Abstract
Technologies for operating an energy-based surgical instrument based on a tissue fingerprint includes generating an impedance fingerprint of patient tissue grasped within a jaw assembly of an end effector of the energy-based surgical instrument. The impedance fingerprint is indicative of an impedance response of the patient tissue to different amounts of clamp pressure on the patient tissue by the jaw assembly. Additionally, an operational characteristic of the energy-based surgical instrument may be adjusted as a function of the impedance fingerprint.
Claims23
A method for operating an energy-based surgical instrument, the method comprising:
- generating, by a controller of the energy-based surgical instrument, a tissue impedance fingerprint of patient tissue grasped within a jaw assembly of an end effector of the energy-based surgical instrument, wherein the tissue impedance fingerprint is indicative of an impedance response of the patient tissue to different amounts of clamp pressure on the patient tissue by the jaw assembly;
- adjusting, by the controller, an operational characteristic of the energy-based surgical instrument as a function of the tissue impedance fingerprint;
- and
- activating, by the controller, an operation of the energy-based surgical instrument using the adjusted operational characteristic.
An energy-based surgical instrument comprising:
- an end effector having a jaw assembly configured to grasp patient tissue;
- a clamp force sensor configured to generate sensor data indicative of an amount of clamp pressure applied by the jaw assembly on the patient tissue when the patient tissue is grasped by the jaw assembly;
- and
- a controller configured to:
- generate a tissue impedance fingerprint of the patient tissue, wherein the tissue impedance fingerprint is indicative of an impedance response of the patient tissue to different amounts of clamp pressure on the patient tissue by the jaw assembly;
- adjust an operational characteristic of the energy-based surgical instrument as a function of the tissue impedance fingerprint;
- and
- activate an operation of the energy-based surgical instrument using the adjusted operational characteristic.
