Surgical instruments with segmented flexible drive arrangements

Surgical instruments with axially movable firing members that are driven by a series of drive components that are loosely linked to each other when traversing an articulation joint of the surgical instrument. The drive components are configured to serially engage a rotary drive member located distal to the articulation joint such that the rotary drive member causes the drive components to form an axially rigid series of said drive components configured to apply an axial drive motion to the firing member.

SURGICAL INSTRUMENT WITH LOCKOUT MECHANISM

Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.

METHOD FOR OPERATING A SURGICAL STAPLING SYSTEM

A surgical instrument system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.

Systems and methods for controlling motor speed according to user input for a surgical instrument

A surgical system is disclosed comprising a firing member movable from a proximal position toward a distal position during a firing stroke, a motor configured to drive the firing member toward the distal position, and a control system configured to operate in an open-loop configuration and a closed-loop configuration. In the open-loop configuration, the control system is configured to cause the motor to drive the firing member to a predetermined position between the proximal position and the distal position, determine a time required to drive the firing member to the predetermined position, compare the determined time to a predetermined time, and set a motor velocity of the motor based on the comparison. In the closed-loop configuration, the control system is configured to drive the firing member at the set motor velocity.

Staple cartridge comprising sensor array which may be embedded in cartridge body

A staple cartridge comprising a sensor array is disclosed. In various instances, the sensor array comprises a conductive trace embedded in a cartridge body of the staple cartridge.

Powered surgical cutting and stapling apparatus with manually retractable firing system

In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

SURGICAL INSTRUMENT WITH MULTIPLE PROGRAM RESPONSES DURING A FIRING MOTION

A surgical instrument. The surgical instrument includes an elongated channel configured to support a staple cartridge, an anvil pivotably connected to the elongated channel, a knife mechanically coupled to the staple cartridge, an electric motor and a control circuit electrically connected to the electric motor. The control circuit is configured to change a firing motion a first way based on a first value of a projected peak firing force and a second way based on a second value of the projected peak firing force value.

METHOD OF USING A POWERED STAPLING DEVICE

A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component.
