  • Systems and methods for determining an end of life state for surgical devices
    Patent number: 11630427
    Abstract: The present disclosure is directed to systems and methods for determining an end of life state for an electromechanical surgical system. The system includes an end effector configured to perform at least one function and a shaft assembly being arranged for selectively interconnecting the end effector and a hand-held surgical instrument. The hand-held surgical instrument includes an instrument housing defining a connecting portion for selectively connecting with the shaft assembly. The hand-held surgical instrument also includes a motor assembly, a sensor array configured to obtain an operational parameter of the hand-held surgical instrument, and a controller configured to control operation of the hand-held surgical instrument based on the operational parameter obtained by the sensor array.
    Type: Grant
