Surgical knife

摘要

A surgical knife which is formed with air vent holes in the vicinity of the cutting edge of the blade to provide improved sharpness during the incision without the possibility of incised living tissue sticking to the blade surface and improved visibility of the incised surface or cut region. The surgical knife has a stem and a cutting edge, wherein one or a plurality of through-holes extending from the front to the back to serve as air vent holes during the incision of living tissue are formed in the vicinity of the cutting edge surface formed on the blade. The through-holes are not limited in shape to a circle; they may be oval or polygonal or in the form of slits or other elongated openings. They may also be a plurality of very small holes.
