Abstract
A kind of bottle shape stent in esophagus being applicable to treatment high position of esophageal stenosis, comprise by the cylindrical shape net cribbing woven and the inner lining film be attached on support, it is characterized in that: cylindrical shape net cribbing is up-thin-low-thick bottle shape structure, and the opening part at the upper and lower two ends of support is all in the mushroom head of outside bulging.The beneficial effects of the utility model are: the structure that 1, support is up-thin-low-thick is compared with the common esophageal stents appear of straight-tube shape, and compliance is better, and to fit better tract inwall at human body epimere esophagostenosis, reduce displacement.2, the mushroom head that support two ends are expanded can reduce the stimulation to bottleneck throat.3, processing technology is simple and convenient, and comparatively import support is lower for price, and cost performance is high.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of for expanding human body epimere esophageal stricture, makes the stent in esophagus that it is unobstructed.
Background technology
The various Malignant and benign lesions of esophagus all can cause esophagostenosis as the growth of caustic stricture of esophagus, malignant tissue infiltrates, and cause patient can not swallow food and hungry and dead, serious threat human body is healthy, even threat to life.Esophageal stents appear placement in the treatment effectively can be alleviated rapidly dysphagia, recover feed, improves the quality of living, and has won the time for treating further.But in clinical practice, there is many difficult problems for high position of esophageal stenosis, the Esophageal Stent as common is inserted, and because narrow location is top, ordinary stent is easily shifted, and comes off and enters gastric, cannot play therapeutic effect.Bottleneck throat and epimere esophagus are compared with middle hypomere simultaneously, neural abundant, more responsive, thicker Esophageal Stent easily stimulates bottleneck throat and Upper Esophageal, causes patient pain hard to bear, and even neck swelling tracheas suppressed causes and suffocates, most of patients cannot resistance to suffer, requires again to take out support.
The defect of above-mentioned common Esophageal Stent significantly limit the application of stent in esophagus in the treatment of epimere esophagostenosis.
Summary of the invention
The purpose of this utility model is just for problem existing for above-mentioned prior art, the defect of strong, the easy slippage displacement of the poor compliance of rear appearance, patient's foreign body sensation and pain is inserted in order to overcome common Esophageal Stent, and custom-designed a kind of bottle shape stent in esophagus with the applicable treatment high position of esophageal stenosis of good adherent effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bottle shape stent in esophagus being applicable to treatment high position of esophageal stenosis, comprise by the cylindrical shape net cribbing woven and the inner lining film be attached on support, wherein: cylindrical shape net cribbing is up-thin-low-thick bottle shape structure, and the opening part at the upper and lower two ends of support is all in the mushroom head of outside bulging.
In this utility model, all curved corner transition structure in reducing place and reducing place, middle part at the two ends up and down of cylindrical shape net cribbing.
The inner lining film be attached on support is macromolecular lining film, specifically can be medical polyurethane, politef, silicone rubber, dacron membrane or polyethylene, ePTFE thin film, weaving PET thin film.
Thin segment and the thick section diameter ratio of the support of bottle shape structure are 1:1.5-2, and the length ratio of its thin segment and thick section can be determined according to concrete practical situation.
In this utility model, the material forming support is alloy material, macromolecular material or degradation material.
The thickness of this stent in esophagus and length all can according to clinical requirement Individual designs, and the material forming Esophageal Stent wire rod can be alloy material (comprising rustless steel, nitinol alloy wire), macromolecular material (as polyethylene, polyurethanes, politef) or degradation material (PPDO, polylactic acid, polyglycolic acid etc.).
The beneficial effects of the utility model:
1, inner support of the present utility model uses single form of presentation to make by single wire rod, and its compliance is good, and tract inwall of fitting better in human body epimere esophagus, can reduce the stimulation to throat and esophagus.2, compare straight barrel type esophageal stents appear, the steadiness of this support is stronger, is not easily shifted.3, because support two ends are in the mushroom head expanded, easily block narrow section, and better adherent at esophagus two ends, not easily food retains, and reduce the friction of support and esophagus.4, support forms by monofilament is integrated weaved, and processing technology is simple and convenient.5, support can be designed to the size of different size, is applicable to the needs of Different Individual; 6, in operation, there is conveying easy, reliable etc.; 7, in price, comparatively import support economy, patient can accept mostly, and cost performance is higher.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
In figure: 1. mushroom head, 2, thin segment support, 3, thick section support, 4, inner lining film.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
A kind of bottle shape stent in esophagus being applicable to treatment high position of esophageal stenosis, comprise by the cylindrical shape net cribbing woven and the macromolecular lining film 4 be attached on support, wherein: cylindrical shape net cribbing is up-thin-low-thick bottle shape structure, namely two sections diameter is different, thin segment support 2 and thick section support 3 diameter ratio are 1:1.5-2, both can determine according to concrete practical situation by length ratio, and the mushroom head 1 of the opening part at the upper and lower two ends of support all in outside bulging.
The all curved corner transition structure in reducing place and reducing place, middle part at the two ends up and down of cylinder mesh cribbing.
Support of the present utility model forms by individual thread is integrated weaved, the mushroom head 1 that wherein two ends are expanded plays the adherent effect with preventing from being shifted with esophagus, thinner neck brace plays the effect removing esophageal stricture, thicker holder part plays support bracket fastened effect, and inner lining film plays shutoff fistula mouth, prevents the effects such as granulation tissue hyperplasia.
The maximum feature of this support be can place esophagus higher part position narrow to alleviate reaction, prevent displacement, to remove the effects such as narrow.
The occupation mode of this overlay film frame is as follows:
Before using, esophageal stents appear first compresses and inserts stent conveying device by patient, in use procedure, guided by seal wire, under the Lookout assist effect of X line or endoscope, support delivered to esophageal stricture position and discharge, support is fixed on the lesion in esophagostenosis exactly, again recovers shape gradually and expand to strut esophagus, and tube wall of well fitting.
