Abstract: A surgical tool can include a handle, an outer tube, an end effector, an inner tube, and a guide tube. The outer tube can be connected to the handle and can extend along a longitudinal axis. The end effector can be connected to the outer tube. The inner shaft can be located within the outer tube and can extend along the longitudinal axis. The inner shaft can be connected to the end effector and the outer shaft. The handle can be operable to translate the inner shaft with respect to the outer tube to operate the end effector. The guide tube can be located within the outer tube between the handle and the end effector. The guide tube can include a conduit extending therethrough.

Abstract: The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed 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: 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.
