ABSTRACT:
A modular surgical instrument includes a handle, an end effector, and an elongate tubular sleeve extending between and opposing the end effector and the handle, a reciprocating actuator rod disposed within the sleeve, the end effector being operably connected to a distal end of the actuator rod and having opposed members, at least one of which is movable with respect to another upon sliding movement of the actuator rod within the sleeve, and a handle including a pair of opposing actuating members, the handle having a first end connected to a proximal end of the tubular sleeve, and a second end releasably snap connected to a proximal end of the actuator rod. Compression of the actuating members toward each other causes the actuator rod to move at least one of the opposing members of the end effector with respect to the other. The disclosed arrangement allows an end effector to be easily removed from the handle and replaced with a different end effector, thus reducing costs associated with replacing worn end effectors and eliminating the need for providing each end effector with its own handle.
