Forceps including a handpiece configured to transfer motion from an actuator to an end effector of the forceps. The handpiece including: a lumen extending through a portion of the handpiece; a sleeve affixed to the handpiece, the sleeve extending through at least a portion of the lumen; and a shaft extending into the sleeve and affixed to the sleeve.

Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.

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.

A stopper according to one or more embodiments may include: a stopper body; and a rotation restriction portion provided at the stopper body and configured to restrict rotations of the drive transmission member. The stopper may be configured such that the rotation restriction portion restricts the rotations of the drive transmission member in a state where the stopper body is attached to the adaptor main body and the rotation restriction portion releases the restriction of the rotations of the drive transmission member in a state where the stopper body is detached from the adaptor main body.

An integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, an output assembly, and a plurality of planetary gears each having a plurality of gear teeth. The shaft assembly is configured to cause rotation of the planetary gears with a sun gear. The rotation of the planetary gears is configured to cause rotation of an output shaft, with a reduction of rotational speed relative to the rotation of the shaft assembly.

A device comprising: (a) one or more markers, some or all of which are expandable rounded members that are expandable from a stored state to an expanded state and when in the expanded state each of the expandable rounded members expand to move into contact with a lumen in an organ; and (b) one or more tissue tags connected to the expandable rounded members or the expandable rounded members being made of a magnetized material; and wherein the expandable rounded members are configured to be located within and deployed from an insertion mechanism into the lumen in the organ.

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.

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.

A surgical instrument including a handle assembly, an elongated portion, an end effector, and a stop member is disclosed. The end effector is disposed adjacent a distal portion of the elongated portion and includes a first jaw member and a second jaw member. At least one jaw member is movable with respect to the other jaw member between spaced and approximated positions. The first jaw member includes an upper tissue-contacting surface and a lower shelf portion. The shelf portion includes a groove disposed therein. The stop member is disposed adjacent a distal portion of the first jaw member and is pivotable with respect to the first jaw member between a first position, a significant portion of the stop member being positioned external to the first jaw member, and a second position where a lower portion of the stop member being positioned at least partially within the groove.

The present disclosure relates to a hub assembly for use with an endoscopic assembly of a reposable surgical clip applier having an outer housing defining a channel therethrough, a driver gear slidably disposed within the channel, and a display gear slidably and rotatably disposed within the channel and including first and second plurality of teeth. Distal advancement of the driver gear causes the display gear to advance in a distal direction such that the second plurality of teeth engage a portion of the driver gear and causes the display gear to rotate in a first direction. Retraction of driver gear causes the display gear to translate in a proximal direction such that the first plurality of teeth engage a portion of the channel and causes the drive gear to further rotate in the first direction.
