Abstract
The invention provides an MRI (magnetic resonance imaging) dynamic cervical vertebra scanning bracket, which is characterized by comprising a horizontally fixed bottom plate, a curved plate, a moving block, a vertical plate and an adjusting rod, wherein the curved plate is connected with the bottom plate through a rotating shaft; a coil groove is formed in a part, near the rotating shaft, on the curved plate; the moving block is a triangular block, and is arranged between the outer arc of the curved plate and the bottom plate; the moving block moves inwards, and thus, the curved plate can be pushed to rotate around the bottom plate; the vertical plate is arranged at the outer end of the bottom plate; the adjusting rod is a threaded rod; the adjusting rod passes through the vertical plate so as to be in contact with the moving block; the adjusting rod rotates relative to the vertical plate, and thus, the moving block can be pushed to move; scale marks are arranged in the length direction of the adjusting rod. The MRI dynamic cervical vertebra scanning bracket provided by the invention has the advantages that the adaptability is good, and the cervical vertebra scanning radian can be flexibly and accurately adjusted.
Description
Technical field
The present invention relates to a kind of MRI scanning assistive device, particularly a kind of MRI dynamic cervical vertebra scanning bracket.
Background technology
Routine MRI inspection have multi-faceted, soft tissue resolution is high, without features such as ionizing radiation, obviously be better than x-ray plain film and CT examination, it is the topmost Image Examination of current cervical spondylosis, but routine MRI neutral position checks, cervical spondylosis situation can not be reflected comprehensively, therefore, many positions MRI checks, for realizing more accurately, comprehensive cervical vertebra inspection provides one may.At present, checking for realizing cervical vertebra many positions MRI, to adopt in patient's occipital bone or neck shoulder junction pad cotton pad method more, but this method Shortcomings: adaptability is bad, cervical vertebra scanning radian can not flexible, and it is nonstandard that cervical vertebra scans curvature.
Summary of the invention
Object of the present invention will provide a kind of exactly and adapt to, and cervical vertebra can be regulated flexibly and accurately to scan the MRI dynamic cervical vertebra scanning bracket of radian.
For achieving the above object, the present invention by the following technical solutions:
A kind of MRI dynamic cervical vertebra scanning bracket, comprise horizontal fixed base plate, arc, movable block, riser and adjusting rod, described arc is connected with base plate by turning cylinder, arc arranges coil recess in the part near turning cylinder, described movable block is corner block, be placed between the outer arc of arc and base plate, movable block moves inward and can promote arc and rotate around base plate, described riser is placed in the outer end of base plate, described adjusting rod is threaded rod, contact with movable block through riser, adjusting rod can promote movable block relative to riser rotation and move, its length direction arranges scale marker.
Described adjusting rod arranges longitudinal section, and scale marker is on longitudinal section, and the inclined-plane of described movable block is outwardly cambered surface, and bottom surface arranges draw runner, described base plate is arranged the chute matched with draw runner.
Described movable block arranges counterbore, and the outer end of described adjusting rod is placed in counterbore.
Operation principle of the present invention is: promote movable block by threaded rod and move, and then promotion arc rotates around base plate, realizes the patients head be placed on arc and moves, thus regulate cervical vertebra scanning angle.
The invention has the beneficial effects as follows: 1, rotated by threaded rod, can flexibly and continuous print regulate arc relative to the angle of base plate, do not need patient motion can regulate scanning angle continuously flexibly, the artificial mode in patient's cervical region underlay cotton pad is many easily compared to existing technology, and adaptability is good many.2, threaded rod identifies scale, each scale corresponds to the angle of rotation, more quantitatively can hold the angle of cervical vertebra scanning accurately.

In figure: 1, base plate, 2, arc, 3, movable block, 4, riser, 5, adjusting rod, 6, turning cylinder, 7, groove, 8, longitudinal section, 9, draw runner, 10, chute.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.As shown in the figure, the present invention includes horizontal fixed base plate 1, arc 2, movable block 3, riser 4 and adjusting rod 5, arc 2 is connected with the middle part of base plate 1 by turning cylinder 6, can rotate relative to base plate 1.The arc of arc 2 in indent, the size of radian is with suitable people's headrest for design principle, and arc 2 arranges the groove 7 for placing scanning coil in the part near turning cylinder 6.Movable block 3 is corner block, be placed between the outer arc of arc 2 and base plate 1, the inclined-plane of movable block 3 is outwardly cambered surface, globoidal structure is compared ramp structure and is more conducive to reducing frictional resistance when contacting with arc 2, and it is design principle that radian and the shape of cambered surface are beneficial to the frictional resistance reduced when contacting with arc 2.Riser 4 is placed in the outer end of base plate 1, can be fixedly connected with base plate 1, also can be made as integrative-structure with base plate 1.Adjusting rod 5 is threaded rod, processing longitudinal section, both sides 8 on the length direction of adjusting rod 5, longitudinal section 8 identifies scale, because the relative distance of stretch out and draw back of riser 4 of adjusting rod 5 and the rotational angle of arc 2 exist relation one to one, on longitudinal section 8, directly can identify the numerical value of rotational angle.
Move on base plate 1 for ease of movable block 3, bottom surface arranges draw runner 9 to movable block 3, base plate 1 arranges the chute 10 corresponding with draw runner 9, so can reduce the resistance to sliding of movable block 3, coordinating also by draw runner 9 and chute 10, ensure the reliable and stable of movable block 3 motion track, the situation of offset direction can not occur.As a same reason, for ease of adjusting rod 5 and movable block 3 contact stabilization, movable block 3 arranges counterbore, and the outer end of adjusting rod 5 is placed in counterbore.
Occupation mode of the present invention is: this device base plate 1 is fixed on scanning bed on, patient takes on back and lies on base plate 1, head pillow is on arc 2, cervical region is in groove 7 position, scanning coil is placed in groove 7, operate machines and patient's cervical region scanned, in scanning process, inwardly stretched out by the relative riser 4 of rotary regulating lever 5, promote movable block 3 to move, promote arc 2 and rotate around base plate 1, thus change cervical vertebra scanning angle, can accurate assurance scanning angle by observing scale numerical value on adjusting rod 5, can be positioned at accurately and need scanning angle; When needing arc 2 to fall after rise, relative riser 4 outwards exits adjusting rod 5, loses the thrust support of adjusting rod 5, and under arc 2 and patients head's action of gravity, movable block 3 can be outwards mobile, and arc 2 falls after rise.
Application the present invention, can carry out the inspection of many positions easily to Patients with Cervical Spondylopathy, check result more comprehensively, more accurate, be particularly conducive to the diagnosis of early diagnosis to Patients with Cervical Spondylopathy and the complicated state of an illness.The present invention can be used alone, and also can be made as one with scanning bed, daily do not do cervical vertebra check time, regulate arc 2 to being applicable to angle, this device can be used as patient and rest the head on use.
The present invention can adopt the good PVC material of strength ratio to make, and to reduce product cost, is beneficial to and applies.
The present invention is not limited to illustrated embodiment, and based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
