Abstract

The invention discloses a material for surgical instruments. The material comprises the following chemical components in percentages by weight: 0.30-0.40% of C, less than or equal to 1.0% of Si, less than or equal to 1.0% of Mn, 14-16% of Cr and the balance of Mo, V and Fe. By virtue of the mode, the invention provides the material for the surgical instruments and a preparation method of a steel strip of the material. Mo and V are added in the material, so that the toughness and corrosion resistance of the material are improved, the grain structure is refined, the quenching performance of heat treatment is improved, the mechanical property of the material is improved, and the surgical safety is guaranteed.

Description

Technical field[0001]The present invention relates to the field of surgical instruments, and more particularly to an surgical instrument material and a method of preparing thereof.Background technique[0002]Surgery instruments refer to medical devices used in clinical surgery, with expansion of surgery, surgical instruments are also increasing, improved, and updated, but commonly used nothing is not adjacent, needles, needles, pliers, hooks, etc. class.[0003]A good surgical instrument use and maintenance can use ten years, extend the life of the surgical instrument, and the treatment of the treatment and use before use, it is necessary to properly, some local surgery is more, for the sterilization time of the surgical instrument The problem is difficult to wait, usually use plasma sterilization, enabling the corrosion, using several discovery of large-area rust, resulting in the devices to be replaced.[0004]During the operation, blood or tissue contamination should be properly wiped,...
