Description

A kind of anti-displacement Esophageal Stent instrument bag

Technical field

This utility model belongs to medical instruments field, relates in particular to a kind of the application and is related to a kind of anti-displacement esophageal branchess Frame instrument bag.

Background technology

In recent years, with the increasingly maturation of interventional technique, stent types are also more and more, wherein, Esophageal Stent is to controlling The application for treating the esophaguses class diseases such as esophagostenosiss, esophago-tracheal fistula has also gradually formed main flow, and achieves remarkable result.Esophaguses Support has the advantages that in such disease is treated wound is little, effect is rapid and safe and simple, poor especially for physical qualification, sick The more aobvious advantage of patient of journey time length, is effectively treatment method that other treatment meanss are difficult to substitute.

Esophageal Stent can be divided into according to overlay film situation：Without overlay film, part overlay film and full overlay film.But no matter implantation is which Support is planted, has stent migration and the risk for coming off.In order to prevent the generation of this risk, there are two methods：One be people from The improvement made on product structure is such as：At the Esophageal Stent lower end horn mouth mentioned in ZL99230617.5 Spure type esophagus dilators Several downward agnails of connection, agnail direction postpone direction in oblique outer lower shape in horn mouth, although this support good stability, It is difficult to glide, but if gliding to puncture blood vessel, causes massive hemorrhage, threat to life；For another example：Application number A kind of spiral of the Jing special constructions design being related in a kind of 201220198703.6 spiral type degradable Esophageal Stent patents Shape degradable Esophageal Stent, can the problem that easily slides in use of effectively solving support.But as biodegradable stent, to its mechanics Not enough all easily there are restenosiss in the requirement that performance and degradation property have which higher, too fast or support force of degrading, simultaneously for The risk for displacement occur for tract in esophaguses and coming off is also FAQs, and price is more much higher than metal class support. 20 doctors are doing such postoperative to prevent from shifting and coming off, then short cycle check is constantly carried out to patient, such as one week, Two weeks etc., support recovery will be carried out after it is determined that shifting, in case on-slip is fallen in stomach.Although this process can prevent support from taking off Fall, but allow patient to suffer from the pain of continuous check, while treatment cost is also considerably increased.

Therefore, now invent a kind of anti-displacement Esophageal Stent instrument bag, this kind of Esophageal Stent effectively can avoid displacement and The risk for coming off, and make patient reduce the pain of frequently check, while reducing treatment cost.
