In general, the treatment for the lesion with the diameter of 1.0-1.5cm can be completed by one needle1cm tip, but it is required for multiple needles treatment for the lesion with the diameter of2cm, in order to achieve the goal of completely inactivation of tumor cells.

 

Watts-controlling mode:

The setting time is 5 minutes. 

Unipolar needle (19G, non-retractable, operating length: 1cm); setting power: 7-10watts, operating until the generator stopped automatically.

Unipolar needle (19G, non-retractable, operating length: 0.5cm); setting power: 5-7watts, operate until the generator stopped automatically.

Monopole needle (19G, operating length: 1cm); setting power: 3-5watts, operating until the generator stopped automatically.

Principle of power selection

1.use high power and short time ablation for benign tumor.

2.Use low power and longer time ablation for malignant tumors.

Operating note: rotate the electrode needle when the temperature reaches to 100, so as to prevent adhesion.

 

Temperature-controlled mode:

The setting temperature is 99, and the setting time is 10 minutes.

Monopoleneedle (19G, non-retractable, operating length: 1cm); setting power: 20-25watts, make the corresponding adjustment according to the circumstance of temperature rise.

Monopole needle (19G, non-retractable, operating length: 0.5cm); setting power: 15-20watts, make the corresponding adjustment according to the circumstance of temperature rise.

Bipolar needle (19G, operating length: 1cm); setting power: 7-15watts, make the corresponding adjustment according to the circumstance of temperature rise.

Operating note

1. Monitor the circumstance of the gas enhancement of the thyroid tumor by B ultrasonic, and move the electrode needle according to the circumstance of the gas enhancement during the operation.

2.Rotate the electrode needle when the temperature reaches to 100℃, so as to prevent adhesion.
