Abstract

The invention discloses a meniscus stitching instrument, and belongs to the technical field of meniscus stitching. The meniscus stitching instrument comprises a handle assembly, a needle tube assembly, and an implant, wherein a driving mechanism is arranged on the handle assembly; the needle tube assembly is mounted on the handle assembly; the needle tube assembly comprises an inner needle and anouter needle which sleeves the inner needle; the inner needle is connected with the driving mechanism so as to enable the inner needle to slide in the outer needle under the driving of the driving mechanism; the implant is placed in the outer needle before implantation; the implant comprises an implant body; the implant body is in a hollow cylinder shape; the middle section of the cylinder wall isprovided with a plurality of strip-shaped deformation strips; and the deformation strips are arranged in the length direction of the implant body. The meniscus stitching instrument further comprisesa stitching thread penetrating into the implant body; and the implant body is configured in a way that after the implant is pushed out of the outer needle by the inner needle, the stitching thread ispulled to enable the plurality of deformation strips to be opened in an umbrella shape so as to be tightly attached to the meniscus. The implant is pushed into the meniscus along with the outer needle; and after the implant is pushed out of the outer needle, the outer needle is pulled out and the stitching thread is pulled tightly to enable the implant body to be opened so as to be tightly attached to the meniscus.

Description

technical field [0001] The invention relates to the technical field of meniscus suturing, in particular to a meniscus suturing device. Background technique [0002] The meniscus is the semilunar cartilage located between the femur and tibia of the knee joint. Its edge is thicker and tightly connected with the joint capsule, and the center is thinner and free. A normal meniscus has the function of increasing the depression of the tibial condyle and lining the inner and outer femoral condyles, so as to increase the stability of the joint and play the role of cushioning and shock absorption. [0003] Meniscus injury is one of the common injuries in sports injuries, and it mostly occurs in people who exercise excessively and do heavy physical labor. The common meniscus injury is torn meniscus caused by torsion and external force, which is manifested as severe knee joint pain, joint swelling, exercise Due to limitations, meniscus suture is currently the most ideal surgical metho...
