Embodiment 1

[0072] A production process of a surgical knife used by a doctor in a cardiac intensive care unit, the step 1 is to prepare a surgical knife base body 1;

[0073] In step 1, the preparation of the scalpel base 1 includes:

[0074] S1, raw material preparation, including the following raw material composition by weight,

[0075] 31 parts of zirconia;

[0076] 41 parts of alumina powder;

[0077] 9 parts of bitter earth;

[0078] 6 parts of zinc oxide;

[0079] 5 parts of yttrium oxide;

[0080] 3 servings of chitin.

[0081] Further, chitin, also known as chitin and chitin, is a polysaccharide substance extracted from the shells of marine crustaceans, and its chemical formula is (C8H13O5N)n. Chitin is light beige to white, soluble in concentrated hydrochloric acid, phosphoric acid, sulfuric acid and acetic acid, insoluble in alkali and other organic solvents, and insoluble in water. Chitosan, a deacetylated derivative of chitin, is insoluble in water and soluble in some ...

Abstract

The invention belongs to the technical field of surgical knives, in particular to a surgical knife for a doctor in a cardiac intensive care unit and a production process thereof. The surface of the fixed connection has anti-suction bumps. The surgical knife used by doctors in the cardiac intensive care unit and its production process are provided with a working part and a connecting part respectively by setting the surface of the base body of the scalpel. The preparation of zinc oxide, yttrium oxide and chitin reduces the production and preparation cost of the base of the scalpel, and improves the comprehensive performance of the scalpel, thus solving the problem that the existing high-performance scalpel needs to use high-performance metal or alloy materials, which leads to surgery. The cost of making knives remains high, especially for surgical knives used by doctors in the cardiac intensive care unit, which often use disposable scalpels, resulting in a higher cost of use.

Description

technical field [0001] The invention relates to the technical field of surgical knives, in particular to a surgical knife for doctors in a cardiac intensive care unit and a production process thereof. Background technique [0002] A scalpel is a commonly used medical instrument, especially a very important tool in medical surgery, which provides a strong guarantee for human health; a scalpel usually consists of a blade and a handle. The blade usually has a cutting edge and a mounting groove that is docked with the handle of the scalpel. The material is usually pure titanium, titanium alloy, stainless steel or carbon steel, which is generally disposable. During dissection, the blade is used to cut skin and muscle, the tip is used to clean blood vessels and nerves, and the handle is used for blunt dissection. Choose the appropriate type of blade and handle according to the size of the wound. Because the ordinary scalpel has the characteristics of "zero" damage to the tissue ...
