specific Embodiment approach 1

[0022] Embodiment 1: In this embodiment, the medical degradable magnesium alloy meniscus suture is composed of a degradable magnesium alloy and a degradable drug-loaded coating.

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment differs from Embodiment 1 in that the degradable magnesium alloy is composed of Mg-Ca alloy, Mg-Sn-Mn alloy or Mg-Sn-Mn-Zn alloy. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment is different from Embodiment 1 in that the degradable drug-loaded coating is polylactic acid-glycolic acid copolymer or modified chitosan. Others are the same as in the first embodiment.

Abstract

The invention provides a medical degradable magnesium alloy meniscus suture line, and relates to a meniscus suture line, aiming at solving the technical problems such as high brittleness and limited length when a catgut line is taken as a suture line. The medical degradable magnesium alloy meniscus suture line consists of a degradable magnesium alloy suture line and a degradable medicine-carried coating layer. The meniscus suture line provided by the invention is high in hardness, and unlimited in length, and the suture line is degradable per se after a meniscus is healed, so that the healed meniscus can play the physiological function more perfectly.

Description

technical field [0001] The invention relates to a meniscus suture. Background technique [0002] The meniscus is an important organ in the knee joint. Its damage or incompleteness will have a major impact on the knee joint and it is very important to restore its full shape. Arthroscopic meniscus suturing is the only way to restore the integrity of the meniscus. Suture repair of the meniscus can restore the anatomical shape and important physiological functions of the meniscus, and avoiding the occurrence of knee osteoarthritis is an ideal surgical method for the treatment of meniscus injuries. At present, meniscus sutures are often ligated and fixed through the joint capsule. The meniscus and joint capsule are integrated with non-absorbable sutures, which limits the physiological movement of the meniscus, and some patients also experience joint snapping. [0003] Biodegradable materials refer to materials that, after being implanted into organisms, are degraded and hydroly...
