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: A surgical device that includes a first support member extending along a longitudinal axis; a bladder located on the first support member; a first sealing member located on the bladder; and a second sealing member located on the bladder. The sealing member is located on one side of the longitudinal axis; and the second sealing member is located on another side of the longitudinal axis. The bladder is inflatable, and inflating the bladder changes a position of the first sealing member, the second sealing member, or both relative to the first support member.

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.
