DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the gastrointestinal endoscopic polyp removal collector. Figure 2 It is a cross-sectional view of a collecting bottle 101. The utility model provides a gastrointestinal endoscopic polyp removal collector: comprising a collecting bottle 101 and an auxiliary device, wherein a non-slip pad 102 and a discharge valve 103 are provided at the bottom of the collecting bottle 101, wherein the auxiliary device comprises a threaded cap 104, a filter screen 105, a negative pressure tube 106, a piston cylinder 107, a piston 108 and a suction assembly, wherein the suction assembly comprises a sealing sleeve 111 and a matching component, wherein the matching component comprises a connecting tube 112 and a suction device 113. The aforementioned solution can solve the problem that the existing collector cannot effectively separate gastric fluid from polyps during the polyp collection process, and the polyps are immersed in gastric fluid, which affects the pathological evaluation and reduces the accuracy of the pathological evaluation. It can be understood that the aforementioned solution can improve the accuracy of the pathological evaluation.

[0021] In this embodiment, a non-slip pad 102 and a discharge valve 103 are provided at the bottom of the collecting bottle 101. The non-slip pad 102 is fastened to the bottom of the collecting bottle 101 by bolts, and the bolts are countersunk to improve their placement stability. The discharge valve 103 is fixed to the drain port at the bottom of the collecting bottle 101 by bolts to facilitate the discharge of mucus.

[0022] Among them, the threaded cover 104 is threadedly connected to the collecting bottle 101 and is located at the top of the collecting bottle 101, the filter 105 is fixedly connected to the collecting bottle 101 and is located in the collecting bottle 101, the negative pressure tube 106 is threadedly connected to the threaded cover 104 and is located on the threaded cover 104, the piston cylinder 107 is welded to the top of the negative pressure tube 106, the piston 108 is slidably connected to the piston cylinder 107 and is located in the piston cylinder 107, and the suction component is arranged on one side of the threaded cover 104; the threaded cover 104 can be directly mounted on the collecting bottle On the threaded mounting part at the top of the collecting bottle 101, the filter screen 105 is fixed in the stepped cavity in the collecting bottle 101 by precision screws. After installation, the collecting bottle 101 is divided into two upper and lower cavities. The external threaded end at the bottom of the negative pressure tube 106 is directly installed in the threaded mounting hole of the threaded cover 104. A stop valve is provided on the negative pressure tube 106. The piston cylinder 107 is welded to the top of the negative pressure tube 106. The piston 108 is T-shaped and can slide in the piston cylinder 107. A disc is installed on the tail of the piston 108 to facilitate its pulling. The suction assembly is used for suction cooperation.

[0023] The threaded cover 104 has anti-skid semicircular blocks 109, which are arranged at annular intervals on the threaded cover 104. After the anti-skid semicircular blocks 109 are arranged, the threaded cover 104 will form an anti-skid structure when installing or removing, so as to facilitate its stable installation or removal.

[0024] Secondly, the collecting bottle 101 has rectangular anti-skid protrusions 110, which are arranged in an annular manner on the collecting bottle 101. After the rectangular anti-skid protrusions 110 are provided, the collecting bottle 101 forms an anti-skid structure when being installed or removed, which facilitates its stable installation or removal.

[0025] Then, the sealing sleeve 111 is fixedly connected to the threaded cover 104 and positioned on the threaded cover 104; the mating member is disposed on one side of the sealing sleeve 111. The sealing sleeve 111 is fixed to the threaded cover 104 via bolts, with the end of its bottom guide tube extending into the collection bottle 101 and positioned above the filter screen 105, with the mating member performing suction engagement.

[0026] Finally, the connecting tube 112 is sleeved onto the sealing sleeve 111; the suction device 113 is connected to the connecting tube 112 and is located on the side of the connecting tube 112 away from the sealing sleeve 111. One side of the connecting tube 112 is sleeved onto the connecting tube opening at the top of the sealing sleeve 111 and secured with a clamp. The other side of the connecting tube 112 is connected to the suction device 113, which is connected to the endoscope main unit during use.

[0027] When using the present invention to solve the problem that the existing collector cannot effectively separate gastric juice from polyps during the collection of polyps, and the polyps are immersed in gastric juice, which affects the pathological evaluation and reduces the accuracy of the pathological evaluation, the suction device 113 is first connected to the endoscope host, and then the discharge valve 103 is closed, and the piston 108 is pulled to slide in the piston cylinder 107, and the piston 108 is pulled out of the piston cylinder 107, thereby generating negative pressure in the collection bottle 101, and the polyps can be removed by the suction device 113 and the connecting tube 112. The polyps are sucked into the collecting bottle 101. Further, the polyps and water mucus will fall on the filter 105. The water mucus falls below through the filtration holes of the filter 105 and can be discharged by opening the discharge valve 103. The sucked polyps will be directly above the filter 105 to achieve separation, avoiding mucus soaking in the polyps. When taking out the polyps, it is only necessary to unscrew the collecting bottle 101 to take them out, thereby solving the problem that the existing collector cannot effectively separate the gastric juice from the polyps during the polyp collection process, and the polyps are soaked in the gastric juice, which affects the pathological evaluation and reduces the accuracy of the pathological evaluation.

[0028] Example 2:

On the basis of the first embodiment, the utility model provides a gastrointestinal endoscopic polyp removal collector, wherein the auxiliary device further includes a matching tube 201 and an electric negative pressure device 202.

[0030] The mating tube 201 is plugged into the threaded cap 104 and is provided with a shutoff valve. The electric negative pressure device 202 is sleeved onto the side of the mating tube 201 away from the threaded cap 104. One side of the mating tube 201 is plugged into the mating connection port on the threaded cap 104 and is further secured by a clamp. The mating tube 201 is provided with a shutoff valve. When negative pressure is generated by the cooperation of the negative pressure tube 106, the piston cylinder 107, and the piston 108, the shutoff valve is closed. The other side of the mating tube 201 is connected to the electric negative pressure device 202.

[0031] In the embodiment, the negative pressure tube 106, the piston cylinder 107 and the piston 108 cooperate to manually generate negative pressure when the negative pressure is generated, and the equipment can be used in a power failure state. Further, by arranging the cooperation tube 201 and the electric negative pressure device 202, when the power supply is normal, the stop valve on the negative pressure tube 106 is closed, the stop valve on the cooperation tube 201 is opened, and the electric negative pressure device 202 is opened. At this time, the negative pressure structure in the collecting bottle 101 can be automatically formed under the cooperation of the electric negative pressure device 202 and the cooperation tube 201, so that the equipment can be used when the power supply is sufficient, thereby further improving the practical performance of the collector.
