Abstract

The invention provides bioceramic operation scissors and an application thereof. The bioceramic operation scissors include a first shear part, a second shear part and a first rotating shaft; the first shear part includes a first scissors arm and a first finger ring; the second shear part includes a second scissors arm and a second finger ring; the first scissors arm and the second scissors arm both can be mounted on the first rotating shaft in a rotating manner; the first finger ring and the second finger ring are respectively arranged on the first scissors arm and the second scissors arm, and are respectively provided with a first finger-tapping hole and a second finger-tapping hole; one side, close to the first finger ring and located on the first rotating shaft, on the first shear part is provided with a hexagonal pattern; the first shear part (1) and the second shear part (2) are made of bioceramic materials. The bioceramic operation scissors have the advantages of convenience in use, and good biocompatibility and anti-slip effect, do not affect nuclear magnetic resonance imaging, and can be applied to the technical field of intraoperative nuclear magnetic resonance.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to bioceramic surgical scissors and its application. Background technique [0002] With the development of science and technology, medical technology continues to improve, and there are more and more medical devices. Different medical devices can effectively facilitate different operations for doctors, but it also means that doctors have to constantly replace devices, such as surgical scissors. In the process, substances such as fat may adhere to the surgical scissors, which may cause the surgical scissors to slip during the process of replacing the instruments. Moreover, most of the current surgical scissors are not light enough, and the replacement of instruments will seriously delay the operation time. [0003] Bioceramic materials are a new field of material industry development. Bioceramics refers to a class of ceramic materials used for specific biological or physi...
