Improved scalpel

Abstract

A scalpel for cutting soft tissues of the body with an abrasive trailing surface. The abrasive trailing surface reduces distinct scar formation by supporting wound healing. The scalpel can be mounted upon a traditional handle. It may also be implemented as a reciprocating saw, as a rotary drill and reciprocating saw, or as a circular and reciprocating saw.

Background technique [0003] The medical industry in the United States uses tens of millions of scalpels every year. Most are made of high grade stainless steel and use traditional handles. In more than a century, the stainless steel scalpel has changed very little in form, function, or effectiveness. Other types of cutting devices, such as laser and plasma beams, electric current cutting tools, ultrasonic knives, cryogenic knives, and high-velocity water jets have been achieved with varying degrees of success. However, the hand-held stainless steel scalpel remains the most commonly used cutting tool. Unfortunately, stainless steel scalpels produce unsatisfactory cosmetic results for two reasons: significant scar formation and beveled, curved incisions. [0004] Visible scarring becaus...

As a result, the cutting edge tends to "skid" as it is drawn around an acute angle, resulting in uneven and over-cutting, which in turn results in a larger scar
