Abstract
An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end and movable about a pivot from a first position and disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue, a movable handle that actuates a drive assembly to move the jaw members relative to one another. At least one jaw member conducts electrical energy to tissue held therebetween. A flexible insulating boot is disposed on an exterior surface of at least one jaw member and about the pivot, and includes a first longitudinal portion made from a high durometer material and a second longitudinal portion made from a low durometer material. The high durometer material may operably retain the flexible insulating boot atop the proximal ends of the jaw members.
