SILICON EDGES FOR SURGICAL AND NONSURGICAL APPLICATION

摘要

FIELD: medicine.;SUBSTANCE: invention concerns blades with rectilinear and curvilinear cutting edges, and to ways of their manufacturing. A blade is made of a plate from the crystalline material chosen from group, including crystalline silicon with selective orientation of crystals, silicon with orientation of crystals 110 and 111, silicon alloyed to certain specific resistance and content of oxygen, silicon nitride, processing of the first side of a plate from a crystalline material, performance in it of the first profile of a blade with chamfer, forming cutting edge of a blade, and close to it the second chamfer, and processing of the second side of the plate from a crystalline material, making of the second profile of a blade in it with passing along the first chamfer by the third chamfer of a cutting edge and the fourth chamfer close to the third chamfer, and a plate from a crystalline material is exposed to isotropic etching, obtaining a blade from it.;EFFECT: invention allows creating disposable blades in the conditions of the strict control of all technological process, as sharp as diamond blades, and as cheap, as stainless steel blades.;57 cl, 3 tbl, 73 dwg
