Description

Spray door benign and malignant stenosis patient's Esophageal Stent

Technical field

The utility model relates to field of medical technology, specially a kind of spray door benign and malignant stenosis patient's Esophageal Stent.

Background technology

Esophageal stents are typically to be worked out by Ultimum Ti silk screen, and some rack surfaces are also coated to silicon rubber thin Film, encloses the mesh of naked frame, to prevent proliferative lesion from entering inside tube chamber by mesh, does not result in narrow again.

Human body oesophagus can be blocked oesophagus in the event of tumour or canceration, cause patient to swallow food and it is hungry and Extremely, especially for spray door benign and malignant stenosis patient, oesophagus is strutted using esophageal stents generally, expands lesion esophageal site Intracavity diameter, is passed through with instant food.After conventional Ultimum Ti Esophageal Stent is laid, discovery has the oesophagus of many patients Diseased region is blocked again, and it is difficult to cause to swallow food, through x-ray fluoroscopy, find because esophageal peristalsis and swallow coarse granule food will Ultimum Ti Esophageal Stent is pushed away and dropped down onto in stomach, it usually needs use special shearing apparatus with the help of gastroscope by NiTi The Esophageal Stent that memorial alloy is made is sheared broken bit by bit, then is taken out one by one by biopsy forceps, then lays again One Esophageal Stent of new Ultimum Ti, performs the operation extremely complex, and patient is very painful, and prolonged operation increases doctor Labour intensity, also increase the medical expense of patient.

Notification number discloses a kind of bellows-type anti-dropout Esophageal Stent for the utility model patent of the U of CN 204260878, To solve the above problems, but the reliability of its anti-displacement is not still good enough, and Esophageal Stent is difficult conjunction long with patient's esophagus one Rise, poor reliability, and patient's food reflux phenomenon can not be prevented effectively from.

Utility model content

The purpose of this utility model is to provide one kind can effectively prevent Esophageal Stent from coming off, and effectively promotes support and suffer from Person's esophagus is long to be combined, and makes the fixation of support more solid and reliable, it is to avoid to be performed the operation again to patient, causes unnecessary pain Bitter spray door benign and malignant stenosis patient's Esophageal Stent.

The technical solution of the utility model：

To achieve the above object, the utility model provides following technical scheme：One kind spray door benign and malignant stenosis patient's food Pipe holder, including two ends are the esophageal stents membrane tube body of bell-mouth structure of air, and the expansion face of the bell-mouth structure of air is outwards to arch upward Arcuate structure, the outer surface of the membrane tube body is laid with the tennis that some woven wires are worked out.

The tennis is laid at the bell-mouth structure of air of the membrane tube body.

The sacculus that pellicle is made is provided with the tennis.

It is semicircular ring network cylinder that the section that woven wire works out is additionally provided with the membrane tube body.

The annular anther sac that pellicle is made is provided with the ring network cylinder.

The membrane tube inner body wall is provided with the anti-valve that backflows.

The membrane tube body includes two sections, and the center line of two sections is in 120-150 ° of angle.

Positive beneficial effect of the present utility model：

Compared with prior art, the utility model is by using the bell-mouth structure of air for outwards arching upward and being laid with some metals The esophageal stents membrane tube of the tennis structure that silk screen is worked out, on the one hand, the bell-mouth structure of air for arching upward, makes support and patient's esophagus Greater area of contact is formed, and patient's esophagus is effectively strengthened the supporting force of support, on the other hand, tennis eats patient Road is more further dramatically increased with the contact area of support, and contact stabilization is more preferable, meanwhile, tennis structure makes patient's esophagus pair Its formation effectively cladding, more solid and reliable to esophageal stents formation effectively firmly grasps, and then length is combined, so that oesophagus The fixation of support is more reliable and more stable, is prevented effectively from the generation of stent migration situation.

Further, sacculus and annular anther sac that pellicle is made are set by tennis and ring network cylinder, can Effectively realize coordinating by insoluble drug release, patient's lesions position is effectively treated, while being easy to booster action, mitigate patient The pains such as foreign body sensation, improve patients ' life quality.The anti-valve that backflows is set by membrane tube inner body wall, patient can be prevented effectively from When couching, food reflux makes patient in limited life time, enjoys the life closer to ordinary person.

Another step, using center line in the 120-150 ° of two sections structure of angle, two sections can be with for membrane tube body Split is connected, it is also possible to integrally connected, by the bending cambered structure for setting, Oesophageal physiological bending is more conformed to, so that effectively Prevent bracket slide from coming off, and contribute to the anti-reliability and practicality for backflowing, further improving Esophageal Stent.

The utility model simple structure, designs ingenious, and the reliability of anti-displacement is significantly improved, and can effectively improve trouble The quality of life of person, practical, should be widely promoted application.
