A surgical system comprising an end effector, a closure driver, a force sensor, and a control circuit 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 closed position. The closure driver is configured to apply a closure force to the second jaw to rotate the second jaw toward the closed position. The force sensor is to measure a parameter indicative of the closure force. The control circuit is to receive an output of the force sensor indicative of the parameter and set a velocity of the closure driver based on the received output and a force threshold.

A loading unit for use with a surgical stapling instrument is disclosed. The loading unit comprises a shaft and an end effector extending from the shaft. The end effector comprises a first jaw that comprising an anvil, and a second jaw. At least one of the first jaw and the second jaw is movable relative to the other to grasp tissue. The second jaw comprises an elongated channel comprising retaining features, and a staple cartridge insertable into the elongated channel for assembly therewith. The staple cartridge comprises a cartridge pan, and a sled translatable relative to the cartridge pan from a first position toward a second position. The retaining features are configured to resist a movement by the sled beyond the first position up to a predetermined force.

Surgical instruments with interactive features to remedy incidental sled movements

A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Surgical instrument with selectively actuated gap-setting features for end effector

A surgical system for use in a surgical procedure is disclosed. The surgical system includes a surgical instrument including an end effector configured to treat tissue at a surgical field during the surgical procedure, a surgical visualization system configured to track the surgical instrument in the surgical field, and a control circuit configured to derive a first data set from the surgical visualization system indicative of a visual aspect of the surgical instrument relative to the surgical field, derive a second data set from the surgical instrument indicative of a functional aspect of the surgical instrument, and correlate the first data set with the second data set.

Surgical systems correlating visualization data and powered surgical instrument data

An end effector for use with a surgical stapling instrument. The end effector comprises a first jaw and a second jaw. The first jaw comprises an anvil comprising a proximal camming member. At least one jaw is movable relative to the other to close the end effector. The second jaw comprises an elongated channel comprising a proximal channel aperture and a staple cartridge insertable into the elongated channel. The staple cartridge comprises a cartridge body and a cartridge pan. The cartridge pan comprises a proximal pan aperture configured to be positioned partially distal to the proximal channel aperture when the staple cartridge is assembled with the elongated channel in an unlocked configuration. The camming member is configured to proximally translate the cartridge pan relative to the cartridge body from the unlocked configuration to a locked configuration during a transition of the end effector to a closed configuration.

Surgical instrument with cartridge release mechanisms

A method for generating and updating a three-dimensional representation of a surgical site based on imaging data from an imaging system is disclosed. The method comprises the steps of generating a first image of the surgical site based on structured electromagnetic radiation emitted from the imaging system, receiving a second image of the surgical site, aligning the first image and the second image, generating a three-dimensional representation of the surgical site based on the first image and the second image as aligned, displaying the three-dimensional representation on a display screen, receiving a user selection to manipulate the three-dimensional representation, and updating the three-dimensional representation as displayed on the display screen from a first state to a second state according to the received user selection.

Surgical hub for use with a surgical system in a surgical procedure

A method includes positioning a surgical tool with an end effector adjacent a surgical site, the end effector including a housing having a tapered section that defines an inner surface, first and second arcuate jaw members protruding distally from the housing and defining a channel therebetween, each arcuate jaw member exhibiting a curved profile shaped to receive an arcuate surgical clip, and a feedbar movable within the housing. The method further including urging the arcuate surgical clip against the inner surface, advancing the feedbar within the housing to engage and follow the inner surface and thereby flexing the feedbar downward and into engagement with the arcuate surgical clip, advancing the arcuate surgical clip with the feedbar into interposition between the first and second arcuate jaw members, and collapsing the first and second arcuate jaw members to crimp the arcuate surgical clip.

An electrosurgical instrument comprising a housing, a shaft extending from the housing, an end effector extending from the shaft, an articulation joint rotatably connecting the end effector to the shaft, and a wiring circuit is disclosed. The housing comprises a printed control board. The wiring circuit extends from the printed control board through the shaft and into the end effector. The wiring circuit is configured to monitor a function of the end effector and communicate the monitored function to the printed control board. The wiring circuit comprises a proximal rigid portion fixed to the shaft, a distal rigid portion fixed to the end effector, and an intermediate portion extending from the proximal rigid portion to the distal rigid portion. The intermediate portion comprises a resilient portion and a stretchable portion.

Electrosurgical instrument with flexible wiring assemblies

A method for performing an electrosurgical procedure using an electrosurgical instrument including an end effector is disclosed. The method comprises applying a bipolar energy to a target tissue grasped by the end effector in a tissue-feathering segment, applying an energy blend of the bipolar energy and a monopolar energy to the target tissue in a tissue-warming segment and a tissue-sealing segment following the tissue-warming segment, and discontinuing the bipolar energy but continuing to apply the monopolar energy to the target tissue in a tissue-cutting segment following the tissue-sealing segment.
