Title: POWERED SURGICAL TOOL WITH PREDEFINED ADJUSTABLE CONTROL ALGORITHM FOR CONTROLLING END EFFECTOR PARAMETER
Abstract: A surgical system is disclosed. The surgical system comprises a surgical instrument comprising an end effector, wherein the end effector is configured to perform an end effector function, and a control circuit configured to control the end effector function and automatically adapt the control of the end effector function over time, and limit the automatic adaptation of the control of the end effector function.

Claims: number: 1
text: A surgical system, comprising:
number: 2
text: The surgical system of claim 1, the control circuit further configured to receive information about a sensed parameter, wherein the control circuit is configured to adapt the control of the end effector function over time based on the sensed parameter.
number: 3
text: The surgical system of Claim 1, wherein the control circuit is further configured to automatically adapt the control of the end effector function.
number: 4
text: The surgical system of Claim 3, wherein the control circuit is further configured to automatically adapt the control of the end effector function.using machine learning.
number: 5
text: The surgical system of Claim 3 or Claim 4, wherein the automatic adaptation is dependent on a sensed parameter in the surgical instrument.
number: 6
text: The surgical system of Claim 2 or Claim 5, wherein the sensed parameter comprises a set of previously-sensed parameters from previous uses of the surgical instrument.
number: 7
text: The surgical system of Claim 6, wherein the set of previously-sensed parameters comprises parameters sensed during uses of the surgical instrument by a specific user.
number: 8
text: The surgical system of Claim 6 or Claim 7, wherein the set of previously-sensed parameters comprises parameters sensed during uses of the surgical instrument in a specific location.
number: 9
text: The surgical system of any of Claims 2 to 8, wherein the control circuit is further configured to limit the automatic adaptation of the control of the end effector function to a specific range of adjustments.
number: 10
text: The surgical system of Claim 9, wherein the specific range of adjustments is predefined.
number: 11
text: The surgical system of Claim 9 or Claim 10, wherein the specific range of adjustments is manually adjustable.
number: 12
text: The surgical system of any one of Claims 9 to 11, wherein the specific range of adjustments is automatically adjusted by the control circuit based on machine learning.
number: 13
text: The surgical system of any one of Claims 2 to 12, wherein the control circuit is further configured to limit the automatic adaptation of the control of the end effector function to a maximum threshold adjustment.
number: 14
text: The surgical system of any preceding Claim, wherein limiting the automatic adaptation of the control of the end effector function is based on a per-use basis.
number: 15
text: The surgical system of any preceding Claim, wherein limiting the automatic adaptation of the control of the end effector function is based on a specific user.
number: 16
text: The surgical system of preceding Claim, wherein the limiting the automatic adaptation of the control of the end effector function is based on a specific location of the surgical instrument.
number: 17
text: A surgical system, comprising:
number: 18
text: The surgical system of Claim 17, wherein the control circuit is configured to automatically adjust the control of the parameter using machine learning.
number: 19
text: The surgical system of Claim 17 or Claim 18, wherein the adjustability window is manually selectable by a clinician.
number: 20
text: The surgical system of any one of Claims 15 to 19, wherein the adjustability window is automatically selected based on machine learning.
number: 21
text: The surgical system of Claim 20, wherein limiting the adaptation of the control of the end effector function comprises limiting the adaptation of the control of the end effector function to a range of adaptability.
