14. The telesurgical system of claim 1 , wherein:

updating the remaining usable life value comprises updating the remaining usable life value at least based on a number of surgical procedures in which the surgical instrument is used.

15. A medical device comprising:

a surgical instrument comprising a distal end component and an actuation component coupled to move the distal end component; and

a control system configured to execute instructions to perform operations comprising:

determining a remaining usable life value of the surgical instrument before a use of the surgical instrument,

monitoring an amount of use of the actuation component during the use of the surgical instrument, wherein monitoring the amount of use of the actuation component comprises determining the amount of use of the actuation component based on a force or torque on the actuation component, and

updating the remaining usable life value to an updated usable life value of the surgical instrument based at least on the amount of use of the actuation component during the use of the surgical instrument.

16. The medical device of claim 15 , wherein:

updating the remaining usable life value comprises one of:

updating the remaining usable life value to a first remaining usable life value based on a first amount of use of the actuation component during the use of the surgical instrument, or updating the remaining usable life value to a second remaining usable life value based on a second amount of use of the actuation component during the use of the surgical instrument;

the second amount of use of the actuation component is different from the first amount of use; and

the second remaining usable life value is different from the first remaining usable life value.

17. The medical device of claim 15 , wherein:

the operations further comprise preventing further use of the surgical instrument based on the updated remaining usable life value of the surgical instrument.

18. The medical device of claim 17 , wherein:

the use of the surgical instrument occurs during a first surgical procedure; and

preventing further use of the surgical instrument based on the updated remaining usable life value of the surgical instrument comprises preventing the further use of the surgical instrument during a second surgical procedure subsequent to the first surgical procedure.
