A device for immobilizing the patient's head during cervical spine surgery

Abstract

The invention discloses a patient's head fixation device in cervical spine surgery, which includes a head support pad installed on the head of the operating bed, the outer end of the head support pad is fixedly connected to a head fixation structure through a connecting plate; The fixed structure of the upper part is composed of a plurality of crossed arc cross arms and a supporting slide rail. The ends of two adjacent cross arc cross arms are rotatably connected by the first connecting ring, and the middle part is rotatably connected by the second connecting ring. ; The arc-shaped cross arm is installed on the support slide rail, and the outer side of the support slide rail is equipped with a drive structure that drives multiple arc-shaped cross arms to extend or contract; Any one of the first connecting rings is installed with a clamping structure, and the hemostatic cotton is clamped between the multiple clamping structures. This application aims at the situation that the patient needs to lie prone on the operating bed during the operation of the cervical spine, and fixes the patient's head through a ring-shaped multi-directional fixing structure.

Description

technical field [0001] The invention relates to the technical field of cervical spine surgery operation equipment, in particular to a patient head fixing device in cervical spine surgery operations. Background technique [0002] With the change of lifestyle, the number of people who have been bowing their heads for a long time and working at desks has increased. In recent years, the prevalence of cervical spondylosis has been increasing, and the age of onset has a younger trend. [0003] In the treatment of cervical spondylosis, the early conservative treatment can use X-ray or CT-guided interventional sealing, radio frequency, ozone and other technologies to perform local intervention on the location of nerve root compression to relieve nerve root edema and inflammation, thereby reducing nerve root compression. At the same time, it has the function of accurately diagnosing the responsible segment of the disease in patients with cervical spondylosis. In the later cervical e...

Problems solved by technology

In the later stage of cervical spine endoscopic surgery, the cooperation of the patient under local anesthesia is also required. All of the above operations have high requirements on the patient's compliance and physical strength, especially when the puncture is performed through the lateral and anterior lateral approaches. The puncture needle is close to the vertebral artery and spinal cord, and the operation risk is high
