Abstract

The invention discloses a hinge block meniscus stitching instrument, and belongs to the technical field of meniscus stitching devices. The hinge block meniscus stitching instrument includes a handle assembly, a needle tubing assembly and an implant, wherein a drive mechanism is arranged on the handle assembly, the needle tubing assembly is mounted on the handle assembly, and an inner needle is connected with the drive mechanism so that the inner needle is driven by the drive mechanism to slide inside an outer needle; the implant includes an hinge plate, a hinge rotating shaft and at least twocheck blocks, the check blocks are arranged on the hinge rotating shaft, and are put in the outer needle in a closed shape, and stitching threads are wound around the check blocks; and the check blocks have the arrangement that after the implant is pushed by the inner needle out of the outer needle, the check blocks are opened under the pull action of the stitching threads, or stretch by itself, so that the check blocks are attached to a meniscus. After the implant is pushed out, the check blocks can be stuck on the meniscus, so that implantation is completed.

Description

technical field [0001] The invention relates to the technical field of meniscal suturing devices, in particular to a meniscal suturing device with a hinge block. 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 th...
