Abstract

The invention provides a medical arc-blade needle knife for treating tenosynovitis, and relates to the field of medical instruments. The medical arc-blade needle knife for treating tenosynovitis comprises a medical needle-knife holding end; a needle-knife mounting limiting ring is fixedly connected to the lower surface of the medical needle-knife holding end, and is coaxial with the medical needle-knife holding end; an embedded limiting groove is formed in the needle-knife mounting limiting ring in a mode of extending towards the front side face and the rear side face; the needle-knife mounting limiting ring is movably connected with a replaceable needle knife body through the embedded limiting groove. The holding end of the medical needle knife is subjected to curved surface modeling design, so that the medical needle knife is more in line with human body structure engineering; and thus, medical staff feel more comfortable when using and holding the arc-blade needle knife in cooperation with a rubber flexible gasket on the side face. Moreover, the replaceable needle knife body is arranged and can be reasonably replaced according to the body type of a patient as well as the operation site; and therefore, use flexibility of the medical arc-shaped needle knife is improved, and cleaning on the arc-shaped needle knife after use becomes more convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical arc-blade needle knife for treating tenosynovitis. Background technique [0002] The tendon sheath is the double-layer casing-like airtight synovial tube that covers the tendon, and is the synovial sheath that protects the tendon. It surrounds the tendon in two layers, and there is a cavity between the two layers, the synovial cavity, which contains the synovial fluid of the tendon sheath. The inner layer is closely attached to the tendon, and the outer layer is lined inside the tendon fiber sheath, and together with the bone surface, it has the functions of fixing, protecting and lubricating the tendon, preventing it from friction or compression. Long-term excessive friction of the tendon can cause injury and inflammation of the tendon and tendon sheath, causing swelling, which is called tenosynovitis. If left untreated, it may develop into permanent mobility...
