Problems solved by technology
However, the hardness of nano ceramics is extremely high, although 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. Chipping is very easy to occur during the process, so the yield of traditional processing methods is very low, resulting in high prices for nano-ceramic scalpels

Embodiment 1
[0066] 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:
[0067] 1. Coarsely grind the two sides of the nano-ceramic scalpel and reduce the thickness to 0.8mm. .
[0068] 2. Roughly and finely ground the cutting edge of the nano-ceramic scalpel, one side is qualified.
[0069] 3. Turn over the rough and finely ground nano-ceramic scalpel edge, and the other side is qualified.
[0070] 4. Fine grinding and ultra-precision grinding of both sides of the nano-ceramic scalpel, reducing the thickness to 0.3mm.
[0071] 5. Polished nano-ceramic scalpel with blunt sharp edge.
[0072] 6. Testing and packaging.
[0073] The surface roughness and cutting edge radius of the nano-ceramic scalpel manufactured by the above-mentioned ELID grinding proces...

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 easy to corrode, passivate and have low service life during use and heating and disinfection; diamond scalpels The processing technology is complex, transparent, difficult to operate, and expensive. The nano-ceramic scalpel has a sharp edge, non-magnetic, non-toxic, non-static, Long service life, anti-corrosion, biocompatibility, high precision, fast healing of the incision edge, no obvious cut marks after operation, easy to operate It can be used at high temperature and can be reused many times without wear and tear, and the cost is moderate. In ophthalmology, plastic surgery, vascular surgery Surgery, microsurgery, neurosurgery, skin grafting and other fields have a wide range of application prospects. However...
