Description

Technical Field

[0001] The present invention relates to a mobile colposcope device for early diagnosis of cervical cancer. Specifically, the present invention relates to a mobile colposcope device for early diagnosis of cervical cancer having the following characteristics: the device can not only perform visual examination of cervical cancer in a hospital using a mobile colposcope, but also can perform the examination without restriction in a simple environment. Background Art

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

[0003] This type of cervical cancer, if detected in the early stage (precancerous stage), has better treatment and prognosis, but when it progresses to cancer, the survival rate drops to within 5 years, so women need to undergo cervical cancer screening every year for early detection.

[0004] Currently, cervical cancer screening methods include diagnostic methods such as cytology, colposcopy and tissue biopsy, as well as local destructive and surgical treatments, chemotherapy and radiotherapy. In addition, a method of self-diagnosis of cervical cancer using a kit for women's disease self-testing has recently been introduced.

[0005] The typical screening colposcopy method is to observe the cervix through a specially designed magnifying glass and visually check the cervix for various abnormal signs according to a series of diagnostic criteria. The suspicious area can be biopsied or treated. This method is easy to use in developed countries, but in developing countries such as Asia, South America, and Africa, where about 80% of cervical cancer occurs, cervical cancer is difficult to diagnose early due to tool problems.

[0064] Hereinafter, a mobile colposcopy device 10 for early diagnosis of cervical cancer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The present invention can be subjected to various modifications and can have various forms, so specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that this is not intended to limit the present invention to any particular disclosed form, and includes modifications, equivalents or substitutes included within the spirit or scope of the present invention.

[0068] Figure 1 to Figure 2 A first embodiment of a mobile colposcopy device 10 for early diagnosis of cervical cancer according to the present invention is shown.

[0069] 1 , a mobile colposcopy device 10 for early diagnosis of cervical cancer includes an insertion portion 100 , a photographing portion 200 , and a lighting portion 300 .

[0070] The insertion part 100 is inserted into the female vagina, and has a perspective hole 110 formed at one end in contact with the uterus, and a shooting path 130 communicating with the perspective hole 110 is disposed inside the insertion part 100 .

[0071] The photographing path 130 extends in the front-rear direction, and the rear portion of the insertion portion 100 is opened to communicate with the photographing portion 200 .

[0072] This makes it easy to insert the insertion unit 100 into the vagina. In addition, at this time, the insertion unit 100 is formed into a tapered shape with an inner diameter decreasing from the imaging unit 200 toward the perspective hole 110, so that the inner diameter of the imaging path 130 is reduced, so that the light irradiated from the lighting unit 300 is not directly irradiated, but becomes indirect illumination through scattered light, thereby reducing reflection on the surface of the cervical tissue.

[0073] The perspective hole 110 is formed to be inclined at a predetermined angle based on the longitudinal center line of the photographing path 130. Preferably, the examiner examines the cervix by bringing the inclined perspective hole 110 into contact with the cervix.

[0074] The perspective hole 110 inclined at a predetermined angle ensures the photographing path 130 by pushing away the cervical tissue 900 that obstructs the photographing path 130 with the inclined portion of the perspective hole 110 when examining a cervix that is different for each person due to individual anatomical differences.

[0075] In addition, the insertion portion 100 has an injection port 120 formed on an outer peripheral surface thereof to communicate with the imaging path 130 .

[0076] The air circulates to the outside on the photographing path 130 through the injection port 120, thereby preventing fogging in the photographing unit 200. If fogging occurs in the photographing unit 200, the air flowing into the injection port 120 from the outside is discharged through the perspective hole 110 inclined at a predetermined angle, so that the air can circulate.

[0077] The position and size of the injection port 120 are not limited.

[0078] The photographing unit 200 is provided with a smartphone 700 with a photographing camera 710, and the photographing unit 200 is installed at the rear end of the insertion unit 100 to install the smartphone 700 with the photographing camera 710. The photographing unit 200 has an entrance space 210 formed at the rear thereof for introducing the smartphone 700. The entrance space 210 is formed to correspond to the cross-sectional area of ​​the smartphone 700 in order to press the smartphone 700 in.

[0079] The entrance space 210 is formed with an installation opening 211, which can be used to install a shooting lens of a shooting camera 710 equipped on the smartphone 700 at a position opposite to the perspective hole 110 relative to the rear of the shooting unit (200).

[0080] The mounting port 211 is formed at a position opposite to the perspective hole 110 and is formed with an area corresponding to the lens of the photographing camera 710 , so that the lens of the photographing camera 710 of the smartphone 700 can be inserted therein.

[0081] At this time, the photographing unit 200 supports the smartphone 700 so that the photographing camera 710 faces the perspective hole 110 in order to allow the photographing camera 710 to photograph the cervix through the perspective hole 110 .

[0082] Although not shown in the drawings, the photographing unit 200 includes a first adjustment member, a second adjustment member, and a spring member.

[0083] When the smartphone 700 is introduced into the entrance space 210 , the smartphone 700 is mounted on the first adjustment member, and the second adjustment member can fix the smartphone 700 mounted on the first adjustment member by adjusting the length and width through the spring member.

[0084] The lighting unit 300 includes a light source 310 and a light guide 320 .

[0085] The light source 310 is disposed under the inserting portion 100 to irradiate light onto the photographing path 130 .

[0086] The light guide 320 is installed inside the insertion portion 100 to guide the illumination generated from the light source 310 in the direction of the perspective hole 110 .

[0087] The light guide 320 is installed on the inner wall surface of the insertion portion 100 opposite to the light source 310 and a reflector capable of reflecting the light generated by the light source 310 to the perspective hole 110 is applied.

[0088] On the other hand, although not shown in the figure, one end of the light guide 320 is arranged at the light source 310, and the other end is arranged inside the insertion part 100 and is arranged opposite to the perspective hole 110, so that an optical fiber that generates the optical waveguide generated by the light source 310 and transmits it to the perspective hole 110 can be applied.

[0089] At this time, preferably, a plurality of optical fibers are arranged, and one end of each of the optical fibers is bundled and connected to the light source 310. The other ends of the optical fibers are dispersed and introduced into the insertion portion 100 to be spaced apart from each other and arranged to face the perspective hole 110.

[0090] When the light emitted from the light source 310 is input to one end of the optical fiber, a second optical coupler such as a lens may be used. The light input to one end of the optical fiber is transmitted along the optical fiber to the other end, so that the light can be emitted from the perspective hole 110 .

[0091] The insertion part 100 allows the perspective hole 110 to completely and closely contact the surface of the cervix to prevent external light such as fluorescent light from flowing in. That is, only the predetermined light of the illumination part 300 is irradiated to the cervix, so that the illumination condition irradiated to the cervix is ​​constant.

[0092] The effect of obtaining images while always maintaining the same shooting conditions like this is that distortion can be reduced when analyzing disease staging using artificial intelligence later.

[0093] In the first embodiment, the inserting part 100 , the photographing part 200 , and the illuminating part 300 are manufactured by 3D printing, so they can be manufactured and used more easily.

[0094] Figure 3 to Figure 4 A mobile colposcopy device 10 for early diagnosis of cervical cancer according to a second embodiment is shown.

[0095] Elements having the same functions as in the above-described drawings are denoted by the same reference numerals.

[0096] Referring to the accompanying drawings, the photographing unit 200 is installed at the rear end of the insertion unit 100 opposite to the perspective hole 110 and an endoscopic camera opposite to the perspective hole 110 is applied, and the mobile colposcopy device 10 for early diagnosis of cervical cancer is also provided with an optical unit 400, which is installed on the photographing path 130.

[0097] Fig. 9 The principle of the polarization system of the optical part 400 according to the second embodiment is shown.

[0098] The optical portion 400 blocks the light reflected from the cervical tissue surface 910 and flowing into the perspective hole 110 , and allows only the light that passes through the cervical tissue surface 910 and is reflected from the cervical tissue interior 920 to the perspective hole 110 to pass therethrough.

[0099] The optical part 400 includes a linear polarizer 410 and a quarter wave plate (1 / 4λ retarder) 420 .

[0100] The linear polarizer 410 is first installed on the photographing path 130 and forms parallel polarized light 430 of the light output from the light source 310 .

[0101] The quarter wave plate 420 is installed behind the linear polarizing plate 410 based on the output direction of light on the photographing path, and the light passing through the linear polarizing plate 410 is formed into left-handed circularly polarized light 431 .

[0102] If the unpolarized light emitted from the light source 310 passes through the linear polarizer 410 , parallel polarized light 430 is generated, and the light generating the parallel polarized light 430 passes through the quarter wave plate 420 , and at the same time, left-handed circularly polarized light 431 is generated.

[0103] The light returning after regular reflection from the cervical tissue surface 910 generates right-handed circularly polarized light 433 , and if the right-handed circularly polarized light 433 passes through the quarter-wave plate 420 , vertically polarized light 432 is generated, but the light does not reach the photographing unit 200 because it does not pass through the linear polarizing plate 410 .

[0104] Conversely, similarly, when the light passing through the linear polarizer 410 and the quarter wave plate 420 is reflected inside the cervical tissue 920, the reflected light includes information about the inside of the cervical tissue 920 and first passes through the quarter wave plate 420, and after passing through the linear polarizer 410, becomes parallel polarized light 430 and reaches the shooting unit 200.

[0105] As a result, light reflected from the surface 910 of the cervical tissue does not enter the photographing unit 200, and only light reflected from the interior 920 of the remaining cervical tissue passes through, thereby removing surface reflections that interfere with data analysis and diagnosis.

[0106] on the other hand, Figures 5 and 6 A mobile colposcopy device 10 for early diagnosis of cervical cancer according to a third embodiment is shown.

[0107] Elements having the same functions as in the above-described drawings are denoted by the same reference numerals.

[0108] Referring to the accompanying drawings, the shooting unit 200 is characterized in that it includes: a hyperspectral camera 800, which is arranged at the rear end of the insertion unit 100 opposite to the perspective hole 110 and opposite to the perspective hole 110; and an optical coupler 500, which is arranged between the hyperspectral camera 800 and the insertion unit 100.

[0109] The optical coupler 500 is a connecting component including a lens, which controls the focal length of the hyperspectral camera 800 so that the image of the cervix is ​​accurately focused on the image sensor of the hyperspectral camera 800 .

[0110] The hyperspectral camera 800 acquires multiple photos with the same field of view for different wavelengths of light. When examining the cervix, if acetic acid is applied to the cervix, the abnormal area will turn white. This is because applying acetic acid makes a particular wavelength of light reflect less, while a certain wavelength of light reflects more.

[0111] Objects that appear blue absorb light other than blue and reflect blue, so our eyes or cameras recognize it as blue. If this color is changed to red through some operation, it means that the degree of reflection and absorption of each wavelength has changed. Existing cameras only have three RGB pixels, so they cannot accurately analyze the reaction of the cervix to various wavelengths of light.

[0112] However, for example, if there is a hyperspectral camera 800 that can take images at 16 wavelengths, color changes can be analyzed more accurately and more information can be obtained. On the other hand, the concentrations of various light absorbers in the cervix can also be indirectly measured by using the images of each wavelength of the hyperspectral camera 800. That is, if there are many light absorbers that can absorb light of a specific wavelength well, the amount of light of that wavelength that is reflected and returned to the camera will decrease (Beer-Lambert Law). The absorption spectra of light absorbers mainly distributed in the human body are well known to medical personnel, so by observing the reactions of light of multiple wavelengths, it is possible to measure which light absorbers are present and what their concentrations are.

[0113] Accordingly, if the hyperspectral camera 800 is used, more disease information can be obtained than that of an ordinary camera.

[0114] The optical coupler 500 can adjust the focus according to the depth of the cervix formed differently for each person. In addition, one end 510 of the optical coupler can be connected and fixed to the insertion part 100, and the other end 520 of the optical coupler can be opposite to the connection part of the insertion part 100 to connect to the hyperspectral camera 800, and the camera can be easily installed and removed using a quick coupler.

[0117] Referring to the drawings, the mobile colposcopy device 10 for early diagnosis of cervical cancer further includes an expansion unit 600 in the insertion portion 100 , and further includes an expansion unit 600 disposed in the insertion portion 100 .

[0118] The expansion unit 600 is characterized in that the insertion part 100 expands the vaginal space when inserted into the vagina and forms a hollow so that one end of the insertion part 100 can be inserted. In addition, the expansion unit 600 includes a first expansion member 610 and a second expansion member 620.

[0123] In the present embodiment, the guide protrusion 614 is formed to protrude upward from the upper surface of the first body 611 , but is not limited thereto and may also be formed on the lower surface of the second body 621 .

[0124] The first expansion member 610 and the second expansion member 620 support each other rotatably in directions becoming distant from each other based on the center of the hollow.
