Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, specifically to an endoscope with a lens that is easy to clean. Background Technology

[0002] An endoscope is inserted into the body through natural openings or a small surgical incision. An endoscope consists of a flexible part, a light source, and a set of lenses. During use, the endoscope is guided into the organ to be examined, allowing direct visualization of changes in the relevant area.

[0003] After an endoscope is inserted into the body, blood or other tissues from the body can adhere to the lens, causing it to become blurry and affecting the imaging results. Currently, the problem is solved by installing a nozzle near the lens and facing it directly, using water to rinse the lens and keep it clean and free of foreign objects. However, this solution has its drawbacks. The water sprayed from the nozzle to rinse the lens remains in the patient's body and can only be excreted through the patient's metabolism, thus limiting the number of times the lens can be cleaned. In addition, the presence of a large amount of water in the patient's body after the procedure may cause discomfort.

[0004] A patent application with application number CN202021203861.7 was also found, disclosing an endoscope with an easy-to-clean lens, including an imaging component, a bending component, and an operating component. The imaging component includes a guide head, a lens, two control mechanisms, and a cleaning mechanism. A cleaning groove is provided on one side of the guide head. The lens is mounted on the guide head, and the lens surface is located in the cleaning groove. The two control mechanisms are symmetrically arranged about the lens. Each control mechanism includes a baffle, a slider, and a control water pipe. Each baffle faces the cleaning groove and is connected to the slider. Each slider is slidably connected to a groove provided on the guide head. The water outlet of each control water pipe is connected to the groove. The water inlet and outlet of the cleaning mechanism are both connected to the cleaning groove.

[0005] While the aforementioned patent does solve the technical problem of water entering the human body and being unable to drain in the prior art, the guide head of the lens of a general endoscope is a cylindrical structure, while the aforementioned patent has a cuboid structure. This structure has sharp edges after entering the human body, which may touch the human body and cause discomfort. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems by providing an endoscope with a lens that is easy to clean.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] An endoscope for easy lens cleaning includes an endoscope body, a guide head mounted on one side of the endoscope body, and a lens mounted inside the guide head.

[0009] A cleaning structure with a cleaning lens is installed on the outside of the guide head;

[0010] The cleaning structure includes a limiting block, within which multiple sets of movable and adjustable baffles are installed, and multiple sets of cleaning ports are opened at the lower end of the baffles.

[0011] Preferably, the guide head has a groove for mounting the lens.

[0012] Preferably, a water outlet annular groove is formed inside the guide head and outside the groove, and a connecting hole is formed between the water outlet annular groove and the groove.

[0013] Preferably, the guide head has a water outlet pipe that connects to the water outlet annular groove.

[0014] Preferably, the limiting block is equipped with multiple sets of blocks that move in conjunction with the baffle, and a moving area for the baffle to move is formed between two of the blocks. A return spring is installed between the block and the inner wall of the moving area.

[0015] Preferably, the guide head has a water inlet pipe that connects to the moving area.

[0016] Preferably, the baffle has a triangular structure, and multiple baffles are arranged in an array around the central axis of the guide head.

[0017] Preferably, a water inlet is provided in the baffle and the water inlet is connected to a cleaning port, the cleaning port being tilted at 45° towards the lens.

[0018] With the above structure, this utility model has the following advantages:

[0019] This invention uses a system where cleaning water enters the inlet pipe, causing baffles in the moving area to move. This movement triggers a return spring, and multiple baffles work in conjunction with the lens within a groove, placing the lens in a sealed cavity for cleaning. The cleaning water, after cleaning, remains in the groove and then flows through a connecting hole into an outlet ring groove, which is then discharged through the outlet pipe. After cleaning, the water pressure in the inlet pipe disappears, and the return spring resets the baffles. The lens is separated from the human body by the baffles, preventing cleaning water from entering the body and allowing it to drain. This design is also suitable for guide heads with cylindrical structures.

[0020] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The present invention will now be described in further detail in conjunction with the full text.

[0030] Combined with appendix Figures 1-4An endoscope for easy lens cleaning includes an endoscope body 1, a guide head 2 installed on one side of the endoscope body 1, a lens 10 installed inside the guide head 2, and a cleaning structure 3 for cleaning the lens 10 installed on the outside of the guide head 2. The baffle 302 and groove 4 of the cleaning structure 3 place the lens 10 in a sealed cavity, allowing the lens 10 to be cleaned and the water to be drained, thereby solving the problem mentioned in the background art of water entering the human body and not being able to drain. As for how to achieve the above functions, a more detailed explanation will be given below.

[0031] Specifically, the cleaning structure 3 includes a limiting block 301, in which multiple sets of movable and adjustable baffles 302 are installed, and multiple sets of cleaning ports 303 are opened at the lower end of the baffles 302.

[0032] In specific implementation of this utility model, such as Figures 2-4 The guide head 2 shown has a cleaning structure 3 for a cleaning lens 10 installed on its outer side. Multiple sets of stop blocks 304 that move in conjunction with the baffle 302 are installed in the limiting block 301. A moving area that moves in conjunction with the baffle 302 is formed between two stop blocks 304. A return spring 305 is installed between the stop block 304 and the inner wall of the moving area. A water outlet pipe 7 that connects to the water outlet annular groove 5 is opened in the guide head 2. A water inlet pipe 8 that connects to the moving area is opened in the guide head 2. The water inlet pipe 8 is connected to an external water pump. Water enters through the water inlet pipe 8, pushing the baffle 302 to move within the moving area between the two stops 304. The return spring 305 extends, and then the cleaning water enters the water inlet 9. It is then sprayed onto the lens 10 in the groove 4 through the cleaning port 303 to complete the cleaning. During cleaning, due to the water pressure, multiple sets of baffles 302 merge into a circle, thereby sealing the upper end of the groove 4 and forming a cleaning chamber. Specifically, the water inlet 9 is much smaller than the moving area. From the large aperture to the small aperture of the water inlet 9, although the water pressure can enter the water inlet 9, it will also push multiple sets of baffles 302 to move closer to each other. Furthermore, the diameter of the cleaning port 303 is smaller than the diameter of the water inlet 9.

[0033] Specifically, the water inlet pipe 8 is connected to external clean water, and the clean water can be driven into the water inlet pipe 8 by a small pump (not shown in the figure), or other small water flow and high pressure driving components can be used.

[0034] In this invention, the baffle 302 has a triangular structure, and multiple baffles 302 are arrayed around the central axis of the guide head 2. The multiple sets of baffles 302 move and cooperate with the lens 10 in the groove 4, placing the lens 10 in a sealed cavity for cleaning and draining the water. This solves the problem of existing patents having cuboid structures that create sharp edges that could cause discomfort to the human body. The outer side of the baffle 302 has a rubber layer. When multiple sets of baffles 302 move closer together due to water pressure, they form a circle, blocking the lens 10 and creating a cavity. The gaps between the multiple sets of baffles 302 are sealed by the rubber layer. A water inlet 9 is provided inside the baffle 302 and connects to a cleaning port 303. The cleaning port 303 is tilted at 45° towards the lens 10, creating an impact at an angle that cleans the lens 10 with the cleaning water.

[0035] A groove 4 is formed inside the guide head 2 to accommodate the lens 10. A water outlet annular groove 5 is formed inside the guide head 2 and outside the groove 4. A connecting hole 6 is formed between the water outlet annular groove 5 and the groove 4. After cleaning, the cleaning water remains in the groove 4, then enters the water outlet annular groove 5 through the connecting hole 6, and is discharged through the water outlet pipe 7 connected to the water outlet annular groove 5. Excess cleaning water in the groove 4 will flow out, but the amount of water is very small and does not affect the function to be achieved in this embodiment.

[0036] The working principle of this utility model:

[0037] Cleaning water enters the inlet pipe 8 and then the moving area, pushing the baffle 302 within the moving area to move. The return spring extends, and multiple sets of baffles 302 move, cooperating with the lens 10 in the groove 4, so that the lens 10 is located in a sealed cavity, and then the lens 10 is cleaned. The water enters the inlet 9 and is sprayed onto the lens 10 in the groove 4 through the cleaning port 303, completing the cleaning. During the cleaning process, due to the water pressure, multiple sets of baffles 302 merge into a circle, thereby sealing the upper end of the groove 4 and forming a cleaning chamber. After cleaning, the cleaning water remains in the groove 4 and then enters the outlet ring groove 5 through the connecting hole 6. It is then discharged through the outlet pipe 7 connected to the outlet ring groove 5. After cleaning is completed, the water pressure in the inlet pipe 8 disappears, and the return spring drives the baffle 302 to return to its original position.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
