Abstract

The invention relates to a device for meniscus suture. The device comprises a front gun handle, a rear gun handle, a needle core and a duckbill clamp, wherein the front handle and the rear handle aremovably connected into a handle structure of a pistol, a movement guide mechanism and an elastic reset mechanism are arranged between the front handle and the rear handle, the movement guide mechanismis used for guiding the rear handle to move towards the front handle when a holding force is applied, and the elastic reset mechanism is used for driving the rear handle to make reset motion when theholding force is released; the needle core mainly consists of a needle base, a needle rod and a puncture needle which are connected in sequence, the needle base is connected with a rear gun handle, and the puncture needle is positioned on one side, which is far away from the rear gun handle, of the front gun handle; and the duckbill clamp is positioned on one side, which is far away from the rearhandle, of the front handle and is used for clamping the tissue to be sutured, the duckbill clamp comprises an upper clamping plate and a lower clamping plate, a puncture needle passage through whicha puncture needle passes is arranged in the lower clamping plate, and a puncture needle through hole through which the puncture needle passes is formed in the upper clamping plate. The device has theadvantages of convenient operation, safety, simplicity, low price and high suture efficiency.

Description

technical field [0001] The invention belongs to the technical field of meniscus suturing, and relates to a device for meniscus suturing. Background technique [0002] Meniscus injury is one of the common sports injuries, most of which are caused by torsional force. Severe knee joint pain, inability to straighten automatically, joint swelling, and tenderness in the joint space are important criteria for judging meniscus injury. Since arthroscopic surgery was carried out in the early years, the meniscus has been subtotal or total removed to relieve symptoms. However, in view of the possibility of mechanical disorder of the knee joint, cartilage degeneration and other complications after resection, it will eventually lead to the occurrence of osteoarthritis. [0003] With the in-depth study of meniscus anatomy, physiological function and post-injury repair mechanism, especially the rapid development and popularization of arthroscopic technology, people began to pay attention t...
