Abstract
The utility model provides a magnetic resonance skull surface locator which is characterized by having a gridding structure formed by cross-linking a plurality of horizontal pipes and upright pipes. Two ends of the horizontal pipes and the upright pipes are closed. Water is filled in the horizontal pipes and the upright pipes. When using, the locator is pasted at a skull surface corresponding to the encephalic pathology so as to perform magnetic resonance check and locate, thus designing an operative incision. The magnetic resonance skull surface locator has simple and convenient use and obvious locating effect, can obviously promote the accuracy rate of locating before the operation of small space-occupying lesion in the skull, and can precisely perform MRI location on a top space-occupying focus. The magnetic resonance skull surface locator has the advantages of conveniently taken materials, easy manufacture, simple operation, no wound and worthiness of clinical application and dissemination. The accurate location of the skull surface can furthest decrease the injure degree of the operation and decrease the postoperative complications.
Description
Technical field
This utility model relates to a kind of medical assistive device, particularly a kind of magnetic resonance cranium table localizer.
Background technology
Nuclear magnetic resonance (MRI) has been the leap again since CT comes out in the iconography field.Atomic nucleus is made up of proton and neutron, and proton and neutron all have the feature of spin, can cancel each other when their quantity is even number, can produce nuclear spin when being odd number, produces the magnetic resonance phenomenon.MRI makes according to this phenomenon.
In the prior art; neurosurgeon is when carrying out the art prelocalization; often only rule of thumb; contrast CT and MRI sheet roughly mark the position of intracranial mass lesion on the head surface; cause location of operation and incision design inaccurate through regular meeting like this; particularly the less pathological changes in brain deep has increased a lot of difficulties to operation, even produces serious consequence.Brain stereotactic technology and neural airmanship to the intracranial lesion accurate positioning, but still can't be promoted the use of at basic hospital at present, and it is a kind of both accurately convenient therefore to need in a hurry to seek, economical and practical again location equipment.
The patent No. is that 200620004319.2 Chinese patent application discloses a kind of " paliform seal wire cranium table localizer ".This localizer is used for locating use into the intracranial small lesion on the CT machine, is to be attached to the roughly relative cranium table view field of intracranial lesion with highdensity label, carries out CT scan then.Intracranial lesion and the cranium list notation thing relation shown according to CT are gone into the direct very exactly telltale mark of cranium point of puncture on cranium gauge outfit skin with cranium table projected position or the best of intracranial lesion.The defective of this localizer mainly contains: (1) can only be used in the CT examination location, and can not be used in the nuclear magnetic resonance check location; (2) CT location grid can not be used too greatly or at all at the location time error that carries out the occupy-place of calvarium portion; (3) there is the pseudo-shadow of bone in CT; (4) there is x-ray radiation in CT examination; (5) get involved radiography with the conduit inconvenience of drawing materials.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of simple and reasonable, accurate positioning magnetic resonance cranium table localizer easily is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.This utility model is a kind of magnetic resonance cranium table localizer, is characterized in, interconnection becomes fenestral fabric with vertical tube by some transverse tubes for it, and transverse tube and vertical tube closed at both ends are equipped with water in transverse tube and the vertical tube.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described magnetic resonance cranium table localizer is characterized in, square crossing connects between described transverse tube and the vertical tube.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described magnetic resonance cranium table localizer is characterized in that the distance between 2 adjacent transverse tubes is 1.5cm, and the distance between 2 adjacent vertical tubes is 1.5cm.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described magnetic resonance cranium table localizer is characterized in that described transverse tube and vertical tube respectively are the 6-8 root, and length is 8-11cm.
The material of this utility model magnetic resonance cranium table localizer can adopt the transfusion leather strap about diameter 0.35cm to make, and has been full of water inside.In magnetic resonance examination, the relaxation time of water is the longest, and therefore, hydrous matter presents shadow on T1 weighting picture, and presents highlighted shadow on T2 weighting picture.When this utility model uses, it is attached to the relative cranium table view field surface of focus, and makes a pipe and median line or OM line overlap, carry out MRI and scan.Can clearly show that in the cranium table position one arranges the anchor point of highlighted shadow mutually at T2, the patient of top occupy-place can make the circle, front and back according to sagittal plain according to crown circle, the left and right sides that makes occupy-place; The patient of temples occupy-place can make the bound of occupy-place according to crown position, boundary before and after making according to unenhanced position, thereby with the cranium table projected position of intracranial lesion very accurately directly telltale mark on cranium gauge outfit skin.Thereby design best operative incision, allow patient obtain best treatment.
Compared with prior art, this utility model is easy to use, and locating effect is remarkable, can significantly improve the accuracy rate that intracranial reduced dimension sexually transmitted disease (STD) becomes the art prelocalization; It can point-devicely carry out MRI for the focus of top occupy-place and locate; This utility model is drawn materials conveniently, easy to manufacture, simple to operate, noinvasive, is worth clinical application.And the degree of injury that the accurate location of cranium table can alleviate operation has to greatest extent reduced the generation of post-operative complication.
