31,740-00 TRANSMISSION LINK FOR USE IN SURGICAL INSTRUMENTS ABSTRACT A link (54), and assembly (12) and instrument (10) using same, for transmitting actuating forces from an actuating member (20) to a work member (52). The link (54) includes a link body (60) having a distal end and a proximal end. The distal end of the link body is movably interconnected with the work member (52) by a distal interconnection element such as an arcuate groove-and-flange assembly (62, 80), and is inter- connected at its proximal end to the actuating member (20) by a proximal pivotal interconnection element (64, 65). The proximal element (64, 65) transmits a first actuating force (118) from the actuating member (20) to the work member (52). A shoulder (66), disposed on the link body (60) preferably between the distal and proximal elements for interconnecting, engages the actuating member (20) when a second, greater actuating force (124) is applied to the actuating member in a direction opposite to that of the first actuating force. The greater force (124) is thereby transmitted fully to the work member (52). The link assembly (12) preferably includes a spacer member (90) to assist positioning of the actuating member.
