Abstract

A multi-functional element suitable for performing at least two surgical/therapeutic interventions, for example, the injection and cutting of tissue, with an anti-carbonization device to prevent the carbonization of tissue upon plasma coagulation by way of a suitable surgical instrument, where the surgical instrument has a feed line for an oxidizing agent, a feed line for a gas and an electrode for generating a plasma. A gas oxidizing agent mixture for producing a gas oxidizing agent plasma is provided by the anti-carbonization device.

First claim

The invention claimed is:

1. A surgical instrument suitable for performing at least two surgical/therapeutic interventions, said surgical instrument comprising:
a plasma coagulation device,
a fluid applicator for cutting and/or injecting tissue with fluid, and
an anti-carbonization device to prevent the carbonization of tissue upon plasma coagulation by the plasma coagulation device, the surgical instrument having a feed line for an oxidizing agent, a feed line for a gas and an electrode for generating a plasma,
wherein the anti-carbonization device provides a gas-oxidizing agent mixture for generating a gas-oxidizing agent plasma.

2. The surgical instrument of claim 1 , wherein the at least two surgical/therapeutic interventions comprise injection and cutting of tissue.

3. The surgical instrument of claim 1 , wherein the oxidizing agent is liquid.

4. The surgical instrument of claim 1 , wherein the oxidizing agent is gaseous.

5. The surgical instrument of claim 1 , wherein the oxidizing agent is an aerosol.

6. The surgical instrument of claim 5 , further comprising an evaporator for generating the aerosol.

7. The surgical instrument of claim 5 , further comprising an ultrasound generating device for generating the aerosol.

8. The surgical instrument of claim 5 , further comprising a baffle plate for generating the aerosol.

9. The surgical instrument of claim 1 , wherein the oxidizing agent is water.

10. The surgical instrument of claim 1 , wherein the gas is an inert gas.

11. The surgical instrument of claim 10 , wherein the inert gas is argon.

12. The surgical instrument of claim 1 , further comprising a two-substance atomization device.

13. The surgical instrument of claim 12 , wherein the two-substance atomization device is an internal-mixing device.

14. The surgical instrument of claim 12 wherein the two-substance atomization device is an external-mixing device.

15. The surgical instrument of claim 1 , further comprising a jacket, which in a region of the electrode has at least one opening to prevent a gas embolism.

16. The surgical instrument of claim 1 , further comprising a self-aspirating two-substance atomization device.
