Handheld direct digital imaging sensor improved structure

The invention relates to an improved structure of a hand-held direct digital imaging sensing device, in particular to a handheld device capable of reducing discomfort in a patient's mouth and providing X-ray image sensing.

When going to a dentist's office for a first-time or dental examination, the patient often needs to be photographed for X-ray photography of the teeth, so that the dentist can understand the occlusion of the patient's roots and teeth. However, the traditional method of X-ray irradiation requires that after the X-ray is irradiated, the X-ray film is washed out, and the X-ray photograph is observed by the dentist to judge. Not only does this cost a lot of work and cost, but the patient and the dentist also spend a lot of time and effort.

Therefore, a current instant X-ray imaging technique utilizes a direct digital imaging sensor connected to a computer device in the patient's mouth, and X-rays are applied to the local root by the outside of the mouth to make the image appear in direct digital display. After the sensor is sensed, the dentist can watch it directly from the computer screen.

Such an instant-view X-ray image irradiation technique mainly uses a holder of a direct digital imaging sensor as shown in FIG. 1 to extend the direct digital imaging sensor 11 into a patient's mouth, and the patient Hold the gripper to shoot.

The holder of the direct digital display sensor 11 mainly includes a grip handle 10, and a clamping structure 13 having a plurality of gripping arms 12 is disposed at the end portion of the gripping disease, and the gripping arms 12 are respectively located The top of the direct digital display sensor 11 and the periphery of the bottom end thereof are in contact with the direct digital display sensor 11 so that the direct digital display sensor 11 is clamped to the end of the grip handle 10. For the dentist, the direct digital imaging sensor 11 can be placed in the patient's mouth to take a picture by holding the handle 10 as described above.

However, the holder of the direct digital display sensor 11 still has many inconveniences in use; first, since the direction in which the holder holds the direct digital display sensor 11 is fixed, the dentist is shooting differently. In the case of the root of the part, it is necessary to replace the different digital display sensor 11 by replacing the different holders in order to complete the full mouth root.

Furthermore, since the clamping arm 12 of the clamping structure 13 is clamped to the outer periphery of the direct digital imaging sensor 11, the patient's oral cavity is bitten to bite the direct digital imaging sensor 11 except In addition to the range in which the direct digital imaging sensor 11 can be bitten, the thickness of the above-mentioned clamping arm 12 is further increased, making it easier for the patient to bite and increasing the patient's discomfort.

In addition, by fixing the direct digital display sensor 11 by means of clamping, it is also easy to cause the displacement of the direct digital display sensor 11 when the patient is placed inside the patient's mouth, resulting in poor image capturing effect. .
