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; and

an ultrasonic generator configured to provide ultrasonic energy to the ultrasonic instrument and provide an indication to a user that a specific outcome has been achieved,

wherein the indication is output via a device selected from the group consisting of an audio activation end-tone device, a visual activation end-tone device and a tactile activation end-tone device and wherein the ultrasonic generator includes an end-tone outcome indicator module including memory having at least one data look up table that is accessible by a microprocessor associated with the ultrasonic generator.

2. An ultrasonic surgical system according to claim 1, wherein at least one of the audio activation end-tone device, a visual activation end-tone device and a tactile activation end-tone device is operably disposed on the ultrasonic instrument.

3. An ultrasonic surgical system according to claim 1, wherein the indication is provided to the user to indicate that an outcome representative of a low end of thermal spread has been achieved with a minimum burst pressure of about equal to systolic blood pressure.

4. An ultrasonic surgical system according to claim 1, wherein the indication is provided to the user to indicate that an outcome representative of correct pressure for a given energy setting on the ultrasonic generator has been achieved to optimize dissection speed.

5. An ultrasonic surgical system, comprising:

an ultrasonic instrument configured to ultrasonically treat tissue, the ultrasonic instrument including at least one end-tone indication device thereon; and

an ultrasonic generator in operable communication with the ultrasonic instrument and configured to provide ultrasonic energy thereto, the ultrasonic generator including an end-tone outcome indicator module operable to control the at least one end-tone indication device to provide an indication to a user that a specific outcome relating to the tissue has been achieved.

6. An ultrasonic surgical system according to claim 5, wherein the at least one end-tone indication device is selected from the group consisting of an audio activation end-tone device, a visual activation end-tone device and a tactile activation end-tone device.

7. An ultrasonic surgical system according to claim 5, wherein the end-tone outcome indicator module includes memory having at least one data look up table that is accessible by a microprocessor associated with the ultrasonic generator.

8. An ultrasonic surgical system according to claim 5, wherein the indication is provided to the user to indicate that an outcome representative of when a low end of thermal spread has been achieved with a minimum burst pressure of about equal to systolic blood pressure.

9. An ultrasonic surgical system according to claim 5, wherein the indication is provided to the user to indicate that an outcome representative of correct pressure for a given energy setting on the ultrasonic generator has been achieved to optimize dissection speed.

10. A method for performing an ultrasonic procedure, comprising:
