[0002] The thyroid gland is a very important gland in vertebrates and is an endocrine organ. In mammals, it is located below the thyroid cartilage in the neck and on both sides of the trachea. The human thyroid gland is shaped like a butterfly, like a shield, hence the name. When the thyroid gland becomes diseased, it needs to be partially removed. During thyroidectomy, the thyroid gland must first be separated from the tissue and the diseased part must be pulled up before surgical removal can be performed.

[0003] The incision for thyroid surgery is usually made in the neck. The doctor will decide the location and size of the incision based on the needs of the operation and the specific situation of the patient. Generally speaking, the surgical incision will be as small as possible to reduce postoperative scarring and pain. During the operation, the doctor will use a scalpel or other instruments to cut the incision layer by layer to expose the thyroid tissue. Then the doctor will usually use special instruments to expand the incision to better expose the surgical area. These instruments include retractors or hooks, which can expand the tissues on both sides of the incision to increase the surgical field of view and facilitate the doctor's operation.

[0004] However, the existing retractors for thyroid surgery require the cooperation of multiple medical staff to hold them and separate the incisions, which results in high labor intensity for the surgery and serious waste of medical resources. At the same time, too many medical staff lead to a smaller effective space, which is not conducive to doctors performing the surgery and increases the difficulty of the surgery.
