Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] An endoscopic biopsy channel filtering device includes an endoscope 1, an upper connecting end 4 at the upper end of the endoscope 1, a lower connecting end 5 at the lower end of the endoscope 1, a biopsy hole 2 at the upper left part of the endoscope 1, a filter assembly 3 is inserted and connected to the wall of the biopsy hole 2, and the filter assembly 3 is fixedly connected to the endoscope 1.

[0026] In this embodiment, the filter assembly 3 includes a filter frame 31, a fixing ring 32 is fixedly sleeved on the lower part of the outer surface of the filter frame 31, a plurality of positioning screws 33 are interlaced in a ring array at the lower end of the fixing ring 32, a filter ball 34 is interlaced in the lower part of the inner tube wall of the filter frame 31, and the filter frame 31 is interlaced with the biopsy port 2; the filter frame 31 includes a frame body 311, a plurality of No. 1 filter holes 312 are opened at the upper end of the frame body 311, two filter plates 314 are interlaced in the inner tube wall of the frame body 311, a connecting screw groove 313 is opened at the lower part of the inner tube wall of the frame body 311, and the frame body 311 is interlaced with the fixing ring 32; the plurality of positioning screws 33 all pass through the fixing ring 32 and are interlaced with the endoscope 1.

[0027] The above scheme allows for the following: the filter assembly 3 filters the colonoscopy process; the filter frame 31 provides support for the colonoscopy; the fixing ring 32 is inserted and connected to the endoscope 1, and several positioning screws 33 pass through the fixing ring 32 and are inserted and connected to the endoscope 1 to position the filter assembly 3; the connecting screw groove 313 is threaded onto the connecting ring 342 to connect the filter frame 31 and the filter ball 34 together; the filter aperture size on the upper filter plate 314 is smaller than that on the lower filter plate 314 to enhance the filtering effect of the filter assembly 3; the first filter hole 312 and the two filter plates 314 work together to filter the colonoscopy process, improving stability.

[0028] In this embodiment, the filter ball 34 includes a ball 341, a connecting ring 342 is fixedly connected to the middle of the outer surface of the ball 341, the connecting ring 342 has a connecting thread 343 on its outer surface, and a plurality of second filter holes 344 are opened through the outer surface of the ball 341. The connecting ring 342 is inserted and connected to the filter frame 31; the connecting thread 343 is inserted and threadedly connected to the connecting screw groove 313.

[0029] The above solution involves connecting the connecting thread 343 on the connecting ring 342 to the connecting screw groove 313 on the filter frame 31, thereby connecting the filter frame 31 and the filter ball 34 together. The colonoscopy process can be filtered through the ball 341 and several secondary filter holes 344 on the ball 341. The filter ball 34 is easy to connect, install, and disassemble with the filter frame 31, and it is convenient to clean the filter ball 34 and the inside of the filter frame 31.

[0030] It should be noted that this utility model is an endoscopic biopsy channel filtering device. During use, the filter assembly 3 must first be installed onto the endoscope 1. Specifically, the filter frame 31 is inserted and connected to the biopsy channel 2, ensuring the filter frame 31 is in a suitable working position to filter the biopsy channel 2. Simultaneously, the fixing ring 32 is inserted and connected to the endoscope 1. Then, several positioning screws 33 pass through the fixing ring 32 and are inserted and connected to the endoscope 1. The positioning screws 33 utilize their threaded fastening action to precisely position the filter assembly 3, ensuring it is securely installed on the endoscope 1. During colonoscopy, it will not loosen or shift due to equipment operation or movement. In addition, this connection method via the positioning screw 33 makes the connection, installation, and disassembly of the filter assembly 3 and the endoscope 1 convenient. When cleaning, maintenance, or replacement of the filter assembly 3 is required, it can be easily disassembled by simply unscrewing the positioning screw 33. This convenient operation provides convenience for subsequent equipment management. Next, the connecting screw groove 313 and the connecting ring 342 are threaded together. Through this threaded connection, the filter frame 31 and the filter ball 34 are connected together to form a complete filter structure. Similarly, this threaded connection between the filter ball 34 and the filter frame 31 also features convenient installation and disassembly, facilitating the internal cleaning of the filter ball 34 and the filter frame 31 after a period of use. Cleaning removes accumulated impurities to ensure optimal filtration performance and extend service life. This ensures the entire filter assembly 3 continues to function effectively. During colonoscopy, when material passes through the endoscopic biopsy channel, it first passes through the filter ball 34. The filter ball 34, with its structure and material properties, performs initial filtration, intercepting and blocking larger particles and foreign objects, thus purifying the material passing through the biopsy channel and reducing the pressure on subsequent filtration. It also prevents larger impurities from directly entering the internal structure, preventing blockages and other adverse effects on the biopsy channel. After initial filtration by the filter ball 34, the material then enters the filter frame 31 for further filtration. The filter frame 31 is equipped with two filter plates 314 and several first-order filter holes 312. These filtration structures further filter the material. The filter plates 314 can further intercept some irregularly shaped and slightly larger residual impurities, while the first-order filter holes 312 can precisely filter out some smaller particles of impurities according to their set pore size. Through this layer-by-layer filtration method, the filtration accuracy of the material is further improved, significantly enhancing the filtration effect of the filter assembly 3, and preventing impurities from entering the endoscopic biopsy channel to the greatest extent. This effectively avoids blockage of the endoscopic biopsy channel due to impurity accumulation during use, ensuring that colonoscopy can be performed smoothly and continuously, and improving the accuracy and reliability of the examination. In summary...This endoscopic biopsy channel filtering device, through its rational structural design and tight coordination of components, achieves convenient installation and disassembly as well as highly efficient filtration. It ensures that the filtering components themselves are easy to clean and maintain, while effectively enhancing the filtration effect on the endoscopic biopsy channel, preventing blockages, and providing strong support for endoscopic examinations.
