Abstract

Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

Claims21

Dependent claims

1-20. (canceled)

An apparatus, comprising:

(a) an end effector having a surgical feature;
(b) a generator connection;
(c) a user input configured to activate the surgical feature of the end effector;
(d) a memory configured to store a set of device life management characteristics;
and
(e) a processor configured to enable or disable the surgical feature based upon the set of device life management characteristics, wherein the processor is further configured to:
(A) determine a total generator connection time based upon the set of device life management characteristics, wherein the total generator connection time indicates a total duration of time that the end effector has been operatively connected to a generator,
(B) determine a total activation time based upon the set of device life management characteristics, wherein the total activation time indicates the total duration of time that the end effector has been in use,
(C) determine a usage ratio of the total generator connection time to the total activation time, and
(D) disable the surgical feature when the usage ratio exceeds an upper abnormal use threshold or when the usage ratio is below a lower abnormal use threshold.
