Double-bundle artificial ligament and manufacturing method, implanting device and implanting method thereof

Abstract

The invention provides a double-bundle artificial ligament and a manufacturing method, an implanting device and an implanting method thereof. The double-bundle artificial ligament comprises a flexible long-strip-shaped body. The long-strip-shaped body comprises a first body segment, a second body segment and a third body segment. The manufacturing method includes the steps that a lateral plate is woven; the lateral plate is cut, and a fold line is set; a first pull wire and a second pull wire are threaded from one side of the fold line to the other side of the fold line; corners are cut; the lateral plate is wound to the fold line from the two sides to form a cylinder; the first pull wire and the second pull wire are tensioned; a wire is wound around the two ends of the long-strip-shaped body. The implanting device comprises a hanging assembly and a fixing assembly. The implanting method includes the steps that the third body segment is arranged on the hanging assembly in a penetrating mode; the hanging assembly is fixed; the first body segment and the second body segment are fixed. According to the double-bundle artificial ligament and the manufacturing method, the implanting device and the implanting method thereof, the problems that knee joint stability can not be recovered, and donor site insufficiency, donor site complications, allograft ligament formation time delay and immunological rejection occur in reconstruction of an anterior cruciate ligament are solved, the reconstruction effect is greatly improved, and the adaptability is high.

Description

Technical field [0001] The invention relates to the technical field of medical device design for ligament reconstruction, in particular to a double-bundle artificial ligament and a manufacturing method, an implanting device and an implanting method. Background technique [0002] Anterior cruciate ligament (Anteriorcruciateligament, hereinafter referred to as ACL) is one of the important structures to maintain the stability of the knee joint. The stability of the knee joint includes anteroposterior stability, varus stability, and rotational stability. Natural anatomy shows that ACL contains two separate bundles, which are called anteromedial (hereinafter referred to as AM) bundles and posterolateral (hereinafter referred to as PL) bundles according to their stop points on the tibial footprint. AM and PL differ in width, length, and insertion area. Among them, AM is anterior and inner at the tibial stop point, and is upper and posterior at the femoral stop point; AM is tense durin...

AI Technical Summary

Problems solved by technology

[0005] However, since the existing double-bundle reconstruction grafts are limited to autologous and allograft ligaments, there are also tissue defects such as autografts that may cause tissue defects at the sampling site, and the supply of human tissue is limited; at the same time, allografts have rejection reactions, quality control Difficulty, risk of spreading diseases, long adaptation time, etc.
