Description

A CT scanning head fixator

Technical Field

The utility model relates to the technical field of fixators, in particular to a CT scanning head fixator.

Background Art

CT is computer tomography, which uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with highly sensitive detectors to scan sections of a certain part of the human body one by one. It has the characteristics of fast scanning time and clear images, and can be used to examine a variety of diseases. At present, during CT scanning, in order to prevent the patient from moving around, a head fixator is needed to fix the patient's head during scanning;

For example, the invention patent with Chinese patent publication number CN107951502B discloses a head fixing device for radiology, including a base plate, a lifting mechanism, a fixed shaft, a pressing mechanism, a clamping mechanism, a winding bin, a winding mechanism, a first pull rope and a second pull rope, the lifting mechanism includes a piston column and a sleeve that fit together, the clamping mechanism includes a clamping plate and an ear plate, and the winding mechanism includes a first wire wheel and a second wire wheel;

It was found during use of the above-mentioned prior art that the device achieves the height change of the lifting mechanism by setting an air pump to inflate and discharge air, so that the clamping mechanism contacts the patient's forehead, and by turning the crank, the winding mechanism brings the two ear plates closer together through the first pull rope and the second pull rope, and the splint clamps the patient's head to achieve a fixing effect. However, after the device fixes the patient's head, the clamping mechanism and other components located above the head are likely to block the area to be scanned on the patient's head, thereby affecting the contrast effect and reducing work efficiency, resulting in poor practicality.
