1. An electrosurgical forceps, comprising:
first and second shaft members each including an inner frame and a jaw member secured to and extending distally from the inner frame, the jaw member of the first shaft member including a jaw support engaged with the inner frame of the first shaft member;
an insulative housing surrounding a portion of the jaw support and extending proximally about a portion of the inner frame of the first shaft member;
a pivot member pivotably coupling the inner frames of the first and second shaft members to one another such that pivoting of the first and second shaft members relative to one another between spaced-apart and approximated positions pivots the jaw members relative to one another between open and closed positions;
a knife selectively translatable through the first shaft member from a retracted position to an extended position wherein the knife extends at least partially between the jaw members; and
a knife deployment mechanism operably coupled to the first shaft member, the knife deployment mechanism configured to translate the knife between the retracted and extended positions, wherein the knife deployment mechanism is coupled to the knife by a pivot pin extending through the knife, the pivot pin disposed within a longitudinal slot defined through the inner frame of the first shaft member such that the pivot pin translates through the longitudinal slot during translation of the knife between the retracted and extended positions.
