Argon coagulation uses the phenomenon of good conduction of high frequency current by ionized argon. Argon is a chemically inert gas, devoid of physiological effects and non combustible. Under the effect of current, it becomes ionized and forms a plasma cloud in which electric arcs are formed.
In argon coagulation, there is no contact of the active electrode with the tissue, and the distance between the surgical instrument and the tissue in open surgery is up to about 5 mm, and in endoscopic surgery up to about 3 mm.
The thermal effect occurs at the time when a spark jumps from the active electrode tip to the tissue. The length of the plasma arc between the probe tip and the tissue depends on the selected power, resistance of the target tissue and argon flow rate. Usually the distance between the active electrode and the tissue is 3 to 5 mm, depending on the selected coagulation parameters.
When using argon coagulation, observe all precautions for standard monopolar coagulation. Read the instructions for using argon components. Class 4.8 (99.998%) or 5.0 (99.999%) argon is used for argon coagulation.
Under the influence of high temperature and mechanical pressure, collagen tissue is shrinking and becomes a very durable sealer. Vessels closed with the use of the ThermoStapler® system are capable of withholding significant blood pressure.
The vessel can easily be cut with the use of surgical scissors. There is no risk of bleeding.
The parameters of the tissue during the process of sealing are monitored at all times. The system uses a sound message to inform about achieving the optimal level of sealing and stops the current flow automatically. It is recommended to keep the instrument's tips cool and moist.
The sealing area is flexible. The vessel can easily be cut with the use of surgical scissors. There is no risk of bleeding. The ThermoStapler® system enables closing vessels with a diameter of up 7 millimetres and larger, however each time it is necessary to assess the quality of the closure by the operator.
While the ThermoStapler® system is being used, the area of heated tissue is more limited than with the use of standard bipolar coagulation. The risk of damaging adjacent tissues is minimal. The safety of the closure with the use of the ThermoStapler® system is comparable to the use of other mechanical methods.
