Problems solved by technology

[0003] Aiming at the defects that the LARS artificial ligament is not conducive 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 single-hole suspension type artificial ligament and its preparation method. The artificial ligament provided by the present invention It can not only connect the button plate to increase the firmness of the fixation, but also increase the contact area between the artificial ligament and the bone tunnel, thereby promoting the healing of the ligament and the bone tunnel

Embodiment Construction

[0028] figure 1 A schematic structural view of the single-hole suspension artificial ligament according to the first embodiment of the present invention is shown. Specifically, in this embodiment, the single-hole suspension artificial ligament provided by the present invention includes a femoral tunnel part 1, an intra-articular free fiber part 2, a tibial tunnel braided part 3, and a pull wire part 4 connected in sequence, Wherein, a single hole 9 is provided on the femoral tunnel part 1 . The femoral tunnel part 1 is composed of a femoral tunnel braided part. The single hole 9 can be directly connected with a button plate (Endobutton) with a ring. After being implanted in the human femoral tunnel, the connected Endobutton button plate can be pressed outside the opening of the femoral tunnel to suspend and fix the ligament.

[0029] In a preferred example of this embodiment, in the long axis direction, the length of the braided part of the femoral tunnel is 25 mm, and the d...

Abstract

The invention provides a single-hole suspended artificial ligament which comprises a femoral tunnel part, an intra-articular free fiber part, a tibial tunnel weaving part and a pull wire part that are sequentially connected, wherein a signal hole is formed on the femoral tunnel part. The invention further provides a preparation method of the single-hole suspended artificial ligament. The single-hole suspended artificial ligament has the benefits that when the artificial ligament is used to reconstruct a human anterior cruciate ligament, the fixation of the artificial ligament is intensified, and a contact area between the artificial ligament and a bone tunnel is increased, thereby promoting the healing of the artificial ligament and the bone tunnel; and 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 single-hole 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...
