Abstract
An exclusion device in the alimentary canal comprises a first nickel-titanium shape memory alloy ring, a connecting film, a second nickel-titanium shape memory alloy ring, an involute isolating film, a restraint wire and a guide ball. The connecting film is of tubular structure and is connected with the first nickel-titanium shape memory alloy ring and the second nickel-titanium shape memory alloy ring. The isolating film is also of tubular structure, and one end of the isolating film is arranged on the second nickel-titanium shape memory alloy ring and connected with the edge of the connecting film. One end of the restraint wire is arranged at the other end of the isolating film. The guide ball is connected to the other end of the restraint wire. A development wire is arranged in the inner side wall of the isolating film. By means of the nickel-titanium shape memory alloy rings and the isolating film composited by high polymer materials, exclusion in the alimentary canal is realized. By the exclusion device, reconstruction of the alimentary canal in surgical operation can be excluded. Besides, the exclusion device is simple and convenient to use, and effectively excludes the alimentary canal. The exclusion device arranged in the alimentary canal can be either conveniently taken out or permanently arranged in vivo according to needs.

Technical field
The present invention relates to a kind of equipment of medical aspect, be specifically related to the spacious device of putting in a kind of digestive tract.
Background technology
Spacious the putting of digestive tract can be used to treat type 2 diabetes mellitus, obesity, duodenum intractable ulcer etc.Now implement clinically the spacious digestion path that must rebuild by surgical operation food of putting of digestive tract, it performs the operation complicated, large to patient's wound.At present, also not for the spacious medical equipment of putting or device in digestive tract.
Summary of the invention
The deficiency existing in order to overcome above-mentioned prior art, the object of the present invention is to provide the spacious device of putting in a kind of digestive tract, utilizes the separation sleeve that Ultimum Ti and macromolecular material are composited can realize spacious putting in digestive tract.Can exempt surgical operation alimentary reconstruction by this device, this device is easy to use, can effectively play the spacious effect of putting of digestive tract.And this device both can take out externally inserting as required easily after digestive tract, also can forever insert in body.
In order to achieve the above object, the technical solution adopted in the present invention is:
The spacious device of putting in a kind of digestive tract, comprising:
The first niti-shaped memorial alloy ring 1;
The second niti-shaped memorial alloy ring 3, is positioned at the below of the first niti-shaped memorial alloy ring 1;
Isolating membrane 4, is tubular structure, and one end is positioned on the second niti-shaped memorial alloy ring 3 side edge with junctional membrane 2;
The silk 7 that develops, is arranged at the medial wall of isolating membrane 4.
Described junctional membrane 2, isolating membrane 4 and constrained line 5 can be by corrosion resistant nontoxic macromolecular material as preparations such as politef, silica gel, latex, polyethylene, polyurethane.
Described guidance spheres 6 is circle or spindle bead, entirely wraps up or be partly wrapped in isolating membrane 4 far-ends.By can decomposing material preparing as sucrose, starch, flour, PLGA; Also can be processed by magnetic material or paramagnetic material.
Described development silk 7 can be prepared by the material such as tinsel or developing fiber that can develop under soft metal X line.
The first described niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring 2 are soft flexible state that can random variation in the time of 0-30 ℃, return to the rigid state of annular more than 35 ℃ time.According to the spacious difference of device in human body application site of putting in digestive tract, the circle diameter size design of the first niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring can be different.
The length of described junctional membrane 2 and diameter can have different size design according to the spacious device of putting in digestive tract in the difference of human body application site.
The length of described isolating membrane 4 and diameter can have different size design according to the spacious device of putting in digestive tract in the difference of human body application site.
The size of described guidance spheres 6 can have different size design according to the spacious device of putting in digestive tract in the difference of human body application site.
Described the first niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring 3 are tightly wrapped in junctional membrane 2, and isolating membrane 4 and link film 3 are an entirety adding man-hour, connect closely reliable.The far-end of isolating membrane 4 can be wrapped up or partly be wrapped in to described guidance spheres 6 entirely, between guidance spheres 6 and isolating membrane 4, is firmly connected by a bit of constrained line 5.
The present invention can realize spacious putting in digestive tract by the separation sleeve that utilizes niti-shaped memorial alloy and macromolecular material and be composited.Can exempt surgical operation alimentary reconstruction by this device, and this device is easy to use, can effectively plays the spacious effect of putting of digestive tract.And this device both can take out externally inserting as required easily after digestive tract, also can forever insert in body.
Accompanying drawing explanation
Fig. 1 is spacious view of putting before device uses in digestive tract of the present invention.
Fig. 2 is the spacious status architecture schematic diagram of putting after device launches in digestive tract of the present invention.
Fig. 3 is that in digestive tract of the present invention, the spacious device of putting is inserted the view after gastrointestinal tract.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in more detail.
As depicted in figs. 1 and 2, interior spacious isolating membrane 4, constrained line 5, the guidance spheres 6 that device mainly comprises the first niti-shaped memorial alloy ring 1, link film 2, the second niti-shaped memorial alloy ring 3, curls inward of putting of digestive tract.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 on the second niti-shaped memorial alloy ring 3 side edge with junctional membrane 2; One end of constrained line 5 is arranged at the another end of isolating membrane 4; Guidance spheres 6 is connected in the another end of constrained line 5; The silk 7 that develops 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, the spacious device of putting first infiltrates before use in the aseptic brine ice of 0 ℃, now the first niti-shaped memorial alloy ring 1, the second niti-shaped memorial alloy ring 3 are soft flexible state that can random variation, can put it into easily in body.The first niti-shaped memorial alloy ring 1 and the second niti-shaped memorial alloy ring 3 are warming up in vivo 35 ℃ and become rigid state after above, return to original annular, the first Ultimum Ti ring 1 is positioned at pylorus 9 tops of stomach 8, the second niti-shaped memorial alloy ring 3 is positioned at the below of pylorus 9, link 2 of films and be positioned at pylorus 9 places, under the wriggling of duodenum 10 and jejunum 11 and the promotion of alimentary canal content 12, guidance spheres 6 drives isolating membrane 4 by constrained line 5 and the development silk 7 that is positioned on isolating membrane 4 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 pylorus top, therefore can fix the position of this device, alimentary canal content 12 is all isolated with jejunum 11 by isolating membrane 4 simultaneously, play the spacious object of putting of digestive tract.
