Abstract: A forceps includes an end effector assembly with a first jaw having a tissue sealing surface and an electrode on the sealing surface, and a second jaw having a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a flexible medial section and rigid lateral sections.

Abstract: A surgical device comprising: a closure assembly including: (a) a latch unit comprising: (A) a hook latch, having a home position, (B) a forward bias constraint, (C) a rearward bias constraint, and (D) a bias member extending between the forward bias constraint and the rearward bias constraint so that the bias member has a pre-load when the hook latch is in the home position; (b) a movement unit including a bar that is movable relative to the latch unit so that the bar is movable in a prescribed motion into contact with the latch unit to create a locked state; and wherein the bar moves into contact with the hook latch driving the hook latch in a first direction, away relative to the home position, and then the hook latch is moved by the bar in a second direction relative to the home position, and a loading of the bias member is increased from the pre-load when the hook latch is moved in either the first direction away from the home position or the second direction away from the home position.

Abstract: A surgical device comprising: a closure assembly comprising: (a) a movement unit including (i) a bar and (ii) a contact element, wherein the bar, the contact element, or both move in a direction of a prescribed motion; (b) a latch unit comprising: (i) a latch plate including: (1) a hook latch that selectively receives the bar, the latch plate being movable between: (A) a lockable state where the hook latch is engageable by the bar, and (B) an unlockable state where the hook latch is unengageable by the bar; (c) an indicator mechanism that moves into alignment with the prescribed motion of the contact element, the bar, or both when the latch unit is in the unlockable state so that the indicator is contacted by the bar, the contacting element, or both generating an indication.

Abstract: An instrument that includes an outer member, an inner member, and a jaw assembly. The inner member includes a first arm and a second arm. The jaw assembly includes a first jaw and a second jaw. The first jaw is connected to the first arm at a first pivot joint and to the outer member at a second pivot joint. The second jaw is connected to the second arm at a third pivot joint and to the outer member at a fourth pivot joint. The inner member is adapted to be moved distally relative to the outer member so that the first jaw pivots about the second pivot joint towards the second jaw and the second jaw pivots about the fourth pivot joint towards the first jaw thus moving the jaw assembly from the open position towards the closed position.
