Abstract
The invention relates to a target knife utilizing laser surface texture optimization. The target knife comprises a stainless steel target knife body. The surface of the target knife body is provided with optimized surface tissue obtained through laser phase transformation hardening or laser remelting, the superfine hardening tissue is obtained on the surface of the knife body, the knife body surface abrasion resistance and high temperature oxidation resistance are improved, and friction between the knife body and the human tissue is reduced. The stainless steel surface tissue optimization is achieved through laser phase changing hardening or laser remelting, the content is not changed, after laser surface texture hardening, the corrosion resistance, abrasion resistance and high temperature oxidation resistance of the stainless steel knife body surface are remarkably improved, when the knife body enters the human body and is pulled out from organ tissue, friction between the knife body and the human tissue is reduced, and a knife edge becomes smaller, and therefore pain of a patient is relieved.
