Abstract

A nano-ceramic scalpel is free of magnetism and static electricity, long in service life and high in precision. The biocompatibility with human tissue is good, acidemia infiltration can be avoided, disinfection can be achieved easily, no stimulation and antibody responses exist, wound infection by metal diffusate cannot happen, incisions can be healed quickly, no obvious scars are left after operations, and the nano-ceramic scalpel is particularly suitable for the microsurgery, plastic surgery and the like. However, nano ceramic is extremely high in hardness and low in toughness, and thus manufacturing and processing are quite difficult. The invention provides an ELID sharpening technology and equipment which are used for manufacturing the nano-ceramic scalpel. According to the nano-ceramic scalpel as shown in Figure 1, the ELID sharpening technology and the self-designed process equipment are used for successfully grinding the two side faces of the nano-ceramic scalpel, the surface roughness reaches 6nm, and the cutting edge radius of the nano-ceramic scalpel reaches 200nm. The manufactured nano-ceramic scalpel is high in wound healing speed, free of obvious scars after healing and good in effect in clinical incision experiments of laboratory rats.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment. In particular, it relates to a sharpening technology and equipment for a nano-ceramic scalpel. Background technique

[0002] Traditional steel disposable scalpels are prone to corrosion, passivation, and low lifespan during use and heating and disinfection; diamond scalpels are complex in processing technology, transparent, difficult to operate, and expensive. The nano-ceramic scalpel has a sharp edge, non-magnetic, non-toxic, non-static, long life, anti-corrosion, biocompatibility, high precision, fast healing of the knife edge, no obvious cut marks after operation, easy to operate, and can be used at high temperature It can be used under the environment, and can be reused many times, never wears out, and the cost is moderate. It has wide application prospects in ophthalmology, plastic surgery, vascular surgery, microsurgery, neurosurgery, skin grafting and other fields. However, th...
