An electrosurgical forceps includes first and second shaft members pivotably coupled to one another via a pivot member such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A knife is translatable between retracted and extended positions. A knife deployment mechanism is operably coupled to the first shaft member and includes at least one trigger and at least one linkage coupling the at least one trigger with the knife such that pivoting of the at least one trigger relative to the first shaft member translates the knife between the retracted and extended positions. A knife lockout biased towards a locked position inhibits distal translation of the knife. The knife lockout is movable from the locked position to an unlocked position upon approximation of the jaw members to permit distal translation of the knife.

Electrosurgical forceps for grasping, treating, and/or dividing tissue

A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.
