Abstract
A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion. A pin extends through the first slot, the second slot, and the third slot to prevent deployment of the rod when the pin is in the locking portion and to permit deployment of the rod when the pin is in the guide track portion. A first actuator produces relative movement of the first and second shafts to move the jaws relative to each other and move the pin from the locking portion to the guide track portion of the third slot. A second actuator produces movement of the rod to deploy the rod when the pin is in the guide track portion.
