Abstract
The utility model discloses a prevent shifting biliary tract fully coated from expanding formula metal support, include that the formula of expanding certainly metal support (1) is the pipe network form from expanding formula metal support (1) and tectorial membrane (2), its both ends set up respectively expands part (3), and support tubulose part is woven by the wire and is formed, the material of tectorial membrane (2) is organosilicon high -molecular polymer and polyether polyurethane material, and tectorial membrane (2) are with the tubulose the pipe wall whole claddings in the outside from expand formula metal support (1). The biliary tract fully coated that should prevent shifting can prevent effectively from the formula metal support that expands that tumor tissue from through the support mesh support chamber of growing into, keeping the support chamber open, reduces the rate of treating again, and play and prevent the support translocation to prevent that the support became invalid.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of anti-displacement biliary tract full overlay film self-inflated metal
Support.
Background technology
Biliary tract self-inflated bare metal stent, half overlay film self-inflated metal rack and full overlay film self-inflated metal rack exist
Bile duct malignant stricture is extensively applied.Bile duct malignant stricture can be alleviated after Metal stent placement, draw in playing biliary tract
Stream effect, thus play reduction of patient obstruction of biliary tract but do not affect normal bile enterohepatic circulation.Three kinds of biliary tracts
Self-inflated metal rack is widely used in clinic the most, especially hypomere malignant obstruction in common bile duct.But biliary tract is certainly
The advantage of swollen formula bare metal stent is that stent drainage chamber is big, and support is difficult to displacement, but tumor tissues is easily from gold
Genus support mesh is grown into and is caused obstruction of stent.Half overlay film self-inflated metal rack and full overlay film self-inflated metal rack
Stent drainage chamber is identical with bare bracket, and it covers a tunic outside metal rack, thus avoids tumor tissues from gold
Belonging to support network ophthalmic to grow into, but stent migration rate is high, thus cause stent failure, serious shift support can damage
Hinder bile duct and intestinal, cause biliary tract, intestinal bleeding even to bore a hole.In order to solve the problem of above-mentioned existence, having must
Design a kind of with preventing tumor tissues from can prevent again metal rack from shifting from screening support chamber of growing into
Bile duct self-inflated metal rack.
Utility model content
Technical problem to be solved in the utility model is that existing biliary tract overlay film self-inflated metal rack easily moves
Position, thus cause stent failure.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of anti-displacement biliary tract full overlay film self-inflated metal rack, including self-inflated metal rack and overlay film, from swollen
Formula metal rack is pipe network shape, and its two ends are respectively provided with enlargement, and support tubular portion is by metal wire knitted
Become.Overlay film is all coated with outside the self-inflated metal rack tube wall of pipe network shape.
The enlargement often held is the round and smooth projection outside self-inflated metal rack, and round and smooth projection is radially
Upper continuous.
Along the longitudinal profile of self-inflated metal rack, enlargement be shaped as " Ω " shape.
The a diameter of 10mm of tube wall of the self-inflated metal rack of above described tubular.
Above-mentioned enlargement height of projection laterally is 2mm-3mm.
The corresponding end of peak of above-mentioned enlargement is 10mm along the distance of the axis of self-inflated metal rack.
Above-mentioned tinsel is selected from Nitinol or rustless steel.
The material of described overlay film is organosilicon macromolecule polymer and polyether-polyurethane material.
This anti-displacement biliary tract full overlay film self-inflated metal rack, is used for releasing malignant biliary obstruction.During use, should
Fang Yiwei biliary tract full overlay film self-inflated metal rack struts obstruction of bile duct section, thus plays the work releasing obstruction of biliary tract
With；Due to the whole overlay film of stent outer, can effectively prevent tumor tissues from being grown into support chamber by support mesh, protect
Hold support chamber open, reduce treatment rate again；Owing to the two ends of self-inflated metal rack are respectively provided with enlargement,
One end is positioned at the section of blocking near-end, and one end is positioned at the section of blocking far-end, plays and prevents stent migration effect, thus prevents
Stent failure.According to anti-displacement biliary tract of the present utility model full overlay film self-inflated metal rack, it is possible to reduce and control again
Treatment rate, thus reduce the number of times that patient support changes, alleviate patient suffering, improve the quality of living, meanwhile, because of
For reducing the expense that support is changed repeatedly, it serves the effect alleviating patient with social economical burden.
