Description

[Technical Field]

[0001] The present invention relates to a mobile colposcope device for early diagnosis of cervical cancer, and more particularly to a mobile colposcope device for early diagnosis of cervical cancer that can easily perform visual cervical cancer screening using a mobile colposcope without environmental constraints, not just in a hospital. [Background technology]

[0002] Cervical cancer is the second most common cancer in women worldwide, accounting for 23% of all cancers in women, of which cervical cancer accounts for 90-95%.

[0003] When cervical cancer is discovered early (at the precancerous stage), treatment and prognosis are good, but if it progresses to cancer, the survival rate drops to within five years. Therefore, women need to undergo cervical cancer screening at annual intervals to ensure early detection.

[0004] Currently, cervical cancer testing includes diagnostic methods such as cytology, colposcopy, and tissue biopsy, as well as treatment methods such as local destructive and surgical therapy, and chemotherapy and radiation therapy. Recently, self-diagnosis kits that allow women to test for their own diseases have also been released.

[0005] A typical screening method, colposcopy, is a method of examining the cervix through a specially designed magnifying lens. It allows direct visual confirmation of various signs of cervical abnormalities according to a set of diagnostic criteria, and allows tissue biopsy and treatment of suspected areas. This method is highly accessible in developed countries, but in developing countries such as Asia, South America, and Africa, where approximately 80% of cervical cancer cases occur, early diagnosis of cervical cancer is difficult due to equipment issues.

[0006] [Patent Document 1] Korean Patent Publication No. 2015-0002755 (2015.07.13) [Patent Document 2] Korean Patent Publication No. 2008-0002974 (2008.07.30) Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been invented to solve the above-mentioned problems, and its purpose is to provide a mobile colposcope device for early diagnosis of cervical cancer that can diagnose cervical cancer early using a relatively easy-to-have device such as a smartphone equipped with a camera for taking pictures. [Means for solving the problem]

[0008] To achieve the above object, the mobile colposcope device for early diagnosis of cervical cancer according to the present invention comprises an insertion section which is inserted into a woman's vagina and has a viewing hole at one end which contacts the uterus, and which is provided with an imaging path which communicates with the viewing hole; an imaging section which is installed in the insertion section so as to be able to photograph the cervix through the imaging path; and an illumination section which is installed on the imaging path of the insertion section and which irradiates illumination light onto the cervix through the viewing hole.

[0009] It is preferable that the insertion part is formed with an injection port so that the air on the imaging path can be circulated to the outside to prevent condensation and fogging on the imaging part, or so that the insertion part is connected to the imaging path to inject an examination solution when examining the cervix.

[0010] It is preferable that the illumination unit includes a light source installed in the insertion unit to irradiate illumination light onto the imaging path, and a light guide unit to guide the illumination light generated from the light source toward the viewing hole.

[0011] It is desirable to provide an optical unit that is installed on the imaging path and blocks reflected light that is reflected on the surface of the cervical tissue and flows into the fluoroscopy hole, while passing only illumination light that passes through the surface of the cervical tissue and is reflected inside the cervical tissue toward the fluoroscopy hole.

[0012] The photographing unit is configured to mount a smartphone equipped with a photographing camera, and can support the smartphone so that the photographing camera faces the viewing hole so that the photographing camera can photograph the cervix through the viewing hole.

[0013] It is desirable that an insertion space is formed at the other end of the insertion portion, into which the smartphone can be inserted, and a setting port is formed at a position opposite the viewing hole, into which the photographing lens of the photographing camera can be set.

[0014] The imaging unit is either an endoscope camera or a hyperspectral camera.

[0015] The viewing hole is preferably formed so as to be inclined at a predetermined angle with respect to the center line of the length of the imaging path.

[0016] The device may further include an expansion unit that expands the vaginal space when the insertion portion is inserted into the vagina.

[0017] The expansion unit has a hollow formed therein so that one end of the insertion portion can be inserted, and includes a first expansion member and a second expansion member that are installed so that they can rotate relative to each other in directions that move away from each other based on the center of the hollow, and a plurality of handle members formed on the expansion unit so that an operator can grasp them to rotate the expansion members.

[0018] The insertion portion may have a guide groove extending a predetermined length along the insertion direction into the vagina, and the expansion unit may have a guide protrusion formed on one of the first expansion member and the second expansion member so as to be pulled into the guide groove.

[0019] The insertion portion is preferably formed to have an inner diameter that decreases toward the viewing hole so that scattered light emitted from the light source and scattered by an inner wall surface can be incident on cervical tissue.

[0020] The optical unit is characterized by including a linear polarizer (LP) installed on the imaging path to form parallel polarization (P-Polarization) of light output from the light source, and a quarter-wave plate (1 / 4λ retarder (QWP) installed on the imaging path behind the linear polarizer based on the output direction of the light to form circular polarization of the light that has passed through the linear polarizer.

[0021] The insertion section may further include a communication section that is connected to the injection port and is formed circumferentially along the inner surface of the insertion section, and at least one ejection pipe that extends from the communication section along the imaging path toward the viewing hole side and that ejects outside air that has flowed in through the injection port at the end of the viewing hole or ejects a chemical toward the viewing hole side. [Effects of the Invention]

[0022] The mobile colposcope device for early diagnosis of cervical cancer according to the present invention can be used for cervical cancer screening simply and easily without any environmental restrictions, not just in hospitals, and has the effect of enabling women to diagnose cervical cancer early.

DETAILED DESCRIPTION OF THE INVENTION

[0024] A mobile colposcopy device 10 for early diagnosis of cervical cancer according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The present invention may be modified in various ways and may have various forms, but specific embodiments will be illustrated in the drawings and described in detail herein. However, this is not intended to limit the present invention to the specific disclosed form, and it should be understood that the present invention includes all modifications, equivalents, and alternatives falling within the spirit or technical scope of the present invention. Like reference numerals are used to refer to like elements throughout the drawings. In the accompanying drawings, the dimensions of structures are exaggerated to clarify the present invention.

[0025] Terms such as "first," "second," etc. may be used to describe various components, but the components should not be limited by these terms. These terms are used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the scope of the present invention.

[0026] The terms used in this application are merely used to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly dictates otherwise. In this application, terms such as "comprise" or "have" are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the presence or additional possibility of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0027] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which this invention pertains. Terms, such as those commonly used and predefined, should be interpreted to have a meaning consistent with the meaning they have in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined in this application.

[0028] 1 and 2 show a first embodiment of a mobile colposcopy device 10 for early diagnosis of cervical cancer according to the present invention.

[0029] Referring to the drawing, the mobile colposcope device 10 for early diagnosis of cervical cancer includes an insertion unit 100, a photographing unit 200, and an illumination unit 300.

[0030] The insertion part 100 is inserted into the woman's vagina, and has a viewing hole 110 formed at one end that contacts the uterus, and an imaging path 130 that communicates with the viewing hole 110 is provided inside.

[0031] The imaging path 130 extends in the front-rear direction, and the rear part of the insertion part 100 is open so as to be able to communicate with the imaging part 200 .

[0032] Here, the insertion unit 100 is formed in a tapered shape such that the inner diameter decreases from the imaging unit 200 toward the fluoroscopic hole 110, making it easier for the examiner to insert the insertion unit 100 into the vagina. In addition, the tapered shape of the insertion unit 100 reduces the inner diameter of the imaging path 130, so that the illumination light irradiated from the illumination unit 300 is not directly irradiated but becomes indirect illumination due to scattering light, thereby reducing reflection on the surface of the cervical tissue.

[0033] The viewing hole 110 is formed to be inclined at a predetermined angle with respect to the longitudinal center line of the imaging path 130. It is preferable that the examiner examines the cervix by bringing the inclined viewing hole 110 into contact with the cervix.

[0034] The fluoroscopic hole 110 tilted at a predetermined angle secures the imaging path 130 by pushing out cervical tissue 900 that obstructs the imaging path 130 when examining the cervix, which is formed differently for each individual due to anatomical differences between individuals.

[0035] Furthermore, the insertion section 100 has an injection port 120 formed on the outer circumferential surface so as to be in communication with the imaging path 130 .

[0036] Air on the imaging path 130 is circulated to the outside through the inlet 120, thereby preventing condensation and fogging from occurring in the imaging unit 200. If condensation and fogging occurs in the imaging unit 200, the air flowing in from the outside through the inlet 120 is discharged through the viewing hole 110 inclined at a predetermined angle, thereby allowing the air to circulate.

[0037] The position and size of the injection port 120 are not limited.

[0038] The photographing unit 200 is for mounting the smartphone 700 equipped with a photographing camera 710, and is installed at the rear end of the insertion unit 100 and mounts the smartphone 700 equipped with the photographing camera 710 in the photographing unit 200. A lead-in space 210 into which the smartphone 700 can be inserted is formed on the rear surface of the photographing unit 200. The lead-in space 210 is formed to correspond to the cross-sectional area of ​​the smartphone 700 so that the smartphone 700 can be pushed and fitted.

[0039] The lead-in space 210 is formed with a setting opening 211 at a position facing the viewing hole 110 on the rear surface of the photographing unit 200, into which a photographing lens of a photographing camera 710 provided on the smartphone 700 can be set.

[0040] The setting hole 211 is formed at a position opposite to the viewing hole 110, and is formed with an area corresponding to the lens of the photographing camera 710 of the smartphone 700 so that the lens of the photographing camera 710 can be inserted.

[0041] Here, the photographing unit 200 supports the smartphone 700 such that the photographing camera 710 faces the viewing hole 110 so that the photographing camera 710 can photograph the cervix through the viewing hole 110 .

[0042] Although not shown in the drawings, the photographing unit 200 includes a first adjustment member, a second adjustment member, and a spring member.

[0043] When the smartphone 700 is pulled into the retraction space 210, the smartphone 700 is attached to the first adjustment member, and the second adjustment member, which can adjust the length and width by the spring member, fixes the smartphone 700 attached to the first adjustment member.

[0044] The illumination unit 300 includes a light source 310 and a light guide 320 .

[0045] The light source 310 is installed at the bottom of the insertion section 100 and irradiates illumination light onto the imaging path 130 .

[0046] The light guide 320 is installed inside the insertion part 100 to guide the illumination light generated by the light source 310 toward the viewing hole 110 .

[0047] The light guide 320 is provided with a reflector that is installed on the inner wall surface of the insertion part 100 facing the light source 310 and can reflect the light generated from the light source 310 toward the viewing hole 110.

[0048] On the other hand, although not shown in the drawing, the light guide 320 may be an optical fiber, which has one end installed in the light source 310 and the other end installed inside the insertion part 100 and facing the viewing hole 110, and guides the light generated by the light source 310 and transmits it to the viewing hole 110.

[0049] Here, a plurality of optical fibers are provided, and one end of each optical fiber is bundled and connected to the light source 310. The other ends of the optical fibers are separated and inserted into the insertion part 100, and are preferably arranged to be spaced apart from each other and to face the viewing hole 110.

[0050] A second optical coupler such as a lens may be used when the light emitted from the light source 310 is input to one end of the optical fiber, and the light input to one end of the optical fiber is transmitted along the optical fiber to the other end, allowing it to be emitted from the viewing hole 110 side.

[0051] The insertion unit 100 allows the viewing hole 110 to be in perfect contact with the surface of the cervix to prevent the inflow of external illumination light such as fluorescent light. That is, only the intended illumination of the illumination unit 300 is irradiated onto the cervix, so that the illumination conditions for irradiating the cervix are constant.

[0052] In this way, images acquired under the same constant shooting conditions have the effect of reducing distortion when analyzing diseases using artificial intelligence later.

[0053] In the first embodiment, the insertion unit 100, the photographing unit 200, and the lighting unit 300 are manufactured by 3D printing, which makes them easier to manufacture and use.

[0054] 3-4 show a mobile colposcopy device 10 for early diagnosis of cervical cancer according to a second embodiment.

[0055] Elements performing the same function as in the previously shown figures are designated by the same reference numerals.

[0056] Referring to the drawings, the photographing unit 200 is installed at the rear end of the insertion unit 100 facing the viewing hole 110, and an endoscopic camera facing the viewing hole 110 is applied, and the mobile colposcope device 10 for early diagnosis of cervical cancer further includes an optical unit 400 installed on the photographing path 130.

[0057] FIG. 9 shows the principle of the polarization system of the optical unit 400 according to the second embodiment.

[0058] The optical unit 400 blocks reflected light that is reflected by the surface 910 of the cervical tissue 900 and enters the viewing hole 110, and allows only illumination that passes through the surface 910 of the cervical tissue 900 and is reflected inside 920 of the cervical tissue 900 to the viewing hole 110 to pass through.

[0059] The optical section 400 is composed of a linear polarizer 410 and a quarter-wave plate (1 / 4λ retarder) 420 .

[0060] The linear polarizer 410 is first installed on the imaging path 130 to form parallel polarized light 430 from the light source 310 .

[0061] The quarter-wave plate 420 is installed on the imaging path behind the linear polarizer 410 based on the light output direction, and converts the light passing through the linear polarizer 410 into left-handed circularly polarized light 431.

[0062] When unpolarized light emitted from the light source 310 passes through the linear polarizer 410, parallel polarization 430 occurs, and when the parallel polarization 430 light passes through the quarter-wave plate 420, left-handed circular polarization 431 occurs.

[0063] The light that is specularly reflected from the surface 910 of the cervical tissue 900 and returns is right-handed circularly polarized light 433. When the right-handed circularly polarized light 433 passes through the quarter-wave plate 420, it becomes vertically polarized light 432, and therefore cannot pass through the linear polarizer 410 and reach the imaging unit 200.

[0064] Similarly, when light passing through the linear polarizer 410 and the quarter-wave plate 420 is reflected by the interior 920 of the cervical tissue 900, the reflected light contains information about the interior 920 of the cervical tissue 900, passes through the quarter-wave plate 420 first, and then the linear polarizer 410, and reaches the imaging unit 200 as parallel polarized light 430.

[0065] As a result, light reflected from the surface 910 of the cervical tissue 900 cannot enter the imaging unit 200, and only the remaining light reflected from the interior 920 of the cervical tissue 900 passes through, thereby eliminating surface reflections that interfere with data analysis and diagnosis.

[0066] Meanwhile, FIGS. 5 and 6 show a mobile colposcope device 10 for early diagnosis of cervical cancer according to a third embodiment.

[0067] Elements performing the same function as in the previous figures are designated by the same reference numerals.

[0068] Referring to the drawings, the photographing unit 200 is installed at the rear end of the insertion unit 100 facing the viewing hole 110, and is characterized by comprising a hyperspectral camera 800 facing the viewing hole 110, and an optical coupler 500 installed between the hyperspectral camera 800 and the insertion unit 100.

[0069] The optical coupler 500 is a connecting component including a lens, and adjusts the focus of the hyperspectral camera 800 so that the image of the cervix is ​​accurately focused on the image sensor of the hyperspectral camera 800.

[0070] The hyperspectral camera 800 captures several or more images with the same field of view, each captured at a different wavelength of light. When examining the cervix, applying acetic acid to the cervix causes abnormal areas to turn white. This is because the application of acetic acid causes certain wavelengths of light to be reflected less, while other wavelengths are reflected more.

[0071] An object that appears blue absorbs light other than blue and reflects blue light, which is why our eyes and cameras perceive it as blue. If a certain operation changes this color to red, it means that the degree of reflection and absorption for each wavelength has changed. Existing cameras only have three types of pixels (RGB), so they cannot accurately analyze the response of the cervix to light of various wavelengths.

[0072] However, if there were a hyperspectral camera 800 capable of capturing images at, for example, 16 wavelengths, color changes could be analyzed more precisely, yielding more information. Meanwhile, by using images for each wavelength from the hyperspectral camera 800, the concentration of various light absorbers in the cervix could also be measured indirectly. That is, if there are many light absorbers that absorb light well at a particular wavelength, the amount of light at that wavelength reflected back to the camera would be reduced (Beer-Lambert Law). Because the absorption spectra of light absorbers primarily distributed in the human body are well known, it is possible to measure the concentration of a particular absorber by observing its response to light at multiple wavelengths.

[0073] Therefore, the hyperspectral camera 800 can obtain more disease information than a general camera.

[0074] The optical coupler 500 can adjust the focus according to the depth of the cervix, which varies from person to person. In addition, one end 510 of the optical coupler 500 can be connected and fixed to the insertion part 100, and the other end 520 of the optical coupler 500 faces the connecting part 510 of the insertion part 100 and can be connected to the hyperspectral camera 800, so that the camera can be easily attached and detached using a quick coupler.

[0075] FIG. 7 shows a mobile colposcopy device 10 for early diagnosis of cervical cancer according to another embodiment of the present invention.

[0076] Elements performing the same functions as those in the previous figures are designated by the same reference numerals.

[0077] Referring to the drawings, the mobile colposcope device 10 for early diagnosis of cervical cancer further includes an expansion unit 600 in the insertion part 100 .

[0078] The expansion unit 600 is characterized by expanding the space inside the vagina when the insertion part 100 is inserted into the vagina, and is hollow so that one end of the insertion part 100 can be inserted therein, and is provided with a first expansion member 610 and a second expansion member 620.

[0079] The first extension member 610 includes a first body 611 extending a predetermined length in the front-rear direction, a first bracket 612 extending rearward from the rear half, and a first handle portion 613 extending downward from the first bracket 612 a predetermined length.

[0080] The second extension member 620 includes a second body 621 extending a predetermined length in the front-rear direction, a second bracket 622 at the rear end thereof that is rotatable relative to the first bracket 612, and a second handle portion 623 extending a predetermined length downward from the second bracket 622.

[0081] When an operator grips the first handle portion 613 and the second handle portion 623, the first extension member 610 and the second extension member 620 can be rotated.

[0082] A guide protrusion 614 is formed at the upper end of the first body 611, and a guide groove 615 is formed in the insertion part 100, extending a predetermined length along the insertion direction into the vagina, i.e., the front-to-back direction, so that the guide protrusion 614 is pulled into the guide groove 615.

[0083] In this embodiment, the guide protrusion 614 is formed on the upper surface of the first body 611 so as to protrude upward, but is not limited thereto, and may be formed on the lower surface of the second body 621.

[0084] Therefore, the first and second expansion members 610 and 620 are supported to be rotatable relative to each other in directions away from each other based on the center of the hollow.

[0085] Referring to FIG. 8, the operation of the expansion unit 600 will be described in detail as follows.

[0086] If the guide protrusion 614 moves along the guide groove 615 in the direction toward the viewing hole 110, the expansion unit 600 is inserted into the vagina before the insertion part 100, and when the insertion part 100 is inserted into the vagina, it is desirable that the guide protrusion 614 moves along the movement direction of the guide groove 615 in the direction toward the imaging part 200 to image the cervix.

[0087] 10 and 11 show the inlet 120 of a mobile colposcopy device 10 for early diagnosis of cervical cancer according to yet another embodiment of the present invention.

[0088] Elements performing the same function as in the previous figures are designated by the same reference numerals.

[0089] Referring to FIG. 10, the insertion part 100 further includes a communication part 125 and a jet pipe 123 .

[0090] The communication part 125 includes a main pipe 121 and a secondary pipe 122 .

[0091] The main pipe 121 is formed to be extended to a predetermined length so as to be connected to the inlet 120 .

[0092] The secondary pipe 122 extends from the main pipe 121 and is formed in the circumferential direction along the inner circumferential surface of the insertion part 100 .

[0093] The ejection pipe 123 extends from the auxiliary pipe 122 along the photographing path 130 toward the viewing hole 110, and at least one ejection port 124 is formed at the end of the viewing hole 110 so that the outside air introduced through the injection port 120 can be ejected or the test solution can be ejected toward the viewing hole 110.

[0094] Therefore, a test solution such as acetic acid can be injected into the injection port 120 and applied evenly to the cervix.

[0095] Referring to FIG. 11, a cross-sectional view of the viewing hole 110 having a plurality of the ejection pipes 123 is shown.

[0096] In this embodiment, four jet pipes 123 are used as an example, but the number and positions are not limited thereto.

[0097] The mobile colposcope device 10 for early diagnosis of cervical cancer of the present invention described above has the effect of enabling cervical cancer screening to be easily performed without environmental restrictions, not just in a hospital, by using the mobile colposcope, and making it easier for women to diagnose cervical cancer early.

[0098] The description of the embodiments presented is provided to enable any person skilled in the art to use or practice the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the scope of the present invention.
