Hollow tubular band-shaped foldable suspension artificial ligament

Abstract

The invention provides a hollow tubular banded foldable suspension type artificial ligament. The hollow tubular banded foldable suspension type artificial ligament comprises a first traction line portion (11), a first tibia tunnel weaving portion (21), a first intra-articular free fiber portion (31), a first femur tunnel weaving portion (41), a third intra-articular free fiber portion (5), a second femur tunnel weaving portion (42), a second intra-articular free fiber portion (32), a second tibia tunnel weaving portion (22) and a second traction line portion (12). The hollow tubular banded foldable suspension type artificial ligament has the advantages that when the artificial ligament is used for reconstructing a human anterior cruciate ligament, fixation strength of the artificial ligament is enhanced, contact area of the artificial ligament with bone tunnels is increased, and the banded ligament can be filled with tendon or sclerotin so as to promote healing of the artificial ligament and the bone tunnels; the artificial ligament is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to an artificial ligament implanted into a human body, in particular to an artificial ligament connected with a button steel plate, in particular to a foldable suspension type artificial ligament in the shape of a hollow tube. Background technique [0002] At present, the most mature artificial ligament in the world is the French LARS artificial ligament, which is made of high-toughness polyethylene terephthalate (PET). It began to be used clinically in 1994, and was successfully used in China for the first time in 2004. It has passed the European CE certification and the Chinese SFDA certification. The LARS artificial ligament is formed by winding and closing the polymer fiber net itself, and is divided into bone tunnel parts on both sides, joint fiber parts in the middle and traction wire parts at both ends. When the LARS artificial ligament is implanted in the bone tunnel, a metal screw is pressed and fixed in the femoral and ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects that the LARS artificial ligament is unfavorable to the healing of the ligament and the bone tract and the fixation method is not good in the prior art, the purpose of the present invention is to provide a hollow tubular strip-shaped foldable suspension artificial ligament and its preparation method
