Thyroid nodule ablation surgery is a minimally invasive procedure for the treatment of thyroid nodules. Specific steps are as follows: 1, the patient takes the lying position after general anesthesia, the surgical area is routinely disinfected with sterile towels. 2, the ablation needle is connected to the device instrument under the guidance of color ultrasound, the tip of the ablation needle is slowly inserted into the thyroid gland nodule. 3, turn on the ablation device, the setting of 15W lasts for 3-5 minutes, and the color ultrasound can be observed under the thyroid nodule is completely carbonized, that is to say, the elimination of the nodule, and then you need to remove the ablation needle to avoid irreversible damage to the parathyroid gland and the laryngeal nerves caused by the continuous high temperature. At this time, the ablation needle needs to be removed to avoid irreversible damage to the parathyroid glands and the recurrent laryngeal nerve caused by the continuous high temperature.
