Description

Novel meniscus full-internal stitching instrument

Technical Field

The utility model relates to the technical field of medical equipment, specifically a novel meniscus is sewing up ware entirely.

Background

The tibia articular surface has medial and lateral meniscus-shaped bones called meniscus, whose edge is thicker and tightly connected with the joint capsule, and central portion is thinner and free. In addition to the ability to repair itself after damage to the limbal portion, the meniscus is not self-repairing after rupture, and a fibro-cartilaginous, thin and narrow meniscus can be regenerated from the synovium after the meniscus has been removed. The normal meniscus has the effect of increasing tibial condyle depression and lining the medial and lateral femoral condyles to increase joint stability and cushion shock.

Meniscus injury is a common clinical disease, and the current suturing devices comprise MM2, FAST-FIX and the like of Schlerhui company, wherein MM2 is an outside-in suturing instrument, FAST-FIX is an all-in suturing device, but any suturing device is used for suturing the meniscus and a joint capsule together, so that the mechanical change of the meniscus is large, and local symptoms are common clinically. For meniscal injuries where damage to the red zone of the meniscus does not involve the joint capsule, there is an urgent need for a suturing device to suture the meniscus.
