Abstract
The utility model relates to a stopper implanted to the inner cavity of the human tract, which comprises a support bracket and a sealed tube composed of a diaphragm valve or a diaphragm, wherein one side of the sealed tube provided with a liberation part is connected with the inner surface of a fixed part of the support bracket. The utility model has the characteristics of simple structure, convenient operation, safe and reliable application, simultaneous satisfaction of the physical and the chemical lung volume reduction, and recycle of the sealed tube without time limitation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically relates to a kind of stopper that is used to be implanted in the body cavities.
Background technology
The surgery lung volume reducing operation has experienced the clinical research in nearly ten years, affirming that it is to when improving emphysema patient respiratory function in late period, people also recognize gradually because the body constitution of this class patient own is relatively poor, and that the surgery lung subtracts the wound of appearance is big, postoperative death rate and complication height make most patients can not tolerate this type of operation.For this reason, people begin to develop the lung volume reducing operation of invasive.The bronchoscope lung volume reducing operation is an emophysematous new technique of treatment that is in conceptual phase that has just risen the America and Europe in recent years.
The target that Wicresoft's lung subtracts appearance is to reach the lung volume reducing by Wicresoft's mode that non-surgery operation excises, and can not cause patient's obvious damage, or can tolerate under the prerequisite the patient, subtracts to hold by lung and improves patient's respiratory function.Wicresoft's lung volume reducing operation mainly contains two kinds at present: the one, physical property, be implanted into the block plug of being with one-way cock at bronchial lumen, make the gas only export but no import of this lung section, reach the purpose that causes lung to subtract appearance.Existing multiple at present patent about the bronchus blocking valve, as United States Patent (USP): US6174323, US6527761, US6709401 etc., these patents mostly are permanent implantation, no longer can take out after the implantation.Another kind is a chemical, makes alveolar and bronchus obturation reach lung by the perfusion chemicals and subtracts appearance, as U.S. Pat 6682520.But these inventions all can not be carried out physical property and chemical lung simultaneously and subtract the appearance treatment.
Sometimes need clinically with by inaccessible air flue from newly open-minded, as when the treatment Bronchio-pleural fistula, after fistula mouth closure, take out occluder and can make lung tissue that the part obturation do not open from new restore funcitons.Though at present callable bronchus blocking valve is arranged, the actual recovered rate is not high, along with the prolongation of the time of implantation, implant is wrapped up by bronchial mucosa, makes recovery more and more difficult.Very need be able to satisfy physical property and chemical clinically simultaneously and subtract the recuperable occluder that holds and be not subjected to time restriction.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, and is easy to operate, safe and reliable, can satisfy physical property simultaneously and chemical subtracts appearance, and be not subjected to time restriction can reclaim sealed tube be used to be implanted in stopper in the body cavities.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of stopper that is used in the implant into body tube chamber road, comprise support and the sealed tube that is made of diaphragm valve or diaphragm, the sealed tube one side with free fraction links to each other with the inner surface of support standing part.
This utility model adopts technique scheme, because distolateral being fixedly connected on the distolateral interior table of support one of sealed tube, can make alveolar and sealed tube obturation reach the effect that lung subtracts appearance by the perfusion chemicals, also can make the gas only export but no import of lung section reach the purpose that lung subtracts appearance simultaneously, so stopper of the present utility model can satisfy physical property and chemical subtracts the appearance effect by sealed tube.Only some is connected with support this utility model owing to sealed tube in addition, and major part is free fraction and support disengaging, though tracheal mucosa coated stent, but because of sealed tube not exclusively is connected on the support, therefore can realize reclaiming can not causing sealed tube tearing of local organization, and not be subjected to time restriction, easy to operate, safe and reliable.

Below in conjunction with drawings and Examples this utility model embodiment is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is an another kind of structural representation of the present utility model.

The specific embodiment
See the stopper that is used in the implant into body tube chamber road shown in Figure 1, comprise support 1 and by the sealed tube 2 that diaphragm valve or diaphragm constitute, the sealed tube 2 with free fraction 2-1 links to each other with the inner surface of support 1 standing part 1-1.The two ends of seeing Fig. 1,2 described these supports 1 are horn mouth and outside turnup, support 1 is made of the two-stage nitration reduced diameter portion at least, by turnup end face outside support 1 two ends, or the outer surface of support 1 has anti-skidding barb 1-2 shown in Fig. 3,4, with the frictional resistance of increase, prevent support 1 moving in tract effectively with tract.Support 1 of the present utility model is made the support of self-inflated or inflation by metal or nonmetallic materials, and can be made by biodegradable or nondegradable material.Support 1 of the present utility model is seen shown in Figure 1, and one of the inner surface of its standing part 1-1 and sealed tube 2 distolaterally links to each other by binding agent, and sealed tube 2 is placed in the support; One of the inner surface of support 1 standing part 1-1 and sealed tube 2 distolaterally can also be linked to each other by suture, sealed tube 2 is placed in the support 1, perhaps the inner surface of support 1 standing part 1-1 is bonding with sealed tube 2 one ends or sew up and to link to each other, and turns in the sealed tube 2 and be placed in the support 1.
Sealed tube 2 of the present utility model is the medical polymer biological film, as film of silica gel, latex, various animals etc., or sealed tube 2 is made by biodegradable or nondegradable material, the free fraction 2-1 of sealed tube 2 is duckbill or taper, and its end has opening 2-2, and this opening 2-2 is aperture or otch; The free fraction 2-1 of sealed tube 2 of the present utility model is duckbill or taper, but its end sealing.
