Description

Dental unit

The utility model relates to the field of diagnostics, in particular to devices for medical X-ray diagnostics in dentistry.

Dental devices are known for making targeted shots, for example, tube dental x-ray devices (1), in which a monoblock, which includes a steel tank with transformer oil, a high-voltage transformer and an X-ray tube, is mounted on a tripod. An x-ray beam is formed in space by a tube and a diaphragm contained within it.

Such dental devices allow you to perform only aimed shots of individual sections of the upper and lower jaws. Information on the full dental status of the patient can be obtained using the above apparatus, however, for this it will be necessary to perform sequentially about a dozen aimed shots. In this case, the effective equivalent dose to the patient. will be overpriced ...

Dental apparatus is known (2), which allows to obtain a panoramic x-ray image, for example, using orthopantomographic examination, or using the method of intraoral panoramic radiography.

In the case of orthopantomophaphic examination, the x-ray source and the x-ray film cassette are located on the right and left sides of the patient’s head. During exposure, the radiation source and the cassette move synchronously and the radiation passes through the upper and lower jaws of the patient. Panoramic x-ray aerial image is formed at the expense, part 1x

oscillations of the radiation source in the vertical plane and slow circular motion in the horizontal plane.

With intraoral panoramic radiography, the x-ray source is located inside the patient’s oral cavity, and the flexible film cassette is on the outside. When a conical beam of radiation passes through the tissues of the upper and lower jaws, a panoramic image is formed on the film.

It should be noted that the above designs are intended for obtaining only panoramic images.

A device (3) is known that allows both aiming and panoramic shots. In such a dental apparatus in one casing two x-ray tubes of various purposes are installed, the axes of which are at an angle of 90g to each other, as well as a high-voltage transformer designed for both tubes.

The main disadvantage of this dental apparatus is its hardware complexity, since for a full-fledged X-ray examination of the patient’s oral cavity one has to use two X-ray tubes of different designs placed in KQpnyg of this device.; T

The most: bl1 | 1kzM according to the technical essence of the claimed utility model is the dental apparatus (4). The apparatus includes a monoblock emitter

type with an x-ray tube with a hollow remote anode and reverse; output beam, microprocessor. control panel and specialized tripod. The x-ray tube is located in one unit with devices that form the filament and anode voltage of the monoblock. The monoblock of the device is suspended from a specialized tripod, which ensures its movement in height and in the horizontal plane, as well as the rotation of the monoblock around its vertical and longitudinal - horizontal axes. Microprocessor control unit allows you to set the voltage and current of the x-ray tube, and

also exposure time, both in manual and automatic mode. Using the remote control, it is also possible to control the device from an external computer.

However, the use of this dental apparatus allows one to obtain images of only a full panorama of the patient’s teeth, which limits the possibility of an X-ray examination of the patient, since often for a more accurate diagnosis it is necessary to obtain images of individual sections of the upper and lower jaws of the patient.

The proposed utility model solves the problem of creating such a dental apparatus that would make it possible to obtain both panoramic and sighting pictures when using one X-ray tube in it.

To achieve this technical result, a dental apparatus containing a monoblock type emitter with an x-ray tube with a hollow remote anode and a return output beam is secured on a specialized tripod and connected to a microprocessor :; the control panel is additionally equipped with a removable tube mounted on the bottom tube of the x-ray tube, and a hole is made in the tube body opposite the target of the tube anode.

Also, the “m taper” is made in the form of d pipe segments} -prtschrm second pipe segment (centralizer) is attached to the segment; the angle of the x-ray tube on the adoda tube, and its longitudinal axis of symmetry: passes through the center of the hole in the first section of the tube tube. Such a construction of a tube allows more accurate fixation of the irradiation zone on the diagnosed, area of the patient's facial section. . , ..,. ,,

To achieve this goal, firstly, it is necessary to form a certain radiation field only for the studied area of the patient’s oral cavity, (Fig. 5) receiving a radiation beam from the field. - irradiation dialm TRM ZO-bO-mm (this size is sufficient to obtain an image one or two teeth and

adjacent areas of the bone tissue of the jaw). And, secondly, to be able to receive a radiation flux with an irradiation field covering the dentition of the upper and lower jaws with adjacent anatomical structures (Fig. 4).

To obtain an image of one or two teeth and adjacent sections of the bone tissue of the jaw, a special tube is put on the anode of the tube, which allows absorbing radiation emerging from the target. A hole is made in the tube opposite the target, the size of which provides the radiation field necessary for performing targeted images. Thus, in the absence of a tube, the tube generates a panoramic beam of radiation, and in the presence of a tube, an aiming beam.

The proposed utility model is illustrated by the drawings shown in FIG. 1-5.

In FIG. 1 shows a general view of the dental apparatus.

Figure 2 shows the design of the tube.

Fig. 3 shows the construction of a tube with a centralizer.

Figure 4 shows the irradiation field of a panoramic radiation beam.

Figure 5 shows the irradiation field of the aimed beam of radiation.

The dental apparatus (Fig. 1) contains a monoblock type emitter 1 with an x-ray tube 2 installed in it with a hollow remote anode and a return output of the radiation beam. The emitter is mounted on a specialized tripod 3 and connected to a microprocessor control panel 4. (not shown in Fig.). The emitter of monoblock type 1, if necessary, may be equipped with a removable tube 5 mounted on the anode tube of the x-ray tube 2 and fixed on the housing of the emitter 1. The tube 6 (figure 2) is a pipe segment, and the material and wall thickness of the pipe are chosen so so that the x-ray radiation coming out of the x-ray tube on which the tube is worn on the anode is completely absorbed. The tube is mounted on the emitter housing, for example, by means of a flange 7 and a union nut 8. In the housing

..... -: -. - G; :;. .1

tube 6 made a hole 9, which when installing the tube is opposite the target anode of the x-ray tube. For example, for a cutaneous focal length of 100 mm and an irradiation field of 50 mm, the diameter of the hole in the tube should be about 10 mm.

To ensure the convenience of working with the patient during targeted shots, the tube can be made in the form of two pipe segments (Fig. 3), the second pipe segment (centralizer) 10 attached to the pipe segment that is installed on the tube of the x-ray tube at an angle, and its longitudinal axis of symmetry passes through the center of the hole in the first section of the tube tube. This design of the tube allows you to more accurately fix the irradiation zone on the diagnosed area of the maxillofacial region of the patient.

The operation of the dental apparatus is as follows. , R

To obtain a panoramic picture, the anode of the x-ray tube 2, equipped with a hygienic cap, is placed in the patient's oral cavity, and the cassette with the x-ray film is located outside and is pressed tightly to the soft tissues of the face with the palms of the patient.,;

To obtain an aiming shot, it is necessary on the end of the anode tube: 2 to install the tube 5. Fixing it on the monoblock case, for example:: using j with the union nut 8 and flange 7 .; Then the tube with the hole that determines the irradiation field is directed to the diagnosed area, and the cassette with the x-ray film is located in the oral cavity and is pressed behind the investigated part of the jaw. If the tube is made in the form of two pipe segments connected at an angle, the output of the inclined part of the tube is externally attached directly to the diagnosed area.:,

Thus, to conduct a high-quality X-ray examination, a study of the entire dentition is required in combination with additional individual intraoral images. For this, research usually requires a smaller .measure. dental installations. Pr) May May

The utility model allows us to solve such a problem using one dental unit with one x-ray tube installed in it with a special tube.

Such a dental device is structurally simple and cheap and allows you to diagnose in the most radiation safe conditions.
