the front end of the hourglass-shaped telescopic film covering bracket 3 is connected to the front end edge of the outer pipe 1, and the rear end of the hourglass-shaped telescopic film covering bracket 3 is connected to the front end edge of the inner pipe 2; such that the hourglass-shaped telescopic stent graft 3 contracts when the inner tube 2 is moved forward relative to the outer tube 1; when the inner tube 2 is moved backwards relative to the outer tube 1, the hourglass-shaped telescopic stent graft 3 is expanded;
the side part of the front end of the inner tube 2 is provided with more than one first through hole 4, and the side part of the front end of the outer tube 1 is provided with more than one second through hole 5, so that when the hourglass-shaped telescopic covered stent 3 contracts, the axes of the first through holes 4 and the second through holes 5 coincide.
The water supply device can be selected from JW-2 type automatic water supply device manufactured by FUJIFILM corporation, and can control the pumping of clear water into the inner pipe 2 of the box or the pumping of sewage in the inner pipe 2.
The working principle of the intestinal irrigation tube structure is explained as follows: when the intestinal canal flushing pipe is required to spray water into the intestinal canal for flushing, namely, in a first state, the inner pipe 2 moves forwards relative to the appearance, so that the hourglass-shaped telescopic covered stent 3 contracts, the first through hole 4 of the inner pipe 2 is overlapped with and communicated with the axis of the second through hole 5 of the outer pipe 1, clear water is introduced into the inner pipe 2 through the water feeding device, one part of clear water is pressurized and sprayed forwards through the necking of the hourglass-shaped telescopic covered stent 3, and the other part of clear water is sprayed out laterally through the first through hole 4 and the second through hole 5, so that the inner wall of the intestinal canal is flushed laterally, and the inner side of the intestinal canal fold can be flushed fully; when sewage needs to be discharged from the intestinal tract, namely in a second state, the water delivery device is controlled, and the inner pipe 2 pumps the sewage backwards; at this time, the inner tube 2 is controlled to move backwards relative to the outer tube 1, so that the hourglass-shaped telescopic covered stent 3 is opened, and the positions of the first through holes 4 and the second through holes 5 are staggered, so that sewage can only enter the inner tube 2 through the opening in the middle of the hourglass-shaped telescopic covered stent 3.
In the intestinal irrigation tube structure, the front ends of an inner tube 2 and an outer tube 1 are connected through an hourglass-shaped telescopic covered stent 3, the inner tube 2 and the outer tube 1 slide and displace mutually to enable the hourglass-shaped telescopic covered stent 3 to stretch, so that the caliber of the middle part of the hourglass-shaped telescopic covered stent 3 is reduced or increased, the intestinal irrigation tube can meet two major functions of intestinal clear water irrigation and sewage suction, when the clear water irrigation function is realized, the inner tube 2 moves forwards to enable the middle part of the hourglass-shaped telescopic covered stent 3 to shrink, and a first through hole 4 is communicated with a second through hole 5, so that clear water is pressurized to spray water to the side and the front, and the inner side of intestinal plica can be sufficiently irrigated; when realizing sewage suction, move backward through inner tube 2 for flexible tectorial membrane support 3 of hourglass form open, and make first through-hole 4 and second through-hole 5 stagger, make sewage get into inner tube 2 and take out through the flexible tectorial membrane support's of hourglass middle part opening, because flexible tectorial membrane support 3 of hourglass form opens and makes the bore increase, improved the suction efficiency of sewage.
Further, in the intestinal irrigation tube structure, the lateral part of the front end of the inner tube 2 is further provided with more than one third through hole 6, the lateral part of the front end of the outer tube 1 is further provided with more than one fourth through hole 7, and the third through hole 6 and the fourth through hole 7 are inclined holes which are inclined backwards and have the same inclination angle, so that when the hourglass-shaped telescopic covered stent 3 contracts, the axes of the third through hole 6 and the fourth through hole 7 coincide.
