ABSTRACT:
A detachable and replaceable end effector assembly. The detachable mechanism is made of standard end effectors attached to an actuating tip and pinned inside a yoke assembly. Replacement is made by pulling back a spring loaded radial lock 90, to disengage two rear tabs 51 on the outer tip 50. The yoke assembly is then rotated 90 degrees to disengage the rear yoke pin 9 from the tubular shaft 70. This rotation of 90 degrees also unlocks the T-bar 45 from the front "T" slot of the long actuator 80. The end effector or jaw assembly is then free to be pulled away from the remainder of the shaft. In addition there is a bayonet connection to hold the parts together and prevent accidental disconnection.
