In recent years, with the increasing detection rate of thyroid nodules, there are more and more treatment options for thyroid nodules. One of the most representative treatment options is the ablation of thyroid nodules. The basic principle of this treatment is to use a low-temperature sterile needle inserted into the patient’s thyroid nodules to activate a temperature of about 70 degrees Celsius to heat the thyroid nodules, during which the microwave effect is fully utilized to deprive the patient’s nodules of blood supply, thereby reducing the size of the nodules and even eliminating them completely. In clinical practice, it is widely used for some benign thyroid nodules.
