MANAGING TISSUE TREATMENT

摘要

Various embodiments are directed to systems and methods for providing a drive signal to a surgical device for treating tissue. A surgical generator may deliver the drive signal according to a first composite load curve. The surgical generator may receive a first tissue measurement indicating a property of the tissue at a first time during the delivery of the drive signal, receive a second tissue measurement indicating the property of the tissue at a second time during the delivery of the drive signal after the first time, and based on the first and second tissue measurements, determine a difference in the property of the tissue between the first time and the second time. When the difference in the property of the tissue exceeds a difference threshold, the generator may deliver the drive signal according to a second composite load curve that is more aggressive than the first composite load curve.

1. A surgical system for providing a drive signal to a surgical device for treating tissue, the surgical system comprising:
a surgical generator, wherein the surgical generator is programmed to:
deliver the drive signal according to a first composite load curve, wherein the first composite load curve defines a first level of power to be delivered to the tissue as a function of at least one measured property of the tissue, and wherein the first composite load curve defines a plurality of pulses to be sequentially applied to the drive signal;receive a first tissue measurement indicating a property of the tissue at a first time during the delivery of the drive signal;receive a second tissue measurement indicating the property of the tissue at a second time during the delivery of the drive signal, wherein the second time is after the first time;based on the first and second tissue measurements, determine a difference in the property of the tissue between the first time and the second time;when the difference in the property of the tissue exceeds a difference threshold, deliver the drive signal according to a second composite load curve, wherein the second composite load curve is more aggressive than the first composite load curve.
