[0002] Interventional surgery is an emerging minimally invasive treatment technique. Without exposing the lesion through surgery, it uses advanced imaging equipment (such as DSA, ultrasound, and CT) to diagnose and treat diseases by inserting tiny instruments such as needles and catheters into the body. Postoperatively, patients are required to lie flat for at least six hours, and sometimes even 24 hours. During this time, they must lie flat to eat, and the operated limb cannot be bent. Currently, patients may eat by tilting their head, which is very inconvenient and uncomfortable.

[0003] Patent application number 202323060344.5 discloses a patient fixation frame head lifting device, including: a support mechanism, the upper end of the support mechanism is slidably connected to a placement mechanism, the side end of the support mechanism is threadedly mounted with two fixing bolts, and one end of the fixing bolt passes through the support mechanism and the placement mechanism in sequence.

[0004] The above technical solution uses an adjustable placement board to support the neck, thereby raising the head. However, since the height of the placement board is difficult to adjust during use, and the patient needs to get up before leaning on the top of the placement board, the operated limb will be affected during the process of getting up. Therefore, the present application provides a patient fixation frame head lifting device to meet the needs. Utility Model Content
