Abstract

The invention discloses a meniscus stitching instrument. The meniscus stitching instrument comprises a handle, a propelling device on the handle, a needle rod, and at least one implant fixing piece atthe head end of the needle rod, wherein the propelling device is used for driving the implant fixing pieces to do propelling motion forwards in the needle rod; the implant fixing pieces are in an X shape; the surfaces of the implant fixing pieces are further provided with a plurality of punctures. According to the meniscus stitching instrument, puncturing and fixing of multiple positions can be achieved one time, the operation efficiency is greatly improved, and the operation time is saved. Besides, due to the design of the X-shaped implant fixing pieces, the fixing strength of the implant fixing pieces is obviously improved, and the safety and the effectiveness of an operation are ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a meniscus stapler. Background technique [0002] As we all know, the meniscus is a semilunar cartilage-like tissue located between the femur and tibia of the knee joint, and is located on the medial and lateral articular surfaces of the tibial plateau. The cross-section of the meniscus is triangular, thick on the outside and thin on the inside, slightly concave on the top to fit the femoral condyle, and flat on the bottom to meet the tibial plateau. The meniscus has the functions of increasing stability, transmitting load, absorbing shock, and lubricating joints. With the improvement of people's living standards, sports injuries are also increasing day by day, and meniscus injuries are more and more common. [0003] There are three types of meniscus suture methods: Outside-in, Inside-out and All-inside. Depending on the suture method, there will be corresponding su...
