摘要
A method for assessing performance of a surgical instrument including one or more drivetrains is disclosed. The method includes sensing via one or more vibration sensors vibrations generated during operation of the one or more drivetrains of the surgical instrument, generating an output signal based on the sensed vibrations, filtering the output signal to generate a filtered signal of the sensed vibrations from the one or more drivetrains, processing the filtered signal to generate a processed signal of the sensed vibrations from the one or more drivetrains, and comparing predetermined threshold values for each of an acceptable status, a marginal status, and a critical status of the surgical instrument to corresponding values of the processed signal.
