Patent ID: 8657833

Claim:
A surgical tool handle, which comprises: a) a housing providing a linkage chamber extending from a proximal housing section providing a grip end to an intermediate angled housing region connected to a distal housing neck section providing a tool end for receiving a tool, wherein the proximal housing section is aligned along a longitudinal A-A and the angled housing region extends along an axis B-B; b) a tool linkage at least partially housed within the linkage chamber, the tool linkage comprising: i) a handle lever attached to the housing by a proximal housing pivot pin to thereby provide a first pivotable connection between the tool linkage and the housing; ii) a locking pawl attached to the housing by a distal housing pivot pin to thereby provide a second pivotable connection between the tool linkage and the housing; iii) an inverted linkage comprising a proximal inverted linkage end and a distal inverted linkage end connected by a first free pivot pin to the handle lever to thereby provide a third pivotable connection; and iv) a main linkage comprising a proximal main linkage end connected by a second free pivot pin to the proximal inverted linkage end adjacent to the proximal housing section in a fourth pivotable connection and a distal main linkage end connected by a third free pivot pin to the locking pawl adjacent to the distal housing section in a fifth pivotable connection, v) wherein the locking pawl is disposed within the distal housing neck section having a longitudinal axis C-C that is parallel to, but spaced from, the axis A-A; and 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 inverted linkage, connected to the handle lever by the first free pivot pin, to move in a proximal direction to thereby move the main linkage, connected to the inverted linkage at the second free pivot pin, in a proximal direction toward the proximal housing section, to thereby cause the locking pawl, connected to the distal main linkage end by the third free pivot pin, to pivot with respect to the housing on the distal housing pivot pin from an open configuration ready to receive a tool for attachment to the housing to a closed configuration detachably secured to a tool supported at the distal housing tool end.
