Abstract
The utility model relates to an esophagus inner support with a backflow prevention membrane skirt. The membrane skirt which has a smaller upper opening and a bigger lower opening is suck on a cavity membrane on the lower end of the support. When food is conveyed to the membrane skirt, the membrane skirt opens under the action of food. When food is not conveyed to the membrane skirt, the membrane skirt is under the state of close. Thereby, the backflow of food can be effectively prevented. The utility model can improve the quality of life of the patients which have oesophagus cancer and cardia cancer. The utility model is a novel oesophagus inner support for prolonging the survival time of the patients.
Description
This utility model relates to medical product, particularly a kind ofly is used to expand esophagus and can prevent the stent in esophagus structure that food backflows.
The present inner support that is used for various esophagectasiss both at home and abroad has multiple, and the corkscrew esophagus support that useful memorial alloy is made has double horn mouth spiral stent in esophagus (Chinese patent 95239287.9).
A kind of recoverable band film Esophageal Stent and retracting device thereof that Chinese patent 95241221.x provides, it is a kind of advanced Esophageal Stent of generally acknowledging at present, its film can prevent effectively that esophageal cancer cell from stopping up esophagus to the rack inner wall growth, improve the life quality of patient with esophageal carcinoma, prolonged survival time of patients.But this support is defectiveness also, can not prevent well that promptly food from backflowing, and in a large amount of cardia, esophagus, hypomere operator ubiquity food in various degree after losing cardia effect phenomenon of backflowing, cause the patient to form reflux esophagitis, cause new misery to the patient, even produce aspiration pneumonitis thus and threat to life.
The purpose of this utility model is: design a kind of stent in esophagus of bringing the stream film back to, allow the film that backflows have the effect of one-way cock, it can guarantee to take food unobstructed, prevents that food from backflowing, and what overcome that existing Esophageal Stent exists can not prevent the defective that food backflows.
The purpose of this utility model is achieved in that the hypomere inner chamber at band film recoverable Esophageal Stent, paste a circle and the identical medical grade silicon rubber film skirt of support hypomere inner chamber, the natural extension on the feed time of film skirt, allow food go into stomach, after stopping feed, the film skirt is to press close to closed form, film skirt inwall is attached together, can effectively prevent backflowing into stomach food, when the patient vomits because of the improper generation of taking food, the big pressure of gastric can make that the skirt film is reverse to be opened, the food debris that spues, drinking-water or when taking food once more under the drive of water or food the film skirt can restore to the original state.
Fig. 1 is this utility model sketch map
Fig. 2 is a film skirt sketch map
Among the figure: 1 stainless steel silk skeleton, 2 medical grade silicon rubber films, 3 reclaim nylon wire, 4 anti-displacement agnails, thin film shirt rim, 5 support lower end, 6 anti-refulx membrane skirts, 7 bonding limits
Further introduce technology contents of the present utility model and implementation method below in conjunction with accompanying drawing:
Be provided with recovery nylon wire 3 in the upper end of stainless skeleton 1, there is anti-displacement agnail 4 in the stage casing, inside and outside skeleton 1, be compounded with medical grade silicon rubber film 2, form a bell mouth shape thin film shirt rim 5 in the support lower end, 5 inner chamber is provided with the bigger anti-refulx membrane skirt 6 of suitable for reading smaller end opening that a usefulness medical grade rubber film is made in the shirt rim, form a bonding limit 7 after the suitable for reading and rack bore bottom strong bond of film skirt 6, bonding limit 7 forms one with the rack bore smooth excessiveness.The film skirt is attached together as the balloon rubber membrane inwall of unaerated, can open under the effect of food.
The utility model has following advantage and effect: can prevent effectively that oesophagus from inserting support Patient's rear food reflux of taking food.
Can be widely used in: after 1. cardia cancer, Operation on Esophageal Cancer excision, oesophagus, stomach coincide Narrow or recurrence does not have again surgical indication needs the implant frame person;
2. severe reflux esophagitis patient
3. carcinoma of gastric cardia, the esophageal carcinoma (hypomere) do not have the direct implant frame person of operation indication.
Claims (1)
1, a kind of stent in esophagus with anti-refulx membrane skirt, it by stainless steel silk skeleton, anti-displacement agnail, reclaim that nylon wire is compound to be formed with the medical grade silicon rubber film, it is characterized in that: the interior intracavity in shirt rim, support lower end 5 is provided with smaller, anti-refulx membrane skirt 6 that end opening is bigger suitable for reading, film skirt 6 is suitable for reading to have the bonding limit 7 of a smooth excessiveness with the rack bore bottom, and edge fit 7 forms one with the rack bore film.
