Abstract

An ultrasonic surgical system is provided. The ultrasonic surgical system includes an ultrasonic instrument that is configured to ultrasonically treat tissue. An ultrasonic generator configured to provide ultrasonic energy to the ultrasonic instrument provides an indication to a user that a specific outcome has been achieved. The indication is output via a device selected from an audio activation end-tone device, a visual activation end-tone device or a tactile activation end-tone device. The ultrasonic generator includes an end-tone outcome indicator module that includes memory having one or more data look up tables that is accessible by a microprocessor associated with the ultrasonic generator.

Claims

1. An ultrasonic surgical system, comprising:

an ultrasonic instrument configured to ultrasonically treat tissue, the ultrasonic instrument including at least one indicator operably disposed thereon;

an ultrasonic generator in communication with the ultrasonic instrument and configured to provide ultrasonic energy thereto; and

an outcome indicator module included within the ultrasonic generator and configured, for each of first, second, and third specific tissue-effect outcomes for respective first, second, and third tissue sizes of vessels ranging from 1 mm-2 mm, from 2 mm-5 mm, and from 5 mm-7 mm, respectively, to control the at least one indicator to provide;

(1) a changing indication that the specific tissue-effect outcome for the tissue size is being achieved; and

(2) a second indication that the specific tissue-effect outcome for the tissue size has been achieved, the outcome indicator module including at least one data look up table including empirical data including at least one predetermined time value that corresponds to a maximum value obtained for the specific tissue-effect outcome for the tissue size, wherein the outcome indicator module is programmed to track progression of the specific tissue-effect outcome for the tissue size along a graph of the empirical data and provide an indication for a duration that the progression of the specific tissue-effect outcome for the tissue size is being tracked along the graph of the empirical data,

the at least one indicator configured to receive the changing indication and the second indication from the outcome indicator module and provide an output to a user of the changing indication and the second indication, the output provided via the at least one indicator operably disposed on the ultrasonic instrument,

wherein the changing indication begins at a first indication and transitions to the second indication, and

wherein the specific tissue-effect outcome for the tissue size is burst pressure or thermal spread.

2. The ultrasonic surgical system according to claim 1, wherein the outcome indicator module includes a memory having at least one data look up table that is accessible by a microprocessor associated with the ultrasonic generator.

3. A method for performing a surgical procedure, comprising:

grasping tissue with an ultrasonic instrument;

delivering ultrasonic energy via an ultrasonic generator to the ultrasonic instrument;

tracking progression of a first specific tissue-effect outcome, a second specific tissue-effect outcome, and a third specific tissue-effect outcome along a graph of empirical data including first, second, and third predetermined times obtained for respective vessels ranging from 1 mm-2 mm, from 2 mm-5 mm, and from 5 mm-7 mm, the first, second, and third predetermined times corresponding to first, second, and third maximum values obtained for each of the first specific tissue-effect outcome, the second specific tissue-effect outcome, and the third specific tissue-effect outcome;

providing a changing indication of the first specific tissue-effect outcome indicating that the first specific tissue-effect outcome is being achieved, wherein the changing indication of the first specific tissue-effect outcome begins at a first indication of the first specific tissue-effect outcome and transitions to a second indication of the first specific tissue-effect outcome;

providing the second indication of the first specific tissue-effect outcome indicating that the first specific tissue-effect outcome has been achieved;

providing a second changing indication of the second specific tissue-effect outcome indicating that the second specific tissue-effect outcome is being achieved, wherein the second changing indication of the second specific tissue-effect outcome begins at a first indication of the second specific tissue-effect outcome and transitions to a second indication of the second specific tissue-effect outcome;

providing the second indication of the second specific tissue-effect outcome indicating that the second specific tissue-effect outcome has been achieved;

providing a third changing indication of the third specific tissue-effect outcome indicating that the third specific tissue-effect outcome is being achieved, wherein the third changing indication of the third specific tissue-effect outcome begins at a first indication of the third specific tissue-effect outcome and transitions to a second indication of the third specific tissue-effect outcome;

providing the second indication of the third specific tissue-effect outcome indicating that the third specific tissue-effect outcome has been achieved; and

outputting the changing indication of the first specific tissue-effect outcome, the second indication of the first specific tissue-effect outcome, the second changing indication of the second specific tissue-effect outcome, the second indication of the second specific tissue-effect outcome, the third changing indication of the third specific tissue-effect outcome, and the second indication of the third specific tissue-effect outcome,

wherein the outputting is provided via an indicator operably disposed on the ultrasonic instrument, and

wherein at least one of the first specific tissue-effect outcome, the second specific tissue-effect outcome, or the third specific tissue-effect outcome is burst pressure or thermal spread.

4. The method according to claim 3, wherein the ultrasonic generator includes an outcome indicator module including memory having at least one data look up table that is accessible by a microprocessor associated with the ultrasonic generator.
