Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the attached drawings 1-2, a polyp collector for gastrointestinal endoscope excision comprises a transparent tube 1, wherein two ends of the transparent tube 1 are respectively connected with an absorption cover 2 and a negative pressure device 3; the improved vacuum cleaner is characterized in that a collecting device 16 is connected and arranged between the absorption cover 2 and the negative pressure device 3 through the transparent pipe 1, the collecting device 16 comprises an inner pipe 4, a plurality of collecting pipes 5 are connected and arranged in the inner pipe 4, filter screens 6 matched with the transparent pipe 1 are arranged in the collecting pipes 5, an outer pipe 7 is rotatably connected and arranged outside the inner pipe 4, the outer wall of the inner pipe 4 is matched with the inner wall of the outer pipe 7, the bottom of the inner pipe 4 is connected with the inner bottom wall of the outer pipe 7 through a spring 8, and a handle 9 extending out of the outer pipe 7 is downwards arranged at the.
