Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a head fixing device suitable for patients undergoing oral flap surgery. Background Art

[0002] At present, common head fixation devices on the market usually use traditional straps, support frames and other structures to limit the movement of the patient's head to assist in postoperative recovery. Although these devices can provide fixation to a certain extent, there are many shortcomings in actual application. First of all, the adjustment mechanism of many existing devices is relatively simple, and it is impossible to accurately adjust the angle or position according to the specific needs of different patients, which limits their scope of application. For patients with different body shapes or postoperative recovery status, existing technologies are often unable to provide personalized support, resulting in unsatisfactory fixation effects and poor comfort.

[0003] Secondly, existing devices generally offer simple neck support designs, often relying solely on a simple support pad or rigid frame to maintain the neck's position. While these designs provide some support, they fail to account for the changing angles of the neck and the discomfort that can result from prolonged wear. This can lead to patients experiencing pressure, neck muscle fatigue, and even poor blood circulation, exacerbating discomfort during recovery.

[0004] Furthermore, existing technologies often have complex adjustment features and inconvenient operation. Many fixation devices have overly cumbersome adjustment mechanisms, making them prone to errors by patients or caregivers. This increases the difficulty of use for patients, especially during the postoperative recovery period, when patients often have poor coordination and frequent adjustments can lead to delays and inconvenience in recovery.

[0005] Furthermore, existing devices often lack the comfort needed for extended wear. Many immobilization devices are designed without adequate consideration for prolonged skin contact, which can easily cause pressure, skin damage, or discomfort. This is particularly true of the head and neck, where the device comes into contact with the patient. Prolonged immobilization can easily lead to skin redness, swelling, damage, and even pressure sores, compromising postoperative recovery. Summary of the Invention
