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: 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 as assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the as assembly is substantially rigid in the closed position.

Abstract: Medical devices for operating an end effector including a housing, a drive shaft, a drive body and a drive link. The drive shaft is moveable relative to the housing to actuate the end effector. The drive body is operably coupled to the drive shaft. The drive body includes a proximal collar and a distal collar. The drive link includes a proximal cam surface and distal cam surface, and the drive link is operatively coupled to the housing and actuatable to translate the drive shaft with respect to the housing. The proximal cam surface is configured to interface with the proximal collar when the drive link displaces proximally to translate the drive body in a proximal direction, and the distal cam surface is configured to interface with the distal collar when the drive link displaces distally to translate the drive shaft in a distal direction.

Abstract: An effector includes a tubular body having a proximal end and a distal end. The effector holds a plug or closure at the distal end of the tubular body; an active electrode at the distal end of the body; an insulator on the body; and one or more return electrodes on the insulator. The body dissipates heat generated by the one or more return electrodes from the distal end of the body to the proximal end of the body

Abstract: Forceps including a frame and a motion transfer assembly to transfer forces from or more actuators to an end effector. The motion transfer assembly can include a body having a passageway, a drive shaft extending through the passageway, and a drive link. The body and the drive shaft slidable with respect to the frame, and the body rotationally fixed to the drive shaft to transfer a rotational input received from a first actuator into a rotational motion of the drive shaft relative to the frame. The drive link operably coupled to the frame and the body to transfer a force received from a second actuator into a linear motion of the body and the drive shaft relative to the frame.

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.
