Abstract

The invention discloses a scalpel blade and a preparation method of the scalpel blade. The scalpel blade is prepared from the following raw material in parts by weight: 78-80 parts of cubic boron nitride, 50-52 parts of cubic zirconia, 38-40 parts of strontium titanate, 6-8 parts of tungsten carbide, 10-12 parts of aluminum oxide, 1-3 parts of iron sesquioxide, 2-4 parts of silicon nitride, 6-8 parts of zirconium nitride, 2-4 parts of molybdenum disilicide, 4-6 parts of tantalum carbide, 2-4 parts of titanium nitride, 12-14 parts of titanium dioxide, 10-12 parts of polymerized rosin, 8-10 parts of copal resin, 6-8 parts of graphite powder, 1-3 parts of samarium oxide, 1-3 parts of nickel oxide, 15-17 parts of quartz sand, 1-3 parts of zinc oxide and 17-19 parts of silver paste. The scalpel blade has high strength.

Description

technical field [0001] The invention relates to a scalpel blade and a preparation method thereof. Background technique [0002] Surgery refers to the treatment such as excision, suture and other treatment performed by doctors on the patient's body with medical equipment. The operation performed on the human body with knives, scissors, needles and other instruments to maintain the health of patients. It is the main treatment method of surgery, commonly known as "surgery". The purpose is to treat or diagnose diseases, such as removing diseased tissue, repairing damage, transplanting organs, improving the function and shape of the body, etc. Early operations were limited to simple manual methods of cutting, cutting, and suturing on the body surface, such as abscess drainage, tumor resection, and trauma suture. Therefore, surgery is an operation that destroys the integrity of tissue (incision) or restores tissue whose integrity has been compromised (suturing). With the devel...
