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.

Local display of tissue parameter stabilization

A powered surgical stapling assembly comprising a motor, an end effector, a sensor, a display, and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw movable relative to the first jaw. The end effector is configured to clamp tissue between the first jaw and the second jaw. The sensor is configured to measure a parameter of the tissue clamped within the end effector. The control circuit is configured to monitor the parameter sensed by the sensor and identify when the monitored parameter stabilizes within a stabilization range. The monitored parameter is considered stable when a rate at which the monitored parameter changes falls below a predetermine threshold rate of change. The control circuit is further configured to display to a user when the parameter stabilizes.

METHOD OF HUB COMMUNICATION WITH SURGICAL INSTRUMENT SYSTEMS

A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.

Motor-driven surgical cutting and fastening instrument with position feedback

A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end effector by the clamping member when the clamping member is in a clamped position. The instrument may also comprise a main drive shaft assembly for actuating the cutting instrument in the end effector, a gear drive train connected to the main drive shaft assembly, and a motor for actuating the gear drive train. The instrument may also includes a closure trigger and a firing trigger, separate from the closure trigger, for actuating the motor when the firing trigger is retracted. Also, the instrument may comprise a mechanical closure system connected to the closure trigger and to the clamping member for causing the clamping member to pivot to the clamped position when the closure trigger is retracted.

Surgical instrument having force feedback capabilities

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.

Robotically-controlled shaft based rotary drive systems for surgical instruments

A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

SYSTEMS AND METHODS FOR CONTROLLING A SURGICAL STAPLING AND CUTTING INSTRUMENT

Various examples are directed to systems and methods for operating a surgical instrument comprising a firing member translatable proximally and distally along a longitudinal axis between a stroke begin position to a stroke end position distal of the stroke begin position; a knife coupled to the firing member; and a motor coupled to the firing member to translate the firing member between the stroke begin position and the stroke end position. A control circuit may receive a firing signal and begin a firing member stroke by providing an initial motor setting to the motor. The control circuit may maintain the initial motor setting for an open-loop portion of the firing member stroke. The control circuit may receive firing member motion data describing a motion of the firing member during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the motion of the firing member during the open-loop portion of the firing member stroke.

STAMPED STAPLES AND STAPLE CARTRIDGES USING THE SAME

A staple cartridge assembly is disclosed which comprises staples including a crown, a cam surface extending from the crown, one or more staple legs, and one or more connectors which connect the staple legs to the crown. The staple cartridge assembly further comprises a sled configured to engage the cam surfaces of the staples but not the connectors.

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.
