Abstract

A forceps includes an end effector assembly having first and second jaw members moveable with respect to one another between an open position and a closed position. A knife channel having a body and a base is defined within each jaw member. A knife assembly includes a knife having a bifurcated distal end. The bifurcated end includes first and second cutting members each defining an opposed cutting surface and having a tab at a free end thereof for translation through the base of a knife channel. The knife is translatable into the channels when the jaw members are in the closed position such that the cutting members are approximated when translated through the channels. The knife is also translatable into the channels when the jaw members are in the open position such that the cutting members are flexed apart when translated through the jaw members.
