Description
Technical field
The present invention relates to a kind of auxiliary medical apparatus, particularly relate to a kind of multi-angle CT imager for jawbone, tooth and cervical region.
Background technology
In dental treatment, generally all can carry out CT imaging to some particular location of jawbone or tooth, doctor judges pathological changes according to imaging or takes effective therapeutic scheme targetedly, taper CT imager has the distinctive advantage of fan-shaped CT imager, existing CT imager often needs patient ceaselessly to alter one's posture because of the problem of angle when taking human body jawbone or tooth, cumbersome, patient keeps some posture to be difficult to keep static, unfavorable for imaging effect like this.
Summary of the invention
The invention solves an above-mentioned difficult problem, adopt a kind of level angle 360 °, the multi-angle cone-beam CT imaging instrument of vertical angle 90 °.
Technical scheme of the present invention is a kind of multi-angle cone-beam CT imaging instrument, comprise: the bracing frame be provided with successively from top to bottom, the retainer that x-ray discharger and the x-ray receiving device be oppositely arranged is housed and position adjust chair, it is characterized in that, also be provided with guide rail, described guide rail is fixedly suspended on bracing frame, described guide rail is arc, and described retainer slippage angle on guide rail is not less than 90 °.
Preferably, described guide rail comprises horizontal component, 90 ° of circular arc shaped portion and vertical portion, the plane of above-mentioned three part compositions and horizontal plane.
Preferably, described retainer is reverse U shape, and its two ends are respectively provided with described x-ray discharger and described x-ray receiving device, and described retainer top is provided with two guide wheels, and described guide wheel is locked in described guide rail.
Preferably, be provided with lowering or hoisting gear, and can rotate freely in horizontal plane below described position adjustment chair, be provided with headrest above described position adjustment chair, the position of described headrest can be adjusted between described x-ray discharger and described x-ray receiving device all the time.
Preferably, described guide wheel is controlled by the first driving device, and described lowering or hoisting gear is controlled by driving device.
Preferably, described 90 ° of circular arc shaped portion centers of circle are all the time between described x-ray discharger and described x-ray receiving device.
Beneficial effect of the present invention is: retainer can slide on arc-shaped rail, shooting angle can be changed at vertical direction, position adjustment chair can rotate freely in horizontal plane, and can adjust upper-lower position, and two kinds of angle adjustment also use all angles that can meet doctor's shooting.
Accompanying drawing explanation
Fig. 1 is preferred embodiment structural representation;
In figure: 1. bracing frame, 2. retainer, 3. position adjustment chair, 4. x-ray discharger, 5.X line receiving device, 6. guide rail, 7. guide wheel, 8. the first driving device, 9. the second driving device, 10. lowering or hoisting gear, 11. headrests, 12. horizontal components, 13.90 ° of circular arc shaped portion, 14. vertical portions.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
As shown in Figure 1, the multi-angle cone-beam CT imaging instrument of an embodiment of the present invention, comprising: be provided with bracing frame (1) from top to bottom successively, the guide rail (6) be fixed on bracing frame, the retainer (2) be fixed on guide rail, position adjustment chair (3).
Guide rail (6) comprising: horizontal component (12), 90 ° of circular arc shaped portion (13) and vertical portion (14), two guide wheels (7) that retainer (2) is provided with can be controlled mobile or static on guide rail by the first driving device (8), retainer (2) two ends are oppositely arranged x-ray discharger (4) and x-ray receiving device (5), and the center of circle of 90 ° of circular arc shaped portion (13) is positioned between x-ray discharger (4) and x-ray receiving device (5) all the time.
Adjustment chair (3) bottom, position is provided with the lowering or hoisting gear (10) driven by the second driving device (9), position adjustment chair (3) freely can be rotated in horizontal plane, adjustment chair (3) top, position is provided with headrest (11), and the position of headrest (11) can adjust to the position between x-ray discharger (4) and x-ray receiving device (5) all the time under the first driving device (8) and the second driving device (9) coordinate simultaneously.
When the present invention works, patient is sitting on position adjustment chair (3), head is close to headrest (11), now retainer (2) is positioned at guide rail (7) horizontal component, the line of x-ray discharger (4) and x-ray receiving device (5) and plane-parallel, start the second driving device (9) and drive lowering or hoisting gear (10) adjustment position adjustment chair (3) highly, the jawbone of patient is made to be positioned between x-ray discharger (4) and x-ray receiving device (5), now can adjust chair (3) angle in horizontal plane by position of rotation, doctor can take the imaging of different perpendicular.
Holding position adjustment chair (3) is highly constant or finely tune its height, starting the first driving device (8) drives retainer upper mobile at guide rail (7), retainer (2) can produce at horizontal component (12) and move left and right, produce in vertical portion (14) and move up and down, move at 90 ° of circular arc shaped portion (13) multi-angle rotaries, whole all-moving surface is perpendicular to horizontal plane, such doctor can take the imaging of patient's jawbone above-below direction or incline direction plane, now adjust chair (3) by position of rotation and just in horizontal plane, multi-angle can coordinate its shooting imaging.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
