Technical Field
The invention relates to the technical field of medical auxiliary appliances, in particular to a head fixing device for CT examination of a skull.
Background
CT examination of the cranium is a method of examining the cranium by CT. The skull CT is a novel examination method which is convenient, rapid, safe, painless and atraumatic to examine, and can clearly display the anatomical relationship of different cross sections of the skull and the specific brain tissue structure. Thereby greatly improving the detection rate of pathological changes and the accuracy of diagnosis. The skull CT examination has important significance for diagnosing most diseases of the cranium, the skull and the scalp.
The application of CT artery blood vessel imaging is more and more, and the application value in cerebrovascular aneurysm diseases is more and more. In cerebrovascular CT, if good imaging is to be obtained, the patient is required to remain still during the scan, which is often difficult for the patient, and a head fixation device is required. However, when the current patient carries out the CT examination, the existing head fixation is based on an examination bed head support, the middle part of a linear binding band is arranged at the forehead position, the two ends of the binding band are tightened, and the vacant part of the head support is filled with foam, so that the head of the patient is fixed. However, the binding of the binding band to the head cannot play a good fixing role, only the up-down direction can be limited, and the foam cannot be filled in each gap, so that once the head of a patient shakes, a doctor can only reluctantly complete the examination by repeatedly scanning for many times, and the image quality is not influenced.

The working principle of the invention is as follows: in use, the holding frame 10 is firstly held on the bed head, the occluding component 32 is suspended above the mouth of a patient by rotating the cross bar 22, and the bottom end of the occluding component 32 is moved to the mouth of the patient by extending the length of the connecting rod 40; then, the first occlusion disc 322 is rotated to enable one occlusion rod 325 to rotate to the oral position of the patient, so that the patient bites the occlusion rod 325 by using teeth; then, the two holding plates 331 are moved to make the opposite sides of the two holding plates 331 stick to the faces of the two sides of the mouth of the patient, and the holding plates 331 are pushed to stick to the face of the patient by the restoring elastic force of the holding springs 332, so that the head of the patient is fixed.
After the CT detection of the patient is completed, the teeth of the patient are enabled to loosen the occlusion rod 325, the two clamping plates 331 are separated in the opposite direction, and the length of the connecting rod 40 is shortened; thereafter pulling the clench piece 50 outwardly to disengage the clench block 51 from the first and second bite disks 322, 323; the end of the bite bar 325 is removed from the bite block.
The invention has the beneficial effects that: the head fixing device for the CT examination skull is clamped on a bed head through a clamping frame 10, so that the whole device is fixed on the bed head; the bottom end of the occluding component 32 is moved to the position of the mouth of the patient through the adjustment of the lengths of the support frame 20 and the connecting rod 40; by rotating the first occlusion disc 322, one occlusion rod 325 is rotated to the mouth, so that the patient bites the occlusion rod 325 by using teeth, and simultaneously the bottom ends of the two clamping plates 331 are clamped on the faces at the two sides of the mouth, thereby mutually matching and fixing the head of the patient together, and avoiding the influence on the detection result caused by the shaking of the head in the CT detection process; further, the provision of the bite piece 50 facilitates the installation and removal of the bite bar 325 while avoiding cross-contamination.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
