Abstract

Disclosed is a mobile colposcopy device for early diagnosis of cervical cancer, which includes an insertion unit which is inserted into the vagina of a woman, has a penetrating hole formed in one end coming into contact with the uterus, and is provided with a capturing path communicating with the penetrating hole, a capturing unit which is provided in the insertion unit so as to capture the cervix through the capturing path, and a lighting unit which is provided on the capturing path of the insertion unit and irradiates a lighting to the cervix through the penetrating hole. According to the present disclosure, the mobile colposcopy device for early diagnosis of cervical cancer can be simply and easily used so as to perform cervical cancer screening using a mobile colposcopy without environmental constraints including hospitals and allows women to early diagnose cervical cancer.

Claims (22)

1. A mobile colposcopy device for early diagnosis of cervical cancer comprising:

an insertion unit configured to be inserted into a vagina of a woman, having a truncated cone shape, and comprising a first end having a penetrating hole configured to come into contact with a uterus, and a capturing path configured to communicate with the penetrating hole;

a capturing unit configured to capture an image of a cervix through the capturing path of the insertion unit; and

a lighting unit positioned between the insertion unit and the capturing unit, and configured to irradiate light toward the cervix through the penetrating hole of the insertion unit,

wherein the insertion unit comprises:

an inlet positioned an upper surface of the insertion unit, and configured to circulate air in the capturing path to an outside the mobile colposcopy device, and inject a test solution to the cervix;

an auxiliary pipe having a ring shape positioned along an inner circumferential surface of the insertion unit;

a main pipe connecting the inlet and the auxiliary pipe; and

a plurality of ejection pipes, each of which is extended toward the penetrating hole along the capturing path from the auxiliary pipe, and has an outlet configured to eject, through the penetrating hole, external air introduced through the inlet, or the test solution introduced through the inlet.

2. The mobile colposcopy device of claim 1 , wherein the lighting unit includes a light source configured to irradiate the light on the capturing path; and a light guide which induces the light generated in the light source in a direction of the penetrating hole.

3. The mobile colposcopy device of claim 1 , further comprising:

an optical unit positioned on the capturing path and configured to block reflection light which is reflected on a surface of a cervical tissue to be introduced to the penetrating hole, and transmit only a lighting which is reflected to the penetrating hole from an inside of the cervical tissue by passing through the surface of the cervical tissue.

4. The mobile colposcopy device of claim 1 , wherein the capturing unit is configured to hold a smartphone having a capturing camera, and support the smartphone so that the capturing camera faces the penetrating hole and captures the cervix through the penetrating hole.

5. The mobile colposcopy device of claim 4 , wherein an insertion space is provided at a second end of the insertion unit and formed so that the smartphone is inserted, but formed with a setting port in which a capturing lens of the capturing camera is set at a position facing the penetrating hole.

6. The mobile colposcopy device of claim 3 , wherein the capturing unit is any one of an endoscope camera and a hyperspectral camera.

7. The mobile colposcopy device of claim 1 , wherein the penetrating hole is inclined at a predetermined angle based on a longitudinal center line of the capturing path.

8. The mobile colposcopy device of claim 1 , further comprising:

an extension unit which extends a space in the vagina when the insertion unit is inserted into the vagina.

9. The mobile colposcopy device of claim 8 , wherein the extension unit has a hollow so that an end of the insertion unit may be inserted, but includes a first extension member and a second extension member which are supported to each other to be rotatable with each other so that it may be far from a center of the hollow; and a plurality of handles which are formed in the extension unit and configured to be held by an operator, to rotate the first and second extension members.

10. The mobile colposcopy device of claim 9 , wherein the insertion unit has a guide groove extended in a predetermined length along an insertion direction to the vagina, and the extension unit has a guide protrusion formed on any one of the first extension member and the second extension member so as to be inserted to the guide groove.

11. The mobile colposcopy device of claim 1 , wherein the insertion unit has an inner diameter which is tapered to be closer to the penetrating hole so that scattering light output from the lighting unit and scattered by an inner wall surface is incident to a cervical tissue.

12. The mobile colposcopy device of claim 4 , wherein the optical unit consists of a linear polarizer (LP) which is provided on the capturing path and forms a parallel polarization (P-polarization) of light output from the lighting unit and a 1/4λ retarder (QWP) which is provided behind the linear polarizer based on an output direction of the light on the capturing path to form light passing through the linear polarizer to a left circular polarization.
