Abstract:
1. A surgical tool handle, which comprises: a) a housing providing a linkage chamber extending from a proximal housing section comprising a grip end to a distal housing section comprising a tool end for receiving a tool; b) a tool linkage at least partially housed within the linkage chamber, the tool linkage comprising: c) wherein the handle lever is pivotable about the proximal housing pivot pin from a first, opened position spaced a maximum distance along a range of motion from the proximal housing section to a second, closed position spaced at a closer distance along the range of motion relative to the proximal housing section than the first position to thereby cause the main linkage, connected to the handle lever by the first free pivot pin, to move in a proximal direction toward the proximal housing section, to thereby cause the locking pawl, connected to the distal main linkage end by the second free pivot pin, to pivot with respect to the housing on the distal housing pivot pin from an open to a closed position, wherein the open position is configured to either receive a tool for attachment to the housing or release the tool from the housing and wherein the closed position is configured to detachably secure to a tool supported at the distal housing tool end, d) wherein the proximal housing section is aligned along an axis A-A, a radiused housing section extending distally from the proximal housing section curves about a focal point, and the radiused housing section extends distally to the distal housing section aligned along an axis B-B, and e) wherein an angle α measured between an axis C-C taken along the distal housing pivot pin with respect to the axis A-A of the proximal housing section is from about 30° to about 60°.
