As shown in fig. 1, a polyp collector for gastrointestinal endoscope excision comprises a three-way valve 1 and a recovery bottle 2, wherein three ports of the three-way valve 1 are respectively and fixedly communicated with a liquid inlet pipe 3, a main suction pipe 4 and a branch suction pipe 5; one end of the main suction pipe 4 is communicated with the three-way valve 1, and the other end is provided with a liquid outlet pipe 6; the middle part of the outer wall of the liquid outlet pipe 6 is fixedly communicated with the tail end of the main suction pipe 4; the upper end of the recovery bottle 2 is connected with a cover body 7 through screw threads; the cover body 7 is made of transparent material; the left side of the upper end of the cover body 7 is provided with an inlet pipe 8; one end of the lead-in pipe 8 penetrates through the cover body 7 and is fixed with the cover body 7 in a sealing way, and the other end of the lead-in pipe 8 is communicated with the suction branch pipe 5 through a thread movable joint A9; the lower part of the right side of the recovery bottle 2 is fixedly communicated with a discharge pipe 10; the discharge pipe 10 is communicated with the left end of the liquid outlet pipe 6 through a B thread movable joint 11; the left part of the liquid outlet pipe 6 and the middle part of the discharge pipe 10 are both provided with a cut-off valve 12; a collecting mechanism is arranged in the recovery bottle 2.

As shown in fig. 2-3, the collecting mechanism comprises a spring telescopic rod 13 coaxially fixed at the bottom in the recovery bottle 2; the upper end of the spring telescopic rod 13 is coaxially and rotatably connected with a supporting block 14; a cross-shaped inserting block 15 is fixed at the upper end of the supporting block 14 in a matching way; the upper part in the recovery bottle 2 is sleeved with a bearing block 16 in a matching way; vertical through holes 17 are uniformly formed in the bearing block 16 along the circumferential direction; the bottom in the vertical through hole 17 is fixedly sleeved with a filter screen 18; the upper end of the vertical through hole 17 is correspondingly matched with the lower end of the lead-in pipe 8; a cross-shaped slot 19 is formed in the middle of the lower end of the bearing block 16; the slot 19 is correspondingly inserted with the insert block 15; an action rod 20 is coaxially fixed in the middle of the upper end of the bearing block 16; the action rod 20 passes through the middle part of the cover body 7; a rubber pad 21 is fixed at the upper end in the cover body 7 in a matching way; the action rod 20 passes through the rubber gasket 21 in a sealing mode; the bearing block 16 is made of transparent material; the upper part of the action rod 20 is provided with a mounting through hole 22; an extension rod 23 is inserted into the mounting through hole 22; the lower part of the action rod 20 is provided with a limit through hole 24; the limiting through hole 24 is positioned above the cover body 7; the inner diameter of the limiting through hole 24 is equal to that of the mounting through hole 22.

In the technical scheme, the liquid inlet pipe 3 is communicated with a suction pipe on an external gastrointestinal endoscope host machine, and the liquid outlet pipe 6 is communicated with a negative pressure pipe on an external negative pressure suction machine. When polyps only need to be removed and sampling inspection is not needed, the liquid inlet pipe 3 is controlled to be communicated with the suction main pipe 4 through the three-way valve 1, the block valve 12 on the liquid outlet pipe 6 is closed, and the polyps can pass through the liquid inlet pipe 3, the suction main pipe 4 and the liquid outlet pipe 6 in sequence and are finally sucked into an external negative pressure suction machine; when the polyp needs to be taken out for pathological biopsy, the liquid inlet pipe 3 and the suction branch pipe 5 are controlled to be communicated through the three-way valve 1, the block valve 12 in the middle of the liquid outlet pipe 6 and the discharge pipe 10 is opened, the polyp can sequentially pass through the liquid inlet pipe 3, the suction branch pipe 5 and the introduction pipe 8 at the moment, and finally enters the vertical through hole 17 to be stored, and redundant liquid can flow into the bottom of the recovery bottle 2 and is sucked away through the liquid outlet pipe 6 and the discharge pipe 10 by an external negative pressure suction machine.

In order to collect polyps separately according to the growth part of the polyps, in the technical scheme, when the polyps at different positions are sucked, the expansion rod 23 is inserted into the installation through hole 22 and presses the action rod 20 downwards, the bearing block 16 is pressed downwards to be separated from the introducing pipe 8 under the action of the spring telescopic rod 13 (the cover body 7 and the bearing block 16 are made of transparent materials and are convenient to observe), then the bearing block 16 is rotated, the vertical through hole 17 at the other position is rotated to the position corresponding to the introducing pipe 8, the pressure is relieved, the bearing block 16 moves upwards, and the vertical through hole 17 at the position can be in sleeve connection with the introducing pipe 8. Through the above process, different vertical through holes 17 can be respectively communicated with the introducing tube 8, thereby realizing separate collection of polyps.

After the position of the bearing block 16 is adjusted, the expansion rod 23 needs to be inserted into the limiting through hole 24, at this time, the bearing block 16 cannot move downwards due to the blocking effect of the cover body 7 on the expansion rod 23, the bearing block 16 cannot move upwards due to the blocking effect of the cover body 7 on the bearing block 16, and meanwhile, the rotation of the bearing block 16 is limited (blocked at the position of the introducing pipe 8), so that polyp is prevented from falling out of the vertical through hole 17.

Through the effect of A threaded union 9 and B threaded union 11, recovery bottle 2 can be lifted off (shut off valve 12 on discharge pipe 10), as shown in fig. 2, can be convenient for take out carrier block 16 this moment, and the polyp tissue that holds in vertical through-hole 17 can be taken out and carry out pathological biopsy. The utility model discloses after using, need comprehensive washing and disinfecting so that reuse.
