Description

[Technical field]

[0001] The present invention relates to a mouth corner hook. [Background technology]

[0002] In recent years, the oral cavity of a patient is photographed on a first or second visit, and the photographed image (hereinafter referred to as oral cavity photograph) is displayed on a computer screen to explain how the oral cavity will change before treatment begins. In some cases, the oral cavity photograph is recorded on a dental chart and registered together with the oral cavity photograph in a dental medical equipment database for future identification.

[0003] On the other hand, in recent years, for those who are in a remote location or cannot visit a dentist, it has become common for dentists to remotely diagnose and prescribe medicines after grasping the condition of the oral cavity and information on underlying diseases, under their own responsibility, and when deemed medically possible. There are also systems that use smartphones as a means of photography and communication for making these diagnoses and prescribing.

[0004] Even in such a case, the intraoral photographic image is used. For taking an oral photograph, a mouth hook as disclosed in, for example, Patent Document 1 or Patent Document 2 is generally used. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4486227 [Patent Document 2] JP 2011-30675 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, even if the dental chart is recorded based on a photograph of the oral cavity and then registered together with the photograph in a dental medical equipment database, the collation is done manually, which takes time. Furthermore, conventional mouth corner hooks, such as those in Patent Documents 1 and 2, are primarily intended for widening the mouth (including the lips).

[0007] Furthermore, even if a mouth opener is used to widen the mouth, it is not easy to take a picture of the entire mouth, including the teeth, with a camera such as a smartphone without the image being tilted. Furthermore, even if the mouth is opened with an oral prosthesis, the dentist must follow his / her instructions to restrict the opening to a certain extent. Where to get I don't know if I should take a picture.

[0008] The present invention does not simply open the mouth, but also expands the mouth, including the teeth. Finger Fixed part To obtain a mouth corner hook capable of accurately and easily photographing an oral cavity and also capable of identifying someone and where the oral cavity photograph is taken. [Means for solving the problem]

[0009] The mouth corner hook according to the present invention is a mouth corner hook having a pair of mouth corner hooks for widening the mouth sideways and a substantially U-shaped arm connected to the pair of mouth corner hooks, The left and right corner hooks are, The outer tsuba, which is the outside of the mouth, and the inner tsuba, which is the inside of the mouth side guard and a clamping member that connects the outer flange and the inner flange and is clamped between both flanges, The arm includes: A horizontal bar is connected across the left and right sides of this arm, The horizontal bar has a slider that slides left and right, and the slider has a vertical bar of a predetermined length. one end is fixed to the Effect of the Invention

[0010] As described above, according to the present invention, the mouth is not simply opened, but also the designated teeth are included.

[Figure 11] FIG. 2 is a detailed explanatory diagram (2) of the mouth corner hook 100 of the embodiment 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] <Embodiment 1> Fig. 1 is a perspective view of the mouth angle hook 10 according to the first embodiment. Fig. 2 is a view of the mouth angle hook 10 of Fig. 1 as seen from above (direction A). Fig. 3 is an enlarged view of a part of Fig. 2. The material of the mouth angle hook 10 is a synthetic resin material such as plastic, polycarbonate, polyethylene, or polypropylene.

[0013] As shown in Fig. 1, the mouth corner hook 10 of the present embodiment 1 has a two-dimensional barcode (QR code (registered trademark)) printed or leveled on the right outer flange 20 and the left outer flange 22. The right side of this QR code (registered trademark) is called the right side personal authentication identification code 12, and the left side is called the left side personal authentication identification code 14.

[0014] In addition, the lower parts of the pair of left and right jaw hooks (outer mouth right flange 20, outer mouth left flange 22) of this jaw hook device 10 are connected (or may be integrally molded) by a substantially U-shaped arm 24. This arm is also made of a synthetic resin material such as elastic plastic, polycarbonate, polyethylene, or polypropylene.

[0015] The plate portion on which the above-mentioned right-side personal authentication identification code 12 is provided is referred to as the right-side personal authentication identification code plate portion 16 (also referred to as the identifier portion), and the plate portion on which the left-side personal authentication identification code 14 is provided is referred to as the left-side personal authentication identification code plate portion 18 (also referred to as the identifier portion). Furthermore, the plate portions are provided with vertical convex portions. These vertical convex portions are for pinching with the fingers and further spreading the opening horizontally. The right side is referred to as the right-side vertical convex portion 26, and the left side is referred to as the left-side vertical convex portion 28.

[0016] 1, the right side personal authentication identification code 12, the right side personal authentication identification code plate part 16, the left side personal authentication identification code 14, and the left side personal authentication identification code plate part 18 are shown enlarged. The oral hook 10 of the present embodiment 1 has a width of about a mm (120 mm to 150 mm: preferably 135 mm), a length from a horizontal line (not shown) passing through the upper end of the extraoral right flange 20 and the upper end of the extraoral left flange 22 to the end of the arm 24 is 80 mm to 100 mm (preferably about 90 mm), and there are medium and small sizes.

[0017] On the other hand, when using the lip hook 10, hold the arm 24 near the right-side personal authentication identification code plate portion 16 and the left-side personal authentication identification code plate portion 18 with your hand and push it inward against the spring force to reduce the width dimension of the lip hook, and then insert it into the patient's mouth and hook it on both sides of the corners of the mouth (lips).

[0018] When the hand is released from the arm 24, the left and right corner hooks move in the opening direction due to the restoring force of the spring arm, and the corners of the mouth are pushed apart to the left and right. This makes it possible to examine, treat, and photograph the inside of the oral cavity.

[0019] In other words, the barcode plate parts (right personal authentication identification code plate part 16, left personal authentication identification code plate part 18) with QR codes (registered trademark) are integrated or connected to the left and right brim parts (extraoral right brim part 20, extraoral left brim part 22), so that the photographer (nurse, caregiver, remote person (person requesting examination), etc.) will take a photograph including the right personal authentication identification code 12 and the left personal authentication identification code 14, and can take a photograph so that the teeth fit in with the lips spread horizontally and vertically (entire mouth).

[0020] These barcodes on both the left and right sides contain the patient's identification information (patient address, name, age, gender, telephone number, health insurance card number, My Number number, information about the dentist who provided the palate hook, etc.), so for example, if an image of the oral cavity is sent to a center over a communications network and stored there, the barcode (QR code (registered trademark)) on the captured image can be analyzed to determine who the patient is and where they are from.

[0021] Furthermore, in the mouth corner hook 10 of the present embodiment 1, the right side personal authentication identification code plate portion 16 and the left side personal authentication identification code plate portion 18 are provided with vertical convex portions. These vertical convex portions are for pinching with the fingers to further open the mouth horizontally. The right side is called the right side vertical convex portion 26, and the left side is called the left side vertical convex portion 28.

[0022] The right and left personal authentication identification code plate parts 16 and 18 preferably have a length and width (b) of about 10 mm to 40 mm (for example, 15 mm or 24 mm) and a thickness of 2 mm to 4 mm (for example, 3.5 mm).

[0023] Therefore, the right side vertical convex portion 26 and the left side vertical convex portion 28 can be pinched and spread apart with the fingers, so that the teeth can be photographed even at their innermost portions.

[0024] As shown in FIG. 2, the mouth corner hook 10 of the present embodiment 1 is formed in a pair of right and left mouth corner hook portions 10a and 10b (either one is acceptable).

[0025] The right side mouth hook 10a is molded by sandwiching a roughly crescent-shaped member (hereinafter, referred to as the right side crescent-shaped member 34) between the intraoral right flange 30 and the extraoral right flange 20. The thickness "m: see FIG. 3" of this right side crescent-shaped member 34 is about 2 mm to 4 mm (see 34a (for example, 3.5 mm)), and the width is about r (8 mm to 1.5 mm: preferably 9 mm) as shown in FIG. 3. The intraoral right flange 30 (external right flange 20) has a thickness of about 2 mm to 4 mm (for example, 3.5 mm). This intraoral right flange 30 (external right flange 20) may be curved or may be inclined at a slight angle (3 degrees to 8 degrees from the horizontal axis) from 34a in a straight line. In addition, the R (radius) of the outer edge of the intraoral right flange 30 (extraoral right flange 20) is about 18 mm to 22 mm (e.g., 20 mm), the R (radius) of the inner edge is about 13 mm to 18 mm (e.g., 16 mm), and the difference between the inner edge and the outer edge is a maximum of about 10 mm (e.g., 8 mm).

[0026] On the other hand, the left side buccal hook 10b is similarly molded by sandwiching a roughly crescent-shaped member (hereinafter referred to as the left crescent-shaped member 36) between the intraoral left flange 32 and the extraoral left flange 22. The thickness of this left crescent-shaped member 36 is also about 2 mm to 4 mm (see 34b).

[0027] As shown in FIG. 2, the intraoral right flange 30 and the intraoral left flange 32 are curved inward, while the extraoral right flange 20 and the extraoral left flange 22 are straight (they may be curved inward slightly).

[0028] The right-side personal authentication identification code plate portion 16 is connected to a right-side outer flange 20, and the left-side personal authentication identification code plate portion 18 is connected to a left-side outer flange 22 (they may be integrally molded).

[0029] The right side buccal hook 10a (the left side buccal hook 10b is similar and will not be described) will be described with reference to FIG. The right-side personal authentication identification code plate portion 16 is connected to the right-side outer flange 20 by a right-side pin 36 (also called a convex pin) (it may be fixed with an adhesive). The diameter of the right-side pin 36 (left-side pin) is preferably about 3 mm to 5 mm (for example, 4 mm).

[0030] The right-side vertical protrusion 26 of the right-side personal authentication identification code plate part 16 preferably has a width d of about 3 mm to 4 mm. Also, part (f) of the right-side personal authentication identification code 12 of the right-side personal authentication identification code plate part 16 is printed or affixed at a distance (g) of 2 mm to 3 mm from the right-side vertical protrusion 26 (it is preferable to print on white).

[0031] Moreover, the distance from the left end of the right-side pin 36 to the left end of the right-side personal authentication identification code plate portion 16 is approximately "k" mm (5 mm to 8 mm).

[0032] Fig. 4 is a perspective view of the right side hook 10a. Fig. 4 shows an example in which the hook is connected to the right side outer tsuba 20 by the right side pin 36 (36a, 36b). The effect of connecting the hook to the right side pin 36 (36a, 36b: convex) will be described.

[0033] A hole (not shown: diameter is about 3 mm to 5 mm (preferably about 0.1 mm to 0.3 mm smaller than this) for fitting the right pin 36 (36a, 36b) is formed through the right pin 36 (36a, 36b). In addition, these holes (upper hole, lower hole) are provided at positions 5 mm to 9 mm (preferably 6 mm) above and below the center on a vertical line (not shown) that passes at a right angle (may be off by about 1 mm or 2 mm) to a horizontal line Li (see Figure 9) that passes through the center of the right side outer flange 20 (may be off by about 1 mm or 2 mm).

[0034] When using the lip angle hook 10, the arm 24 near the right side personal authentication identification code plate portion 16 and the left side personal authentication identification code plate portion 18 is held in the hand and pushed inward against the spring force to reduce the width dimension of the lip angle hook, and then inserted into the patient's mouth and hooked on both sides of the corners of the mouth (lips). However, since the present embodiment has right side lip angle hook portion 10a with a QR code (registered trademark) (the left side lip angle hook portion 10b is similar and therefore not described here), it may get in the way and be difficult to insert.

[0035] This can be solved by inserting the device into the patient's oral cavity, hooking it onto both sides of the corners of the mouth (lips), and then connecting the right-side personal authentication identification code plate portion 16 with the right-side pins 36 (36a, 36b).

[0036] <Other embodiments> FIG. 5 is a perspective view of an outer-mouth right-side flange 20 and a right-side personal authentication identification code plate portion 16 with a QR code (registered trademark) integrally molded.

[0037] 6 is a perspective view of an example in which a right-side personal authentication identification code plate 17 (the left side is similar and therefore omitted) with a one-dimensional barcode 13 is used instead of the right-side personal authentication identification code plate part 16 with a QR code (registered trademark). This right-side personal authentication identification code plate 17 (approximately 15 mm to 30 mm in length and 8 mm to 15 mm in width) is connected to the outer-mouth right-side brim 20 by a right-side pin 36 (36a, 36b) (it may be integrally molded).

[0038] If both the left and right sides are barcode plates with one-dimensional barcodes 13, the width will be approximately the same as the left and right outer flanges (20, 22).

[0039] In addition, when photographing the mouth corner hook in Figure 6 with a photographing device such as a smartphone or camera, a horizontal line is displayed on the screen of the photographing device, and the horizontal bars near the center of the one-dimensional barcodes on the left and right can be easily aligned with this horizontal line. In addition, since the width is narrower than that of the QR code (registered trademark), it is easy to photograph the entire mouth with the photographing device. 7 is an explanatory diagram of an example of use of the mouth corner clasp 10 of this embodiment, which is an example of remote dental treatment, etc. The mouth corner clasp 10 of this embodiment is placed in the mouth of a patient. Then, an image is taken with a camera 42 of a smartphone (hereinafter referred to as a smartphone 40) or a camera 50 connected to a personal computer 60. As shown in FIG. 7 of the smartphone 40 or the personal computer 60, an image of the cheiloscope 10 with a QR code (registered trademark) attached to the patient's mouth (hereinafter referred to as an oral cavity photo 10A with an identifier) ​​is displayed on the screen.

[0040] The photograph of the oral cavity with the identifier 10A is transmitted to an authentication site 80 (server) via a communication network (dedicated line, Internet line, etc.). When transmitting, a screen for inputting patient identification information (name, telephone number, email address, age, sex) (not shown) is displayed, and the patient identification information is added to the photograph of the oral cavity with the identifier 10A and transmitted.

[0041] The authentication site 80 stores the identified cheilogram oral cavity photograph 10A in memory (including patient identification information), and determines characteristic points of the mouth shape, teeth shape, arrangement, etc. (collectively referred to as tooth information below) contained in the identified cheilogram oral cavity photograph 10A, and stores these as authentication information.

[0042] If an image of the mouth taken with the mouth open (hereinafter referred to as the test image) is sent from a public institution via a communication network for some reason, feature points such as the shape of the mouth, the shape and arrangement of the teeth (hereinafter referred to as the test image features) are obtained from the image of the mouth open (preferably using a palate hook) contained in the test image, and these test image feature points are compared with the feature points of the authentication information to determine whether they are the same person's tooth information. If they are determined to be the same, they are compared with the patient identification information (QR code (registered trademark) or one-dimensional barcode) contained in the authentication information to detect who is where (address, phone number, name, age, sex, information on the dentist who provided the palate hook, etc.).

[0043] The above-mentioned identifier-added oral cavity photograph 10A is sent to a dentist terminal (including a server and a personal computer) not shown, and the dentist writes the necessary information (number of teeth, presence or absence of cavities, arrangement, various views, etc.) on the dental chart shown in Figure 8. The patient ID code is written on the dental chart.

[0044] It is preferable to operate the dentist's terminal to associate and register the identifier-attached oral cavity photograph 10A. Therefore, if the dental chart (with the oral cavity photograph 10A) is included in the image to be examined and transmitted, it can be compared with the dental chart (with the oral cavity photograph 10A) stored in advance, and the accuracy of comparison can be further improved.

[0045] <Embodiment 2> When a dentist takes a photo of the corners of the mouth, there are cases where the dentist wants to take a photo of the whole mouth, both sides, and the back teeth. However, when taking a photo remotely, the patient does not know which area is to be taken, and the dentist may be confused when instructing which area is to be taken. The second embodiment solves this problem.

[0046] Fig. 9 is a perspective view for explaining the mouth corner hook 100 of the embodiment 2. Figs. 10 and 11 are detailed explanatory views of the mouth corner hook 100 of the embodiment 2.

[0047] The mouth corner hook 100 of the second embodiment has a horizontal bar 112 with a slider 114 with a vertical bar 116 connected to the arm 24. The mouth corner hook 100 is made of a synthetic resin material such as plastic, polycarbonate, polyethylene, or polypropylene.

[0048] As shown in Figures 9, 10(a) and 10(c), the surface of this vertical bar 116 (width 3mm to 5mm, length 30mm to 55mm) is colored with color 116. Although not shown, the horizontal bar 112 has graduations (5mm, 1cm intervals) on the left and right ends.

[0049] For example, integers such as "1", "2", "3", "4", etc. are engraved at intervals of, for example, 1 cm from the center (reference position) of both ends (inner end or outer end) of the horizontal bar 112. It is preferable to engrave "-1", "-2", "-3", "-4", etc. on the right side, and "+1", "+2", "+3", "+4" on the left side. Furthermore, scale marks may be engraved at 1 cm intervals along with these numbers, with 5 mm scale marks engraved between each cm unit. It is preferable to engrave "0" at the reference position.

[0050] Alternatively, scale marks are engraved on either side of one end (inner end or outer end) of the horizontal bar 112, such as 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, etc., with 5 mm scale marks engraved between each cm unit.

[0051] As shown in FIG. 9, pins 113 (113A, 113B) are provided at the ends (left and right) of the horizontal bar 112, and the centers of these pins 113 (113A, 113B) are located approximately J mm (20 mm to 50 mm: for example, 40 mm) below a horizontal line Li that passes through the center of the outer right flange 20 of the right corner hook 10a and the center of the outer left flange 22 of the left corner hook 10b.

[0052] As shown in Fig. 10(a), the slider 114 is slidable left and right (see Fig. 10(c)). Furthermore, as shown in Fig. 10(b), pins 113 (113A, 113B) are detachably provided at the ends (left and right) of the horizontal bar 112 (they may be fixed, but it is preferable that they are detachable). The pins 113 are preferably plastic drive pins or screws.

[0053] 11 (showing the left side), horizontal bar 112 (preferably straight, but may be slightly curved) is arranged by support 115 so that the distance between it and arm 24 is about Q1 (for example, 10 mm to 30 mm). Q2 is preferably 5 mm to 10 mm, Q3 is 70 mm to 120 mm, and Q4 is preferably about 5 mm to 10 mm.

[0054] The connection is made by left pin 113B (right side is 113A: a plastic drive pin, screw is preferable). Also, holes 114 (for example, diameter of about 2 mm to 4 mm (for example, 3 mm)) are molded at positions (on both the left and right) of arm 24 about J mm (20 mm to 50 mm: for example, 40 mm) downward from horizontal line Li (not shown) passing through the center, while a convex left stop pin 113B' (similar to the right side) is molded on the surface side of support 115 that contacts arm 24, to connect and fix to arm 24.

[0055] The material of the horizontal bar 112 may be, for example, polyamide resin (nylon 66) so that it can be bent.

[0056] That is, even if the arm 24 is placed on the chin, the length of the support 115 is about Q1 (for example, 10 mm to 30 mm), so that the vertical bar 116 does not hit the lips even when the slider 115 (concave shape) is moved.

[0057] In addition, since the connection is made by the left pin 113B (113A on the right side), as in the first embodiment, the arm 24 of the lip angle hook 100 can be held by hand and pushed inward against the spring force to reduce the width dimension of the lip angle hook, and then inserted into the patient's oral cavity to hook both sides of the corners of the mouth (lips). After releasing the arm 24 and attaching it, the left or right pillar of the horizontal bar 112 (with pillars 113 (left and right)) with the slider 114 with the vertical bar 116 can be connected to the arm 24 by the pin (left side stop pin 113B' (same for the right side)), and then the right or left pillar can be connected by the pin.

[0058] Therefore, when the slider 114 is moved to the position instructed by the doctor (for example, a few centimeters to the right), the vertical bar 116 will come to rest on the tooth at that position, allowing the imaging device to capture an image including the left or right QR code (registered trademark).

[0059] If a captured image with a QR code (registered trademark), for example an image of an oral cavity, is sent to a center via a communications network and stored, the barcode (QR code (registered trademark)) on the captured image can be analyzed to determine who the person is and where they are from. In addition, the vertical and horizontal sizes of the right or left personal authentication identification code plate section are preferably approximately 8 mm, 12 mm, 13 mm, 22.5 mm, 24.5 mm, or 28.5 mm when a QR code (registered trademark) is printed or affixed.

[0060] The pins (36, 38, 113) may be plastic lock pins, rivet pins, or the like. Furthermore, the left and right identifier portions (e.g., 16, 18) may be different in size. For example, the right side may be smaller, measuring 10 mm×10 mm, and the left side may be larger, measuring about 20 mm. Therefore, it can be adapted to suit the condition of the left and right cheeks and lips.

[0061] The QR code (registered trademark) or one-dimensional barcode is preferably printed by letterpress printing, offset printing, gravure printing, a 3D printer, a laser marker printer, a thermal printer, or the like.

[0062] Although the support pillar is exemplified as a rectangular pillar, it may be a round pillar (including an ellipse). Furthermore, the personal authentication identification code plate portion may be a circle or an ellipse. [Explanation of symbols]
