However, the hardness of nano-ceramics is extremely high. Although the toughness is much higher than that of ordinary ceramics, compared with the Cr6 material of ordinary scalpels, the toughness is still very low, and it is easy to cause chipping when grinding the cutting edge. Therefore, the yield of traditional processing methods Very low, resulting in a high price of nano-ceramic scalpels

Embodiment 1
[0067] The above-mentioned ELID grinding process and equipment for manufacturing nano-ceramic scalpels is a typical and commonly used method. During specific implementation, some processes can be combined to improve efficiency and save man-hours. The following process flow is for reference:
[0068] 1. Coarsely grind the two sides of the nano-ceramic scalpel and reduce the thickness to 0.8mm. .
[0069] 2. Roughly and finely ground the cutting edge of the nano-ceramic scalpel, one side is qualified.
[0070] 3. Turn over the rough and finely ground nano-ceramic scalpel edge, and the other side is qualified.
[0071] 4. Fine grinding and ultra-precision grinding of both sides of the nano-ceramic scalpel, reducing the thickness to 0.3mm.
[0072] 5. Polished nano-ceramic scalpel with blunt sharp edge.
[0073] 6. Testing and packing.
[0074] The surface roughness and cutting edge radius of the nano-ceramic scalpel manufactured by the above-mentioned ELID grinding process ...

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...
