Abstract: Medical devices, such as forceps including a handpiece having a housing and an inner shaft that extends out of the handpiece along a longitudinal axis to transfer motion to an end effector. The inner shaft being rotatable with respect to the handpiece. An outer shaft that is rotatable with respect to the housing is loated around the inner shaft. The medical device further including an end effector coupled to the inner shaft and the outer shaft. The outer shaft rotationally constrained to the inner shaft at a first longitudinal location and at a second longitudinal location.

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.

Abstract: Forceps including a housing, a first body, a second body and a drive shaft. The first body has a passageway extending therethrough. The drive shaft extending through the passageway and connected to the first body such that the first body and the drive shaft are slidable with respect to the housing to drive jaws located at a distal portion of the drive shaft between an open position and a closed position. The second body having a second passageway. The drive shaft extending through the second passageway such that the second body is guided by the drive shaft and is slidable relative to the first body and the drive shaft to displace a blade shaft between a retracted position and an extended 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.

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: 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: 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.
