| 摘要 |
Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. The method comprises generating at least one electrical signal. The at least one electrical signal is monitored against a first set of logic conditions. A first response is triggered when the first set of logic conditions is met. A parameter is determined from the at least one electrical signal. |

1. A method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument, the method comprising:
generating, by a generator, at least one electrical signal; monitoring the at least one electrical signal against a first set of logic conditions; triggering a first response of the generator when the first set of logic conditions is met; determining, from the at least one electrical signal, a parameter associated with the surgical instrument, the determined parameter being a rate of temperature change of the end effector assessed by calculating a frequency slope; and comparing the frequency slope against a predetermined threshold. |
