Description

A detachable examination solution spray and tissue collection device attached to a mobile colposcopy

[0001] The present invention relates to a test solution spray and tissue collection device that can be attached to a mobile colposcopy, and more particularly, to a test solution spray and tissue collection device that can be attached to a mobile colposcopy used for tissue examination for early diagnosis of cervical cancer.

[0002] Cervical cancer is a common cancer among women worldwide, and although the incidence may vary by region, it is reported to have a significantly higher incidence in developing countries.

[0003] Cervical cancer is a disease that is effectively treated when detected early, but has a high mortality rate when detected in an advanced stage.

[0004] The 5-year survival rate for early-stage cervical cancer (stage 1 or lower) is over 90%, but for advanced cervical cancer, the 5-year survival rate drops sharply to less than 50%, so it can be said that the approach to prevention and treatment is greatly affected.

[0005] In particular, developing countries have high mortality rates from cervical cancer, and the lack of preventive and early diagnosis approaches contributes to this increased mortality rate.

[0006] Therefore, regular cervical screening will help prevent this cancer and provide early diagnosis and effective treatment.

[0007] According to the NCCN guidelines and the Korean Society of Gynecologic Oncology guidelines, colposcopy is a strongly recommended test due to its high diagnostic rate through systematic risk group classification and tissue examination.

[0008] The applicant has already developed a “mobile colposcopy device for early diagnosis of cervical cancer” (hereinafter referred to as “prior art”), as registered in Patent No. 10-2369740.

[0009] First, colposcopy can be broadly divided into three stages: 1) observation through magnification, 2) observation of white lesions after applying a 3% acetic acid solution, and 3) colposcopy-based tissue examination.

[0010] The existing colposcopy device has the problem of inconvenience and discomfort to the person being examined, as it requires removing the device from the vaginal canal of the person being examined after step 1), applying the 3% acetic acid solution in step 2), and then reinserting the colposcopy device back into the vagina.

[0011] In addition, in the 3) step of the existing colposcopy examination, there was a spatial limitation in performing a tissue examination while observing in real time with a colposcopy depending on the size of the existing colposcopy device.

[0012] In addition, when applying an acetic acid solution to the examination area, a cotton ball soaked in the acetic acid solution is placed in contact with the cervix to perform the examination. However, bleeding often occurs in cervical lesions, making it difficult to clearly identify white lesions. This leads to time and technical constraints in performing a biopsy of the exact area.

[0013] In addition, the above-mentioned prior art also has a form in which the injection port for injecting the test solution is connected to the photographing path, but it has limitations in that it is impossible to control the spray strength or spray amount of the solution and tissue examination cannot be performed.

[0014] Therefore, there is an urgent need to develop a device that can spray a test solution and collect tissue for tissue examination with a single device.

[0015] Prior art literature includes registered patent no. 10-2369740.

[0016] The present invention was invented to improve the above-mentioned problems, and provides a test solution spraying and tissue collection device that can be attached to a mobile colposcopy capable of spraying a test solution and collecting tissue for tissue examination with a single device.

[0017] In order to achieve the above object, the present invention provides a test solution spray and tissue collection device that is detachable from a mobile colposcopy, characterized by including: a main body detachable from an insertion part of a mobile colposcopy for photographing a cervix by inserting the mobile colposcopy while the vaginal opening of the subject is expanded with a vaginal dilator; a solution spraying means including a spray nozzle formed in the main body for atomizing and spraying a test solution onto tissue at the entrance side of the cervix; and a collection means including a tool hole formed in the main body for allowing the entry and exit of a tissue collector for collecting tissue at the entrance side of the cervix onto which the test solution has been sprayed.

[0018] Here, the main body is characterized in that it is formed in a cylindrical shape with both ends penetrating.

[0019] At this time, the main body is formed in a cylindrical shape with both ends penetrating, and the injection nozzles are characterized in that a plurality of them are arranged radially on the inner surface of the main body.

[0020] In addition, the main body is formed in a cylindrical shape with both ends penetrating, and the tool holes are arranged in multiple intervals on the inner surface of the main body.

[0021] In addition, the main body includes an outer cylinder having an inner surface facing the outer surface of the insertion portion and having a double-ended penetration, and an inner cylinder having an outer surface facing the inner surface of the outer cylinder and having a double-ended penetration that is caught and secured on a step formed at the outer surface of the tip of the insertion portion and the tip of the insertion portion, and a plurality of injection nozzles are arranged radially on the inner surface of the inner cylinder, and a plurality of tool holes are arranged, and the inner cylinder is characterized in that it can rotate forward and reversely with respect to the outer cylinder.

[0022] According to the present invention having the above configuration, the following effects can be achieved.

[0023] First, the present invention has the special advantage of being able to spray a test solution and collect tissue for tissue examination with a single device.

[0024] In particular, since colposcopy is basically a real-time visualization test, the present invention has the special advantage of enabling all stages of the three-step examination method mentioned in the background art to be examined at once in real time without removing and reinserting the camera.

[0025] The examination method using the device according to the present invention is highly versatile, as it can be easily implemented using a hysteroscopy tool commonly used in gynecology.

[0026] Above all, the device according to the present invention has the special advantage of being able to produce technically and medically accurate test results by minimizing bleeding and shortening the time required for confirming white lesions, since the test solution is applied to the tissue at the entrance of the cervix by atomizing the user through a spray nozzle rather than by direct contact with a cotton swab when applying a 3% acetic acid solution as the test solution, thereby minimizing bleeding and shortening the time required for confirming white lesions.

[0027] In other words, the device according to the present invention has a special advantage in that it can be manufactured to be compatible with various devices and thus complement and overcome the limitations of existing devices or prior art, since it is provided with a structure that can be detachably attached to the insertion part of the prior art registered by the present applicant.

[0028] Specifically, the device according to the present invention is a very useful invention in terms of compatibility and versatility by unifying the structure in which a drug injection tool and a tissue examination tool are inserted and connected, and making the size and volume lighter and more compact compared to existing tools.

[0029] In particular, since the transport and atomization spraying of the test solution through the transport channel of the solution spraying means according to the present invention can be used multiple times rather than once, it can be said to be economically efficient from the inspector's perspective, considering only the initial purchase cost.

[0030] Above all, the present invention has the unique advantage of being able to actively respond to the needs of various demanders because it does not require skill or high difficulty of the procedure.

[0068] Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings.

[0069] First, FIG. 1 is an exploded side view conceptual diagram illustrating the overall connection relationship of a detachable inspection solution spraying and tissue collection device attached to a mobile magnifying glass according to one embodiment of the present invention.

[0070] And, FIG. 2 is a cross-sectional conceptual diagram illustrating the internal structure of a test solution spraying and tissue collection device that can be attached to a mobile magnifying glass according to one embodiment of the present invention.

[0071] In addition, FIG. 3 is an exploded cross-sectional conceptual diagram illustrating a combined structure of a detachable inspection solution spraying and tissue collection device for a mobile magnifying glass according to one embodiment of the present invention.

[0072] In addition, Fig. 4 is a conceptual diagram of a cross-section taken along line iv-iv of Fig. 2.

[0073] As shown in FIGS. 1 to 4, the present invention may include a detachable main body (100) to an insertion part (500) of a mobile colposcopy device for photographing the cervix (not shown) by inserting the device while the entrance of the vagina (not shown) of the subject is expanded with a vaginal dilator (400).

[0074] Here, the present invention can form a solution spraying means (200) and a collection means (300) in the main body (100).

[0075] At this time, the solution spraying means (200) may include a spray nozzle (210) formed in the main body (100) to spray the test solution into the tissue at the entrance of the cervix in a misty form.

[0076] In addition, the collection means (300) may include a tool hole (310) formed in the main body (100) to allow the entry and exit of a tissue collector (320) that collects tissue from the entrance side of the cervix into which the test solution has been sprayed.

[0077] The present invention can be applied to the above-described embodiments, and of course, the following various embodiments can also be applied.

[0078] First, it can be confirmed that the main body (100) is formed in a cylindrical shape with both ends penetrating as shown in FIGS. 2 to 4, the injection nozzles (210) are arranged radially in multiple ways on the inner surface of the main body (100), and the tool holes (310) are arranged in multiple ways spaced apart on the inner surface of the main body (100).

[0079] Meanwhile, the main body (100), looking more specifically with reference to FIGS. 2 and 3 again, may include an outer tube (110) having an inner surface facing the outer surface of the insertion portion (500) and a double-ended, penetrating inner tube (120) having an outer surface facing the inner surface of the outer tube (110) and being caught and secured by a step portion (510) formed in a step on the outer surface of the front end of the insertion portion (500) and the front end of the insertion portion (500).

[0080] Here, a plurality of injection nozzles (210) are arranged radially on the inner surface of the inner cylinder (120), and a plurality of tool holes (310) are arranged, and the inner cylinder (120) can rotate forward and reversely with respect to the outer cylinder (110).

[0081] At this time, the inner tube (120) can rotate clockwise or counterclockwise relative to the outer tube (110) to provide convenience in determining the exact working position of the collection clamp (321) described later at the location where a white lesion is confirmed in the tissue of the cervical entrance to which the test solution is applied while checking the cervical entrance of the subject in real time with a camera.

[0082] In addition, the main body (100) may further include a catch ring rib (111) that protrudes in a ring shape along the inner surface of the distal end of the outer tube (110) to prevent the inner tube (120) from being separated from the distal end of the outer tube (110).

[0083] In addition, the main body (100) may further include a mounting flange (121) that protrudes in a ring shape along the outer surface of the front end of the inner tube (120) so that the front end of the inner tube (120) is mounted thereon, and a catch ring step (122) that is formed in a stepped shape along the outer surface of the distal end of the inner tube (120) so as to engage with the catch ring rib (111) so that the catch ring rib (111) is mounted thereon.

[0084] In addition, the main body (100) may further include a rotation lever (130) having at least one rotation guide slot (112) formed by a penetrating cut on the outer surface of the outer tube (110) and at least one protruding portion formed on the outer surface of the inner tube (120) and having a distal end exposed through the rotation guide slot (112).

[0085] The rotary lever (130) performs the role of guiding the forward and reverse rotation of the inner tube (120) relative to the outer tube (110) by reciprocating along the formation direction of the rotary guide slot (112) as shown in FIG. 4.

[0086] In addition, the main body (100) may further include a sawtooth-shaped anti-slip groove (131) formed on the distal end surface of the rotary lever (130) to prevent the finger of the examinee from coming into contact and slipping.

[0087] Accordingly, it can be confirmed that each of the terminal ends of the plurality of injection nozzles (210) are radially arranged along the terminal surface of the inner cylinder (120) where the catch ring step (122) is not formed.

[0088] In addition, it can be confirmed that the transport channel (220) through which the test solution is transported is connected to each of the tip ends of a plurality of injection nozzles (210) and formed on the inner surface of the inner cylinder (120) and extends to the tip end surface of the inner cylinder (120).

[0089] In addition, it can be confirmed that each of the distal ends of the plurality of tool holes (310) is radially arranged along the distal end surface of the inner tube (120) where the catch ring step (122) is not formed, and the tissue collection clamp (321) and guide wire (322) of the tissue collection device (320) are inserted from the distal end of one of the distal ends of the plurality of tool holes (310) that penetrate the distal end surface of the inner tube (120).

[0090] In addition, the solution spraying means (200) may further include a solution tank (230) that is connected to the tip of each of the transport channels (220) and a pipe (232) to receive the test solution, and a fluid motor (240) that is mounted on the pipe (232) connected to the solution tank (230) and transports the test solution toward the spray nozzle (210).

[0091] Accordingly, the examiner checks the cervical entrance of the examinee in real time through the camera (not shown) of the mobile terminal connected to the insertion unit (500) and sprays the examination solution into the tissue at the cervical entrance through multiple spray nozzles (210).

[0092] Thereafter, the examiner inserts the collection clamp (321) and the guide wire (322) through the tip of one of the plurality of tool holes (310) to access the tissue at the entrance of the cervix.

[0093] Continuing, the inspector can rotate the inner tube (120) clockwise or counterclockwise relative to the outer tube (110) by holding the rotation lever (130) and determine the appropriate sampling position of the sampling clamp (321) in real time through the display panel of a mobile terminal (not shown) connected to the camera.

[0094] As described above, it can be seen that the present invention has as its basic technical idea a method of providing a test solution spraying and tissue collection device that can be attached to a mobile colposcopy device capable of spraying a test solution and collecting tissue for tissue examination using a single device.

[0095] And, of course, many other modifications and applications are also possible for those with common knowledge in the industry within the scope of the basic technical idea of ​​the present invention.
