Embodiment Construction

[0020] figure 1 The schematic diagram showing the structure of the integrated annular suspension artificial ligament according to the present invention. Specifically, in this embodiment, the integrated annular suspension artificial ligament provided according to the present invention includes a ligament braided part 1 and a traction line 2, wherein the ligament braided part 1 is a closed loop structure, and the traction The thread 2 is connected to the braided ligament 1. The said ligament braided part 1 can be directly connected with an Endobutton steel plate (Endobutton), after being implanted in a human femoral tunnel, the connected Endobutton button steel plate can be clamped outside the femoral tunnel opening, which can suspend and fix the ligament .

[0021] Preferably, the opposite ends of the ligament braided part are U-shaped structures, and the middle parts between the opposite ends are close to each other. The integrated annular suspension artificial ligament is axi...

Abstract

The invention provides an integral annular suspension artificial ligament, which comprises a ligament woven part (1) and a traction line (2), wherein the ligament woven part (1) has an enclosed annular structure; and the traction line (2) is connected to the ligament woven part (1). The invention further provides a corresponding preparation method. The integral annular suspension artificial ligament has the beneficial effects that: fixation of the artificial ligament can be enhanced, and the contact area between the artificial ligament and a bone tunnel can be increased during reconstruction of a human anterior cruciate ligament by using the artificial ligament, so that healing of the artificial ligament and the bone tunnel is facilitated; and moreover, the integral annular suspension artificial ligament is simple in structure, and is convenient to use.

Description

Technical field [0001] The invention relates to an artificial ligament implanted in the human body, in particular to an artificial ligament connected with a button steel plate, in particular to an integrated annular suspension artificial ligament and a preparation method thereof. Background technique [0002] At present, the most mature artificial ligament in clinical applications 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 European CE certification and China SFDA certification. LARS artificial ligament is formed by winding and closing the polymer fiber mesh itself, which is divided into two bone tunnel parts, middle joint fiber parts and two ends traction line parts. When the LARS artificial ligament is implanted into the bone tunnel, a metal screw is used to compress and fix the femur and ...
