ABSTRACT:
An instrument (602), particularly suited for endoscopic use, has an elongate body, including a base (604) and an elongate spindle (630) rotatably mounted to the base. A removable end-effector assembly (612), mounted at the distal end of the spindle (630), includes end-effector elements (608, 610), such as a pair of jaws, actuated by finger and thumb rings (616, 618) mounted to the base. A rotary actuator trigger (78) is slidably mounted to the base. The spindle (630) has a spiral groove (632) engaged by a cam pin (82) extending from the trigger so that axial movement of the trigger causes rotary motion of the spindle and the end-effector assembly therewith. The spindle and end-effector assembly are sheathed by a nonrotating sleeve (688) with an unbroken outer surface. The sleeve can be releasably translated axially to release or engage an end-effector assembly, allowing use of alternate end-effector assemblies.
