Abstract
Surgical instruments for insertion through trocar tubes are disclosed. The instruments broadly include: a hollow tube; a clevis which is formed separately from the tube with the distal end of the hollow tube crimped around the proximal end of the clevis, and with the clevis including a pivot pin; at least one end effector element having a pivot hole through which the pivot pin of the clevis is pivotally engaged, and another through-hole; a push rod extending at least partially through the hollow tube and mechanically coupled to the end effector element; and a plastic actuator engaging the proximal end of the push rod and for imparting reciprocal motion to the push rod relative to the tube, where the reciprocal motion is translated at the clevis into pivotal motion of the end effector element. Preferably, staple-like connectors are used to mechanically couple the end effector element to the push rod, especially for double acting instruments. The end effector elements are preferably formed of investment cast bronze.
