibia and below the tibial plateau (as shown in fig. 5), the position of the part is deep, the view under the arthroscope is poor, and a double tunnel is usually required to be established, namely, a tibial bone tunnel is respectively established at the inner side and the outer side below the avulsion bone block for 8-shaped ligation fixation so as to achieve better reduction effect (as shown in fig. 6), and the operation difficulty of a clinician is increased. Because no special localizer is provided, most of the current instruments for establishing the tibial bone tunnel by the posterior cruciate ligament avulsion fracture still use the tibial localizer when the posterior cruciate ligament is rebuilt, common manufacturers are schlegel, qisheng, arthrex and the like, all locate the lower part of the posterior cruciate ligament avulsion fracture block by the localizer, and respectively drive guide pins at the inner side and the outer side below the fracture line, and then use tibial bone tunnel drill bits with corresponding thickness to establish the tibial bone tunnel. For posterior cruciate ligament avulsion fracture ligation reduction surgery, accurate bone canal positioning is the most important guarantee of surgery success. At present, the locator is needed to be held by an operator in the locator operation during the reconstruction of the posterior cruciate ligament, the position is maintained unchanged, and meanwhile, the pilot needle is drilled by the hand. This procedure is highly demanding on the stability of the medical personnel's hand, and once the assistant moves while drilling the lead, it may cause a deviation in the lead position, increasing the likelihood of surgical failure. Clinically, for patients with avulsion and fracture of the posterior cruciate ligament, the patients are often young and middle-aged patients, the bone strength is good, the tibial cortex is thick, the drilling difficulty is high, when the drilling is not smooth, operators are often difficult to keep the position for a long time, an assistant is also difficult to keep the angle unchanged all the time, and all the factors can lead to the change of the direction of the guide pin and the emergence point, so that the operation effect is influenced. And the bone broken line below the posterior cruciate ligament avulsion bone piece is deeper than the posterior cruciate ligament dead point position, and the tibia locator when using posterior cruciate ligament to rebuild is because its tubular fixed arm is shorter, can not pinpoint in avulsion bone broken line below, often because of its length is shorter, fixes on the fracture line, is difficult to anatomical reduction when finally leading to the ligature to reset.
In addition, after the tibial bone tunnel on one side is prepared by using the tibial locator reconstructed by the posterior cruciate ligament, the tibial bone tunnel on the other side is also needed to be prepared again, and the preparation processes of the two bone tunnels are completely the same, so that the process is time-consuming and labor-consuming due to the limited space behind the knee joint under the arthroscope, the operation efficiency is reduced, the labor intensity of medical staff and the pain of patients are increased, and the operation effect cannot be ensured. Therefore, the tibia localizer which is accurate in localization and convenient to operate and is suitable for the avulsion and fracture of the cruciate ligament behind the knee joint is very necessary.
