Meniscus fixing device and meniscus fixing method

Abstract

The invention provides a meniscus fixing device and a meniscus fixing method, and relates to the technical field of medical instruments.The device comprises a first anchoring part and a second anchoring part, the tail end of the first anchoring part is provided with a mounting hole extending downwards, and the side wall of the first anchoring part is provided with an avoiding hole communicating with the interior of the mounting hole; and a barb structure with the tip facing the receding hole is arranged in the mounting hole. The second anchoring part is inserted into the mounting hole of the first anchoring part, and the outer wall of the second anchoring part and the inner wall of the mounting hole are used for clamping the root of the meniscus; and at least one part of the barb structure is located on the insertion path of the second anchoring part, so that the second anchoring part can push the tip end of the barb structure out of the avoiding hole. The root of the free meniscus is clamped and fixed through the inner wall and the outer wall of the first anchoring part and the inner wall and the outer wall of the second anchoring part, the second anchoring part can extrude the barb structure hidden in the first anchoring part out of the receding hole, the tip end of the barb structure is inserted into the hole wall of the planting hole, and the first anchoring part is fixedly connected with the bone.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a meniscus fixation device and a meniscus fixation method. Background technique [0002] At present, arthroscopic meniscus repair has been fully recognized clinically. Most meniscus repairs are based on meniscus tear, such as common inside-out, outside-in or all-in techniques, and relatively Mature. [0003] Before using the meniscus fixation device in the prior art, it is necessary to penetrate the tibia to obtain a through hole for installation, and fix it by means of sutures, anchors or sutures, and titanium plates. A large amount of bone loss, and the surgical procedure is more complicated. Contents of the invention [0004] The purpose of the present invention is to provide a meniscus fixation device and a meniscus fixation method to alleviate the technical problem that the existing meniscus fixation device needs to penetrate the tibia during installation, result...
