Description
Technical Field
The utility model belongs to the technical field of image positioner and specifically relates to a positioner is used in inspection of animal vertebra image is related to.
Background
Medical imaging is a technique and process for non-invasively acquiring internal tissue images of a human body for medical treatment or medical research, and is an inference algorithm of the inverse problem, i.e., the cause is derived by the reverse inference of the result. With the development of the subject of the experimental animal, the medical imaging technology is gradually applied to the aspects of establishing a disease model of the experimental animal, observing and evaluating the disease treatment effect, observing the drug metabolism and the like. The imaging technology can image the internal tissue structure and organs of an animal body, so as to know the image anatomical structure, physiological function condition and pathological change of the animal body, achieve the purposes of diagnosis, treatment and research, and the molecular imaging examination method can also evaluate the tissue cell metabolism, study the drug toxicology and drug metabolism dynamics, and generally carry out imaging examination by CT, MRI, PET-CT and the like. The spinal cord and other important nerves and blood vessels are in the spine of the animal, and pain, numbness, limb movement disorder, even paraplegia, stool and urine incontinence and life danger can be caused by small-volume pathological changes due to narrow space.
Therefore, the method helps to accurately position the displacement of the disease in the vertebral column, and creates the position and the size of the incision of the operation minimally invasive surgery, thereby creating conditions for minimally invasive resection of the disease in the vertebral canal. When the imaging examination is carried out on the experimental animal, the experimental animal is required to be fixed into a specific body position to obtain image information for examination due to the examination requirement, and in the animal imaging examination process, the body position fixation of the examination animal plays a vital role in an examination result.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a positioning device for animal vertebra image examination, which can fix animals and accurately position the specific position of the spine with problems, in order to overcome the defects of the prior art.
The purpose of the utility model can be realized through the following technical scheme:
the positioning device for animal vertebra image examination comprises a positioning plate for fixing an animal and a developing sheet capable of developing during image examination, wherein the developing sheet is clamped on the positioning plate, and the animal is fixed on the positioning plate.
Furthermore, a groove matched with the developing sheet is formed in the positioning plate, and the developing sheet is clamped and fixed with the groove. The height of the positioning plate and the developing sheet after the developing sheet is clamped is consistent, and the surface of the whole positioning device is approximately planar, so that the fixing of animals is facilitated.
Furthermore, the positioning plate is provided with a buckle for fixing animals. Since animals are difficult to keep calm while undergoing testing, much the same as humans, some snapping is required to secure the animal to the device, thereby keeping its spine nearly immobile.
Further, the number of the buckles is 2-6. If the animal is small, such as a gecko, only two animals can be used, and the animal can be fixed end to end, and if the animal is large, such as a mouse, four limbs of the animal are required to be fixed.
Furthermore, at least two through holes are formed in the developing sheet, and the through holes are filled with developing solution. These imaging solutions can be used to image the spine of an animal during imaging.
Further, the cross section of the through hole is triangular, rectangular or circular. And different patterns are used for convenient marking and recording.
Further, the spacing of each through hole is equal. The position of the vertebral column can be accurately positioned by the dichotomy after the positioning.
Furthermore, the number of the through holes is 2-20. If the animal is small, only a small number of through holes are needed to solve the positioning problem, and if the animal is large, the number of through holes needs to be increased, but if the number is increased too much, not only the improvement of the positioning accuracy is limited, but also the cost is excessively increased.
Further, the image examination includes an MRI scan.
Further, the animal includes a mouse, lizard or gecko.
Compared with the prior art, the utility model has the advantages of it is following:
(1) the positioning plate is provided with buckles for fixing animals, and the animals are difficult to keep calm when being detected, so that the animals can be fixed on the device by using the buckles, the spine of the animals keeps almost motionless state, anesthesia is avoided, the final observation conclusion is more accurate, the number of the buckles can be adjusted according to the size of the animals, and cost control is facilitated;
(2) the developing sheet is internally provided with through holes which are filled with developing solutions, the developing solutions can be developed together with the animal spines during image examination, the cross sections of the through holes are designed to be triangular, rectangular or circular according to design, when diseased animal spines are projected together with the cross sections of the developing solutions, marking and recording are facilitated, the intervals of the through holes are equal, and further accurate positioning of diseased positions is facilitated by a bisection method after positioning;
(3) the number of the through holes can be adjusted according to the size of the animal, and cost control is facilitated.
