Abstract
A reconfigurable surgical apparatus that includes a surgical instrument assembly that is formed with a hollow manipulation shaft. A linearly or rotationally movable prime mover is received within the shaft and is activated by an actuator located at a proximal end. A coupler is formed about a distal end of the shaft to have a capture ledge that is configured to releasably engage an interchangeable surgical tool that is formed with an anchor adapted to releasably mate to the capture ledge. The coupler may optionally incorporate a frangible portion that severs a portion of the coupler when the interchangeable surgical tool is removed from the apparatus to ensure single use operation of the tool. The apparatus may also have a predetermined mode of failure ensuring a known point of failure upon exposure to a predetermined force. The apparatus may also be partially enclosed by a shroud.
