Abstract
A surgical scalpel blade made safer by providing, on the front portion thereof, a blunted surface or tip which renders the point of the blade incapable of cutting, without impeding the ability of the blade to be drawn across the surface to be incised.
Claims8
A surgical scalpel blade defined by a sharpened first edge adapted to cut by drawing along a surface to be incised, a second edge opposite said first edge, a proximal end portion at a proximal end of said first edge and a proximal end of said second edge being adapted to accept a scalpel handle, and a distal end portion at which a distal end of said first edge and a distal end of said second edge meet at a juncture,
- a tip portion having a cross section greater than that of said blade being provided at said juncture, the greater cross section of said tip portion rendering said distal end of said first end incapable of cutting,
- said first edge of said blade having a belly portion extending further from said second edge than said tip portion, whereby the drawing of said blade is substantially unimpaired by said tip portion, said second edge being straight, said first edge curving from said belly portion toward said first edge at said distal end portion.
