A surgical system comprises a handpiece and a battery. The handpiece includes a body, a handpiece controller, and a handpiece connector with a first coupler, a handpiece voltage terminal, and a handpiece data terminal. The battery has a housing, a cell, a battery controller, and a battery connector with a second coupler to rotatably engage the first coupler, a battery voltage terminal, and a battery data terminal. The second coupler receives the first coupler at an initial radial position and permits rotation to a first secured radial position and a second secured radial position. Rotation from the initial radial position to the first secured radial position engages the voltage terminals to transmit power between the cell and the handpiece controller, and rotation to the second secured radial position engages the data terminals to communicate data between the controllers while maintaining engagement between the voltage terminals.

A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the grasping components is movable relative to the other to a closed position wherein the tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

An adapter assembly for connecting a surgical reload to an electromechanical handle assembly, includes a trocar assembly release mechanism configured to releasably secure the trocar assembly within an outer tube. The release mechanism includes a release button supported in the outer tube and movable between an extended condition and a depressed condition; a spring clip slidably supported in the outer tube and connected to the release button; and a pair of lock cam pins supported within the outer tube, wherein each lock cam pin is secured to a respective leg of the spring clip, and wherein each lock cam pin is selectively receivable within a respective opening of the pair of openings formed in the trocar housing. The spring clip includes a backspan connected to the release button; and a pair of legs extending from the backspan.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

In various embodiments, a surgical instrument comprising an end effector and a handle comprising an opening and an access panel covering the opening is disclosed. The surgical instrument further comprises a motor, a power source, a firing member movable through a staple firing stroke and a retraction stroke, an end-of-stroke switch configured to be actuated to automatically retract the firing member through the retraction stroke, and a bailout switch configured to prevent power from flowing from the power source to the motor when the bailout switch is in an open state and permit power to flow from the power source to the motor when the bailout switch is in a closed state. A user of the surgical instrument is provided access to a retraction lever to manually retract the firing member through the retraction stroke when the access panel is in the open position.

A powered surgical instrument comprising a housing, an elongate shaft, an articulation joint, a rotary drive member configured to rotate in response to rotary motion from an electric motor, a coupling portion, and a stapling attachment releasably attachable to the coupling portion is disclosed. The stapling attachment is secured to the coupling portion by rotating one of the stapling attachment and the coupling portion relative to the other of the stapling attachment and the coupling portion. The stapling attachment comprises an elongate channel configured to receive a staple cartridge. The stapling attachment further comprises an anvil, a drive screw, and a firing member operably engaged with the drive screw. The coupling portion operably couples the rotary drive member and the drive screw when the stapling attachment is attached to the elongate shaft. The firing member is advanced distally within the stapling attachment when the drive screw is rotated.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

A surgical device includes a tool assembly and a handle assembly. The tool assembly includes a distal portion including a plurality of staples and an anvil assembly movable relative to the distal portion from an open position to a clamped position. The handle assembly includes an approximation mechanism coupled to the anvil assembly and configured to move the anvil assembly from the open position to the clamped position, a force sensor disposed at a distal end of the surgical device, and a controller. The force sensor is configured to sense a change in resistance indicating a force imparted on compressed tissue and on the approximation mechanism. The controller is configured to receive a signal indicative of a force measured by the force sensor and provide an indication of the sensed force.

A surgical instrument that comprises an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel relative thereto about an articulation axis that is laterally offset from the shaft axis and extends transversely relative thereto. An end effector driver link is operably coupled to the surgical end effector and an articulation driver that is supported for longitudinal travel in distal and proximal directions upon application of articulation motions thereto. A flexible de-articulation member is coupled to the elongate shaft assembly and the surgical end effector to apply de-articulation motions to the surgical end effector.
