Insulating mechanically-interfaced adhesive for electrosurgical forceps

An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end movable about a pivot from a first position disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue. One or both of the jaw members are adapted to connect to a source of electrical energy such that the jaw members are capable of conducting electrical energy to tissue held therebetween. An flexible insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members and about the pivot. An adhesive is included and is operably disposed between at least one jaw member and the flexible insulating boot for securing the flexible insulating boot to the jaw member.
