Stapling instrument for use with a robotic system

A stapling instrument for use with a robotic surgical system is disclosed. The stapling instrument comprises a housing, a shaft, a loading unit, a firing drive, an articulation drive, and a rotation drive. The housing comprises a first, second, and third rotatable members. The loading unit comprises a staple cartridge and a firing drive. The firing drive is operably coupled to the first rotatable member and configured to convert rotary motion of the first rotatable member to linear motion to eject staples from the staple cartridge. The articulation drive is operably coupled to the second rotatable member and configured to convert rotary motion of the second rotatable member to linear motion to articulate a first jaw and a second jaw of the loading unit. The rotation drive is configured to rotate the shaft about a longitudinal axis and is operably coupled to the third rotatable member.

Layer of material for a surgical end effector

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

ROBOTICALLY-CONTROLLED SURGICAL INSTRUMENT WITH SELECTIVELY ARTICULATABLE END EFFECTOR

Devices and systems are provided for controlling movement of a working end of a surgical device by means of a robotic system. In one embodiment, systems and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting.

Surgical stapling apparatus including an articulation system

A surgical stapling apparatus for use with a surgical instrument system is disclosed. The surgical stapling apparatus comprises a housing assembly, a shaft, a proximal segment, a distal segment, and an articulation system. The proximal segment comprises a first proximal end and a first distal end comprising an articulating segment. The distal segment comprises a second proximal end and a second distal end. The second proximal end comprises a pivot segment configured to be coupled with the articulating segment. The second distal end is configured to be attached to a stapling assembly. The articulation system is operably engaged with the distal segment to transmit a first articulation motion to the distal segment to cause the stapling assembly to articulate in a first plane and a second articulation motion to the distal segment to cause the stapling assembly to articulate in a second plane that is different than the first plane.

STAPLE FORMING POCKET CONFIGURATIONS FOR CIRCULAR SURGICAL STAPLER ANVIL

An anvil for a circular surgical stapler includes an anvil surface and an anvil shaft. The anvil surface defines an inner annular array of staple forming pockets and an outer annular array of staple forming pockets. The inner annular array of staple forming pockets includes a plurality of staple forming pocket pairs. The outer annular array of staple forming pockets also includes a plurality of staple forming pocket pairs. The outer annular array of staple forming pockets is arranged in a mirrored symmetry with the inner annular array of staple forming pockets. The anvil shaft is configured to couple with a stapling head assembly of a surgical stapler.

Surgical instrument with spot coagulation control and algorithm

A surgical instrument includes an end effector that has an ultrasonic blade and a clamp arm that is movable relative to the ultrasonic blade from an opened position toward a closed position. The ultrasonic blade and the clamp arm are able to receive tissue in the opened position, and the clamp arm is able to clamp tissue against the ultrasonic blade in the closed position. There is a first electrode connected with the clamp arm, and a second electrode associated with the ultrasonic blade. The electrodes are able to apply bipolar radiofrequency (RF) energy to tissue captured in the end effector. The instrument further has a first button for activating the ultrasonic blade to provide a cutting and sealing mode at the end effector. There is also a second button for activating the electrodes to provide a spot coagulation mode at the end effector.

Circular surgical stapler with angularly asymmetric deck features

An apparatus includes a body, a shaft assembly, a stapling head assembly, and an anvil. The stapling head assembly includes a deck member, a plurality of staples, and a driver. The deck member includes a first deck surface, a second deck surface, an outer annular array of staple openings formed through the deck surfaces, an inner annular array of staple openings formed through the deck surfaces, and a plurality of stand-off features extending distally from the second deck surface. The second deck surface is recessed relative to the first deck surface. The driver is operable to drive the staples through the staple openings. The anvil is operable to compress tissue against the deck surface.

Rotation control systems for surgical instruments

A surgical instrument includes a handle assembly, an elongate member, and a motor assembly. The elongate member extends from the handle assembly and defines a longitudinal axis of the surgical instrument. The motor assembly is disposed within the handle assembly and is configured to rotate the elongate member about the longitudinal axis relative to that handle assembly in response to sensed movement of the handle assembly about the longitudinal axis.

Gas supply unit and substrate processing apparatus including the gas supply unit

A substrate processing apparatus having an improved film processing uniformity is provided. The substrate processing apparatus includes a partition configured to provide a gas supply channel and a gas supply unit connected to the gas supply channel. A gas flow channel communicating with the gas supply channel is formed in the gas supply unit. A first through-hole is formed to penetrate through at least a part of the partition. A second through-hole is formed to penetrate through at least a part of the gas supply unit. The first through-hole communicates with the gas flow channel via the second through-hole. The second through-hole is arranged between a center and an edge of the gas flow channel, and is arranged spaced apart from the edge.
