Embodiment Construction

[0025] figure 1 A schematic diagram showing the structure of the folded suspension artificial ligament according to the present invention. Specifically, according to the folded suspension artificial ligament provided by the present invention, it includes the first pulling wire part 11, the first tibial tunnel braided part 21, the first intra-articular free fiber part 31, the femoral tunnel braided part 4, the second Two intra-articular free fiber parts 32, the second tibial tunnel weaving part 22, the second pull wire part 12, and a button plate with a ring. The folding and suspending artificial ligament is centrally symmetrical with respect to the midpoint of the braided part 4 of the femoral tunnel, and the button steel plate with a ring is connected to the midpoint of the braided part 4 of the femoral tunnel.

[0026] More specifically, the braided portion of the femoral tunnel 4 is bent into a U-shape at its midpoint. Preferably, the braided portion of the femoral tunnel ...

Abstract

The invention provides a foldable suspension-type artificial ligament, comprising a first traction line part (11), a first tibia tunnel weaving part (21), a first joint inner free fiber part (31), a thighbone tunnel weaving part (4), a second joint inner free fiber part (32), a second tibia tunnel weaving part (22) and a second traction line part (12). The beneficial effects of the invention are as follows: when artificial ligament is used for rebuilding human anterior cruciate ligament, the fixation of the artificial ligament is enhanced and the contact area of the artificial ligament and the bone tunnels is increased. Thus, the union of the artificial ligament and bone tunnels is promoted. In addition, the artificial ligament is simple in structure and convenient for 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 folded suspension artificial ligament and a preparation method thereof. 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 tibi...
