Embodiment 1

[0026] Such as figure 1 Shown, a kind of digitized dental film machine, comprises the dental film device that links to each other with horizontal support 8 two ends and photographing device, the vertical support 9 that links to each other with horizontal support 8 middle part and the bottom support 10 that links to each other with dual-purpose wheel 11.

[0027] lie in figure 1 The camera device on the right side comprises camera 5, fixed platform 6, filter device 7, control unit, acquisition unit, bluetooth unit and battery unit, camera 5, filter device 7 are located at the top of fixed platform 6, camera The chip machine 5 filters the X-rays through the filter device 7 to reduce the intensity of irradiation to the patient and reduce the damage to the patient. Such as Figure 6 As shown, the fixed platform 6 is provided with a control unit, an acquisition unit, a bluetooth unit and a battery unit, and the control unit adopts an ARM processor with high processing speed. Suc...

Embodiment 2

[0032] Such as image 3 As shown, the horizontal support 8 is provided with an expansion rod 14, and the expansion rod 14 is provided with an air bag or an arc-shaped bracket matching the face. At present, most dental film machines do not have a device to keep the patient's head stable. As the head moves, the angle of the teeth must also change. Therefore, it is very important to ensure the stability of the head position. In this embodiment, the horizontal bracket 8 is extended, and the head is mechanically fixed by the air bag or the arc-shaped bracket of the extension rod 14, so that the stability is higher and the success rate of filming is better.

Embodiment 3

[0034] Such as Figure 4 As shown, the vertical bracket 9 is provided with a fixing clip 15 replacing the bottom bracket 10, and the fixing clip 15 is clamped to the fixing device to take pictures. The vertical support 9 is provided with a height adjustment bolt, which can be adjusted for different heights of patients. The size of the clamping plate 2 is larger than that of the tooth piece 1, and the clamping plate 2 is connected with the tooth piece driving motor 12 by bolts, and the dismounted clamping plate 2 is placed in the disinfectant. Considering the actual conditions of different wards, such as uneven ground, etc., the bottom bracket 10 of the vertical bracket 9 is replaced with a clamp 15 that can be clamped, so that the present invention has a wider application range. Through this embodiment, the scope of application of the present invention is further expanded, not limited to wards with flat ground.

Abstract

The invention relates to a digital dental film machine, which belongs to the technical field of oral cavity or dental devices. The invention solves the instability of non-mechanical fixation and the inefficiency of non-digital control. The present invention includes a dental film device, a photographing device, a supporting device and a driving device, the supporting device is connected to the lower end of the dental filming device and the photographing device through a driving device, and the dental filming device includes a dental film, a clamp, a camera and a light source, and is determined by the camera The position of the dental film; the filming device includes a filming machine, a fixed table, a filter device, a control unit, an acquisition unit, a Bluetooth unit and a battery unit, and the digital control is more efficient; the supporting device includes a horizontal bracket, a vertical bracket and a bottom bracket, mechanically fixed Increase the stability; the driving device includes a dental film drive motor and a film drive motor for angle adjustment. The invention has the advantages of high stability, high success rate and the like.

Description

technical field [0001] The invention relates to a digital dental film machine, which belongs to the technical field of oral cavity or dental devices. Background technique [0002] The dental film machines of the prior art are mainly divided into two categories: the first type is that the dental film machine and the camera are set separately, the patient presses the dental film with his hand, and the doctor operates the film machine. The disadvantages are: (1) non-mechanical fixation Slight shaking of the patient will lead to blurred images and a high failure rate; (2) The camera takes pictures of the patient many times, and a large dose of X-rays will cause serious harm to the patient; (2) The patient presses the dental film with his hands, which is unhygienic It will also allow bacteria to infect the teeth. The second type is the integrated setting of the dental film machine and the camera. The patient controls the handheld device with the aiming device, and the doctor rem...
