the two air pipes are positioned in the inner wall of the perfusion pipe, and one ends of the two air pipes are respectively communicated with the inner cavities of the two expansion pipes;

the openings of the two direction-adjusting barrels are opposite, the pistons are sleeved in the direction-adjusting barrels in a sliding mode, and two ends of the movable pipe are fixedly connected with the two pistons respectively; the two direction-adjusting barrels are fixedly connected with the outer peripheral wall of the perfusion tube;

the free ends of the two air pipes are respectively communicated with the two direction-adjusting barrels.

Furthermore, two ends of the connecting rod are respectively and fixedly connected with two direction-adjusting barrels.

Furthermore, one end of the push plate is fixedly connected with the outer wall of the movable pipe.

Furthermore, all install the stagnant water clamp on the pipeline of lateral pipe.

Furthermore, a flow regulator is arranged on the pipeline of the perfusion tube.

The beneficial effects of the utility model are that:

because the opposite two sides of the perfusion tube are provided with the grooves, the foldable expansion and contraction tube is positioned in the grooves; the air pipe respectively communicates the two direction-adjusting barrels with the two expansion pipes; two ends of the movable tube are respectively fixedly connected with the two pistons; one expansion and contraction pipe is extended and the other expansion and contraction pipe is folded by moving the movable pipe up and down; the steering effect of the perfusion tube is realized.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1 to 5, a Y-shaped steering perfusion tube for endoscopic surgery comprises a perfusion tube 10, a direction-adjusting barrel 20, a piston 30, a movable tube 40, a telescopic tube 130, an inner folding semicircular tube 131 and an outer folding semicircular tube 132;

the infusion tube 10 is provided with two communicated branch tubes 11, one end of each branch tube 11, which is far away from the infusion tube 10, is fixedly provided with a needle 111, and the needle 111 is used for penetrating through a rubber stopper of an infusion bottle; the end of the filling pipe 10 remote from the branch pipe 11 is provided with a liquid outlet (not shown in the figure).
