Abstract: A surgical device comprising: (a) a first jaw; (b) a second jaw opposing the first jaw, the first jaw, the second jaw, or both being movable relative to one another between a jaw nominal position and a jaw clamped position; (c) a clamp lever in communication with the first jaw and the second jaw, the clamp lever moving the first jaw, the second jaw, or both from the jaw nominal position to the jaw clamped position when an external force is imparted upon the clamp lever in a first direction; and (d) a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest; wherein the first jaw and the second jaw are movable from the jaw nominal position to a jaw spread position when the clamp lever is moved in a second direction that opposes the first direction by an external force deforming the stop bias member so that a distance between the first jaw and the second jaw is larger in the jaw spread position than in the jaw nominal position.

Abstract: An instrument that includes forceps. The forceps include a jaw assembly. The jaw assembly includes a first jaw and a second jaw. The first jaw includes a gripping section, and the second jaw includes a gripping section. The jaw assembly is moveable between an open position and a closed position. The first jaw is electrically conductive, the second jaw is electrically conductive, or both the first jaw and the second jaw are electrically conductive. The first jaw includes a first tissue stop that is centered on a medial plane of the first jaw. The tissue stop extends from the first jaw towards the second jaw. The first tissue stop is adapted to block an anatomical feature from extending beyond a proximal end of the gripping section of the first jaw, a proximal end of the gripping section of the second jaw, or both.

Abstract: A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position, in the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

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: Forceps that include a hand piece, a jaw assembly connected to the hand piece, and a web. The jaw assembly is moveable between an open position and a closed position. The web is adapted to block an anatomical feature from extending beyond a proximal end of a gripping section of the jaw assembly. The web remains generally stationary relative to the handpiece when the jaw assembly is moved between an open position and a closed position.

Abstract: A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion. A pin extends through the first slot, the second slot, and the third slot to prevent deployment of the rod when the pin is in the locking portion and to permit deployment of the rod when the pin is in the guide track portion. A first actuator produces relative movement of the first and second shafts to move the jaws relative to each other and move the pin from the locking portion to the guide track portion of the third slot. A second actuator produces movement of the rod to deploy the rod when the pin is in the guide track portion.
