Abstract
A plasma probe (10) comprises a fluid line (14) that is preferably configured as a hose and an electrode (17) arranged therein, the tip (20) of which is located in the proximity of the outlet opening (16). The electrode (17) comprises a hydrophobically configured surface section (21). As an option, additional elements of the plasma probe (10), particularly in the proximity of the outlet opening (16), can be provided with hydrophobic surfaces. Such a probe comprises a remarkably improved ignition readiness and an improved steadiness due to the permanence of the obtained discharge base point.
Claims11
A plasma probe (10) for plasma coagulation of biological tissue, comprising:
- a fluid line (14) having at least one channel (14a) configured to be connected to a gas source (13), wherein the at least one channel (14a) leads to a distal end (15) of the fluid line (14) and terminates at an outlet opening (16) at the distal end;
- and
- an electrode (17) in or proximate to the outlet opening (16) configured to be connected to an electrical source (12) via a line (18);
- wherein the electrode (17) includes a hydrophobic surface section (21).
