Robotically-controlled shaft based rotary drive systems for surgical instruments

A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME

An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

JAW FOR A SURGICAL TUBULAR SHAFT INSTRUMENT
20170367688 · 2017-12-28 ·

A jaw assembly for a surgical tubular shaft instrument includes a supporting component, a first arm and a second arm, the first arm and/or the second arm each having one link element. The arms are held by the supporting component in the axial direction. A cam carrier element is axially movable relative to the supporting component and carries at least two cams. Each link element is designed to be in contact with at least two cams when there is a relative axial movement between the supporting component and the cam carrier element, the cams being provided on the cam carrier element. Each link element is further designed to slide off of the cams to effect an opening or closing of the jaw assembly.

Surgical instrument systems comprising an articulatable end effector and means for adjusting the firing stroke of a firing member

A surgical instrument is disclosed. The surgical instrument can include an end effector, comprising an anvil and a staple cartridge. The surgical instrument can further include a shaft defining a longitudinal axis. The surgical instrument can also include an articulation joint, wherein the end effector is rotatably connected to the shaft about the articulation joint between an unarticulated position and at least one articulated position. The surgical instrument can include means for adjusting the length of a firing stroke as a function of the degree in which the end effector is articulated relative to the longitudinal axis. The surgical instrument can include a sensor configured to defect shifting of lateral portions of a flexible firing bar that extends through the articulation joint. Additionally or alternatively, the surgical instrument can include a relief feature configured to accommodate shifting of lateral portions of a flexible firing bar.

Surgical instrument including a flexible support configured to support a flexible firing member

A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

Atraumatic microsurgical forceps
09795506 · 2017-10-24 · ·

An atraumatic microsurgical forceps may include an actuation structure, an actuation sleeve having an actuation sleeve distal end and an actuation sleeve proximal end, a surgical blank, and atraumatic forceps jaws of the surgical blank having atraumatic forceps jaws distal ends and atraumatic forceps jaws proximal ends. The surgical blank may be disposed within the actuation sleeve wherein at least a portion of the atraumatic forceps jaws extends from the actuation sleeve distal end. A compression of the actuation structure may be configured to gradually extend the actuation sleeve over the atraumatic forceps jaws proximal ends. An extension of the actuation sleeve over the atraumatic forceps jaws proximal ends may be configured to gradually close the atraumatic forceps jaws wherein the atraumatic forceps jaws initially contact at the atraumatic forceps jaws distal ends.

Devices and methods for facilitating closing and clamping of an end effector of a surgical device

Devices and methods are provided for facilitating closing and clamping of an end effector of a surgical device. In general, the devices and methods can be configured to increase a moment arm of the end effector, thereby increasing a closure force of the end effector. In an exemplary embodiment, a surgical device can include a closure mechanism configured to provide an increased moment arm at the device's end effector, such as at a proximal end thereof.
