An endoscopic forceps, comprising: a housing having a shaft attached thereto, the shaft including a pair of jaw members (110, 120) disposed at a distal end thereof; a drive assembly disposed in the housing operable to move 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 (30a, 30b) operatively connected to the drive assembly, the handles being movable relative to the housing to actuate the drive assembly to move the jaw members; each jaw member adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue; and a switch (250, 260) disposed on the housing and being activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue, the switch being operatively coupled to an intensity control mechanism disposed within the housing, which is selectively adjustable to regulate the level of electrosurgical energy to at least one jaw member, the intensity control mechanism includes a first mechanical interface configured to engage a series of corresponding mechanical interfaces defined in the housing to regulate the level of electrosurgical energy in discreet increments, the first mechanical interface includes a detent and the corresponding mechanical interfaces defined within the housing include recesses (163a', 163b', 163c', 163d', 163e'), wherein the detent is disposed in a cantilevered fashion atop the intensity control mechanism. a housing having a shaft attached thereto, the shaft including a pair of jaw members (110, 120) disposed at a distal end thereof; a drive assembly disposed in the housing operable to move 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 (30a, 30b) operatively connected to the drive assembly, the handles being movable relative to the housing to actuate the drive assembly to move the jaw members; each jaw member adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue; and a switch (250, 260) disposed on the housing and being activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue, the switch being operatively coupled to an intensity control mechanism disposed within the housing, which is selectively adjustable to regulate the level of electrosurgical energy to at least one jaw member, the intensity control mechanism includes a first mechanical interface configured to engage a series of corresponding mechanical interfaces defined in the housing to regulate the level of electrosurgical energy in discreet increments, the first mechanical interface includes a detent and the corresponding mechanical interfaces defined within the housing include recesses (163a', 163b', 163c', 163d', 163e'), wherein the detent is disposed in a cantilevered fashion atop the intensity control mechanism.
