Surgical stapling system comprising a controller configured to cause a motor to reset a firing sequence
A surgical stapling system comprising an end effector, a shaft assembly, a motor configured to generate rotary motions, a housing, a firing member, a flexible drive member, a feedback device, and a controller is disclosed. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples deployable during a firing sequence. The controller comprises a processor. The controller is configured to determine that the firing sequence cannot be completed, cause the feedback device to display an alert that the firing sequence cannot be completed, and cause the motor to reset the firing sequence based on determining that the firing sequence cannot be completed.
1. A surgical stapling system, comprising:
an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw from an open configuration to a closed configuration; and
a staple cartridge comprising staples deployable from the staple cartridge into tissue between the first jaw and the second jaw during a firing sequence;
a shaft assembly proximal to the end effector, wherein the shaft assembly defines a longitudinal axis, and wherein the shaft assembly comprises a rotary interface at a proximal portion of the shaft assembly;
a motor configured to generate rotational motions;
a housing couplable to the shaft assembly, wherein the housing comprises a drive connector operably coupled to the motor, wherein the drive connector is configured to engage and transmit the rotational motions to the rotary interface;
a firing member, comprising:
a first camming portion configured to engage the first jaw; and
a second camming portion configured to engage the second jaw;
a flexible drive member proximal to the firing member, wherein the rotary interface is operably coupled to the flexible drive member, wherein the rotary interface is configured to cause the flexible drive member to advance the firing member toward a distal position to motivate a deployment of the staples from the staple cartridge during the firing sequence;
a feedback device; and
a controller comprising a processor, wherein the controller is configured to:
determine that the firing sequence cannot be completed;
cause the feedback device to display an alert that the firing sequence cannot be completed; and
cause the motor to reset the firing sequence based on determining that the firing sequence cannot be completed.
2. The surgical stapling system of claim 1 , wherein the motor is configured to reset the firing sequence by causing the rotary interface to cause the flexible drive member to retract the firing member proximally away from the distal position to permit a transition of the second jaw toward the open configuration.
3. The surgical stapling system of claim 2 , further comprising a sensor, wherein the controller is configured to determine that the firing sequence cannot be completed based on sensor measurement data received from the sensor.
4. The surgical stapling system of claim 3 , wherein the sensor measurement data comprises measurement data indicative of a current draw by the motor.
5. The surgical stapling system of claim 2 , further comprising a sensor, wherein the controller is configured to determine that the firing sequence cannot be completed based on a comparison between sensor measurement data received from the sensor and a predetermined threshold.
6. The surgical stapling system of claim 5 , wherein the sensor measurement data comprises measurement data indicative of a current draw by the motor.
7. The surgical stapling system of claim 1 , further comprising a user interface, wherein the controller is configured to accept a user input from the user interface.
8. The surgical stapling system of claim 7 , wherein the user interface comprises a switch.
9. The surgical stapling system of claim 1 , wherein the drive connector is a first drive connector and the rotary interface is a first rotary interface, wherein the shaft assembly comprises a second rotary interface, and wherein the housing comprises a second drive connector configured to operably engage and rotate the second rotary interface to cause an articulation of the end effector relative to the shaft assembly and away from the longitudinal axis.
10. A surgical stapling system, comprising:
an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw from an open configuration to a closed configuration; and
a staple cartridge comprising staples deployable from the staple cartridge into tissue between the first jaw and the second jaw during a firing sequence;
a shaft assembly extending proximally from the end effector;
a feedback device;
a motor;
a firing member, comprising:
a first camming portion configured to engage the first jaw; and
a second camming portion configured to engage the second jaw;
a flexible drive member proximal to the firing member, wherein the motor is configured to cause the flexible drive member to advance the firing member toward a distal position to motivate a deployment of the staples from the staple cartridge during the firing sequence; and
a controller comprising a processor, wherein the controller is configured to:
determine that the firing sequence cannot be completed;
cause the feedback device to display an alert that the firing sequence cannot be completed; and
cause the motor to reset the firing sequence based on determining that the firing sequence cannot be completed.
11. The surgical stapling system of claim 10 , wherein the motor is configured to reset the firing sequence by causing the flexible drive member to retract the firing member proximally away from the distal position to permit a transition of the second jaw toward the open configuration.
12. The surgical stapling system of claim 11 , further comprising a sensor, wherein the controller is configured to determine that the firing sequence cannot be completed based on sensor measurement data received from the sensor.
13. The surgical stapling system of claim 12 , wherein the sensor measurement data comprises measurement data indicative of a current draw by the motor.
14. The surgical stapling system of claim 11 , further comprising a sensor, wherein the controller is configured to determine that the firing sequence cannot be completed based on a comparison between sensor measurement data received from the sensor and a predetermined threshold.
15. The surgical stapling system of claim 14 , wherein the sensor measurement data comprises measurement data indicative of a current draw by the motor.
16. The surgical stapling system of claim 11 , further comprising a user interface, wherein the controller is configured to accept a user input from the user interface.
17. The surgical stapling system of claim 16 , wherein the user interface comprises a switch.
