Abstract

A surgical method is provided, comprising: providing an information structure in a computer readable storage device that associates an indication of surgeon skill level in at least one surgical activity performed using the surgical instrument with a surgical instrument actuator safety state of the surgical instrument for use during performance of the at least one surgical activity using the surgical instrument by a surgeon having the indicated skill level; tracking surgical instrument actuator state of a surgical instrument during performance of a surgical procedure by a surgeon; and transitioning the surgical instrument actuator state of the surgical instrument to the surgical instrument safety state during performance of the at least one surgical activity by the surgeon using the surgical instrument.

First claim

What is claimed is:

1 . A method comprising:
identifying, by one or more processors of a surgical system, an information structure that associates each of a plurality of actuator states of a surgical instrument of the surgical system with a decrement count of a remaining lifetime of the surgical instrument, wherein one or more of the plurality of actuator states are associated with different decrement counts; determining, by the one or more processors, that the surgical instrument is operating during surgery in an actuator state of the plurality of actuator states of the surgical instrument; identifying, by the one or more processors from the information structure, the decrement count for the actuator state; and adjusting, by the one or more processors using the decrement count, the remaining lifetime of the surgical instructions.

2 . The method of claim 1 , further comprising determining, by the one or more processors, that the surgical instrument is operating during surgery in a second actuator state of the plurality of actuator states of the surgical instrument.

3 . The method of claim 2 , further comprising adjusting, by the one or more processors, the remaining lifetime of the surgical instructions using a second decrement count associated with the second actuator state in the information structure.

4 . The method of claim 1 , further comprising determining, by the one or more processors, that the surgical instrument had a sterilization event.

5 . The method of claim 4 , further comprising determining, by the one or more processors responsive to the sterilization event, an adjustment to the remaining lifetime of the surgical instrument based at least on the type of the surgical instrument.

6 . The method of claim 1 , wherein the information structure is further configured to associate the one or more actuator states of the plurality of actuator states and one or more activities of the plurality of activities of the surgical instrument with one or more decrement counts of the remaining lifetime of the surgical instrument.

7 . The method of claim 6 , further comprising receiving, by the one or more processors, an indication of an activity of the plurality of activities of the surgical instrument during surgery.

8 . The method of claim 7 , further comprising identifying, by the one or more processors from the information structure, the decrement count for both the actuator state and the activity.

9 . A surgical system comprising:
one or more processors, coupled to memory, to: identify an information structure in the memory that associates each of a plurality of actuator states of a surgical instrument of the surgical system with a decrement count of a remaining lifetime of the surgical instrument, wherein one or more of the plurality of actuator states are associated with different decrement counts; determine that the surgical instrument is in an actuator state of the plurality of actuator states of the surgical instrument during a surgery; identify, from the information structure, the decrement count for the actuator state; and adjust the remaining lifetime of the surgical instructions using the decrement count.

10 . The surgical system of claim 9 , wherein the one or more processors are further configured to determine that the surgical instrument is in a second actuator state of the plurality of actuator states of the surgical instrument during surgery.

11 . The surgical system of claim 10 , wherein the one or more processors are further configured to adjust the remaining lifetime of the surgical instructions using a second decrement count associated with the second actuator state in the information structure.

12 . The surgical system of claim 9 , wherein the one or more processors are further configured to determine that the surgical instrument had a sterilization event.

13 . The surgical system of claim 12 , wherein the one or more processors are further configured to determine, responsive to the sterilization event, an adjustment to the remaining lifetime of the surgical instrument based at least on the type of the surgical instrument.

14 . The surgical system of claim 9 , wherein the one or more processors are further configured to associate the one or more actuator states of the plurality of actuator states and one or more activities of the plurality of activities of the surgical instrument with one or more decrement counts of the remaining lifetime of the surgical instrument.

15 . The surgical system of claim 9 , wherein the one or more processors are further configured to receive an indication of an activity of the plurality of activities of the surgical instrument during surgery and identify from the information structure the decrement count for both the actuator state and the activity.

16 . A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a surgical system, cause the one or more processors to:
identify an information structure that associates each of a plurality of actuator states of a surgical instrument of the surgical system with a surgical activity of a plurality of surgical activities and a decrement count of a remaining lifetime of the surgical instrument, wherein one or more of the plurality of actuator states have different decrement counts; determine that the surgical instrument is in an actuator state of the plurality of actuator states of the surgical instrument during a surgical activity of the plurality of surgical activities; identify from the information structure, the decrement count for the actuator state and the surgical activity; and adjust the remaining lifetime of the surgical instructions using the decrement count.

17 . The non-transitory computer-readable medium of claim 16 , further comprising instructions that, when executed by one or more processors of the surgical system, cause the one or more processors to:
determine that the surgical instrument is in a second actuator state of the plurality of actuator states of the surgical instrument during surgery.

18 . The non-transitory computer-readable medium of claim 17 , further comprising instructions that, when executed by one or more processors of the surgical system, cause the one or more processors of the surgical system to: adjust the remaining lifetime of the surgical instructions using a second decrement count associated with the second actuator state in the information structure.

19 . The non-transitory computer-readable medium of claim 17 , further comprising instructions that, when executed by one or more processors of the surgical system, cause the one or more processors of the surgical system to: determine that the surgical instrument had a sterilization event.

20 . The non-transitory computer-readable medium of claim 17 , further comprising instructions that, when executed by one or more processors of the surgical system, cause the one or more processors of the surgical system to: determine an adjustment to the remaining lifetime of the surgical instrument based at least on the type of the surgical instrument.
