International Classification:

A61B 18/12
A61B 17/32
H01L 41/04

Abstract:

A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

International Classification:

A61N 7/00
A61N 7/02
A61B 18/14
G05B 15/02
B06B 1/02

Abstract:

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.

International Classification:

A61B 18/12
A61B 17/32
H01L 41/04

Abstract:

A control circuit configured to receive a control signal that defines a first phase and a second phase from a surgical generator. The control circuit may include a first resistor, a second resistor in parallel with the first resistor, and a switch in series with the second resistor. The switch may be configured to transition between an open state and a closed state corresponding to an operational mode of a surgical instrument. In the first phase of the control signal, the control circuit is configured to communicate surgical instrument information to the surgical generator. In the second phase of the control signal and in the open state of the switch, the control circuit is configured to provide a first output. In the second phase of the control signal and in the closed state of the switch, the control circuit is configured to provide a second output.
