Loop and manufacturing method thereof

Abstract

The invention provides a loop which comprises a fixing plate and a suture line, wherein at least two threading holes are formed in the fixing plate, the suture line is wound into a first coil and a second coil, the first coil and the second coil are arranged on the same side of the fixing plate, the two ends of the first coil and the two ends of the second coil penetrate through the threading holes, the two end parts of the first coil are movably connected to form a first elastic part, the third end part of the second coil is connected with the first end part of the first coil to form a fixingpart, and the fixing part is used for pressing the fourth end part of the second coil to form a second elastic part. By arrangement of the first elastic part and the second elastic part, the purposeof automatically adjusting the length of the coils in the loop is achieved, the coils in the loop cannot become larger and retreat due to the tension effect of a graft when no human external force exists, the operation time is shortened, and the operation risk is reduced. 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 method for manufacturing the loop. 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 w...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of ring and the manufacturing method of ring, 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 use Regression of the graft under the reaction force, which is not conducive to the operation
