The present invention can realize spacious in digestive tract putting by the separation sleeve utilizing niti-shaped memorial alloy and macromolecular material and be composited.Can exempt surgical reconstruction digestive tract by this device, and this device is easy to use, effectively can plays the spacious effect of putting of digestive tract.And this device both can take out external as required easily after inserting digestive tract, also can forever insert in body.
Accompanying drawing explanation
Fig. 1 be in digestive tract of the present invention spacious put device use before view.
Fig. 2 be in digestive tract of the present invention spacious put device launch after status architecture schematic diagram.
Fig. 3 be in digestive tract of the present invention spacious put device insert gastrointestinal tract after view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in more detail.
As depicted in figs. 1 and 2, in digestive tract, spacious device of putting mainly comprises the first niti-shaped memorial alloy ring 1, link film 2, second niti-shaped memorial alloy ring 3, involute isolating membrane 4, constrained line 5, guidance spheres 6.Junctional membrane 2 is tubular structure, connects the first niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring 3; Isolating membrane 4 is also tubular structure, and one end is positioned at the side edge with junctional membrane 2 on the second niti-shaped memorial alloy ring 3; One end of constrained line 5 is arranged at the another end of isolating membrane 4; Guidance spheres 6 is connected to the another end of constrained line 5; Development silk 7 is arranged at the medial wall of isolating membrane 4.
As shown in Figure 3, operation principle of the present invention is: in digestive tract, spacious device of putting first infiltrates before use in the aseptic brine ice of 0 DEG C, now the first niti-shaped memorial alloy ring 1, second niti-shaped memorial alloy ring 3 in soft can the flexible state of random variation, can put it in body easily.First niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring 3 are warming up in vivo after more than 35 DEG C and become rigid state, return to original annular, first Ultimum Ti ring 1 is positioned at above the pylorus 9 of stomach 8, second niti-shaped memorial alloy ring 3 is positioned at the below of pylorus 9, link film 2 and be positioned at pylorus 9 place, under duodenum 10 and the wriggling of jejunum 11 and the promotion of alimentary canal content 12, guidance spheres 6 drives isolating membrane 4 by constrained line 5 and is positioned at the development silk 7 on isolating membrane 4 and moves to the end of jejunum 11, until isolating membrane 4 launches completely in jejunum 11, now the first niti-shaped memorial alloy 1 is constrained on above pylorus, therefore the position of this device can be fixed, alimentary canal content 12 is all completely cut off by isolating membrane 4 and jejunum 11 simultaneously, play the spacious object of putting of digestive tract.
