Tool assembly for a surgical stapling device
A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.
Motor-driven surgical cutting instrument
A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.
Fastener cartridges including extensions having different configurations
A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.
Method of hub communication with surgical instrument systems
A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
Surgical stapling device
A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.
Cartridge lockout arrangements for rotary powered surgical cutting and stapling instruments
A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.
Surgical instrument including a drive assembly movable in a non-motorized mode of operation
A surgical instrument comprising a shaft, an end effector, a housing, a drive assembly, and a manually-driven actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a clamped position. The housing comprises a rotary input movable by a motor. The drive assembly is operably engaged with the rotary input. The drive assembly is movable by the motor in a motorized mode of operation to transition the second jaw toward the clamped position. The drive assembly is movable in a non-motorized mode of operation by the manually-driven actuator to permit a transition of the second jaw toward the open position to release tissue between the first jaw and the second jaw.
Surgical fastener applying apparatus
A surgical stapler includes a tubular body portion and a cartridge assembly disposed at a distal end of the body portion for expelling an annular array of staples. Each of the staples of the annular array of staples has a generally bent backspan. An anvil member disposed at the distal end of the tubular body portion is positioned opposite the cartridge assembly to clinch the staples in tissue upon expulsion of the staples from the cartridge assembly. The anvil member has a corresponding annular array of staple forming buckets. Each of the buckets is configured to accommodate the generally bent configuration of the staples to facilitate formation thereof.
Surgical dissectors configured to apply mechanical and electrical energy
A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.
Firing drive arrangements for surgical systems
An end effector assembly for use with a surgical instrument is disclosed. The end effector assembly comprises a staple cartridge jaw, a threaded rod, and a replaceable staple cartridge configured to be seated in the staple cartridge jaw. The replaceable staple cartridge comprises a proximal end, a distal end, a longitudinal slot extending between the proximal end and the distal end, and a driver configured to support a staple, wherein the driver comprises a surface facing the threaded rod, wherein the surface comprises a clearance, and wherein at least a portion of the threaded rod is configured to be received in the clearance when the replaceable staple cartridge is seated in the staple cartridge jaw.
