Description

Oral imaging sensor holding assembly and oral imaging sensor holder used therein

The present invention relates to an oral imaging sensor holding assembly and a holder for an intraoral imaging sensor used therein.

In general, an intraoral sensor is used to take radiographs of an oral structure during dental treatment. The intraoral imaging sensor receives radiation radiated from an external light irradiator. Specifically, the oral cavity imaging sensor is an image sensor that receives radiation transmitted through an oral structure (eg, teeth and alveolar bone) to be imaged, and outputs projection data of the radiation as an electrical signal.

The intraoral imaging sensor must be maintained in a correct position in the patient's mouth so as to correspond to the travel path of the radiation output from the light irradiation device. To this end, medical staff sometimes hold the intraoral imaging sensor with their hands. This method has a problem in that the hand of the medical staff is exposed to the light output from the light irradiation device. In order to keep a medical staff's hand away from the oral cavity imaging sensor, a holder on which the oral cavity imaging sensor is mounted is used.

While one part of the holder is located outside the patient's mouth as a part to be held by the medical staff, the other part must be put into the patient's mouth together with the intraoral imaging sensor. In order for the intraoral imaging sensor to expand the imaging area to the root of the tooth, the medical staff must push the holder deeply toward the root of the tooth. In the process, the patient often feels uncomfortable while the holder collides with the teeth or gums due to the combined structure of the holder and the oral imaging sensor.

Furthermore, the process of coupling the intraoral imaging sensor to the holder is not simple either. At least a plurality of bonding processes are required. This makes the process of coupling the intraoral imaging sensor to the holder cumbersome.

One object of the present invention is to provide an oral imaging sensor holding assembly that can maximize the radiographic area by disposing the oral imaging sensor deep in the tooth direction in the mouth, thereby minimizing the discomfort felt by the patient, and its use It is to provide a holder for an intraoral imaging sensor.

Here, the intraoral imaging sensor IS includes a light detecting unit LR for detecting radiation emitted from a light irradiation device (not shown), and a cable C for transmitting data acquired from the light detecting unit LR to the outside. ) has

The oral imaging sensor holding assembly 100 may be divided into a holder 200 and a restraining shell 300.

The holder 200 is formed in an elongated shape so that the medical staff can hold it in their hands. A restraining sheath 300 is coupled to one end of the holder 200 .

The restraining shell 300 surrounds and restrains the light sensing unit LR. The constraining shell 300 is a hollow body for accommodating the light sensing unit LR.

A detailed configuration of the intraoral imaging sensor holding assembly 100 will be described with reference to FIG. 2 . FIG. 2 is an exploded perspective view of the oral imaging sensor holding assembly 100 of FIG. 1 .

Referring to this figure, the holder 200 may include a shaft 210, a support 230, and a mounting unit 250.

The shaft 210 may be divided into a handle part 211 and a head part 215. The handle portion 211 and the head portion 215 are each made of separate members and may be detachably coupled to each other. The handle part 211 is a part that a medical staff holds by hand, and may be a rod having a generally circular cross section. The head portion 215 may generally have a thinner thickness than the handle portion 211 . The free end portion of the head portion 215 is called a connection portion 217 because the support 230 is connected thereto. In addition, the connecting portion 217 may extend along a direction bent with respect to the extending direction of the handle portion 211 .

The support 230 is a component for supporting the light sensing unit LR. The support 230 is coupled to the light sensing unit LR through the restraining shell 300 . This support 230 has a coupling portion 231 and a support plate 235, the support plate 235 may be arranged to extend laterally with respect to the extension direction of the shaft 210, specifically the connection portion 217 . Thereby, since the connection part 217 and the support plate 235 are arranged in parallel with each other, they do not overlap each other. The support plate 235 may have an area corresponding to the light sensing unit LR. The coupling part 231 may be a part having a tubular shape into which the connection part 217 is fitted and fixed.

The mounting unit 250 is a component for mounting the cable (C). The mounting unit 250 may be coupled to the handle part 211 and the head part 215 . Specifically, the mounting unit 250 may have a bracket part 251 and a fixing part 255 . The bracket portion 251 may be fitted between the handle portion 211 and the head portion 215 . The fixing part 255 may extend from the bracket part 251 to the side of the shaft 210 . The fixing part 255 is formed like a fork in shape, and can fit and fix the cable (C).

The constraining shell 300 may have a substantially rectangular parallelepiped shape corresponding to the shape of the light sensing unit LR. Specifically, the restraining shell 300 may have a first horizontal portion 310 , a vertical portion 330 , and a second horizontal portion 350 .

The first horizontal portion 310 may form the bottom surface of the restraining shell 300 . The vertical portion 330 is a portion extending in a vertical direction from the corner of the first horizontal portion 310 . An insertion slot 340 may be opened through the vertical portion 330 . The second horizontal portion 350 is a portion positioned opposite to the first horizontal portion 310 with respect to the vertical portion 330 . The second horizontal portion 350 is formed with an open entrance 360 allowing the light sensing unit LR to enter in the center.

A coupling relationship between the support 230, the constraining shell 300, and the light sensing unit LR will be described with reference to FIGS. 3 and 4.

First, FIG. 3 is a cross-sectional view of a combined state of the oral cavity imaging sensor holding assembly 100 and the oral cavity imaging sensor IS taken along line III-III in FIG. 1 .

Referring to this figure, the support 230, in particular, the support plate 235 is inserted into the restraining shell 300 through the insertion slot 340 from the side of the vertical portion 330. Here, the insertion slot 340 may be formed in each of the pair of vertical portions 330 . Accordingly, the support plate 235 may be inserted into the insertion slot 340 corresponding thereto, even if it is led to the other side as well as one side of the connection part 217 . This makes it possible to respond simply when the support plate 235 is inserted into the oral cavity, even when the direction needs to be changed depending on whether the left tooth and the right tooth are photographed.

If the light detecting unit (LR) has already been inserted into the restraining shell 300, the medical staff can move the support 230 into the restraining shell 300 with just one operation to establish a relationship between the holder 200 and the oral imaging sensor IS. bonding can be achieved.

When the restraining shell 300 is made of an elastic material, the first horizontal portion 310 and the second horizontal portion 350 elastically support the light sensing unit LR and the support 230 in the above coupled state. put pressure on

Next, FIG. 4 is a conceptual diagram showing the relationship between the light detection unit LR of the intraoral imaging sensor IS of FIG. 1 and the connection unit 217 of the holder 200. Referring to FIG.

Referring to this figure, one end of the connecting portion 217 of the head portion 215 and the restraining sheath 300 may be placed on the same plane P. In this case, the connecting portion 217 and the restraining shell 300 are arranged in parallel in the corresponding plane.

Specifically, the connection unit 217 is located outside the area (sensing area) occupied by the light sensing unit LR in the corresponding plane P. Unlike this, the support 230 is located in an area parallel to the sensing area, that is, an area (projection area) where the sensing area is projected along the central axis of the light sensing unit LR. The connecting portion 217 is located outside the sensing area as well as the plane P′ where the projection area is located. This is according to the design principle in which the support 230, specifically, the support plate 235 (see FIG. 3) does not overlap with the connecting portion 217 but extends to its side.

The usefulness of this design principle will be described with reference to FIG. 5 .

Referring to this drawing, the medical staff may place the head portion 215 in the patient's mouth while holding the handle portion 211 in their hand. As a result, the light sensing unit LR coupled to the head unit 215 through the support 230 and the restraining shell 300 can be positioned in place in the mouth.

In this process, the connection part 217 and further the head part 215 (and the handle part 211) are positioned out of the area occupied by the light sensing unit LR. This is because the support 230 extends to the side of the connection unit 217 and overlaps the light sensing unit LR, but the shaft 210 does not.

Due to this arrangement, within a range in which the connecting portion 217 and further the head portion 215 do not interfere with the tooth T, the light sensing unit LR can be deeply located in a direction toward the patient's tooth root. This enables the light sensing unit LR to obtain an image of the root of the tooth. In the process, since the head part 215 does not interfere with the teeth, the patient may not feel discomfort due to the head part 215 bumping into teeth or gums.

The oral cavity imaging sensor holding assembly and the intraoral imaging sensor holder used therein are not limited to the configurations and operation methods of the above-described embodiments. The above embodiments may be configured so that various modifications can be made by selectively combining all or part of each embodiment.
