Problems solved by technology

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

Embodiment Construction

[0025] Please refer to the accompanying drawings, which are shown in order to illustrate a preferred embodiment of the present invention, rather than to limit the same embodiment. Such as figure 1 As shown, the first embodiment of the present invention is a stainless steel scalpel 20 having a proximal end 21, a distal end 22, a leading or anterior end 23, and a Trailing or posterior end 24 . The scalpel 20 is provided with an abrasive trailing surface 25 which occupies most of the half of the distal end 22 of the blade behind the leading end 23 . The ground trailing edge surface 25 is formed by grinding or blasting the blade with another abrasive, such as alumina or ceramic alumina. The ground surface can also be formed by build-up, where grit made of steel or composite material is bonded and then sintered to the blade. The abrasive surface may contain a plurality of peaks or valleys or both. They may consist of conical, pyramidal or spherical protrusions and may be unifo...

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.

Description

[0001] Cross-referenced related application documents [0002] US Provisional Application No. 61 / 693,453, filed August 28, 2012, the contents of which are incorporated herein by reference. 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...
