Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary devices, in particular to a patient head supporting device for thyroid surgery. Background Art

[0002] Thyroid surgery usually involves cutting 2-8cm of skin below the neck, removing all or part of the thyroid gland. The incision is usually made in the fold of the skin on the neck to make it less obvious.

[0003] During surgery, the patient's head usually needs to be fixed, supported and lifted up. When the head is fixed directly, the chin is pressed down, causing the neck to contract during surgery, which obstructs the surgical field of view. Medical staff need to spend more time moving the patient's head to adjust the fixation, which is extremely inconvenient and takes too long to prepare for surgery.

[0004] Therefore, it is necessary to design a patient head support device for thyroid surgery with a stretching function. Utility Model Content
