Description
Technical Field
The application relates to the technical field of medical equipment, in particular to a loop structure used in ligament or tendon injury repair surgery.
Background
Ligament or tendon injuries are one of the more common and serious injuries to human body movement, such as torn injuries to the anterior and posterior cruciate ligaments of the knee joint, which if not treated properly will cause instability of the knee joint and serious knee joint dysfunction. Therefore, surgery should be actively performed to reconstruct ligaments and their functions.
The loop is commonly used for fixing ligaments or tendons and bones in orthopedic reconstruction surgery, and can be used for anterior and posterior cruciate ligament reconstruction surgery of knee joints, dislocation fixation of acromioclavicular joints and the like. For example, in anterior-posterior cruciate ligament surgery of the knee joint, bone tunnels are drilled in the femur and tibia, respectively, and ligament grafts without bone pieces at both ends are fixed in the bone tunnels of the femur and tibia by using loop structures and screws.
The tab loop structures currently in use on the market are typically a tab titanium plate, which typically comprises a perforated titanium alloy plate, an adjustable or non-adjustable loop, a pull wire, and a flip wire. When the method is applied to ACL fracture or injury treatment, tunnels are drilled on the tibia and the femur, one end of an artificial tendon or ligament graft for ligament reconstruction is led to pass through a wire ring on a titanium alloy plate, then the artificial tendon or ligament graft is pulled through a traction wire on the titanium alloy plate and led to pass through tibial and femoral bone tracts until the titanium alloy plate reaches the surface of a cortex bone which can be overturned, and at the moment, the titanium alloy plate is suspended on the outer side of the femur through an overturning loop wire; the other end of the artificial tendon or ligament graft is passed through the bone tract of the tibia and a tendon and ligament fixing instrument (such as a tendon and ligament fixing screw, a U-shaped nail and the like, and a strap fixing plate can also be used) is fixed on the end of the tibia. Through fixing the femur end and the tibia end, the belt loop titanium plate is covered and wrapped with the tissue growing gradually, so that sufficient mechanical fixation can be provided, and the stability of the joint is recovered.
In the implantation process, the belt loop titanium plate needs to pass through the tunnel in the bone by using a traction wire, and the complex operation of turning the loop needs to be carried out by using a loop turning wire, so that the operation time is prolonged, and the error is easy to occur. In addition, the belt loop titanium plate pulls ligaments or tendons at the bone end, the ligaments or the tendons can pull the wire loop in the post-operation stretching activity, and the wire loop moves in the pulling process due to the fact that a gap exists between the bone tunnel and the wire loop, so that the titanium alloy plate is displaced, the pressure of the titanium alloy plate on the tunnel opening is uneven, and the wound is finally delayed to heal.
