Abstract: Surgical forceps can include a jaw, a blade, and a tongue. The jaw can include a grip surface defining a slot. The blade can be configured to reciprocate along the slot between an extended position and a retracted position. The tongue can be connected to the jaw where at least a portion of the tongue can be located proximal of the grip surface to guide the blade into the blade slot when the blade moves from the retracted position into the blade slot.

Abstract: Surgical tool can include an outer shaft, a guide, an end effector, and a drive shaft. The outer shaft can extend along a longitudinal axis. The guide can be connected to the outer shaft. The end effector can include a first jaw connected to the outer shaft distal of the guide and a second jaw pivotably connected to the outer shaft distal of the guide. The drive shaft can be located within the outer shaft and can extend along the longitudinal axis. The drive shaft can be connected to the end effector and the drive shaft can be engageable with the guide to limit movement of the drive shaft with respect to the outer shaft in a direction not parallel with the guide. The drive shaft can be translatable along the outer shaft to operate the end effector.

Abstract: Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.

Abstract: Surgical forceps can include a drive pin an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can define a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a pair of flanges located at a proximal portion of the first jaw, where each flange can include a track receiving the drive pin. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can include a pair of arms extending from a distal portion of the inner tube. The drive pin can be securable to the pair of arms. The inner tube can be translatable within the outer tube to drive the drive pin along the tracks to move the second jaw between open and closed positions.

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 can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.
