Insulating Mechanically-Interfaced Adhesive for Electrosurgical Forceps

摘要

An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof that are relatively 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. A movable handle is included that actuates a drive assembly to move the jaw members relative to one another. One or both of the jaw members includes one or more mechanical interfaces and is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. A flexible insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members and about the pivot. At least a portion of the flexible boot is configured to operatively engage the mechanical interface(s) on the jaw member. 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.
