MECHANISMS FOR COMPENSATING FOR DRIVETRAIN FAILURE IN POWERED SURGICAL INSTRUMENTS
First Claim
1. A surgical apparatus, comprising:
- an end effector configured to interact with a tissue; and
a surgical instrument, comprising;
at least one drive mechanism operable to effect at least one motion in the end effector; and
one or more vibration sensors configured to record vibrations generated by the at least one drive mechanism, wherein the one or more vibration sensors are configured to generate an output signal based on the sensed vibrations, and wherein the output signal is employed to select between an acceptable status, a marginal status, and a critical status of the surgical instrument.

Abstract
A surgical apparatus includes an end effector configured to interact with a tissue and a surgical instrument. The surgical instrument includes at least one drive mechanism operable to effect at least one motion in the end effector. The surgical instrument further includes one or more vibration sensors configured to record vibrations generated by the at least one drive mechanism, wherein the one or more vibration sensors are configured to generate an output signal based on the sensed vibrations, and wherein the output signal is employed to select between an acceptable status, a marginal status, and a critical status of the surgical instrument.

12. A method for assessing performance of a surgical instrument including one or more drivetrains, the method comprising:
-
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. - View Dependent Claims (13, 14, 15, 16, 17)

18. A surgical stapler, comprising:
-
a staple cartridge comprising a plurality of staples deployable into tissue; at least one drive mechanism operable to deploy the plurality of staples into the tissue during a firing sequence of the surgical stapler; and one or more vibration sensors configured to record vibrations generated by the at least one drive mechanism, wherein the one or more vibration sensors are configured to generate an output signal based on the sensed vibrations, and wherein the output signal is employed to select between an acceptable status, a marginal status, and a critical status of the at least one drive mechanism. - View Dependent Claims (19, 20)
