Loop and manufacturing method thereof

Abstract

The invention provides a loop. The loop comprises a fixing plate and at least one sewing thread, wherein the sewing thread is wound into a first coil and a second coil and arranged on the first side of the fixing plate; the first end part of the first coil and the third end part of the second coil penetrate through different threading holes and are connected at the second side of the fixing plate to form a first fixing part, so the length of the first coil and the length of the second coil can be adjusted through the first fixing part under the action of a graft; and the second end part of the first coil passes through the plurality of threading holes to form at least one second fixing part at the second side of the fixing plate and then winds a part of the first coil and a part of the second coil at the first side of the fixing plate to form an adjusting part, so the length of the first coil and the length of the second coil can be adjusted under the action of human external force, and the first coil and the second coil can be effectively prevented from retreating under the action of pulling force of the graft. The invention further provides a manufacturing method of 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
