Electrosurgical forceps with tissue resonance detection

A system for treating tissue, comprising:

• a surgical forceps including a housing having an elongated shaft extending distally therefrom and an end effector assembly coupled to a distal end thereof, the end effector assembly including a first jaw member and a second jaw member with a respective first tissue sealing plate and a second tissue sealing plate;
• a generator configured to supply electrosurgical energy to the first and second tissue sealing plates;
• and
• a sensor disposed on the first tissue sealing plate or the second tissue sealing plate and configured to communicate data relating to grasped tissue between the first jaw member and the second jaw member for:
• determining a resonance frequency of the grasped tissue;
• and
• based on the determined resonance frequency, adjusting one or more parameters associated with delivery of electrosurgical energy to the tissue.

A system for treating tissue, comprising:

• an electrosurgical instrument comprising an end effector coupled to an elongated shaft, the end effector comprising a first jaw member and a second jaw member with a respective first tissue sealing plate and a second tissue sealing plate;
• one or more sensors disposed on the first tissue sealing plate or the second tissue sealing plate, the one or more sensors configured to communicate data relating to grasped tissue between the first jaw member and the second jaw member;
• and
• a generator coupled to the electrosurgical instrument and communicatively coupled to the one or more sensors, the generator configured to:
• determine, based on the data from the one or more sensors, a resonance frequency of the grasped tissue;
• identify, based on the determined resonance frequency, a critical structure present within the grasped tissue;
• and
• based on the identified critical structure, at least one of:
• provide an indication for a clinician to reposition the end effector, or
• deactivate a supply of power to the electrosurgical instrument.
