Abstract

Various systems and methods of controlling a surgical instrument are disclosed. In one aspect, the surgical instrument includes a displacement member movable between a first position and a second position, a sensor configured to detect the position of the displacement member, and a display. The surgical instrument is configured to determine whether the surgical instrument is in a firing state and cause the display to display the position of the displacement member upon the surgical instrument being in the firing state.

Claims

1. A surgical instrument comprising:

a displacement member movable between a first position and a second position;

a sensor configured to detect a position of the displacement member and provide a signal indicative thereof;

an electronic display screen configured to display a graphical user interface; and

a control circuit coupled to the electronic display screen and the sensor, the control circuit configured to;

determine whether the surgical instrument is in a firing state; and

cause the graphical user interface display to display the position of the displacement member upon the surgical instrument being in the firing state.

2. The surgical instrument of claim 1, wherein the position of the displacement member is displayed as a numerical value.

3. The surgical instrument of claim 2, wherein the numerical value corresponds to a distance between the position of the displacement member and the first position.

4. The surgical instrument of claim 2, wherein the numerical value corresponds to a distance of a cut line of the surgical instrument.

5. The surgical instrument of claim 2, wherein the control circuit is configured to verify the numerical value via a second sensor.

6. The surgical instrument of claim 2, wherein the numerical value is displayed in increments of one millimeter.

7. The surgical instrument of claim 1, wherein the position of the displacement member is displayed as a graphic.

8. The surgical instrument of claim 1, further comprising:

an end effector movable between a clamped position and an unclamped position; and

a firing trigger coupled to the displacement member, the firing trigger movable between an unactuated position and an actuated position to drive the displacement member between the first position and the second position;

wherein the control circuit is configured to determine whether the surgical instrument is in the firing state according to whether the end effector is in the clamped position and the firing trigger is in the actuated position.

21. The surgical instrument of claim 1, wherein the control circuit is further configured to update the position of the displacement member as displayed on the graphical user interface as the displacement member moves from the first position to the second position.

9. A surgical instrument comprising:

a knife bar;

a displacement member coupled to the knife bar, the displacement member movable between a first position and a second position;

a sensor configured to detect a position of the displacement member and provide a signal indicative thereof;

an electronic display screen configured to display a graphical user interface; and

a control circuit coupled to the electronic display screen and the sensor, the control circuit configured to;

determine whether the knife bar is firing; and

cause the graphical user interface display to display a position of the knife bar corresponding to the position of the displacement member upon the knife bar firing.

10. The surgical instrument of claim 9, wherein the position of the displacement member is displayed as a numerical value.

11. The surgical instrument of claim 10, wherein the numerical value corresponds to a distance between the position of the displacement member and the first position.

12. The surgical instrument of claim 10, wherein the numerical value corresponds to a distance of a cut line of the surgical instrument.

13. The surgical instrument of claim 10, wherein the control circuit is configured to verify the numerical value via a second sensor.

14. The surgical instrument of claim 10, wherein the numerical value is displayed in increments of one millimeter.

15. The surgical instrument of claim 9, wherein the position of the displacement member is displayed as a graphic.

16. The surgical instrument of claim 9, further comprising:

an end effector movable between a clamped position and an unclamped position; and

a firing trigger coupled to the displacement member, the firing trigger movable between an unactuated position and an actuated position to drive the displacement member between the first position and the second position;

wherein the control circuit is configured to determine whether the knife bar is firing according to whether the end effector is in the clamped position and the firing trigger is in the actuated position.

22. The surgical instrument of claim 9, wherein the control circuit is further configured to update the position of the knife bar corresponding to the position of the displacement member as displayed on the graphical user interface as the displacement member moves from the first position to the second position.

17. A method of controlling a surgical instrument comprising a displacement member movable between a first position and a second position, a sensor configured to detect a position of the displacement member and provide a signal indicative thereof, and an electronic display screen configured to display a graphical user interface, the method comprising:

determining whether the surgical instrument is in a firing state; and

displaying the position of the displacement member on the graphical user interface upon the surgical instrument being in a firing state.

18. The method of claim 17, wherein the position of the displacement member is displayed numerically.

19. The method of claim 17, wherein the position of the displacement member is displayed graphically.

20. The method of claim 17, the surgical instrument further comprising an end effector including a clamped position and a firing trigger coupled to the displacement member, the firing trigger including an actuated position, wherein whether the surgical instrument is in a firing state is determined according to whether the end effector is in the clamped position and the firing trigger is in the actuated position.

23. The method of claim 17, further comprising updating the position of the displacement member as displayed on the graphical user interface as the displacement member moves from the first position to the second position.
