摘要： An electrosurgical forceps includes 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. A movable handle actuates a drive assembly to move the jaw members relative to one another and at least one of the jaw members 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. The flexible boot includes a woven mesh-like base material that is covered with a layer of flexible silicone configured to reduce stray currents emanating from the jaw members and the pivot during electrical activation of the forceps.

摘要： An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members relative to one another 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 manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion. A second switch is disposed on the housing and is activatable to selectively deliver energy of a first electrical potential to one jaw member and selectively deliver energy of a second electrical potential to the other jaw member for treating tissue in a bipolar fashion.
