Claim:
A modular endoscopic surgical device, comprising: an insertion device having a cartridge movably disposed on a distal portion thereof, the cartridge having a plurality of chambers formed therein; a plurality of surgical end effectors, each surgical end effector being disposed within a chamber in the cartridge; and an instrument shaft adapted to interchangeably mate with the plurality of surgical end effectors, the instrument shaft having a first member adapted to selectively engage a surgical end effector disposed within a chamber, and a second member, the first member being adapted to translate relative to the second member to displace said surgical end effector from the chamber, wherein each end effector is movable within the chamber between a first position in which at least one pin on the end effector extends into at least one bore formed in the chamber to retain the end effector in the chamber, and a second position in which the at least one pin on the end effector is retracted into the end effector to allow the end effector to be released from the chamber.
