초록 ▼

A method for coagulating tissue is disclosed. The method includes the steps of providing an electrosurgical apparatus including: an elongated flexible tube having a proximal end and a distal end and defining a longitudinal axis and at least one electrode mounted proximate to the tube for ionizing pressurized ionizable gas. The method also includes the steps of moving the distal end of the tube from a first position wherein the distal end is disposed in a generally parallel fashion relative to the tissue to a second position wherein the distal end directs pressurized ionizable gas flowing through the tube at an angle α with respect to the longitudinal axis and igniting the pressurized ionized gas through the at least one electrode.

1. A method for coagulating tissue, comprising the steps of: providing an electrosurgical apparatus including: an elongated flexible tube defining a longitudinal axis and having a proximal end and a distal end;a wire connected to the distal end of the tube, wherein the wire acts as a return electrode; andat least one electrode mounted proximate to the tube for ionizing pressurized ionizable gas;moving the wire from a first generally relaxed position wherein the tube is disposed in a generally parallel fashion relative to the tissue to a second retracted position wherein the distal end of the tube directs pressurized ionizable gas flowing through the tube at an angle with respect to the longitudinal axis; andigniting the pressurized ionizable gas through the at least one electrode. 2. A method according to claim 1, further comprising the step of regulating gas flow through the tube. 3. A method according to claim 1, wherein the pressurized ionizable gas is pressurized argon. 4. A method according to claim 1, wherein the angle relative to the longitudinal axis progressively changes proportionally to the amount of tension placed on the wire. 5. A method for coagulating tissue, comprising the steps of: providing an electrosurgical apparatus including: an elongated flexible tube having a proximal end and a distal end and defining a longitudinal axis, the tube including a sleeve being selectively extendable therethrough;a wire connected to the distal end of the tube, wherein the wire acts as a return electrode; andat least one electrode mounted proximate to the tube for ionizing pressurized ionizable gas;moving the sleeve from a first position wherein a distal end of the sleeve is disposed in a generally parallel fashion relative to the tissue to a second position wherein the distal end of the sleeve directs pressurized ionizable gas flowing through the sleeve at an angle α with respect to the longitudinal axis; andigniting the pressurized ionizable gas through the at least one electrode. 6. A method according to claim 5, further comprising the step of regulating gas flow through the tube. 7. A method according to claim 5, wherein the pressurized ionizable gas is pressurized argon. 8. A method according to claim 5, wherein the angle of the distal end of the sleeve relative to the longitudinal axis progressively changes proportionally to the distance the distal end of the sleeve extends from the tube.
