Abstract

Various exemplary methods, systems, and devices for controlling electrosurgical tools are provided. A surgical system includes a drive system, the drive system being configured to drive the application of energy, an electrosurgical generator; and a control system configured to be operatively coupled to the drive system. The control system is configured to receive energy from the generator, deliver the received energy from the generator to the drive system, receive first impedance data via the drive system, manipulate the first impedance data to create second impedance data that is modified from the first impedance data, and transmit the second impedance data to the generator to cause the generator to deliver energy to the control system within predefined power parameters of the generator that define a maximum amount of energy the generator can deliver to the control system.

Claims (29)

1. A surgical system, comprising:

a drive system configured to be removably and replaceably operatively coupled to a surgical tool configured to apply energy to tissue clamped by the surgical tool, the drive system being configured to drive the application of energy;

an electrosurgical generator; and

a control system configured to be operatively coupled to the drive system, and the control system being configured to:

receive energy from the generator,

deliver the received energy from the generator to the drive system to drive the application of energy,

receive first impedance data via the drive system related to the application of the energy from the surgical tool to the tissue,

manipulate the first impedance data through a pair of transformers in parallel between the electrosurgical generator and the drive system to create second impedance data that is modified from the first impedance data, and

transmit the second impedance data to the generator to cause the generator to deliver energy to the control system within predefined power parameters of the generator that define a maximum amount of energy the generator can deliver to the control system;

wherein transmitting the first impedance data to the generator would prevent the generator from delivering energy to the control system as being outside the predefined power parameters of the generator.

2. The surgical system of claim 1 , wherein the first impedance data includes impedance of the tissue clamped by the surgical tool.

3. The surgical system of claim 2 , wherein the manipulation of the first impedance data includes processing with a processor the first impedance data through the pair of transformers.

4. The surgical system of claim 1 , wherein the drive system includes at least one motor configured to drive the surgical tool removably and replaceably operatively coupled to the drive system to drive the application of energy.

5. The surgical system of claim 1 , wherein a robotic surgical system includes the drive system and the control system.

6. The surgical system of claim 1 , wherein the surgical tool includes first and second jaws configured to clamp the tissue, each of the first and second jaws having at least one electrode thereon that is configured to apply the energy to the clamped tissue.

7. The surgical system of claim 1 , wherein the energy is radiofrequency energy.

8. A surgical system, comprising:

an electrosurgical generator having predefined power parameters that define a maximum amount of energy the generator can deliver therefrom; and

a control system configured to be operatively coupled to a surgical tool configured to apply energy to tissue clamped by the surgical tool, and the control system being configured to:

receive impedance data that is indicative of an impedance of tissue that is clamped by the surgical tool,

transform the received impedance data through a pair of transformers in parallel between the electrosurgical generator and the surgical tool,

transmit the transformed impedance data to the generator so as to activate the generator into delivering energy to the control system because transmission of the untransformed impedance data to the generator prevents the generator from delivering energy to the control system as being outside of the predefined power parameters of the generator,

after transmitting the transformed impedance data, receive energy from the generator, and

deliver the received energy to the surgical tool to allow the surgical tool to apply energy to the clamped tissue.

9. The surgical system of claim 8 , wherein transforming the received impedance data includes processing with a processor the received impedance data through the pair of transformers.

10. The surgical system of claim 8 , further comprising a drive system configured to drive the application of energy in response to control from the control system, wherein the drive system is configured to operatively couple to the surgical tool, and the drive system includes at least one motor configured to drive the surgical tool removably and replaceably operatively coupled to the drive system to drive the application of energy.

11. The surgical system of claim 10 , wherein a robotic surgical system includes the drive system and the control system.

12. The surgical system of claim 8 , wherein the surgical tool includes first and second jaws configured to clamp the tissue, each of the first and second jaws having at least one electrode thereon that is configured to apply the energy to the clamped tissue.

13. The surgical system of claim 8 , wherein the energy is radiofrequency energy.
