Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a modular electronic endoscope. Background Technology

[0002] A modular electronic endoscope is a medical device used to examine internal organs of the human body. It consists of multiple modules combined together. During examination, a probe is inserted into the body, a camera captures images of the internal situation, and the images are transmitted to a display screen. Modular electronic endoscopes can examine the condition of internal organs, helping doctors to detect diseases and problems.

[0003] A search of Chinese utility model patent (publication number CN221469821U) reveals a modular electronic endoscope. By using a drive shaft inside the probe and a drive motor inside the connector, the modular electronic endoscope can be easily cleaned by a rotating cleaning plate when it is obstructed, thus improving the effectiveness of the modular electronic endoscope.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks:

[0005] When the cleaning plate in this solution rotates inside human tissue, it is easy to scratch the tissue. Furthermore, the scraper is easily squeezed by the tissue and may come into contact with the camera, potentially scratching the camera during rotation. Utility Model Content

[0006] This utility model aims to provide a modular electronic endoscope to solve the problems mentioned in the background art. This solution cleans foreign objects that are obstructing the camera by rotating the rotating block and pushing the ejector block. The surface of the rotating block is flat, and its rotation will not cause damage to human tissue, ensuring the safety of the cleaning process. Moreover, during the cleaning process, neither the rotating block nor the foreign object to be cleaned will rub against the camera, which can effectively protect the camera lens, prevent the lens from being scratched, and extend the service life of the camera.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A modular electronic endoscope includes a probe rod. An illumination lamp and a camera are fixedly connected to the inner end of the probe rod, respectively. Cables are connected to the outer ends of both the illumination lamp and the camera. A rotating block, matching the shape of the inner cavity, is rotatably connected to the inner wall of the probe rod. Multiple through holes are formed on the rotating block, each corresponding to a position of the illumination lamp and the camera. An electric actuator and a servo motor are installed at the inner end of the probe rod. A limit post is fixedly connected to the end of the rotating block closest to the inner cavity of the probe rod. The output end of the servo motor is connected to the limit post. A connecting rod is provided within the inner cavity of the probe rod. The output end of the electric actuator is connected to the connecting rod. Multiple ejector blocks are fixedly connected to the end of the connecting rod furthest from the electric actuator. The ejector blocks are positioned between adjacent illumination lamps and cameras, and their shapes match the through holes.

[0009] Preferably, the plurality of through holes are arranged in a ring at equal intervals.

[0010] Preferably, the limiting post is configured as a bent structure, and one end of the limiting post is fixedly connected to the edge of the rotating block, while the other end of the limiting post is coaxially arranged with the through hole.

[0011] Preferably, a mounting ring is fixedly connected to one end of the probe rod near the rotating block, and multiple baffles are fixedly connected to the inner end of the mounting ring, with the multiple baffles arranged in a ring at equal intervals.

[0012] Preferably, the baffle abuts against the outer surface of the rotating block.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] This solution removes foreign objects obstructing the camera by rotating a block and pushing out an ejector block. The surface of the rotating block is flat, and its rotation will not cause harm to human tissue, ensuring the safety of the cleaning process. Furthermore, during the cleaning process, neither the rotating block nor the foreign object to be cleaned will rub against the camera, effectively protecting the camera lens, preventing it from being scratched, and extending the camera's lifespan.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] like Figure 1-5 The modular electronic endoscope shown includes a probe rod 1. An illumination lamp 11 and a camera 2 are fixedly connected to the inner end of the probe rod 1. Cables 3 are connected to the outer ends of the illumination lamp 11 and the camera 2. A rotating block 4, matching the shape of the inner cavity, is rotatably connected to the inner wall of the probe rod 1. Multiple through holes 5 are opened on the rotating block 4, and the positions of the multiple through holes 5 correspond one-to-one with the positions of the illumination lamp 11 and the camera 2. An electric push rod and a servo motor are installed on the inner end of the probe rod 1. A limit post 6 is fixedly connected to the end of the rotating block 4 near the inner cavity of the probe rod 1. The output end of the servo motor is connected to the limit post 6. A connecting rod 8 is provided in the inner cavity of the probe rod 1. The output end of the electric push rod is connected to the connecting rod 8. Multiple ejector blocks 7 are fixedly connected to the end of the connecting rod 8 away from the electric push rod. The ejector blocks 7 are located between adjacent illumination lamps 11 and cameras 2, and the shape of the ejector blocks 7 matches the through holes 5. The multiple through holes 5 are arranged in a ring at equal intervals.

[0023] A modular electronic endoscope is a medical device used to examine internal organs. It consists of multiple modules combined together. During examination, the probe is inserted into the body, and a camera captures images of the internal situation, which are then transmitted to a display screen. The modular electronic endoscope can examine the condition of internal organs, helping doctors to detect diseases and problems. However, the camera is easily obstructed by fluid or other tissues inside the body during actual use. Therefore, the modular electronic endoscope needs to be removed before the camera surface can be cleaned.

[0024] In this design, camera 2 and lighting lamp 11 are connected to multiple through holes 5, allowing camera 2 to take pictures through the through holes 5 and lighting lamp 11 to emit light through the through holes 5. Both camera 2 and lighting lamp 11 are connected to the endoscope host via cables 3, enabling power supply and image transmission. When the inside of the through holes 5 is blocked by tissue or other foreign objects, it will affect the normal shooting of camera 2. At this time, the user can start the servo motor to drive the limit post 6 to rotate, which in turn drives the rotating block 4 to rotate, causing the multiple through holes 5 to disengage from camera 2 and lighting lamp 11 and move to the adjacent positions of camera 2 and lighting lamp 11. The through holes 5 are at the same horizontal position as the multiple ejector blocks 7. The user activates the electric push rod to move the connecting rod 8, which in turn moves the multiple ejector blocks 7. The multiple ejector blocks 7 can be inserted into the multiple through holes 5 respectively, thereby pushing out the foreign objects in the through holes 5. Then the electric push rod and the servo motor are reset in succession, so that the camera 2 and the lighting lamp 11 can get a good field of view again. The surface of the rotating block 4 is flat, and its rotation will not cause damage to human tissue, so the cleaning process can be guaranteed to be safe. During the cleaning process, the rotating block 4 and the foreign objects to be cleaned will not rub against the camera 2, which can effectively protect the lens of the camera 2.

[0025] The limiting post 6 is configured as a bent structure, and one end of the limiting post 6 is fixedly connected to the edge of the rotating block 4, while the other end of the limiting post 6 is coaxially set with the through hole 5.

[0026] In this design, the limiting post 6 is configured as a bent structure, with one end fixedly connected to the edge of the rotating block 4. This effectively prevents the limiting post 6 from interfering with the positions of the camera 2, cable 3, and ejector block 7 during rotation. The other end is coaxially set with the through hole 5, which ensures that the servo motor can smoothly drive the rotating block 4 to rotate through the limiting post 6.

[0027] A mounting ring 9 is fixedly connected to one end of the probe rod 1 near the rotating block 4. Multiple baffles 10 are fixedly connected to the inner end of the mounting ring 9. The multiple baffles 10 are arranged in a ring at equal intervals and abut against the outer surface of the rotating block 4.

[0028] In this solution, the multiple baffles 10 can isolate the rotating block 4 from the human tissue, thereby further reducing the damage that the rotation of the rotating block 4 may cause to the tissue. At the same time, when the multiple ejection blocks 7 push the foreign object out of the through hole 5, the foreign object may still remain on the outside of the through hole 5. At this time, through the setting of multiple baffles 10, when the rotating block 4 is reset, the foreign object left on the outside of the through hole 5 will be intercepted by the baffles 10, causing it to leave the outside of the through hole 5, thereby ensuring that the foreign object is cleaned up.

[0029] The specific implementation process is as follows:

[0030] In use, the user inserts the probe 1 into the human tissue. The camera 2 takes pictures of the tissue through the through hole 5, and the light from the lamp 11 shines out through the through hole 5 to provide illumination. When the inside of the through hole 5 is blocked by tissue or other foreign objects, the user starts the servo motor to drive the limit post 6 to rotate, which in turn drives the rotating block 4 to rotate, so that multiple through holes 5 are separated from the camera 2 and the lamp 11 respectively, and move between the adjacent camera 2 and the lamp 11. At this time, multiple through holes 5 are at the same horizontal position as multiple ejector blocks 7. The user starts the electric push rod to push the connecting rod 8 to move, so that the connecting rod 8 drives multiple ejector blocks 7 to move. Multiple ejector blocks 7 are inserted into multiple through holes 5 respectively, thereby pushing out the foreign objects in the through holes 5. Then the user controls the electric push rod and the servo motor to reset in succession, so that the ejector blocks 7 and the rotating block 4 are reset in succession. During the reset process of the rotating block 4, the foreign objects that were just pushed out of the outside of the through hole 5 are intercepted by the baffle 10, so that they are removed from the outside of the through hole 5, thereby allowing the camera 2 and the lamp 11 to get a good field of view again.
