This clinical trial is a prospective, multicentre, randomized, controlled study of high intensity focused ultrasound (HIFU) treatment of benign thyroid nodules. this study will include 240 patients with benign thyroid nodules that meet all ths the inclusion / exclusion criteria and will be randomly divided into two groups at 1: 1 ratio. Patients in the test group will be treated with high intensity focused ultrasound (HIFU), while patients in the control group will be actively observed and followed up by ultrasound examination. The primary objective of this clinical trial is to evaluate the efficacy of the test device in the treatment of benign thyroid nodules, and the secondary objective is to evaluate the safety of the test device in the treatment of benign thyroid nodules and the improvement of symptoms assessed by VAS score.
