Loops and methods of making them

Abstract

The present invention provides an annulus, comprising a fixing plate and at least one suture, the suture is wound into a first coil and a second coil and arranged on the first side of the fixing plate, the first coil The first end and the third end of the second coil pass through different threading holes and are connected on the second side of the fixing plate to form a first fixing part, so that the graft passes through the first fixing part under the action of the graft. The fixing part can adjust the length of the first coil and the length of the second coil, and the second end of the first coil passes through several threading holes to form at least one second fixing on the second side of the fixing plate. Part of the first coil and part of the second coil are wound around the first side of the fixing plate to form an adjustment part, so that the length of the first coil and the second coil can be adjusted under the action of artificial external force , and can effectively prevent the first coil and the second coil from retreating under the pulling force of the graft. The invention also provides a method for making the loop.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a loop and a manufacturing method thereof. Background technique [0002] The loops are used for the fixation of ligaments or tendons and bones in orthopedic reconstruction operations, and are often used in reconstruction operations of the anterior and posterior cruciate ligaments of the knee joint, and fixation of acromioclavicular joint dislocations, etc. For example, in cruciate ligament surgery, bone tunnels need to be drilled on the femur and tibia respectively, and ligament grafts without bone fragments at both ends are fixed in the bone tunnels of the femur and tibia using titanium plates with loops and screws. [0003] In cruciate ligament reconstruction of the knee joint, the ligament graft should fill the femoral tunnel as completely as possible. The existing titanium plate with loop is divided into fixed-length titanium plate with loop and adjustable titanium plate with l...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of ring and its manufacture method, to solve the problem that the length of the coil in the fixed-length titanium plate with loop cannot be adjusted in the prior art, and the coil of the adjustable titanium plate with loop is easy to be placed on the graft. Retraction under the reaction force, which is not conducive to the problem of surgery
