Abstract

A surgical instrument includes an end effector having first and second jaws that cooperate to capture tissue therebetween, a movable firing member to cut the tissue, an actuator actuatable between various settings that define various output values of a characteristic of motion of the firing member, and a real-time feedback system. The real-time feedback system includes a sensor to assess a parameter of the end effector, a zone indicator adjustable between various positions inside and outside a desired zone, and a circuit to receive the sensor input from the sensor, the sensor input defining a measurement of a parameter of the end effector, and select one of various positions based upon the measurement of the parameter of the end effector, the selected position representing a status of a current output value of the characteristic of motion of the firing member, and adjust the zone indicator to the selected position.

Claims

1. A surgical instrument, comprising:

an end effector, comprising;

a first jaw; and

a second jaw, wherein the first jaw and the second jaw cooperate to capture tissue therebetween;

a firing member movable to cut the captured tissue;

an actuator actuatable between a plurality of settings, wherein the plurality of settings define a plurality of output values of a characteristic of motion of the firing member; and

a real-time feedback system, comprising;

at least one sensor configured to assess at least one parameter of the end effector;

a zone indicator adjustable between a plurality of positions inside and outside a desired zone; and

a circuit configured to;

receive at least one sensor input from the at least one sensor, wherein the at least one sensor input defines at least one measurement of the at least one parameter of the end effector;

select one of the plurality of positions based upon the at least one measurement of the at least one parameter of the end effector, wherein the selected one of the plurality of positions represents a status of a current output value of the characteristic of motion of the firing member; and

adjust the zone indicator to the selected one of the plurality of positions.

2. The surgical instrument of claim 1, wherein the at least one parameter comprises a distance between the first jaw and the second jaw.

3. The surgical instrument of claim 1, wherein the at least one parameter comprises a compression level of the captured tissue.

4. The surgical instrument of claim 1, wherein the at least one parameter comprises a force required to advance the firing member.

5. The surgical instrument of claim 1, wherein the plurality of positions comprises at least two positions inside the desired zone.

6. The surgical instrument of claim 1, wherein the plurality of positions comprises at least one position inside the desired zone and at least one position outside the desired zone.

7. The surgical instrument of claim 1, wherein the characteristic of motion is a velocity of the firing member.

8. The surgical instrument of claim 1, further comprising a tacking system configured to determine a current setting of the actuator.

9. A surgical instrument, comprising:

an end effector configured to capture tissue; and

a real time feedback system, comprising;

at least one sensor configured to assess at least one parameter of the end effector

a zone indicator adjustable between a plurality of positions inside and outside a desired zone; and

a circuit configured to;

receive at least one sensor input from the at least one sensor, wherein the at least one sensor input defines at least one measurement of the at least one parameter of the end effector;

assess a manual input;

select one of the plurality of positions based upon the at least one measurement of the at least one parameter of the end effector, wherein the selected one of the plurality of positions characterizes the manual input with respect to the desired zone; and

adjust the zone indicator to the selected one of the plurality of positions.

10. The surgical instrument of claim 9, wherein the at least one parameter comprises a distance between the first jaw and the second jaw.

11. The surgical instrument of claim 9, wherein the at least one parameter comprises a compression level of the captured tissue.

12. The surgical instrument of claim 9, wherein the at least one parameter comprises a force required to advance the firing member.

a second jaw, wherein the first jaw and the second jaw cooperate to capture tissue therebetween;

a firing member movable to cut the captured tissue;

an actuator actuatable between a plurality of settings; and

a real time feedback system, comprising;

at least one sensor configured to assess at least one parameter of the end effector;

a processor; and

a memory that stores program instructions, which when executed from the memory cause the processor to;

receive at least one sensor input from the at least one sensor, wherein the at least one sensor input defines at least one measurement of the at least one parameter of the end effector;

determine a value representing a current setting of the plurality of settings of the actuator;

assign a rank to the value with respect to a desired range, wherein the rank is based upon the value and the at least one measurement of the at least one parameter of the end effector; and

report the rank.

17. The surgical instrument of claim 16, wherein the at least one parameter comprises a distance between the first jaw and the second jaw.

18. The surgical instrument of claim 16, wherein the at least one parameter comprises a compression level of the captured tissue.
