Background technology
At present, cancer is one of human three big disease killers, mortality is higher, but through studying intensively of medical and health circle personage recent decades, medicine constantly occurs, medical procedure also improves constantly, as the esophagostenosis that treatment causes because of malignant tumor, the clinician puts into support, to reach the purpose of expansion pipeline, be example with the esophageal carcinoma, the esophageal carcinoma is one of China's common malignant neoplasm in digestive tract, occupies the 6th in world's malignant tumor, once finding mostly to be middle and advanced stage, in, the modal problem of late esophagus cancer patient is in various degree narrow of esophagus, block swallowing of causing, feed is difficult, obviously influences patient's quality of life.Though have the difficulty of swallowing, take food of reduction of patient rapidly of inserting of stent in esophagus now, but after existing inner support is inserted, support is not tightly supportting esophagus all the time when no matter taking food or when not taking food, patient's foreign body sensation is apparent in view, the anti-stream of gastric content is a big drawback especially, significantly limited Clinical application of stent in esophagus, so that most of patient with esophageal carcinoma are difficult to accept the inner support treatment.
Summary of the invention
The objective of the invention is the deficiency for solving the problems of the technologies described above, a kind of self-constriction stent in esophagus is provided, to solve the narrow problem of the esophageal carcinoma, this invention effective expansion esophagostenosis section on the feed the time, and when non-feed state closure, also can effectively stop backflowing of gastric content, and obviously alleviate the foreign body sensation under the non-feed state of patient, the physiological that meets esophagus is wriggled, and has alleviated patient's slight illness sense.
The present invention is the deficiency that solves the problems of the technologies described above, the technical scheme that adopts is: a kind of self-constriction stent in esophagus, comprise collar, force transmitting board, support body and be set in the outer thin film cover of support body, fixedly connected with the thin film cover in the upper end of described support body, the thin film cover is cylindrical, collar is arranged on an end of support body, and collar links to each other with the thin film cover by connecting line, described force transmitting board is provided with the collar, the collar of force transmitting board is located on the collar, collar is provided with at least two force transmitting boards, described support body is made up of the telescopic unit that a plurality of vertical arrangements arrange, each telescopic unit is by two jig arm and many clamp ring is formed, article two, be X-shaped after jig arm is hinged, and the two ends of every jig arm are provided with hinge hole, neighbouring two telescopic units are positioned at two jig arm ends of the same side and distinguish hinged, described every pair of clamp ring is made up of the semicircle clamp ring that two openings are oppositely arranged, two semicircle clamp rings are separately positioned on two jig arm, all clamp rings are arranged on phase the same side on the support body, and set up on the clamp ring of the top telescopic unit the force transmitting board lower end on the described collar.
Brachium more than two jig arm of described each telescopic unit, its pin joint is greater than the brachium below the pin joint.
Also be provided with spacing ring on the described collar, the both sides of each collar are equipped with spacing ring, are used for the position of the restriction collar.
Described force transmitting board is sector structure, during original state, amplexiforms mutually between adjacent two force transmitting boards.
Described thin film cover is the silica gel thin film cover.
Beneficial effect
Self-constriction esophageal stents appear of the present invention, be used for solving the narrow problem of the esophageal carcinoma, place esophageal carcinoma patient's esophageal carcinoma displacement to put, effectively expand the esophagostenosis section in the time of on the feed, and when non-feed state closure, also can effectively stop backflowing of gastric content, and obviously alleviate the foreign body sensation under the non-feed state of patient, the physiological wriggling that meets esophagus, alleviation patient's feed misery.

The specific embodiment
As shown in the figure, a kind of self-constriction stent in esophagus, comprise collar 1, force transmitting board 2, support body and be set in the outer thin film cover 3 of support body, described thin film cover 3 is the silica gel thin film cover, the displacement of extruding esophageal carcinoma is put under the effect of support body on the one hand, feed is become easily, on the other hand, can prevent that also tumor from inwardly growing from the hole of support body.The upper end of described support body is overlapped 3 with thin film and is fixedlyed connected, and support body and thin film cover 3 can not come off mutually.It is 3 cylindrical that thin film overlaps, and collar 1 is arranged on an end of support body, and collar 1 one ends are the top, and collar 1 links to each other by connecting line and thin film cover 3, and collar 1 and thin film are not broken away between overlapping 3 mutually.Described force transmitting board 2 is provided with the collar 4, the collar 4 of force transmitting board 2 is located on the collar 1, force transmitting board 2 can be by the collar 4 in collar 1 rotation, also be provided with spacing ring 7 on the described collar 1, the both sides of each collar 4 are equipped with spacing ring 7, be used for the position of the restriction collar 4, each force transmitting board 2 can only be rotated in the position of oneself.Another kind of embodiment, as shown in Figure 6, described force transmitting board 2 is sector structure, during original state, amplexiforms mutually between adjacent two force transmitting boards 2.Wherein, collar 1 is provided with at least two force transmitting boards 2, a plurality of force transmitting boards 2 are evenly distributed on the collar 1, described support body is made up of the telescopic unit that a plurality of vertical arrangements arrange, each telescopic unit is by two jig arm 5 and many clamp ring 6 is formed, article two, be X-shaped after jig arm 5 is hinged, two jig arm 5 of described each telescopic unit, brachium more than its pin joint is greater than the brachium below the pin joint, like this, after the uppermost clamp ring 6 of telescopic unit is stressed, through long-armed and pin joint to bottom clamp ring 6 places, the amplification effect with power.And the two ends of every jig arm 5 are provided with hinge hole, neighbouring two telescopic units are positioned at two jig arm 5 ends of the same side and distinguish hinged, when being positioned at top telescopic unit expansion, telescopic unit below driving is expanded simultaneously, when being positioned at top telescopic unit contraction, the telescopic unit below driving shrinks simultaneously.Described every pair of clamp ring 6 is made up of the semicircle clamp ring that two openings are oppositely arranged, and two semicircle clamp rings are separately positioned on two jig arm 5, and clamp ring 6 can be fixed up with thin film cover 3 places that contact.Clamp rings 6 all on the support body are arranged on phase the same side, and set up on the clamp ring 6 of the top telescopic unit force transmitting board 2 lower ends on the described collar 1.
Self-constriction esophageal stents appear of the present invention, place esophageal carcinoma patient's esophageal carcinoma displacement to put, when the patient swallows food, food can press down force transmitting board 2 when collar 1 falls, force transmitting board 2 presses down on the clamp ring 6 of top telescopic unit, make a pair of clamp ring topmost 6 expansions, leverage by jig arm 5 in the time of expansion makes 6 expansions of clamp ring bottom that are in same telescopic unit, adjacent two telescopic units are hinged by jig arm 5, realize expanding simultaneously and shrinking, effectively expand the esophagostenosis section in the time of on the feed, and when non-feed state closure, also can effectively stop backflowing of gastric content, and obviously alleviate the foreign body sensation under the non-feed state of patient, the physiological wriggling that meets esophagus, alleviation patient's feed misery.
