Patent ID: RE44834

Claim:
An electrosurgical forceps, comprising: a shaft having a pair of jaw members at a distal end thereof, the jaw members being movable about a pivot from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue, the shaft defining a longitudinal axis therethrough; a movable handle that actuates a drive assembly to move the jaw members relative to one another; at least one of the jaw members including a tissue-engaging surface adapted to connect to a source of electrical energy such that the at least one jaw member is capable of conducting energy to tissue held therebetween; and a flexible insulating boot mounted over the pivot, the flexible insulating boot having a proximal portion disposed on a portion of the shaft and a distal portion disposed on a portion of an exterior surface of the pair of jaw members proximal to the tissue-engaging surface of the at least one jaw member, the proximal portion and the distal portion of the flexible insulating boot disposed such that the flexible insulating boot remains in a substantially stationary position relative to the longitudinal axis and with respect to a reciprocating sleeve of the drive assembly and the jaw members when the drive assembly mechanically advances the reciprocating sleeve to apply a predetermined closure force between the jaw members.
