Abstract
The utility model relates to medical equipment field comprising a bracket body and an inner lining membrane adhesive to the inner side of the bracket body. The initial end of the bracket body is provided with two annulus protruding objects. The inner lining membrane is provided with an extension part extending out of the rear end of the bracket body and the bracket is fixed in a relative firmly manner and not easy to lead to the movement or breaking off of the bracket. In addition, the inner lining is made as the silicon gel membrane material layer to prevent tumor from growing from the bracket mesh inward so as to reduce the occurrence of narrowness of esophagus once more and avoid the returning of the bracket body inside the stomach, reduce the pain of patient and enhance the treatment effects.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of Esophageal Stent of the auxiliary treatment esophageal carcinoma.
Background technology
The esophageal carcinoma is the malignant tumor of esophagus squamous epithelial cancer, carrying out property dysphagia is its most typical clinical symptoms, serious absorption obstacle due to the solution thoracic choke, improve patient's quality of life, life-saving is basic treatment measure, and what use in the hospital at present all is traditional single bulb or rim of a cup shape Esophageal Stent, also can remove thoracic choke though be positioned over the distal esophagus pars cardiaca, and single bulb or rim of a cup shape Esophageal Stent treatment distal esophagus carcinoma of gastric cardia, before the art, though the location is very accurate in the art, but support is found in the postoperative barivm meal fluoroscopy (screem) moving down in various degree often arranged, even the support person that is shed to the gastral cavity, and esophageal reflux appears in most patient, cause complication such as restenosis easily, easily cause doctor-patient dispute, curative effect is undesirable, brings great misery to patient.
Summary of the invention
Technical problem to be solved in the utility model is: for solving above-mentioned deficiency, provide a kind of and be difficult for causing that support moves down, comes off, be difficult for causing regurgitation of food, esophagus restenosis etc., the better Esophageal Stent of therapeutic effect.
For achieving the above object, the technical solution of the utility model is: improved Esophageal Stent, it comprises rack body and attached to the inner lining film of rack body inboard, the top of described rack body is provided with two annular protrusions, and described inner lining film has the extension that stretches out the rack body tail end.
Owing to adopted technique scheme, improved Esophageal Stent, it comprises rack body and attached to the inner lining film of rack body inboard, the top of described rack body is provided with two annular protrusions, described inner lining film has the extension that stretches out the rack body tail end, support top is two annular bulbs, increasing resistance between esophagus and support with this better prevents and treats the support displacement and reduces support and come off, support is netted Nitinol metal level, be self-expandable stent, meet cold deliquescing, the chance thermal change is hard, and function admirable is very desirable to narrow expansion support effect, the support liner prevents that with the silica gel rete tumor from inwardly growing from the support mesh, thereby reduce the generation of esophagus restenosis, the liner pellosil of Flos Mume lobe or flat mouthful of shape continuity is made in the support lower end, has avoided backflowing of gastric content well, better improve therapeutic effect, slowed down patient's misery.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment
As shown in the figure, improved Esophageal Stent, it comprises rack body 1 and attached to the inner lining film 2 of rack body 1 inboard, the top of described rack body 1 is provided with two annular protrusions 3, described inner lining film 2 has the extension that stretches out rack body 1 tail end, described two annular protrusions 3 comprise first annular protrusion 31 and second annular protrusion 32, between described first annular protrusion 31 and second annular protrusion 32 is smooth connection, described rack body 1 is a Nitinol network structure layer, the lower end of described rack body 1 is Flos Mume lobe or flat mouthful of shape, so in use, because the annular protrusion 3 of two bulb shapes is arranged, can increase the resistance between esophagus and the support, can better prevent support displacement or come off, between described first annular protrusion 31 and second annular protrusion 32 is smooth connection, two annular protrusions 3 help better increasing the frictional force between support and esophagus, described rack body 1 is by netted Nitinol network structure layer, be self-expandable stent, meet cold deliquescing, the chance thermal change is hard, function admirable, the lower end of described rack body 1 is Flos Mume lobe or flat mouthful of shape, neither influence feed, prevent that again gastric food from backflowing, described inner lining film 2 is the pellosil material layer, prevents that tumor from inwardly growing from the support mesh, thereby reduce the generation of esophagus restenosis, attached to the inside of rack body 1.Can make the support of the model that is uneven in length, clinical patients for different lesions length is used, spot film before operation, the capable X line perspective of oral barium agent or 76% cardiografin location (upright position is in conjunction with horizontal position) in the art, body surface labelling font, select the support of suitable length, stent length grows length of lesion 4cm and is advisable, be that the support two ends respectively grow pathological changes 2cm, according to design before the operation, the carcinoma of gastric cardia patient expands part more than cardia in the middle of making support as far as possible, to stop rack body 1 to move down or to come off, the distal esophagus pathological changes, the part of expanding in the middle of when support is placed is placed on diseased region, should not go esophagostenosis section predilation before the operation, further expansion when undesirable of expanding of postoperative support, in case the narrow releasing resistance in expansion back reduces, support moves down, because rack body 1 immobile phase is to firmly, the probability that therefore retrosternal pain takes place is less, two annular protrusion supports 3 have avoided the support upper end-face edge that esophagus answered shear force and frictional force, having reduced support damage esophagus causes hemorrhage, the generation of ill effects such as hypertrophy, thus patient's misery alleviated, also improved therapeutic effect.
