As shown in fig. 1, the utility model provides an attraction connector, it sets up drainage tube 2 on being responsible for 1 including being responsible for 1 and slope, is responsible for 1 and drainage tube 2 intercommunication, is responsible for 1 and has entrance point 11 and exit end 12, and the exit end 12 of being responsible for 1 is inside to be equipped with the installation position that a plurality of is used for cup jointing not unidimensional sheath pipe.

Based on the technical scheme, the outlet end 12 of the main pipe 1 is provided with the plurality of installation positions, so that the main pipe 1 of the suction connector can be sleeved with sheath pipes with different sizes. The suction connector is matched with a sheath tube with one specification for use at a time. In inspection or operation, when the sheath pipe of different specifications need to be used, medical staff no longer need to change different suction connectors, only need the utility model provides a suction connector's exit end 12 connect corresponding specification size the sheath pipe can to medical staff's effective work efficiency has been improved. When the suction connector is used, the choledochoscope enters from the inlet end 11 of the suction connector and penetrates through the suction connector to be inserted into the sheath tube, and the drainage tube 2 is externally connected with the negative pressure suction tube, so that foreign matters such as liquid, calculi and the like in the suction connector flow out of the drainage tube 2. The suction connector can give consideration to the operation of the choledochoscope and the suction and drainage of the sheath tube, thereby achieving the best treatment effect. In this embodiment, the suction connector is a medical plastic tube, which has a smooth surface, good biocompatibility, easy cleaning and disinfection, high strength and difficult deformation.

Specifically, the main pipe 1 includes a first section and a second section, a first end of the first section is communicated with a first end of the second section, a second end of the first section is an outlet end 12, a second end of the second section is an inlet end 11, and an inner diameter of the first section of the main pipe 1 is gradually increased from a middle portion thereof to the outlet end 12 to form a plurality of installation positions. A plurality of installation positions in the first section can adapt to the size of sheath pipes with different specifications. When the sheath with the smaller diameter needs to be sleeved, the sheath can be extended into the middle part of the first section, and when the sheath with the larger diameter is sleeved, the sheath is extended to the 12 ports of the outlet end. In this embodiment, the inner diameter of the outlet end 12 of the main tube 1 is 8mm, and the inner diameter of the middle portion of the first section is 5.5mm, so that the main tube 1 can be sleeved with sheath tubes with the specification of 14F-22F (i.e. the diameter of 4.46 mm-7 mm). Wherein the middle of the first section of the main pipe 1 is located at 1/3 of the total length of the main pipe 1, ensuring that enough space is left in the main pipe 1 to form different mounting positions. The annular bulge 3 is nested in the first section of the main pipe 1, the height of the annular bulge 3 is gradually reduced from the middle part of the first section to the two ends of the first section respectively to form a bulge with an arc-shaped cross section, and the surface of the annular bulge 3 is smooth, so that the situation that the sheath pipe is scratched due to the fact that the shape is too sharp can be avoided.
