Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a visual cleaner. Background Technology

[0002] In clinical practice in gynecology and proctology, cleaning of cavities such as the vagina and rectum is a common treatment and nursing procedure. Traditional cleaning devices typically employ rigid or semi-rigid tubular structures, entering the cavity directly through insertion. For patients with unhealed wounds, this insertion method directly contacts the wound, intensifying pain and potentially worsening the injury. Traditional cleaning devices are often operated blindly, preventing doctors from observing the internal condition of the cavity in real time. Consequently, it is difficult to avoid wounds during the procedure, increasing operational risks. Although some existing technologies attempt to incorporate cameras, they lack coordinated design with the mechanical structure, making it impossible to achieve both visualization and avoidance of specific areas. Summary of the Invention

[0003] This invention discloses a visual cleaning device that, through the collaborative design of its components, enables flexible expansion and introduction of cavities, precise visual operation, and selective wound avoidance, thereby preventing mechanical damage to the human body and improving patient comfort and operational safety.

[0004] Accordingly, the present invention discloses a visual cleaner, including a cleaner housing, a cleaning assembly, a camera assembly, and a flexible expansion assembly;

[0005] The cleaner housing has an extension end located on the axial front side and an operating end located on the axial rear side;

[0006] The camera assembly includes a camera and a transmission module. The camera is disposed at the end of the extended end and communicates with an external device through the transmission module.

[0007] The cleaning assembly includes a nozzle and a liquid supply module. The nozzle is embedded on the side surface of the extended end and the liquid supply module supplies cleaning fluid from inside the cleaner housing.

[0008] The flexible expansion component includes a control module and an airbag module. The airbag module includes a plurality of flexible airbags arranged circumferentially on the surface of the extended end. Two adjacent flexible airbags are arranged close together or spaced apart. Each flexible airbag is independently controlled by the control module to switch between a contracted state and an inflated state.

[0009] When all the flexible airbags are inflated, the outer sides of all the flexible airbags together establish a support surface, the outer diameter of which is larger than the outer diameter of the inserted end;

[0010] Compared to its inflated state, the flexible airbag in its contracted state creates an obstacle avoidance space in the corresponding area.

[0011] In an alternative embodiment, at least one of the nozzles is located between two adjacent flexible airbags, and / or along the axial direction of the cleaner housing, with at least one of the nozzles positioned axially rearward of the airbag module.

[0012] In an optional implementation, the number of flexible expansion components is two or more, and the airbag modules in different flexible expansion components are respectively arranged at different axial positions of the extension end.

[0013] In an optional implementation, at least one of the nozzles is located between two adjacent airbag modules.

[0014] In an optional embodiment, the liquid supply module includes a water pipe and a liquid supply drive unit located inside the cleaner housing. One end of the water pipe is connected to the nozzle, and the other end of the water pipe is connected to a liquid storage tank for storing the cleaning liquid. The liquid supply drive unit is used to pump the cleaning liquid from the liquid storage tank to the nozzle.

[0015] The liquid storage tank is located inside the cleaner housing or on an external device.

[0016] In an optional implementation, the control module includes a pneumatic control unit and an air passage located inside the cleaner housing. One end of the air passage is connected to a corresponding airbag, and the other end of the air passage extends from the operating end of the cleaner housing and is connected to the pneumatic control unit located outside the cleaner housing.

[0017] In an optional implementation, the air pressure control unit is an air supply unit, and the control module further includes a control button corresponding to each air pipeline. The control button is arranged on the surface of the operating end, and each control button is used to control the connection status between the corresponding air pipeline and the air supply unit.

[0018] A vent is provided in the air passage from the control button to the flexible airbag.

[0019] In an optional implementation, the circumferential position of the control button on the operating end is consistent with the circumferential position of the flexible airbag controlled by the control button on the insertion end.

[0020] In an optional implementation, when there are two or more sets of flexible expansion components, multiple flexible airbags located at the same circumferential position at the insertion end of different flexible expansion components share one control button.

[0021] In an optional implementation, multiple flexible airbags in the airbag module are integrated into a single airbag.

[0022] In summary, the visual cleaning device disclosed in this invention gently expands the cavity wall from the inside through the expansion of flexible airbags, allowing the device to contact the organ with a relatively soft, flexible airbag structure. This changes the rigid insertion method of traditional cleaning devices, significantly reducing the patient's physical discomfort and psychological tension, and is particularly suitable for patients with unhealed postoperative wounds or sensitive constitutions. When using a multi-stage expansion structure, it allows for step-by-step insertion, avoiding discomfort caused by a single insertion. Each airbag can be independently controlled to adapt to different cavity shapes. The camera transmits real-time images of the cavity interior, which are then combined with the orientation of the control buttons, enabling the operator to intuitively judge the wound location and operate quickly, achieving a transition from blind to direct vision, improving operational accuracy and safety. By independently controlling each flexible airbag, avoidance space can be created at specific locations, completely avoiding physical contact and pressure on the wound. When using a small-angle airbag design, the wound can be aligned by rotation. The continuous design of multiple airbags further enhances the device's effectiveness. Precise avoidance without rotation allows patients with episiotomy wounds, hemorrhoid lesions, or postoperative sutures to safely receive cleaning treatment. The inflatable flexible airbag fits tightly against the cavity wall to form a sealing barrier, confining the cleaning fluid to a specific area, improving the efficiency of drug utilization, preventing irritation to non-target areas and the risk of deep infection, and preventing backflow of contaminated liquid into deeper areas. The coordinated layout of the nozzle and airbag ensures that the cleaning fluid acts directly on the expanded cavity wall area, guaranteeing the spraying effect. The correspondence between the control buttons and the airbag's orientation, as well as the design of multiple airbags sharing a control button in the same circumference, allows the operator to operate quickly and accurately based on the image display, simplifying the surgical procedure and reducing the difficulty of operation. The vent design avoids negative pressure adhesion caused by sudden airbag contraction, preventing patient pain. The integrated design of the entire airbag and the application of a transparent protective film facilitate replacement and maintenance, protect the camera, and comprehensively improve the safety and hygiene of use.

In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0035] Example 1

[0036] Figure 1 This is a first schematic diagram of the three-dimensional structure of the visualized cleaner according to an embodiment of the present invention. Figure 2 This is a second schematic diagram of the three-dimensional structure of the visualized cleaner according to an embodiment of the present invention. Figure 3 This is a third schematic diagram of the three-dimensional structure of the visualized cleaner according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the cross-sectional structure of the visualized cleaner according to an embodiment of the present invention. In the first schematic diagram of the three-dimensional structure of the visualized cleaner, the airbag module 3 is in a contracted state. In the second schematic diagram of the three-dimensional structure of the visualized cleaner, the airbag module 3 is in an inflated state. In the third schematic diagram of the three-dimensional structure of the visualized cleaner, it is mainly used to show the surface structure of the operating end 32 of the cleaner housing 1.

[0037] This invention discloses a visual cleaner, including a cleaner housing 1, a cleaning component, a camera component, and a flexible expansion component. Through the collaborative design of each component, it achieves flexible expansion and introduction of cavities, visual and precise operation, and selective wound avoidance.

[0038] Cleaner housing 1

[0039] Referring to the first schematic diagram of the three-dimensional structure of the visualized cleaner, the cleaner housing 1 has an insertion end 31 located on the axial front side and an operating end 32 located on the axial rear side. The insertion end 31 is designed as a rod-shaped streamlined curved surface structure with no sharp edges to reduce mechanical stimulation to the cavity wall during insertion; the operating end 32 has a relatively large diameter, forming a belly-shaped area suitable for gripping, and can accommodate components such as the liquid supply module and circuit elements as needed, and is ergonomically designed to facilitate gripping by human hands or robotic arms.

[0040] camera components

[0041] The camera assembly includes a camera 18 and a transmission module 17. The camera 18 is disposed at the end of the insertion end 31 and communicates with external devices through the transmission module 17. The camera 18 faces the head of the insertion end 31 and is used to capture real-time images or videos of the inside of the cavity, reflecting the position where the cleaner is about to be inserted and contacted. The transmission module 17 can transmit the image information to an external display device via wired or wireless means, allowing the operator to observe the internal condition of the cavity on the front side of the cleaner housing 1 in real time, realizing the transformation from blind observation to direct observation and improving operational accuracy.

[0042] Figure 5 This is a three-dimensional structural diagram of the cleaner housing 1 according to an embodiment of the present invention.

[0043] In practice, a transparent sealing end cap 11 is usually provided on the end of the cleaner housing 1 extending into the end 31. The camera 18 is located below the sealing end cap 11. Under the premise of ensuring that the function of the camera 18 is not affected, the sealing and safety of its working environment are guaranteed.

[0044] Cleaning components

[0045] The cleaning assembly includes a nozzle 2 and a liquid supply module. The nozzle 2 is embedded on the side surface of the extension end 31 and provides cleaning fluid from inside the cleaner housing 1 through the liquid supply module. The outer end face of the nozzle 2 is flush with or slightly concave with the outer surface of the cleaner housing 1 to maintain the streamlined shape of the cleaner housing 1 and avoid protrusion that would damage the external structure of the cleaner.

[0046] The liquid supply module includes a water pipe 19 and a liquid supply drive 20 located inside the cleaner housing 1. One end of the water pipe 19 is connected to the nozzle 2, and the other end is connected to a storage tank 22 for storing the cleaning fluid. The liquid supply drive 20 pumps the cleaning fluid from the storage tank 22 to the nozzle 2. The storage tank 22 is located inside the cleaner housing 1 or on an external device. Specifically, the liquid supply module can have a built-in micro-liquid pump and a drug reservoir. The first end of the water pipe 19 is connected to the output end of the micro-liquid pump, and the input end of the micro-liquid pump is connected to the drug reservoir through a suction tube with a gravity ball 23 (in an embodiment of the present invention). Alternatively, the first end of the water pipe 19 can be externally connected to a standard hospital infusion tube or syringe interface. The nozzle 2 can be a single-hole or multi-hole design, and the spray angle can be set to direct or diffused spray as needed.

[0047] Accordingly, in this embodiment of the invention, the liquid storage tank 22 is built into the cleaner housing 1, and the operating end 32 is provided with a replenishment hole 24 communicating with the liquid storage tank 22. The replenishment hole 24 is sealed by a plug 6.

[0048] Flexible expansion components

[0049] The flexible expansion assembly includes a control module and an airbag module 3. The airbag module 3 includes multiple flexible airbags arranged circumferentially on the surface of the extension end 31. The flexible airbags are made of flexible materials, such as medical silicone or latex, and have good biocompatibility and elasticity, expanding with the increase of internal gas volume and gas pressure.

[0050] Basically, the flexible airbag is fitted onto the surface of the insertion end 31 of the cleaner housing 1. The insertion end 31 has air holes 10 in the corresponding area that communicate with the flexible airbag. The airbag is controlled to be inflated or deflated from the inside of the cleaner housing 1 through the air holes 10.

[0051] Adjacent flexible airbags are either tightly fitted or spaced apart. When adjacent flexible airbags are tightly fitted, all flexible airbags in the inflated state form a relatively continuous support surface, effectively sealing the cavity (the embodiment used in Example 1). When adjacent flexible airbags are spaced apart, a gap 54 is formed between the flexible airbags (the embodiment used in Example 2), which can be used to arrange the nozzle 2 or provide additional liquid flow channels. It should be noted that the support surface does not disappear due to the presence of the gap 54. The function of the support surface is to form a support contact surface larger than the outer diameter of the insertion end 31 of the cleaner housing 1, adjusting the rigid or semi-rigid contact between the cleaner housing 1 and the inner cavity to the flexible contact of the flexible airbags, reducing user discomfort. In addition, when there are multiple sets of flexible expansion components, the flexible airbags in different flexible expansion components can adopt different implementation structures, thereby achieving diversified functions through various combinations of flexible airbag actions.

[0052] Essentially, each of the flexible airbags is individually controlled by the control module to switch between a contracted and inflated state. When all the flexible airbags are inflated, their outer surfaces collectively establish a support surface, the outer diameter of which is larger than the outer diameter of the insertion end 31. This provides flexible support and positioning for the cavity wall, reducing user discomfort. When adjacent flexible airbags are positioned close together, the airbag module 3 can form a sealing barrier during cleaning, preventing the cleaning fluid from flowing deeper. In the contracted state, the flexible airbags create a clearance space in the corresponding area. When a wound is observed on the inner wall of the cavity through the camera assembly, the control module can be operated to keep the corresponding flexible airbag in a contracted state while keeping the flexible airbags in other positions inflated support. This allows the cleaner to maintain overall support while creating a recessed clearance area in a specific location, completely avoiding physical contact and pressure on the wound.

[0053] It should be noted that when two adjacent flexible airbags are spaced apart, in addition to using the contraction of the flexible airbags to form an avoidance zone, the gap between the two flexible airbags can also be used to avoid the wound.

[0054] Depending on the functional requirements, the flexible airbag in an airbag unit module can adopt different combination structures:

[0055] Figure 6 This is a top view of the first airbag assembly structure according to an embodiment of the present invention. It should be noted that... Figure 6 The first airbag assembly structure shown is not related to Figure 1 The three-dimensional structure of the visualized cleaner shown corresponds to that of the [device], and can be understood as [the [device]... Figure 1 The airbag module in the visualized cleaner structure is replaced with the first airbag assembly structure.

[0056] In the first airbag assembly structure, the airbag module 3 of the flexible expansion component includes two flexible airbags arranged closely together circumferentially, named airbag A 51 and airbag B 52, respectively. Airbag A 51 has a circumferential angle exceeding 180° (generally recommended to exceed 240°), while airbag B 52 has a circumferential angle less than 180°. With this structure, airbag B 52 is specifically designed to avoid wounds, while airbag A 51 focuses on support. When the wound location is observed through camera 18, the entire visual cleaner needs to rotate axially by rotating the cleaner housing 1, thereby rotating airbag B 52 to the position corresponding to the wound. Then, airbag B 52 is contracted to avoid the organ wound.

[0057] Figure 7 This is a top view of the second airbag assembly structure according to an embodiment of the present invention. It should be noted that... Figure 7 The second airbag assembly structure shown is not related to Figure 1 Corresponding to the visualized cleaner structure shown, the actual implementation of the second airbag assembly structure can be understood as follows: Figure 1 The airbag module in the visualized cleaner structure shown is replaced with the first airbag combination structure. In some application scenarios, the implementation of the second airbag combination structure is similar to that of the airbag module in the visualized cleaner illustrated in Embodiment 2.

[0058] In the second airbag assembly structure, the airbag module 3 of the flexible expansion component includes multiple discretely arranged flexible airbags (such as C-airbags 53), with gaps 54 between adjacent flexible airbags. Compared with the first airbag assembly structure, because there are gaps 54 between the airbags, these gaps 54 can be used to set up nozzles 2. This allows the expansion of the airbags to open up the internal organs of the corresponding areas, expanding the areas requiring medication spraying and specifically spraying the medication onto the inner walls of the organs between the airbags, ensuring effective spraying.

[0059] Figure 8 This is a top view of the third airbag assembly structure in an embodiment of the present invention. The third airbag assembly structure is the structure used in the airbag module of this embodiment of the present invention.

[0060] In the third airbag assembly structure, the airbag module 3 of the flexible expansion component includes three or more flexible airbags (such as airbag D 55) continuously and closely attached circumferentially, with the circumferential angle of a single flexible airbag being less than 120°. Compared with the first airbag assembly structure, when the number of airbags in the flexible expansion component is more than three, each airbag can adopt the same structure, and each airbag can avoid the organ wound by contraction. In actual operation, compared with the first airbag assembly structure, during the process of introducing the visual cleaner into the organ, there is no need to adjust the circumferential position of the cleaner housing 1, which can avoid the rotational movement of the cleaner housing 1 from rubbing against the inner wall of the organ and causing discomfort to the patient, and can also simplify the operation of the visual cleaner.

[0061] By comparing the three types of airbag combination structures, the functional characteristics of various forms of airbag combination structures can be obtained: When the airbags in the airbag combination structure are arranged close together, all airbags, when inflated, isolate and cut off the organ passage by adhering tightly to the organ's inner wall. In this case, when the nozzle 2 sprays liquid, the liquid will not flow into the depth of the organ due to the blockage of the organ passage. When the airbags in the airbag combination structure are arranged discretely, nozzles 2 can be set in the gaps 54 between the airbags. The expansion of the airbags can expand the internal organs of the corresponding areas, opening up the areas where the medicine needs to be sprayed, and spraying the medicine on the inner walls of the organs between the airbags in a targeted manner to ensure the spraying effect. When the number of airbags in the airbag combination structure is small, the airbags need to be specially designed to ensure that the required functions are achieved. When the number of airbags in the airbag combination structure is large, the same structure can be used between different airbags. Moreover, by increasing the number of airbags, more precise wound avoidance actions and more flexible organ inner wall support actions can be achieved.

[0062] Multi-level expansion structure

[0063] Figure 9 This is a partial magnified front view schematic diagram of the visual cleaner according to an embodiment of the present invention. The schematic diagram is used to show the partial structure of the visual cleaner having two sets of flexible expansion components. The airbag modules 3 in the two sets of flexible expansion components are respectively named the front airbag unit 61 and the rear airbag unit 62.

[0064] Preferably, there are two or more sets of flexible expansion components, and the airbag modules 3 in different flexible expansion components are respectively arranged at different axial positions of the extension end 31 to form a multi-level expansion structure distributed along the axial direction. This multi-level arrangement can form multiple support points at different axial positions of the cleaner housing 1, which has two important functions in this embodiment of the invention.

[0065] The first function is, as described above, when the airbags in the airbag assembly structure are arranged close together, when all the airbags expand, they isolate and cut off the organ passage by adhering tightly to the inner wall of the organ. When there are two or more sets of flexible expansion components, two sealing barriers can be formed to completely seal the local area inside the organ. At this time, the cleaning fluid sprayed from the nozzle 2 can be temporarily stored in the sealed area, forming a function of soaking a specific area, which has special effects in some application scenarios.

[0066] The second function is to implement a new method for introducing a visual cleaner. When introducing the visual cleaner, the airbag modules 3 are first adjusted to the contracted state. In the initial stage of introduction, the insertion end 31, which contains the area of ​​two airbag modules 3, needs to be introduced into the organ first.

[0067] After the insertion ends 31 of the two airbag modules 3 are introduced, the foremost flexible airbag is first expanded to gently open the inner wall of the cavity. At this time, the foremost flexible module completely supports the inner wall of the cavity. Since the tissue of the cavity organ is continuous, a funnel-shaped space will be formed at the front end of the visual cleaner. This funnel-shaped space can accommodate the insertion end 31 of the visual cleaner housing 1 without contact. At this time, the foremost flexible module is kept in an expanded state. Then, the visual cleaner is slowly sent in a certain distance (the insertion end 31 makes slight contact or no contact with the inner wall of the funnel-shaped space). Then, the relatively rear flexible module airbag module 3 is expanded to form a new support point. It should be noted that during the process of introducing the whistle-shaped space into the cleaner housing 1, due to the friction between the airbag module 3 and the inner wall of the organ, as well as the deformation capability of the flexible airbag itself, the frontmost airbag module 3 does not move with the overall displacement of the cleaner, but rather undergoes a movement similar to local deflection. There is no relative movement between the surface of the flexible airbag and the inner wall of the organ; only the shape and position of the contact surface change. The user mainly feels the sensation of the flexible airbag slowly expanding the organ cavity wall, rather than the discomfort caused by friction.

[0068] When the rear airbag module 3 expands, the septic tank 1 uses the rear airbag module 3 to form a new support point. At this time, the frontmost airbag module is controlled to contract. Since the septic tank 1 has been extended a certain distance, the contracted airbag module 3 will move to a new position following the displacement of the septic tank 1. Then, the frontmost airbag module is controlled to open, and the frontmost airbag module will contact the inner wall of the organ at the new position (the contact position is deeper than the first contact position with the inner wall of the organ), forming a new funnel-shaped space. In this case, the rear airbag module is controlled to contract, and then the extension operation of the septic tank 1 is performed.

[0069] Following the above-mentioned cyclical operation (preferably using a robotic arm to guide the cleaning device housing 1), the cleaning device housing 1 can be guided as a whole to the preset depth position of the organ. The cleaning device housing 1 adopts a step-by-step guidance method of first expanding and then guiding, which avoids mechanical friction and pressure caused by rigid insertion and significantly reduces the patient's physiological discomfort.

[0070] Nozzle 2 setting position

[0071] Nozzle 2 is used to spray cleaning fluid. As the cleaning fluid flows past the inner wall of the organ, it comes into contact with the inner wall and performs the required function according to its mechanism of action. Depending on the arrangement of the airbag modules 3, different positions of the nozzle 2 can achieve different additional functions. Furthermore, at least one nozzle 2 is located between two adjacent airbag modules 3. When using multi-stage airbag modules 3, the nozzle 2 can be positioned in the axially spaced area between adjacent airbag modules 3 to form precise cleaning of specific areas. Simultaneously, along the axial direction of the cleaner housing 1, at least one nozzle 2 is positioned axially rearward of the airbag module 3, so that after the airbag module 3 expands and seals the cavity, the cleaning fluid sprayed from the nozzle 2 is confined within the sealed area.

[0072] Control module

[0073] The control module includes a pneumatic control unit and an air passage 16 located inside the cleaner housing 1. One end of the air passage 16 is connected to a corresponding airbag, and the other end of the air passage 16 extends from the operating end 32 of the cleaner housing 1 and is connected to the pneumatic control unit located outside the cleaner housing 1. In this embodiment of the invention, the operating end 32 is provided with a corresponding air passage interface 5.

[0074] The air pressure control unit can be an air supply unit, such as a miniature air pump, an air tank, or an external air source interface, used to control the contraction and expansion of the corresponding airbag by controlling the gas pressure and / or gas volume. The air pressure control unit also includes an air pressure regulating unit for adjusting the output air pressure. The air pressure regulating unit can use a mechanical pressure reducing valve or an electronic proportional valve to achieve stepless pressure regulation within a preset air pressure range to adapt to the tissue compliance of different patients.

[0075] Preferably, the control module further includes a control button 4 corresponding to each air passage 16. The control button 4 is arranged on the surface of the operating end 32, and each control button 4 is used to control the connection state between the corresponding air passage 16 and the air supply unit. The control button 4 includes a switch control terminal 14 and a switch action terminal 15 controlled by the switch control terminal 14. The switch control terminal 14 is exposed on the surface of the cleaner housing 1, and the switch action terminal 15 acts on the corresponding air passage 16. When the switch control terminal 14 is not triggered, the switch action terminal 15 remains in a first state, and the air passage 16 corresponding to the switch action terminal 15 is in a connected state; when the switch control terminal 14 is triggered, the switch action terminal 15 remains in a second state, and the air passage 16 corresponding to the switch action terminal 15 is in a closed state.

[0076] To ensure the flexible airbag can contract even when the airway 16 is shut off, a vent is provided in the airway 16 from the control button 4 to the flexible airbag. When the control button 4 cuts off the airway, the gas inside the corresponding flexible airbag can be released through the vent, allowing the flexible airbag to contract and avoid the wound. The size of the vent is designed so that during normal air supply, the airbag can maintain the required pressure and remain inflated because the supply pressure is greater than the release rate. When the airway 16 is shut off, the airbag contracts according to the compression, and the gas required for contraction is released through the vent. The airbag exerts almost no force on the outside, reducing discomfort for the user or patient. It should be noted that in this embodiment of the invention, since the liquid storage chamber 22 is located inside the cleaner housing 1, the airway 16 passes through the liquid storage chamber 22. To prevent the cleaning fluid from entering the airway 16, the vent needs to be located on the airway 16 away from the area of ​​the liquid storage chamber 22.

[0077] Preferably, the circumferential position of the control button 4 on the operating end 32 corresponds to the circumferential position of the flexible airbag controlled by the control button 4 on the insertion end 31. This orientational correspondence allows the operator to intuitively determine the wound location based on the image displayed by the camera component and quickly operate the corresponding control button 4 without needing to memorize complex correspondences, thus achieving precise control. Preferably, all the control buttons 4 are centrally arranged at the rear of the cleaner housing 1, forming a control panel for easy operation.

[0078] Furthermore, when there are two or more sets of the flexible expansion components, multiple flexible airbags located at the same circumferential position on the insertion end 31 share one control button 4. That is, multiple flexible airbags at different axial positions but within the same axial plane are synchronously controlled by the same control button 4. This design simplifies the control structure and allows for synchronous inflation and deflation of multiple airbags at the same axial position, ensuring that the flexible airbags at that position can contract uniformly to avoid the wound surface in that area and reduce the frequency of operations.

[0079] Integrated design of the overall airbag 9

[0080] Figure 10 This is a three-dimensional structural schematic diagram of the overall airbag 9 according to an embodiment of the present invention.

[0081] Preferably, the multiple flexible airbags in the airbag module 3 are integrated into a single airbag 9. The single airbag 9 is divided into multiple air chambers 8 along the circumference, each air chamber 8 forming one of the flexible airbags. The air chambers 8 are airtightly isolated from each other and are connected to the corresponding air passage 16 through independent nozzles or air holes 10. The nozzles or air holes 10 are provided on the cleaner housing 1. The outer end of the nozzle is connected to the corresponding air chamber 8, and the inner end of the nozzle is connected to the end of the air passage 16 inside the cleaner housing 1.

[0082] This integrated design improves structural compactness and sealing reliability, reduces the number of parts, and facilitates installation and replacement. The integral airbag 9 can be made of elastic material and is tightly fitted onto the extension end 31 of the cleaner housing 1 through elastic deformation. The integral airbag 9 has an annular opening on its inner side, and the outer end of the air nozzle communicates with the corresponding air chamber 8 in the integral airbag 9 through the annular opening. This tight-fitting connection facilitates the installation, replacement, and maintenance of the airbag, while ensuring reliable communication between the air nozzle and the air chamber 8. The integral airbag 9 is generally used as a consumable, which improves the replacement efficiency of the airbag module 3 and effectively avoids secondary contamination.

[0083] Furthermore, the front opening of the overall airbag 9 is sealed by a transparent protective film 7. The primary purpose of this transparent protective film 7 is to ensure that the airbag as a whole will not be moved downwards during the introduction of the cleaner, by limiting the position of the transparent protective film 7 and the end of the insertion end 31 of the cleaner housing 1, thus ensuring the stability of the structure and function of the overall airbag 9. At the same time, the transparent protective film 7 can protect the internal camera 18 from cleaning fluid contamination without affecting the visual observation of the camera 18, ensuring the visualization effect of the cleaning process. A slot can be provided at a preset position at the front end of the cleaner housing 1 for the lower edge of the overall airbag 9 to be inserted, and the upper edge of the overall airbag 9 is sealed by the transparent protective film 7 to form a limit, ensuring the stability of the overall airbag 9 during the introduction and removal of the cleaner. In addition, an annular groove 12 is provided at a preset position on the insertion end 31 of the cleaner housing 1 for the rear end structure of the overall airbag 9 to be inserted, so as to prevent the overall airbag 9 from falling out when the cleaner housing 1 is removed from the human body. Combined with the sealing properties of the transparent protective film 7, it can ensure that the interior of the overall airbag 9 is completely separated from the human body, and prevent pollutants from entering the air hole 10.

[0084] Power supply module 21

[0085] In addition, for electrical equipment that needs to be installed inside the cleaner housing, various forms of power supply modules 21, such as battery power supply modules and external power supply modules, can be installed inside the cleaner housing as needed. In actual implementation, it can be implemented according to existing technology, and this invention will not provide additional explanation.

[0086] Working principle

[0087] Taking a visual cleaner employing two sets of flexible expansion components (named the front flexible expansion component and the rear flexible expansion component, respectively) as an example, its workflow is as follows:

[0088] Initial introduction: Control all airbag modules 3 to be in a contracted state, and initially introduce the retracted end 31 of the cleaner into the target cavity (such as the vaginal opening or anal opening) until the airbag module 3 in the subsequent flexible expansion assembly enters the target cavity. At this time, all flexible airbags are in an uninflated or slightly pressurized state, and the outer diameter of the retracted end 31 of the cleaner housing 1 is kept at its minimum, which is convenient for initial placement.

[0089] Expansion and positioning: Control the expansion of the airbag module 3 in the front flexible expansion component to open the inner wall of the organ in the corresponding area, and ensure that the airbag module 3 in the rear flexible expansion component is in a contracted state; at this time, a funnel-shaped opening space is formed in the front area of ​​the cleaner housing 1. On the one hand, the opening space is conducive to the observation of the camera component, and on the other hand, it prepares for the subsequent import action.

[0090] Observation of introduction: Driven by the operation end 32, the cleaner housing 1 is introduced forward. Observation is performed by the camera component. The introduction action stops before or when the end of the insertion end 31 contacts the inner wall of the organ. During this stage, the airbag module 3 in the front flexible expansion component does not move with the overall displacement of the cleaner housing 1. The trumpet-shaped expansion space shape established by the front flexible expansion component remains basically unchanged.

[0091] Secondary positioning: In the aforementioned steps, the airbag module 3 in the rear flexible expansion assembly moves synchronously with the scavenger housing 1. In this step, the airbag module 3 in the rear flexible expansion assembly expands the inner wall of the organ in the corresponding area to form an expansion support. On the one hand, this avoids the organ from being completely pressed against the scavenger housing 1, thus ensuring the user's experience and providing a spatial environment for the airbag module 3 in the front flexible expansion assembly to move with the scavenger housing 1. On the other hand, it is necessary to form a new support point between the scavenger housing 1 and the organ to prevent the relative position of the scavenger housing 1 and the organ from changing when the airbag module 3 in the front flexible expansion assembly contracts, thus ensuring the effectiveness of the induction process.

[0092] Pre-stage detachment: After the secondary positioning step, the airbag module 3 in the front flexible expansion assembly will move forward with the cleaner housing 1 when it contracts. After the pre-stage detachment step, the expansion positioning to pre-stage detachment step is repeated, which can send the extension end 31 of the cleaner housing 1 to the preset depth position of the organ. During this process, if the wound on the organ is observed through the camera component, the flexible airbag at the corresponding position can be controlled to contract to avoid the wound during the introduction of the cleaner housing 1. It should be noted that the visualization cleaner of this embodiment does not measure the introduction depth structure. The specific introduction depth can be calculated by observing the length of the cleaner housing 1 left outside the body.

[0093] Cleaning preparation: After the cleaner housing 1 is introduced to the target position, the expansion and contraction states of all flexible airbags are controlled according to the cleaning requirements. For example, the airbag module 3 in the flexible expansion component is adjusted to the expansion state to close the organ cross section, which can ensure that the cleaning fluid does not flow into the depth of the organ. The state and function of the airbag module have been fully explained in the foregoing.

[0094] Cleaning: Cleaning fluid is sprayed out through nozzle 2.

[0095] Exit: After cleaning is complete, operate all control buttons 4 to cut off the air circuit. Each flexible airbag will vent and contract through the vent, causing the airbag to contract. Then, gently remove the cleaner housing.

[0096] Example 2

[0097] Figure 11 This is a three-dimensional structural diagram of the cleaning device according to an embodiment of the present invention.

[0098] and Figure 7 Similar to the second airbag assembly structure shown, in this embodiment of the invention, two adjacent flexible airbags (named E airbag 56) in the airbag module are spaced apart. Correspondingly, a gap 54 is formed between the two adjacent flexible airbags. This gap 54 can be used to allow the wound surface to pass through, and can also be used to install and set the nozzle.

[0099] When the airbag module adopts the visual cleaner implementation structure of the present invention, preferably, the flexible airbag extends along the axial direction of the cleaner housing to form a strip structure, that is, a single flexible airbag adopts a strip structure. When the visual cleaner extends into the organ, the extension end and the inner wall of the organ will be divided into several relatively independent flow channel intervals in the circumferential direction through the interval of the strip structure flexible airbag.

[0100] Correspondingly, in addition to avoiding the wound surface through the contraction of the flexible airbag, the airbag module structure of this embodiment of the invention also has a relatively independent flow channel area. When the cleaning fluid is sprayed from the nozzle, the cleaning fluid will only flow through the corresponding flow channel area and will not flow to other circumferential areas, thus making the cleaning of the cleaning fluid more targeted.

[0101] Correspondingly, referring to the accompanying drawings, the visual cleaner of this embodiment of the invention has multiple nozzles arranged circumferentially at the insertion end. The cleaning fluid spraying action of each nozzle can be precisely and separately controlled by the liquid supply module, which improves the targeting of the cleaning fluid spraying from the nozzle, which is beneficial to improve the targeting of the cleaning fluid spraying, improve the efficiency of cleaning fluid use, and save cleaning fluid.

[0102] Correspondingly, unlike the working mode of the visual cleaner in Embodiment 1, during the insertion of the cleaner housing, the visual cleaner of this embodiment can avoid the wound by utilizing gaps or by utilizing the contraction of the flexible airbag. In actual implementation, when the wound is located in the gap position, the gap is used to avoid the wound; when the wound is located in the flexible airbag position, the contraction of the flexible airbag is used to avoid the wound. This avoids the need to twist the cleaner housing and reduces discomfort for the user or patient.

[0103] It should be noted that, in the visual cleaner of this embodiment of the invention, except for the difference in the structure and setting of the airbag module itself from the visual cleaner of embodiment one, the rest of the structure is consistent with the visual cleaner of embodiment one in terms of function. The specific physical structure can be adapted according to the needs, and will not be described again in this embodiment of the invention.

[0104] In summary, the visual cleaning device disclosed in this invention gently expands the cavity wall from the inside through the expansion of flexible airbags, allowing the visual cleaning device to contact the organ with a relatively soft flexible airbag structure. This changes the rigid insertion method of traditional cleaning devices, significantly reducing the patient's physical discomfort and psychological tension, and is particularly suitable for patients with unhealed postoperative wounds or sensitive constitutions. When using a multi-stage expansion structure, it is possible to achieve step-by-step introduction by first expanding and then entering, avoiding the discomfort caused by a single insertion. Moreover, each airbag can be independently controlled to adapt to different cavity shapes. The camera transmits real-time images of the cavity interior, which are combined with the orientation correspondence of the control buttons, allowing the operator to intuitively judge the wound location and operate quickly, realizing the transformation from blind to direct vision, improving the accuracy and safety of operation. By separately controlling each flexible airbag, avoidance space can be formed in a specific direction, completely avoiding physical contact and pressure on the wound. When using a small-angle airbag design, the wound can be aligned by rotation. The use of multiple airbags in a continuous design... The timing function allows for precise avoidance without rotation, enabling patients with episiotomy wounds, hemorrhoid lesions, or postoperative sutures to safely receive cleaning treatment. The inflatable flexible airbag fits tightly against the cavity wall to form a sealed barrier, confining the cleaning solution to a specific area, improving drug utilization efficiency, preventing irritation to non-target areas and the risk of deep infection, while also preventing backflow of contaminated liquid into deeper areas. The coordinated layout of the nozzle and airbag ensures that the cleaning solution acts directly on the expanded cavity wall area, guaranteeing the spraying effect. The corresponding position of the control buttons and airbags, as well as the design of multiple airbags sharing a control button in the same circumference, allows the operator to operate quickly and accurately based on the image display, simplifying the surgical procedure and reducing the difficulty of operation. The vent design avoids negative pressure adhesion caused by sudden airbag contraction, preventing patient pain. The integrated design of the entire airbag and the application of a transparent protective film facilitate replacement and maintenance, and protect the camera, comprehensively improving safety and hygiene.

[0105] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
