Abstract
The present invention relates to a multifunctional panoramic camera for the tomography of an oral cavity curved surface. The existing irradiation cameras in hospitals are used as radiation sources so that a patient sitting on a chair seat of the camera can randomly make triaxial continuous conversion, and a film loaded in a cassette can be driven to synchronously rotate. The tomography images of complete teeth can be formed on a piece of film through a single exposure; moreover, the images of positions, such as a maxillary bone, a mandibular bone, a temporo-mandibular joint, a maxillary sinus, a nasal cavity, etc. can be simultaneously displayed.
Description
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of oral cavity curved surface panorama layer radiography frame.
As everyone knows, because the human body dental arch has certain radian, therefore, with can not the break forth photo of denture of plane body layer Photographic technique.Understand the general picture of denture, just must be on the ordinary x-ray photography device carrying out 14 film making with intraoral method could solve.This not only increases patient's misery, and patient and cameraman also will accept heavy dose of X ray.The oral cavity curved surface tomograph mostly is external production at present, because of its complex structure, function singleness, costs an arm and a leg, and is difficult to wide popularization and application, has only utmost point individual hospitals to have at present, and the patient of basic unit does this and checks difficulty.
The object of the present invention is to provide a kind of oral cavity curved surface panorama layer radiography frame, this photography support cooperates with existing each hospital's X-ray machine, make it single exposure and the tomography imaging of denture can be impinged upon on the film, and positions such as upper jaw bone, mandibular bone, temporomandibular joint, maxillary sinus, nasal cavity can be shown simultaneously.
The object of the present invention is achieved like this, that is: this oral cavity curved surface panorama layer radiography frame, comprise X-ray machine, its main composition is a support, affixed with it base shell and the film rack that socket-connects, cover on base shell top and lean on bearing, the seat of universal wheel support, be contained in the power drive system in the cavity that base shell and seat constitute, pedestal skeleton and axle and roller, power drive system is by the dynamically supported frame, the train that is contained in the motor of its sidepiece and connects with it, toothed " U " type dish is formed, and on the pedestal skeleton axle is housed, on the axle roller is housed, the garden arc groove of roller is arranged in toothed " U " type dish; The headstock support arm in the seat center stand column hole is inserted in its top and toothed " U " type dish Joint, bottom, the jaw holder that socket-connects with toothed " U " type dish, the head-shield of Joint, axle is equipped with on top at film rack, the end is connected with common magazine folder, with the joining roller of axle, cover on toothed " U " the type dish and a belled with it special magazine on its top, in addition, two pairs of toothed " U " type dishes are meshing with each other.

2, the patient is in place, regulate the height of headstock support arm 7 and film rack 24 according to patient's height, and it is fixing with braking bolt 9,27, with earplug folder and horizontal orbitomeatal line 4 and jaw holder 5, volume point adjusting bolt 1 is benchmark, determine the head putting position, with the fixing health of belt 10, the patient stresses on both hands firm handle 8;
3, seat 12 is rotated to initial position, that is: the side point of toothed " U " dish 6;
4, press permutator K
2, make the circuit and the X-ray machine hand switch K of this device
1Connection is to reach synchronous;
5, press starting button AN
1, motor D
1Work, order about 28 rotations of toothed " U " type dish by train 30, because toothed " U " type dish 28,6 and seat 12 combine as a whole, make toothed " U " type dish 6 when rotating with seat 12, toothed " U " type dish 26 that drive is meshed and card magazine thereon rotate synchronously, when seat turns over certain angle, exposure travel switch K
3Closure, the exposure beginning finishes until photography.
In addition, insert in the common magazine folder, use earplug folder and horizontal orbitomeatal line to make people's front or side face toward common magazine, the former hand switch K of pressing X-ray machine if will install the common magazine of film
1, can realize the cephalometry photography.
The present invention compared with prior art, have simple in structure, easy to use, cheap, practical, The characteristics such as a tractor serves several purposes not only make the oral cavity curved surface layer radiography only need that single exposure can be with denture Tomography imaging impinges upon on the film, and can be with positions such as maxilla, mandibular, maxillary sinus, nasal cavities Show simultaneously. Observe face width, and the design with the x-ray diagnosis scheme of upper part pathology is brought greatest side Just. It is the effective scheme of promoting oral cavity curved surface panorama layer radiography method.
