Abstract

A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, and a position sensor coupled to the control circuit. The control circuit is configured to determine a velocity of the displacement member via the position sensor, and cause the display to present an indicia that is indicative of the velocity of the displacement member, wherein a portion of the display occupied by the indicia corresponds to the velocity of the displacement member.

Claims

1. A surgical instrument comprising:

a displacement member configured to translate within the surgical instrument;

a motor coupled to the displacement member to translate the displacement member;

a control circuit coupled to the motor;

a position sensor coupled to the control circuit, the position sensor configured to monitor a position of the displacement member; and

wherein the control circuit is configured to;

determine a velocity of the displacement member via the position sensor;

cause a display to present a mode indicia that is indicative of a mode of the surgical instrument, wherein the mode comprises an automatic mode and a manual mode; and

cause the display to present an indicia that is indicative of the velocity of the displacement member, wherein a portion of the display occupied by the indicia corresponds to the velocity of the displacement member,

wherein the indicia comprises a plurality of zones, each of the plurality of zones indicative of a velocity level.

2. The surgical instrument of claim 1, wherein the indicia is a first indicia, the control circuit is further configured to:

provide a set point velocity to the motor, the motor set point configured to cause the motor to drive the displacement member at a motor velocity; and

cause the display to present a second indicia indicative of the motor set point velocity.

4. The surgical instrument of claim 1, wherein the plurality of zones comprise a first zone indicative of a low velocity, a second zone indicative of a medium velocity, and a third zone indicative of a fast velocity.

3. (canceled)

5. A surgical instrument comprising:

a displacement member configured to translate within the surgical instrument;

a motor coupled to the displacement member to translate the displacement member;

a control circuit coupled to the motor;

a position sensor coupled to the control circuit, the position sensor configured to monitor a position of the displacement member; and

wherein the control circuit is configured to;

provide a motor set point to the motor, the motor set point configured to cause the motor to drive the displacement member at a velocity;

display an indicia on a display that is indicative of the velocity of the displacement member, wherein a portion of the display occupied by the indicia corresponds to the velocity of the displacement member; and

display a second indicia on the display that is indicative of the motor set point velocity.

6. The surgical instrument of claim 5, wherein the control circuit is further configured to cause the display to present a mode indicia that is indicative of a mode of the surgical instrument.

7. The surgical instrument of claim 6, wherein the mode comprises an automatic mode and a manual mode.

8. The surgical instrument of claim 5, wherein the control circuit is further configured to:

display an image representative of the displacement member; and

display progress of the image representative of the displacement member as the displacement member advances distally.

9. The surgical instrument of claim 5, wherein the second indicia represents a range of motor set point velocities.

10. The surgical instrument of claim 5, wherein the control circuit is further configured to display a status bar that represents operation status of the surgical instrument.

11. The surgical instrument of claim 10, wherein the status bar represents normal operation when the velocity of the displacement member is within a range of motor set point velocities.

12. The surgical instrument of claim 10, wherein the status bar represents cautionary operation when the velocity of the displacement member is outside a range of motor set point velocities.

13. The surgical instrument of claim 5, wherein the control circuit is further configured to:

monitor a condition of a battery; and

cause the display to present an image of a battery indicative of the condition of the battery.

14. A method of operating a surgical instrument, the surgical instrument comprising a displacement member configured to translate within the surgical instrument, a motor coupled to the displacement member to translate the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, the position sensor configured to monitor a position of the displacement member, the method comprising:
