Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a non-invasive vaginal examination and treatment device. Background Technology

[0002] Vaginal examination is a core means of assessing the health of a woman's reproductive system in gynecological clinical practice. Through visual inspection, palpation, and auxiliary testing techniques, it comprehensively screens for abnormal lesions in the vagina, cervix, and adjacent tissues. Its core value lies in the early detection of potential problems such as inflammation, infection, structural malformation, or tumors. For example, secretion testing can identify bacterial vaginosis or Candida infection.

[0003] In clinical practice, women who have never had sexual intercourse and women with reproductive tract abnormalities (such as a perforated hymen) are a group requiring special evaluation. Examinations must adhere to the principle of minimal invasiveness, prioritizing non-invasive methods such as visual inspection of the vulva and swab sampling of secretions. However, when these groups present with persistent abnormal secretions, vaginal bleeding, or suspected reproductive tract abnormalities, further diagnostic clarification is necessary. This typically requires procedures performed under anesthesia in an operating room using instruments such as a Killian nasal endoscope, hysteroscope, or cystoscope with a light source. Outpatient clinics cannot directly examine the vagina, cannot directly visualize the vagina and cervix, cannot visually identify lesions, and cannot perform simple procedures such as foreign body removal. This increases the anesthesia-related risks and medical costs for patients, and also wastes human resources. Therefore, this application proposes a non-invasive vaginal examination and processing device to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a non-invasive vaginal examination and treatment device. This device enters the vagina through a visual acquisition tube from the vaginal opening to achieve real-time image acquisition of the vaginal interior.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 The non-invasive vaginal examination and treatment device in this embodiment includes a handheld housing 1 and a visual acquisition tube 3 extending through one end of the handheld housing 1. The working end of the visual acquisition tube 3 is provided with an end mounting base 7 integrally formed therewith. An image acquisition camera 5 for image acquisition is provided along the center line inside the end mounting base 7. An LED ring light 6 fixed inside the end mounting base 7 is provided on the outer periphery of the image acquisition camera 5.

[0035] The image capture camera 5 captures images, while the LED ring light 6 provides supplementary lighting. In use, the user holds the handheld casing 1, inserts the visual acquisition tube 3 into the vagina through the vaginal opening, and turns on the LED ring light 6 and the image capture camera 5 to capture images inside the vagina.

[0036] It should be noted that the diameter of the visual acquisition tube 3 is 0.3-0.5 cm. Both the LED ring light 6 and the image acquisition camera 5 are existing technologies. They can be purchased through normal market procurement channels to meet the size requirements of the visual acquisition tube 3 and have good imaging effects. The smaller size design can better meet the principle of minimizing intrusion.

[0037] It also includes a control compartment 2, a battery 21, a flushing sleeve 4, and a flushing mechanism. The control compartment 2 is fixed inside the handheld housing 1 and connected to the vision acquisition tube 3. The battery 21 is fixedly installed inside the tail end of the handheld housing 1 to power the entire device. The flushing sleeve 4 is fixedly sleeved on the outer periphery of the vision acquisition tube 3 and extends through the handheld housing 1 together with the vision acquisition tube 3. A sandwich is formed between the flushing sleeve 4 and the vision acquisition tube 3 to allow the flow of the medium. The flushing mechanism is located inside the handheld housing 1 and is used to perform flushing in conjunction with the sandwich formed between the flushing sleeve 4 and the vision acquisition tube 3.

[0038] The control compartment 2 serves as the control center of the entire device, housing a control circuit board. This circuit board has interfaces for connecting different hardware components, extending from the control compartment 2 for easy external hardware connection. Both the LED ring light 6 and the image capture camera 5 are connected to the control circuit board within the control compartment 2 for power supply and video data transmission. The connection lines run through the internal visual acquisition tube 3. Furthermore, the control circuit board also includes a signal transmission module that can connect to a mobile phone and transmit the captured video data to the phone for real-time viewing. It should be noted that the aforementioned image capture and transmission to a mobile phone for real-time viewing is a well-known technology in the prior art, and the relevant hardware can be purchased through normal market channels; therefore, it will not be elaborated upon further in this article.

[0039] The battery 21 is connected to the interface on the control circuit board via a circuit to provide power to the entire device.

[0040] In clinical practice, when there is inflammation in the vagina, it is often necessary to use antibacterial rinsing solution to rinse the vagina as an adjunct treatment. The rinsing sleeve 4 and the rinsing mechanism are designed to achieve this function. Specifically, the rinsing mechanism includes a cleaning fluid tank 11, which is detachably installed below the handheld housing 1. A peristaltic pump 17 is fixed inside the handheld housing 1. A suction tube 15 is provided inside the handheld housing 1, with one end inserted into the cleaning fluid tank 11. The inlet end of the peristaltic pump 17 is connected to a first flow tube 16 located inside the handheld housing 1 and allowing media to flow between it and the suction tube 15. A one-way valve 13 is fixed on the suction tube 15. The outlet end of the peristaltic pump 17 is connected to a second flow tube 18 located inside the handheld housing 1. A straight-through pressure sensor 19 is fixed to the other end of the second flow tube 18. A third flow tube 20 connected to the rinsing sleeve 4 is fixed to the other end of the straight-through pressure sensor 19.

[0041] It should be noted that the cleaning fluid tank 11 is installed on the handheld housing 1 by means of threaded installation. A connecting ring with a threaded outer peripheral wall is fixed at the bottom of the handheld housing 1. The cleaning fluid tank 11 is a capless design. The opening of the tank has a threaded groove that connects with the threaded outer peripheral wall of the connecting ring. A third sealing ring is also fixed on the inner wall of the opening. A third rubber sealing ring that can abut against the connecting ring is fixed on the upper surface of the third sealing ring. When the cleaning fluid tank 11 is screwed onto the connecting ring, the third rubber sealing ring abuts against the connecting ring to achieve a seal. In addition, when the liquid extraction tube 15 passes through the handheld housing 1 and is inserted into the cleaning fluid tank 11, the penetration point between the liquid extraction tube 15 and the handheld housing 1 is also sealed.

[0042] During operation, by activating the peristaltic pump 17, the cleaning fluid in the cleaning fluid tank 11 can be drawn by the suction tube 15. The cleaning fluid passes through the first flow tube 16, the second flow tube 18, and the third flow tube 20 in sequence before entering the flushing sleeve 4. Then, it flows into the interlayer formed between the flushing sleeve 4 and the visual acquisition tube 3, and finally sprays out from the front end of the visual acquisition tube 3 to achieve vaginal flushing. During this process, the direct-flow pressure sensor 19 is used to monitor the flow pressure of the cleaning fluid to avoid excessive or insufficient pressure. Both the peristaltic pump 17 and the direct-flow pressure sensor 19 are connected to the interface on the control circuit board through wiring to achieve linkage control between the peristaltic pump 17 and the direct-flow pressure sensor 19. In addition, the one-way valve 13 is set to prevent the backflow of the cleaning fluid.

[0043] Women who are asexual or have reproductive tract abnormalities are a group that requires special evaluation. In clinical practice, outpatient clinics often encounter various complex situations during vaginal examinations. In addition to direct visualization of the vagina and cervix, some simple procedures are also required, such as foreign body removal, secretion extraction, and biopsy tissue retrieval. Therefore, in this application, the working end of the visual acquisition tube 3 is also equipped with one of the following components: secretion extraction component, tissue biopsy extraction component, foreign body retrieval component, and negative pressure suction component. The appropriate component can be selected for use in different situations.

[0044] The secretion extraction assembly includes a first connecting ring 2801 threadedly connected to an end mounting base 7. A curved connecting plate 2802 extends from the lower right edge of the first connecting ring 2801. A fixing ring 2803 is connected to the right side of the curved connecting plate 2802, and a cotton swab 2804 is inserted into the fixing ring 2803. The outer peripheral wall of the end mounting base 7 has a threaded groove, and the inner peripheral wall of the first connecting ring 2801 has threads that connect with the threaded groove. The first connecting ring 2801, the curved connecting plate 2802, and the fixing ring 2803 are integrally formed. The inner and outer diameters of the fixing ring 2803 are both smaller than the inner and outer diameters of the first connecting ring 2801. After the cotton swab 2804 is inserted into the fixing ring 2803, the two are seamlessly fitted.

[0045] In use, the first connecting ring 2801 is screwed onto the end mounting base 7, and then the cotton swab 2804 is inserted into the fixing ring 2803. The visual acquisition tube 3, together with the secretion extraction component, enters the vagina from the patient's vaginal opening. With the supplementary lighting of the image acquisition camera 5 and the LED ring light 6, the secretions inside the vagina are collected. It should be noted that after the cotton swab 2804 is inserted into the fixing ring 2803, the two will not fall off during the normal secretion extraction process. After use, the user can forcefully pull out the cotton swab 2804 for storage for subsequent examinations. The first connecting ring 2801, the curved connecting plate 2802, and the fixing ring 2803 are integrally formed and made of stainless steel. They can be disinfected and reused.

[0046] In this application, the tissue biopsy extraction component and the foreign body grasping component need to achieve certain movements. To control the movement of the related movements, the outer side of the flushing sleeve 4 is movably fitted with a movable sleeve 32 that passes through the handheld housing 1 together with it. The handheld housing 1 has a rotatable threaded ring 9 that is threadedly connected to the outer wall of the movable sleeve 32. The outer peripheral wall of the threaded ring 9 has a limiting groove. The inner wall of the handheld housing 1 is fixed with a limiting ring 24 that matches the limiting groove. The outer peripheral wall of the threaded ring 9 is fixed with a driven bevel ring 22. The lower front end of the handheld housing 1 is fixed with an adjusting motor 8. The output shaft of the adjusting motor 8 is fixed with an active bevel ring 23 located inside the handheld housing 1 and meshing with the driven bevel ring 22. The outer wall of the movable sleeve 32 is fixed with multiple limiting sliders 26. The inner wall of the handheld housing 1 has multiple limiting grooves 25 that are slidably connected to the multiple limiting sliders 26 respectively. The front end of the movable sleeve 32 is threadedly fixed with an arc-shaped protective cover 27 with an opening on the right side.

[0047] The handheld housing 1 employs a limiting design to ensure that the positions of the flushing sleeve 4 and the vision acquisition tube 3 are restricted after installation within the housing 1, preventing movement. The movable sleeve 32 is fitted onto the flushing sleeve 4 and can slide linearly on it. The front end of the handheld housing 1 has an opening for the movable sleeve 32 to pass through and move linearly. The inner circumferential wall of the threaded ring 9 is threaded, and the outer circumferential wall of the movable sleeve 32 has a threaded groove that connects with the inner thread of the threaded ring 9. The regulating motor 8 is connected to the interface on the control circuit board via wiring, enabling power supply and control of the regulating motor 8. When the regulating motor 8 starts, the engagement of the active bevel gear ring 23 and the driven bevel gear ring 22 rotates the threaded ring 9, thereby driving the movable sleeve 32. The movable sleeve 32 moves left and right. The outer peripheral wall of the front end of the movable sleeve 32 has a threaded groove. The inner peripheral wall of the arc-shaped protective cover 27 is threaded and can be threaded to connect with the threaded groove of the outer peripheral wall of the front end of the movable sleeve 32. The arc-shaped protective cover 27 is used to control the operation of the tissue biopsy extraction component and the foreign body grasping component. At the same time, the arc-shaped protective cover 27 can also move forward with the movement of the movable sleeve 32, so as to take in the secretion extraction component. Because the front end of the arc-shaped protective cover 27 is arc-shaped, after the secretion extraction component is taken in the arc-shaped protective cover 27, when it enters the vagina from the vaginal opening, it meets the principle of minimizing invasion and reducing patient discomfort. After entering the vagina, the position of the movable sleeve 32 can be adjusted to move the arc-shaped protective cover 27 so that the secretion extraction component is exposed.

[0048] The tissue biopsy extraction assembly includes a second connecting ring 2901 threadedly connected to an end mounting base 7. A first arc-shaped connecting plate 2902 extends outward from both the upper and lower right edges of the second connecting ring 2901. Each of the two first arc-shaped connecting plates 2902 has a first clearance hole 2903. A first rotating shaft 2904 is fixed to each of the two first arc-shaped connecting plates 2902. A first hinge frame 2905, passing through the first clearance hole 2903, is sleeved on the first rotating shaft 2904. A component located on the first arc-shaped connecting plate 2902 is fixed to the first hinge frame 2905. The outer side of the plate 2902 has a flip plate 2908. The front ends of the two flip plates 2908 are integrally formed with biopsy tissue clamping plates 2907 that can interlock with each other. The left side of the two flip plates 2908 is integrally formed with a first double-sided extrusion block 2906 that can be placed in the first clearance hole 2903. The left and right sides of the first double-sided extrusion block 2906 facing the arc-shaped protective cover 27 are inclined downward until they are flush with the flip plate 2908. The two sides of the flip plate 2908 are respectively attached to the arc-shaped protective cover 27 and the first arc-shaped connecting plate 2902.

[0049] The foreign object gripping assembly includes a third connecting ring 3001 threadedly connected to an end mounting base 7. At least three equidistantly distributed second arc-shaped connecting plates 3007 extend outward from the right edge of the third connecting ring 3001. Each second arc-shaped connecting plate 3007 has a second clearance hole 3002. A second rotating shaft 3003 is fixed to the second arc-shaped connecting plate 3007. A second hinge frame 3004, passing through the second clearance hole 3002, is sleeved on the second rotating shaft 3003. A component located on the second arc-shaped connecting plate 3007 is fixed to the second hinge frame 3004. The foreign object gripping plate 3006 on the outside of 007 has multiple foreign object gripping plates 3006 whose front ends are bent toward the central axis of the vision acquisition tube 3. The left side of each of the multiple foreign object gripping plates 3006 has an integrally formed second double-sided extrusion block 3005 that can be placed in the second clearance hole 3002. The left and right sides of the second double-sided extrusion block 3005 facing the arc-shaped protective cover 27 are inclined downwards until they are flush with the foreign object gripping plate 3006. The two sides of the foreign object gripping plate 3006 are respectively attached to the arc-shaped protective cover 27 and the second arc-shaped connecting plate 3007.

[0050] The inner peripheral walls of both the second connecting ring 2901 and the third connecting ring 3001 are threaded to the threaded grooves on the outer peripheral wall of the end mounting seat 7. By screwing the second connecting ring 2901 or the third connecting ring 3001 onto the end mounting seat 7, the tissue biopsy extraction assembly or foreign body retrieval assembly is installed. The working principles of the tissue biopsy extraction assembly and the foreign body retrieval assembly are similar. During operation, the arc-shaped protective cover 27 moves left and right to compress the first double-sided compression block 2906 or the second double-sided compression block 3005, causing the flipping plate 2908 or the foreign body retrieval plate 3006 to flip. Conversely, the two biopsy tissue retrieval plates 2907 abut against each other, thus protecting multiple foreign bodies. The relative movement of the biopsy tissue retrieval plate 3006 enables the retrieval of biopsy tissue or foreign objects. In addition, it should be noted that during the process of the tissue biopsy extraction component and the foreign object retrieval component entering the vagina, the entry end of the biopsy tissue retrieval plate 2907 in the tissue biopsy extraction component adopts an arc-shaped design to minimize discomfort during invasion. At the same time, during the installation of the tissue biopsy extraction component and the foreign object retrieval component, the flip plate 2908 or the foreign object retrieval plate 3006 can be manually flipped until the inclined surface of the first double-sided compression block 2906 or the second double-sided compression block 3005 is horizontal. At this time, the second connecting ring 2901 or the third connecting ring 3001 can be inserted into the arc-shaped anti-slip cover and screwed onto the end mounting base 7.

[0051] In actual use, small foreign objects, such as hair, may be present in the patient's vagina. In such cases, the aforementioned foreign object retrieval components are often difficult to remove. Therefore, this application also includes a negative pressure suction mechanism to achieve negative pressure suction. The negative pressure suction mechanism includes a waste liquid chamber 10, which is detachably installed below the handheld housing 1. The handheld housing 1 has a suction tube 15 with one end inserted into the waste liquid chamber 10. A one-way valve 13 is fixed on the suction tube 15. The handheld housing 1 also has an electric three-way valve 12. The three ports of the electric three-way valve 12 are respectively connected to the suction tube 15, the drain tube 14, and the first flow tube 16. The peristaltic pump 17 is a bidirectional peristaltic pump.

[0052] The connection and installation of the waste liquid tank 10 and the handheld housing 1 are similar to those of the cleaning liquid tank 11, and will not be described in detail here. The electric three-way valve 12 is connected to the interface on the control circuit board via a circuit to control the electric three-way valve 12. The one-way valve 13 is provided to prevent the waste liquid in the waste liquid tank 10 from flowing back. During operation, by starting the bidirectional peristaltic pump, the bidirectional peristaltic pump moves in reverse, and at the same time, the electric three-way valve 12 is controlled, so that the medium flowing out of the first flow pipe 16 is discharged through the drain pipe 14, and the suction pipe 15 is closed.

[0053] The negative pressure suction assembly cooperates with the negative pressure suction mechanism. The negative pressure suction assembly includes an annular sealing cap that is threadedly connected to the flushing sleeve 4. The annular sealing cap has an outer annular wall 3101 and an inner annular wall 3108. The outer annular wall 3101 is threadedly connected to the flushing sleeve 4. A first sealing ring 3102 is fixed to the inner circumferential wall of the outer annular wall 3101 to form a seal with the flushing sleeve 4. A visual acquisition tube 3 is fixed to the inner circumferential wall of the inner annular wall 3108. A second sealing ring 3103 is formed between them to form a seal. After the annular sealing cover is threadedly connected to the flushing sleeve 4, a flow guiding space 3104 communicating with the interlayer is formed. A hollow connecting plate 3105 communicating with the flow guiding space 3104 is fixed on the right side of the annular sealing cover. A negative pressure adsorption chamber 3106 with an open top is fixed above the hollow connecting plate 3105. Multiple suction holes 3107 communicating with the hollow interior of the hollow connecting plate 3105 are opened on the bottom wall of the negative pressure adsorption chamber 3106.

[0054] The flushing sleeve 4 has a threaded groove on its outer peripheral wall, and the inner peripheral wall of the sealing cap 3101 has a thread that connects to the threaded groove. One side of the first sealing ring 3102 and the second sealing ring 3103 are each fixed with a rubber sealing ring that abuts against the flushing sleeve 4 and the visual acquisition tube 3, respectively. Multiple suction holes 3107 are evenly distributed on the negative pressure adsorption chamber 3106. The annular sealing cap, the hollow connecting plate 3105, and the negative pressure adsorption chamber 3106 are integrally formed. In use, the opening side of the negative pressure adsorption chamber 3106 can be placed against the foreign object, and the bidirectional peristaltic pump can be started. At this time, the negative pressure adsorption chamber 3106 generates negative pressure, adsorbing the foreign object. The foreign object will not enter the interlayer through the suction holes 3107. Then, the negative pressure adsorption chamber 3106, along with the foreign object, is pulled out of the vagina, thus removing the foreign object.

[0055] In addition, it should be noted that in this application, the tissue biopsy extraction component, the foreign body grasping component, and the negative pressure suction component are all made of stainless steel. After use, they can be disinfected and reused.
