A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.

Surgical instrument having force feedback capabilities

Surgical stapling instruments having surgical stapling cartridges are disclosed. At least one embodiment includes an end effector that has an elongate channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto. An anvil lock member cooperates with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel. Surgical staple cartridges are configured to move the anvil from an open position to an actuatable position when the cartridge has been installed in the end effector.

Surgical stapling device with lockout system for preventing actuation in the absence of an installed staple cartridge

A surgical instrument includes a handle assembly, an elongate shaft, an end effector, and control system having a processor and a memory. The handle assembly is movable between a plurality of positions and includes an interface. The control system can cause the processor to toggle between a plurality of interface configurations each associated with one of the positions of the handle assembly. Additionally, or alternatively, the control system can toggle the interface between a primary interface configuration with operational controls and a secondary interface configuration with navigation controls. Additionally, or alternatively, the interface can include a touchscreen configured to provide a firing input signal to the processor. Additionally, or alternatively, a surgical assembly can include the surgical instrument and a remote operating unit with a secondary interface configured to control the end effector.

Surgical instrument with multiple interface configurations

A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.

Stapling instrument comprising a mounted shaft orientation sensor

A surgical stapler kit includes a surgical stapler having a body, a shaft, and an end effector. The kit includes a first staple cartridge having a first cartridge body and a first sled, and a second staple cartridge having a second cartridge body and a second sled. When the first staple cartridge is at least partially seated within a cartridge jaw with the first sled in a proximal undisplaced position, a knife drives the first sled distally to deploy staples from the first cartridge body. When the second staple cartridge is at least partially seated within the cartridge jaw with the second sled in a proximal undisplaced position, the knife advances distally into a lockout position before causing any staples to be deployed from the second cartridge body.

Incompatible staple cartridge use prevention features for surgical stapler

The present disclosure provides a surgical instrument including an end effector, a drive member movable to effectuate a motion in said end effector, a motor operable to move the drive member to effectuate the motion in the end effector and a bailout assembly operable to perform a mechanical bailout of the surgical instrument in response to a bailout error. The bailout assembly includes a bailout door, a bailout handle accessible through the bailout door. The bailout handle is operable to move the drive member to effectuate a bailout motion in the end effector. A controller includes a memory and a processor coupled to the memory. The processor is configured to detect the bailout error. The processor is programed to stop the motor in response to the detection of the bailout error.

Feedback algorithms for manual bailout systems for surgical instruments

A surgical instrument having a shaft, an end effector, a firing system, and a control system is disclosed herein. The firing member is configured to translate an electric motor through a firing stroke. The control system includes a pulse width modulation circuit configured to adjust a duty cycle of voltage pulses to drive the firing system to a target speed. The control system includes a control circuit configured to evaluate the duty cycle of pulses at a predetermined adjustment point and set the target speed based at least in part on the comparison (maintain or new speed). The controls system may be configured to set the target speed at two or more adjustment points during the firing stroke and/or evaluate the duty cycle of pulses at an adjustment point more than half way through the firing stroke.

Surgical instrument with firing stroke target speed adjustment

The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

Systems and methods for controlling a segmented circuit

A surgical stapler having an end effector, a firing drive electric motor, and a control circuit is disclosed. The firing drive electric motor is configured to actuate a staple firing stroke of the end effector. The control circuit can be configured to provide a pulse width modulated (PWM) electrical signal to the firing drive electric motor and adjust a duty cycle of the PWM electrical signal based at least in part on a speed of the staple firing stroke. The control circuit can further be configured to provide a pulse width modulated (PWM) electrical signal to the firing drive electric motor, adjust a duty cycle of the PWM electrical signal based at least in part on a target speed of a staple firing stroke, and lower the target speed in response to the duty cycle exceeding a safety threshold value.
