Abstract

A surgical drill chuck comprising a main body of elongated cylindrical construction having intersecting main body end and main body side surfaces. A plurality of movable jaws of elongated cylindrical construction carried by the main body having intersecting jaw end and jaw side surfaces. A sleeve of elongated cylindrical construction carried circumferentially on the main body being operatively associated with the jaws for extending and retracting the jaws when the sleeve is rotated. The sleeve having intersecting sleeve end and sleeve side surfaces. Radiused corners provided at the intersection of the main body end and main body side surfaces, jaw end and jaw side surfaces, and sleeve end and sleeve side surfaces so that a surgical drill chuck is provided with no sharp edges to prevent snagging, tearing or puncturing surgical latex gloves while handling the chuck during surgical operations.

Dependent claims

A surgical drill chuck comprising:

a main body of elongated cylindrical construction having a first distal end and a second distal end;
said first distal end having a first radiused body corner interconnecting a front end surface and a circumferential side surface, and said second distal end having a second radisued body corner interconnecting a rear end surface to said circumferential side surface so that said first and second distal ends are rounded to prevent damage to a surgical latex glove;
a plurality of movable jaws carried by said main body having a projecting end for extending outward from said front end surface of said main body;
said projecting end including a radiused jaw corner interconnecting a jaw end surface and a jaw side surface so that said projecting end is rounded to prevent damage to surgical latex glove;
a sleeve rotatably carried on said circumferential side surface of said main body operatively associated with said jaws for extending and retracting said jaws when said sleeve is rotated, said sleeve having a plurality of gear teeth circumferentially spaced around a first sleeve end for cooperating with a chuck key to rotate said sleeve;
each of said gear teeth including an outer tooth surface having a first tooth surface extending generally in a radial manner outward from said circumferential side surface of said main body, and a radiused tooth corner interconnecting said first tooth surface to a circumferential sleeve side surface so that the outer surfaces of said gear teeth are rounded to prevent damage to a surgical latex glove;
and
said main body, jaws, and sleeve being finished to provide dull rounded edges at the intersections of adjacent surfaces;
whereby a surgical drill chuck is provided with smooth rounded surfaces and edges to prevent snagging, tearing or puncturing surgical latex gloves while handling the chuck during surgical operations.
