technical field

The invention relates to a digital dental film machine, which belongs to the technical field of oral cavity or dental devices.

Background technique

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 remotely operates the camera. It is easy to shoot inaccurate positions, and still cannot get rid of the instability of non-mechanical fixation.

detailed description

The present invention will be further described below in conjunction with drawings and embodiments.

Example 1:

As shown in Figure 1, a digital dental film machine includes a dental film device and a photographic device connected to both ends of the horizontal support 8, a vertical support 9 connected to the middle of the horizontal support 8, and a bottom connected to the dual-purpose wheel 11 bracket10.

The photographing device positioned on the right side of Fig. 1 includes a photographing machine 5, a fixed stand 6, a filtering device 7, a control unit, an acquisition unit, a bluetooth unit and a battery unit, and the photographing machine 5 and a filtering device 7 are arranged on a fixed stand 6 Above, the camera 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. As shown in Fig. 6, a control unit, an acquisition unit, a bluetooth unit and a battery unit are arranged in the fixed platform 6, and the control unit adopts an ARM processor with high processing speed. As shown in Figure 6, the control unit is connected to the camera 3, the light source 4, the camera 5, the acquisition unit and the bluetooth unit, and the bluetooth unit is connected to the host computer. The battery unit adopts a large-capacity lithium battery or an external power supply. 3. The light source 4, the camera 5, the control unit, the acquisition unit and the bluetooth unit are connected.

As shown in Figure 2, the dental film device includes a dental film 1, a clamp 2, a camera 3 and a light source 4. The dental film 1 adopts a uniform standard dental special film, and the dental film 1 is fixed on a side of the clamp 2 near the teeth. Side, that is, the front of the card board 2, the card board 2 is a sterilized waterproof plate made of plastic, the upper part of the card board 2 is provided with a camera 3 and a light source 4, the camera 3 is located in the middle of the upper part of the card board 2, and the light source 4 is located at the camera 3 on both sides. When the brightness in the oral cavity is too low, the light source 4 is turned on to illuminate the teeth. Through the video delivered by the camera 3 to the doctor, the doctor can further determine the position of the teeth.

Supporting device as shown in Figure 1, it comprises the horizontal support 8 that dental film device and photographing device are played supporting role, the vertical support 9 that plays integral support role and bottom support 10, horizontal support 8 and vertical support 9 both Made of strong and lightweight metal material. One end of horizontal support 8 links to each other with the bottom of pallet 2, the other end of horizontal support 8 links to each other with the bottom of fixed table 6, and the two ends of vertical support 9 link to each other with the middle position of horizontal support 8 and bottom support 10 respectively, and bottom support 10 sets There are dual-purpose wheels 11 that can realize orientation and universal direction.

Driving device as shown in Figure 1, it comprises the dental film drive motor 12 that is positioned at the dental film device and horizontal support 8 intersections, the photographing drive motor 13 that is positioned at photographic device and horizontal support 8 intersections. Tooth film drive motor 12 and photographic drive motor 13 adopt the higher digital steering gear of precision.
