Description

Technical Field

[0001] This invention relates to the field of endoscope-related technologies, and in particular to a wireless endoscope with a cleaning function. Background Technology

[0002] As a key instrument for direct visualization and minimally invasive surgery within the body's natural cavities, the clarity of the image directly determines the diagnostic and treatment outcomes. In complex environments such as the digestive, respiratory, and genitourinary tracts, the lens inevitably comes into contact with contaminants such as blood, mucus, and tissue debris, leading to blurred vision, forced interruption of the procedure, and impacting diagnostic and treatment efficiency and safety.

[0003] Currently, several endoscopic designs integrating flushing functions exist in the industry. For example, Chinese Patent Publication No. CN106572793A discloses an endoscopic device including an elastography recording device, gas inflation, and a device for rhythmically changing the volume of the gas. The endoscopic device may be equipped with an illumination device and an image sensor, which are arranged and aligned in such a way that they can illuminate and image the area in the body cavity adjacent to the gas inflation. Therefore, the information detected by the elastography recording device can be combined with the image information to quickly and reliably understand the state of the tissue under consideration.

[0004] However, existing technologies still have significant shortcomings in practical applications: the aforementioned endoscopic products themselves do not integrate any irrigation function, and intraoperative lens cleaning relies entirely on external wiping, which is cumbersome and affects continuity. Although a few high-end devices or external accessories have attempted to introduce irrigation functions, existing irrigation solutions still have significant limitations. On the one hand, the irrigation mode is singular, usually only used for body cavity irrigation, with a fixed water flow path, making it impossible to quickly switch to a directional flow channel specifically for lens cleaning when the lens is contaminated. On the other hand, during the instrument insertion stage, the lens generally lacks an effective physical protective structure, making it susceptible to contamination from the initial stage. Based on this, this application proposes a wireless endoscope with a cleaning function. Summary of the Invention

[0013] As a preferred embodiment of the present invention, a protective component is provided inside the upper end of the main shell to protect the lens assembly from contamination. The protective component includes a protective cover, which is built into the main shell to protect the lens assembly from contamination. An embedded cover is also embedded in the upper end of the main shell.

[0014] As a preferred embodiment of the present invention, the protective cover is made of rubber and consists of an inner frame and an anti-pollution cover, with a frustum-shaped anti-pollution cover installed inside the inner frame.

[0038] The following is in conjunction with the appendix Figures 1 to 15 This application will be described in further detail.

[0039] This application discloses a wireless endoscope with a cleaning function. This application protects the lens assembly 6 from contamination when it is inserted into the body, reducing the possibility of its lens becoming blurry. When the lens assembly 6 is used for endoscopic operations, its lens can be cleaned by diverting water and rinsing, ensuring the clarity of the lens during operation.

[0040] Example 1, refer to Figures 1 to 3 , Figure 12 , Figure 14As shown, this embodiment discloses a wireless endoscope with a cleaning function, including a liquid bottle 1, an intermediate shell 11, a main shell 12, an outlet 13, a water pump 21, a water spray pipe 22, a water suction pipe 23, a water suction head 24, a nozzle assembly 4, a lens assembly 6, a main control module 7, a lithium battery pack 8, and function buttons 9. The liquid bottle 1 is connected to the main shell 12 through the intermediate shell 11. The upper outer surface of the silicone main shell 12 is provided with outlet holes 13 evenly distributed around its circumference. The water pump 21 is built into the lower part of the main shell 12. In the designated position, the outlet of the water pump 21 is connected to the nozzle assembly 4 via the spray pipe 22, and the suction port of the water pump 21 is connected to the suction head 24 via the suction pipe 23. The suction head 24 extends into the liquid bottle 1. The nozzle assembly 4 and the spray hole 13 are positioned correspondingly. The lens assembly 6 is built into the upper part of the main housing 12. The lens assembly 6 collects image information of the detection area in real time. The lens assembly 6, water pump 21, main control module 7, lithium battery pack 8, and function button 9 are electrically connected.

[0041] In actual operation, the application is inserted into the patient's body. During insertion, the water pump 21 delivers the rinsing fluid in the liquid bottle 1 to the nozzle assembly 4 and finally sprays it out from the spray hole 13 to rinse the patient's body. At the same time, the lens assembly 6 is used to view the patient's body.

[0042] It is important to note that the main control module 7 is a PCB motherboard, i.e., a printed circuit board, which is the electronic control core of the wireless endoscope. It is made of insulating substrate material, and precise copper foil conductive lines are etched on the surface through a specific process. These lines are responsible for electrical connection and signal transmission, and provide a stable mechanical mounting platform and electrical interconnection nodes for various electronic components (such as chips, capacitors, resistors, etc.). They are the basic carrier for realizing circuit function integration and equipment miniaturization.

[0043] The lens assembly 6 used is an existing imaging component, which typically includes an optical lens, an image sensor and necessary packaging structure. It is used to acquire image information of the area to be observed and is the core module for realizing the visual observation function. Its specific specifications and selection can be determined according to actual diagnostic and treatment needs.

[0044] Reference Figure 7 As shown, a movable cover 131 is movably disposed inside the spray hole 13. The movable cover 131 has water spray holes evenly distributed along its circumference. The cleaning channel 14 located above the spray hole 13 is opened in the interlayer of the main shell 12.

[0045] Since this application involves intra-body procedures, the direct ejection of the flushing fluid through the nozzle 13 may irritate the inner wall of the body. To avoid pressure stimulation when the flushing fluid is directly ejected, this application provides a movable cover 131 inside the nozzle 13, and evenly distributes water spray holes around the movable cover 131. When the water pump 2 is not delivering flushing fluid, the movable cover 131 provides a certain degree of shielding against the nozzle 13, preventing internal tissues or secretions from accidentally entering the channel and causing blockage. When the water pump 2 starts delivering flushing fluid, the liquid pressure acts on the inner side of the movable cover 131, pushing the movable cover 131 slightly outward from the main shell 12. At this time, the flushing fluid can be ejected in the form of multiple fine water streams through the water spray holes distributed around the movable cover 131. The ejection trajectory is close to the inner wall and will not be perpendicular to the inner wall, significantly reducing the impact force of the water flow on the inner wall per unit area, thereby effectively reducing the stimulation and discomfort that may be caused to the patient during the flushing process.

[0046] Reference Figure 7 , Figure 9 , Figure 10 As shown, this application takes into account the possibility that the lens of the lens assembly 6 may become blurred due to foreign objects during endoscopy. Therefore, the structure of the nozzle assembly 4 is further improved. The specific structure is as follows: the nozzle assembly 4 includes a lifting block 31, with a reversing cavity 32 inside the lifting block 31. The lower end of the reversing cavity 32 is connected to the upper end of the water spray pipe 22. The lifting block 31 is mounted on the upper end of the electric push rod 33, which is mounted in the middle of the main housing 12. The upper end of the reversing cavity 32 is connected to the lower end of the water supply channel 42. The inner core head 41 is located inside the inner core head 41. The inner core head 41 and the movable sleeve 43 are connected by an inner and outer sliding connection. The position between the inner core head 41 and the movable sleeve 43 is temporarily locked by a locking unit 44. The lower periphery of the movable sleeve 43 is evenly provided with spray outlets 45, and the upper periphery of the movable sleeve 43 is evenly provided with cleaning ports 46. A return spring 47 is connected between the upper end of the movable sleeve 43 and the inner core head 41. The upper end of the movable sleeve 43 is connected to the lens assembly 6 through a lens plate. A filter screen 461 is provided inside the cleaning port 46.

[0047] Reference Figure 9 , Figure 10As shown, the locking unit 44 includes a push-out member 441, which is elastically slidably disposed in an internal groove opened in the side wall of the inner core head 41. A snap-fit ​​member 442, which forms a pressing fit with the push-out member 441, is slidably disposed in an active groove opened in the side wall of the active sleeve 43. It should be noted that when the active groove and the snap-fit ​​groove 121 are not aligned, the outer part of the snap-fit ​​member 442 is always pressed by the inner wall of the main shell 12, so that the outer half of the snap-fit ​​member 442 is in the active groove, while the inner half of the snap-fit ​​member 442 is snapped into the internal groove, thereby temporarily locking the position of the active sleeve 43 and the inner core head 41. The main shell 12 has a snap-fit ​​groove 121 inside, and the snap-fit ​​groove 121 corresponds to the position of the snap-fit ​​member 442. The lower end slope of the snap-fit ​​groove 121 gradually slopes downward from the outside to the inside. The snap-fit ​​groove 121 is located above the ejection hole 13. After the electric push rod 33 completes the first movement of the nozzle assembly 4 and lens assembly 6, the movable slot and the locking slot 121 are aligned. Under the elastic action, the pusher 441 pushes the locking member 442 completely out of the inner slot. At this time, the outer half of the locking member 442 will be locked into the locking slot 121, so that the movable sleeve 43 and the inner core head 41 are in position, and the movable sleeve 43 cannot continue to rise. At this time, the nozzle outlet 45 and the alignment port on the side of the water supply channel 42 are still aligned. Even if the flushing liquid enters the water supply channel 42 later, the inner core head 41 may be displaced due to the impact force, causing the alignment port on the side of the water supply channel 42 and the nozzle outlet 45 to be misaligned, resulting in a reduction in the delivery volume. However, the reset spring 47 provided in this application tends to keep the inner core head 41 in its original position, thereby reducing the possibility of misalignment in the current state.

[0048] During the actual adjustment process, after insertion is completed, the electric push rod 33 drives the nozzle assembly 4 and lens assembly 6 to move towards the protective assembly 5 until the nozzle outlet 45 is aligned with the nozzle hole 13 (at this time, the nozzle outlet 45 and the alignment port on the side of the water supply channel 42 are aligned, and the position between the inner core head 41 and the movable sleeve 43 is unlocked). The water pump 21 delivers the rinsing fluid in the liquid bottle 1, which passes through the reversing cavity 32, the water supply channel 42, and the nozzle outlet 45 in sequence before being sprayed out from the nozzle hole 13. During the endoscopy, if the lens is found to be blurry, the electric push rod 33 drives the unlocked inner core head 41 to rise to the highest position. At this time, the alignment port on the side of the water supply channel 42 is aligned with the lower end of the cleaning port 46 and the cleaning channel 14. The water pump 21 delivers the rinsing fluid in the liquid bottle 1 into the cleaning channel 14, and finally sprays it out from the cleaning hole 524, thereby cleaning the lens of the lens assembly 6.

[0049] Reference Figure 7 , Figure 8As shown, this application takes into account the possibility of foreign objects directly contaminating the lens assembly 6 when inserted into the body. This application provides a protective component 5 and a retractable lens assembly 6. The protective component 5 is provided inside the upper end of the main shell 12 to protect the lens assembly 6 from contamination. The protective component 5 includes a protective cover 51, which is built into the main shell 12 to protect the lens assembly 6 from contamination. An embedded cover 52 is embedded in the upper end of the main shell 12. The protective cover 51 is made of rubber and consists of an embedded frame 511 and a contamination-proof cover 512. The contamination-proof cover 512 with a frustum structure is installed inside the embedded frame 511.

[0050] Reference Figure 7 As shown, the embedded cover 52 includes a connecting cover 521. The connecting cover 521 has alignment holes 522 evenly distributed around its circumference. A limiting cover 523 is slidably disposed inside the connecting cover 521. The limiting cover 523 has cleaning holes 524 evenly distributed around its circumference. The cleaning holes 524 have a structure that gradually slopes downward from the outside to the inside. The positions of the output port at the upper end of the cleaning channel 14, the alignment hole 522, and the cleaning hole 524 correspond to each other.

[0051] During the actual insertion process, the anti-contamination cover 512 provided in this application protects the retracted lens assembly 6, reducing the possibility of direct contamination. After insertion, the nozzle assembly 4 and lens assembly 6 are moved toward the protective assembly 5 by the electric push rod 33. Since the protective cover 51 is made of rubber, the lens assembly 6 can be easily squeezed through the anti-contamination cover 512 and continue to move, thereby supporting the limiting cover 523 until the alignment hole and cleaning hole are aligned.

[0052] Reference Figure 13 , Figure 15 As shown, a motherboard mounting plate 122 is provided at the lower end of the main shell 12. A main control module 7 is installed on the motherboard mounting plate 122. An indicator light unit 124 is installed on the main control module 7123. A charging hole 125 is provided on the rear outer wall of the main shell 12. The lithium battery pack 8 is electrically connected to the charging hole 125 for receiving external power for charging. A plug 1251 is provided on the outside of the charging hole 125 to prevent dust.

[0053] Working principle:

[0054] Step 1: Insert this application into the patient's body. During insertion, the lens assembly 6 is protected against contamination by the protective component 5.

[0055] Step 2: After insertion is complete, the electric push rod 33 drives the nozzle assembly 4 and lens assembly 6 to move towards the protective assembly 5 for the first time until the nozzle assembly 4 is aligned with the nozzle 13. At this time, the lens assembly 6 is squeezed out from the protective assembly 5 and reaches the endoscope position. The water pump 21 delivers the rinsing fluid in the liquid bottle 1 to the nozzle 13 and sprays it out, thereby rinsing the patient's body. At the same time, the patient's body is viewed through the lens assembly 6.

[0056] Step 3: During the endoscopy, when the lens is found to be blurry, the electric push rod 33 continues to drive the unlocked inner core head 41 to the highest position. At this time, the alignment port on the side of the water supply channel 42 is aligned with the lower end of the cleaning port 46 and the cleaning channel 14. The rinsing liquid in the liquid bottle 1 is delivered to the cleaning channel 14 by the water pump 2 and finally sprayed out from the cleaning hole 524, thereby cleaning the lens of the lens assembly 6.

[0057] Example 2: This example discloses a wireless endoscope with a cleaning function, comprising a liquid bottle 1, an intermediate shell 11, a main shell 12, an outlet 13, a water pump 21, a spray pipe 22, a suction pipe 23, a suction head 24, a nozzle assembly 4, a lens assembly 6, a main control module 7, a lithium battery pack 8, and function buttons 9. The liquid bottle 1 is connected to the main shell 12 via the intermediate shell 11. The upper outer surface of the silicone main shell 12 has outlet holes 13 evenly distributed around its circumference. The water pump 21 is built into the main shell 12. At the bottom, the outlet of the water pump 21 is connected to the nozzle assembly 4 via the spray pipe 22, and the suction port of the water pump 21 is connected to the suction head 24 via the suction pipe 23. The suction head 24 extends into the liquid bottle 1. The nozzle assembly 4 and the spray hole 13 are positioned correspondingly. The lens assembly 6 is built into the upper part of the main shell 12. The lens assembly 6 collects image information of the detection area in real time. The lens assembly 6, water pump 21, main control module 7, lithium battery pack 8, and function button 9 are electrically connected.

[0058] Reference Figure 5 As shown, the nozzle assembly 4 also includes a converging head 48, the lower end of which is connected to the upper end of the water spray pipe 22, and spray nozzles 49 are evenly installed around the converging head 48.

[0059] In actual operation, the application is inserted into the patient's body. During insertion, the flushing fluid in the liquid bottle 1 is delivered to the converging head 48 by the water pump 21, and finally sprayed out from the spray hole 13 through the spray head 49, thereby flushing the patient's body. At the same time, the patient's body is viewed through the lens assembly 6.

[0060] Example 3, another optional implementation based on the concept of the present invention, discloses a wireless endoscope with a cleaning function. The main structure of the endoscope in this embodiment may include the liquid bottle 1, main shell 12, ejection port 13, water pump 21, nozzle assembly 4, lens assembly 6, main control module 7, lithium battery pack 8, function buttons 9, etc., as in Examples 1 and 2. The feature of this embodiment is its integrated power supply system, control system, and clear human-computer interaction logic.

[0061] In actual use, the user presses and holds the function button for about 2 seconds, and the main control module 7 is powered on and started by the lithium battery pack 8, turning on the device (pressing and holding again will turn it off). After powering on, the main control module 7 immediately drives the lens assembly 6 to start working and enter the video acquisition state. At the same time, it starts the wireless communication module to attempt to pair with an external smart terminal (such as a mobile phone), but keeps the water pump 21 in a standby locked state. At this time, the main control module 7 controls the green LED 127 to flash, and the light is conducted to the outer shell through the light guide column 128, indicating that it is in a waiting pairing state. When the Wi-Fi connection is successfully established and the system voltage is normal, the main control module 7 controls the green LED 127 to turn on and remain on, thereby starting the water pump. It should be noted that if the Wi-Fi pairing is not successful in the power-on state, the water pump can also be started by triggering the function button.

[0062] It should be noted that the signal input of the function button is sent to the main control module 7. When the device is powered on, a short press of the button will unlock and start the water pump. The spraying mode will cycle through the sequence of "weak spray - strong spray - pulse spray - off". "Weak spray" and "strong spray" correspond to different operating power or flow rate of the water pump 21, while "pulse spray" is an intermittent spraying mode. This spraying control logic is executed independently by the main control module 7 and is not directly related to the Wi-Fi pairing status. Even when the wireless pairing is not performed, a short press of the function button will still cause the main control module 7 to respond and control the water pump to work.

[0063] Furthermore, the red LED 126 also transmits light through its dedicated light guide column 128. (The red LED 126, green LED 127, and light guide column 128 together form the indicator light unit 124, as shown below.) Figure 11 , Figure 13 (As shown) When the device is connected to an external power source via the Type-C charging port, the lithium battery enters the charging state, and the main control module 7 controls the red LED126 to flash. When the lithium battery voltage is detected to be too low, the main control module 7 also controls the red LED126 to flash as an alarm.

[0064] Furthermore, the aforementioned red LED 126 and green LED 127 are not directly exposed, but are optically connected to the surface of the outer casing through a light guide post 128. The light guide post 128 is a columnar structure made of optical-grade transparent or semi-transparent material. Its first end is aligned and fixed with the LED beads on the main control module 7 board, and its second end extends to the corresponding viewing window position of the device casing. Its function is to efficiently transmit the light emitted by the LED to the surface of the outer casing to form a clearly visible indicator light spot, while also serving as a structural seal and providing dust and water resistance.

[0065] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
