Argon coagulation uses ionized argon gas to conduct high-frequency current. Argon is a chemically inert, non-combustible gas without physiological effects. When subjected to current, it becomes ionized and forms a plasma cloud in which electric arcs are formed. The thermal effect occurs when a spark jumps from the active electrode tip to the tissue. There is no contact between the active electrode and the tissue. The distance between the surgical instrument and the tissue is about 5 mm in open surgery and up to 3 mm in endoscopic surgery. The length of the plasma arc depends on the selected power, tissue resistance, and argon flow rate. Typically, the distance between the active electrode and the tissue is 3 to 5 mm.
- Immediate hemostasis helps efficiently coagulate large areas of bleeding surfaces.
- Limited penetration depth of approximately 3 mm minimizes the risk of perforation.
- Minimal tissue carbonization compared to standard electrocoagulation.
- No tissue vaporization, which minimizes the risk of perforation.
- No contact between the applicator and tissue means no tissue adhesion.
- Less surgical smoke, providing good visibility of the operating area.
- Reduced smoke eliminates unpleasant odors.
- Precise application of thermal energy reduces procedure time.
- Constant, minimum depth of thermal effect.
- During the coagulation of soft tissues, argon plasma minimizes the risk of carbonization, and as a result of this, procedures are safe and controlled.
- The method can be safely used in thin-walled organs due to the limited depth of tissue damage.
- The desired effect is obtained with significantly less power compared to standard high voltage coagulation, reducing the amount of heat delivered to the patient’s tissues.
- Efficient coagulation of large bleeding areas due to immediate hemostasis.
- Minimized risk of perforation due to limited penetration depth and no tissue vaporization.
- Reduced tissue damage due to minimal tissue carbonization compared to standard electrocoagulation.
- Improved surgical visibility due to less smoke.
- Reduced unpleasant odors due to reduced smoke.
- Faster procedures due to precise thermal energy application.
- Enhanced safety due to minimal thermal effect depth and lower power usage.
- Safe for thin walled organs due to limited tissue damage.
1. Argon gas is delivered through an electrode.
2. High-frequency current is applied to the argon gas, causing it to ionize and form a plasma.
3. The plasma arc is directed towards the tissue from a distance of 3-5 mm.
4. Thermal energy is delivered to the tissue, causing coagulation.
5. The distance is maintained without contact between the electrode and tissue.
The source does not specify a session duration, but it does mention that precise application of thermal energy results in reducing procedure time.
