Abstract
A method for coagulating and dissecting tissue. The method includes measuring a tissue property and delivering multiple energy modalities to the tissue based on the tissue property. The energy modalities being delivered from a generator either alone or in combination.
Claims22
A method comprising:
- delivering, by a first drive circuit, a first energy modality to an end effector of a surgical instrument interacting with tissue;
- determining, by a processor, a tissue parameter of the tissue interacting with the end effector;
- comparing, by the processor, the determined tissue parameter with a threshold value of the tissue parameter;
- and
- delivering, by a drive circuit, a second energy modality to the end effector when the determined tissue parameter is greater than or equal to the threshold value of the tissue parameter;
- wherein the first energy modality is different from the second energy modality.

A method comprising:
- delivering, by a drive circuit, a first drive signal to an end effector of a surgical instrument at an amplitude;
- measuring, by a processor, a tissue parameter of tissue engaged with the end effector;
- modulating, by the processor, delivery of the first drive signal based on the measured tissue parameter;
- and
- ceasing, by the processor, delivery of the first drive signal when a termination parameter is met.
2 more elements
A method comprising:
- calculating, by a processor, a tissue parameter of tissue engaged with an end effector of a surgical instrument;
- comparing, by the processor, the calculated tissue parameter with a threshold impedance value;
- delivering, by an RF drive circuit, RF energy to an electrode of the end effector when the calculated tissue parameter is less than the threshold value of the tissue parameter;
- and
- delivering, by an ultrasonic drive circuit, ultrasonic energy to an ultrasonic blade of the end effector when the calculated tissue parameter is greater than or equal to the threshold value of the tissue parameter.
