Abstract

An electrosurgical generator is disclosed. The generator includes an output stage configured to generate a waveform, a first input configured to adjust a cut setting representative of a cutting effect of the waveform, and a second input configured to adjust a hemostasis setting representative of a hemostasis effect of the waveform. The generator also includes a controller configured to receive cut and hemostasis settings and to adjust one of a duty cycle, a crest factor and a power level of the waveform to achieve a combined cutting and hemostasis effect based on the cut and hemostasis settings.

Claims

1. An electrosurgical generator, comprising:

an output stage configured to generate a waveform suitable to simultaneously impart a cutting effect and hemostasis effect on tissue;

a first input configured to adjust a cut setting representative of the cutting effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the hemostasis effect;

a second input configured to adjust a hemostasis setting representative of the hemostasis effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the cutting effect; and

a controller configured to receive the cut and hemostasis settings in real time and adjust at least one of a duty cycle, a crest factor and a power level of the waveform to achieve the simultaneous cutting and hemostasis effects based on the cut and hemostasis settings, the cut and hemostasis settings being adjustable to independently adjust each of the cutting and hemostasis effects imparted by the waveform.

2. The electrosurgical generator according to claim 1, wherein the waveform is selected from a group consisting of an RF electrosurgical waveform and a microwave waveform.

3. The electrosurgical generator according to claim 1, further comprising:

at least one display screen configured to output the cut setting and the hemostasis setting.

4. The electrosurgical generator according to claim 3, wherein the at least one display screen is a touch screen.

5. The electrosurgical generator according to claim 4, wherein the at least one display screen is configured to output a user interface including the first and second inputs.

6. The electrosurgical generator according to claim 3, wherein each of the cut and hemostasis settings displays a scale representative of the cutting effect and the hemostasis effect of the waveform, respectively.

7. The electrosurgical generator according to claim 6, wherein the displayed scale of the cut setting represents a rate of the cutting effect and the displayed scale of the hemostasis setting represents a thickness of the hemostasis effect.

8. A method for controlling an electrosurgical generator, the method comprising the steps of:

outputting a waveform suitable to simultaneously impart a cutting effect and hemostasis effect on tissue;

adjusting a cut setting representative of the cutting effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the hemostasis effect;

adjusting a hemostasis setting representative of the hemostasis effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the cutting effect; and

adjusting at least one waveform parameter of the waveform to achieve the simultaneous cutting and hemostasis effects based on the cut and hemostasis settings, the cut and hemostasis settings being adjustable to independently adjust each of the cutting and hemostasis effects of the waveform.

9. The method according to claim 8, wherein the at least one waveform parameter is selected from a group consisting of a duty cycle, a crest factor and a power level.

10. The method according to claim 8, further comprising the step of:

displaying the cut setting and the hemostasis setting on at least one display screen including a touch screen.

11. The method according to claim 10, further comprising the step of:

outputting a user interface including a first input configured to adjust the cut setting and a second input configured to adjust the hemostasis setting on the at least one display screen.

12. The method according to claim 10, wherein the displaying step further includes the step of displaying each of the cut and hemostasis settings as a scale representative of the cutting effect and the hemostasis effect of the waveform, respectively.

13. An electrosurgical system, comprising:

an electrosurgical generator, comprising;

an output stage configured to generate a waveform suitable to simultaneously impart a cutting effect and a hemostasis effect on tissue;

a first input configured to adjust a cut setting representative of the cutting effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the hemostasis effect;

a second input configured to adjust a hemostasis setting representative of the hemostasis effect of the waveform in real time during the simultaneous imparting of the cutting and hemostasis effects on the tissue without changing the cutting effect; and

a controller configured to receive the cut and hemostasis settings in real time and adjust at least one parameter of the waveform to achieve the simultaneous cutting and hemostasis effects based on the cut and hemostasis settings, the cut and hemostasis settings being adjustable to independently adjust each of the cutting and hemostasis effects imparted by the waveform; and

at least one electrosurgical instrument configured to couple to the electrosurgical generator and to supply the waveform to the tissue.

14. The electrosurgical system according to claim 13, wherein the at least one parameter is selected from a group consisting of a duty cycle, a crest factor and a power level.

15. The electrosurgical system according to claim 13, further comprising:

at least one display screen configured to output the cut setting and the hemostasis setting.

16. The electrosurgical system according to claim 15, wherein the at least one display screen is a touch screen.

17. The electrosurgical system according to claim 16, wherein the at least one display screen is configured to output a user interface including the first and second inputs.

18. The electrosurgical system according to claim 15, wherein each of the cut and hemostasis settings displays a scale representative of the cutting effect and the hemostasis effect of the waveform, respectively.

19. The electrosurgical generator according to claim 18, wherein the displayed scale of the cut setting represents a rate of the cutting effect and the displayed scale of the hemostasis setting represents a thickness of the hemostasis effect.

20. The electrosurgical generator according to claim 13, wherein the waveform is selected from a group consisting of an RF electrosurgical waveform and a microwave waveform.
