Abstract
The invention discloses the anti-Esophageal Stents that backflows of one kind, including Coated Stents in Treatment of Benign and the anti-valve that backflows, Coated Stents in Treatment of Benign reticulates structure by metal wire knitted, it is whole to be covered by silica gel mantle, middle part is cylindrical, both ends are cylindrical in shape, anti- valve upper end of backflowing is fixed on the junction of Coated Stents in Treatment of Benign upper end tube body and middle part tube body, the anti-valve that backflows is made of wire armature and silica gel mantle, silica gel mantle is covered in by heat treatment on wire armature, the anti-valve upper end bore that backflows is with internal diameter of tube body in the middle part of Coated Stents in Treatment of Benign with wide, lower port is closed, in funnel-form, wire armature end is in hook formation.The configuration of the present invention is simple, easy to operate, low manufacture cost can effectively prevent food reflux caused by stomach wriggling.
Description
Technical field
The invention belongs to medical instruments fields, and in particular to the anti-Esophageal Stent that backflows of one kind.
Background technology
Medical domain solves the problems, such as esophageal obstruction for the lemostenosis multirow Esophageal Stent implantation caused by the cancer of the esophagus at present,
Make patient's esophagus smooth.After normal person's feed, this sphincter of oesophagus and stomach junction is closed, and food will not backflow entrance
Oesophagus causes to vomit, but for the narrow of oesophagus and stomach cardia connecting portion, destroy esophagus and cardia portion after Esophageal Stent implantation and include
About flesh so that food can be because stomach wriggling backflows after patients diet, and food enters oral cavity so as to which patient be caused to vomit from stent,
It is also possible to because food reflux causes esophagitis, pain is brought to patient.
Invention content
The present invention is of the existing technology in order to solve the problems, such as, provides a kind of simple in structure, good anti-of anti-effect of backflowing
Backflow Esophageal Stent.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
One kind of the present invention prevents the Esophageal Stent that backflows, including Coated Stents in Treatment of Benign and the anti-valve that backflows, Coated Stents in Treatment of Benign
Structure is reticulated by metal wire knitted, whole to be covered by silica gel mantle, middle part is cylindrical, and both ends are cylindrical in shape, the anti-valve that backflows
Upper end is fixed on the junction of Coated Stents in Treatment of Benign upper end tube body and middle part tube body, anti-to backflow valve by wire armature and silica gel
Mantle is formed, and silica gel mantle is covered in by heat treatment on wire armature, anti-valve upper end bore and the coated esophagus branch of backflowing
Internal diameter of tube body is with wide, lower port closure in the middle part of frame, and in funnel-form, wire armature end is in hook formation.
Further, Coated Stents in Treatment of Benign both ends tubular is any in bell mouth shape, rim of a cup shape, spherical shape, mushroom
Kind.
Further, Coated Stents in Treatment of Benign overall length 60-120mm, two end cross-section diameters be 16-23mm, middle part section
A diameter of 16-23mm.
Further, wire armature inside and outside wall is covered by silica gel mantle.
Further, wire armature is Ultimum Ti silk or stainless steel wire.
The beneficial effects of the invention are as follows：Prevent valve designs of backflowing present invention employs funnel-form, it is double inside and outside wire armature
Layer overlay film, when diet, water and food enter funnel-form by pedestal upper end and prevent the valve that backflows, wire armature by
Pressure can arch upward outward, open valve, and after food and water pass through, wire armature is restored to original state, and lower end is closed, when
Stomach is wriggled, and when food and water backflow, wire armature, which is under pressure, inwardly to arch upward, so as to which wire armature lower end is closed meeting
It is even closer, prevent food and water from backflowing；Wire armature end uses hook design, enhances the stability of structure, simultaneously
So that medical staff is when to patient's Stent Implantation, convenient for conduit is extracted, the configuration of the present invention is simple, anti-effect of backflowing is good.
Description of the drawings
Fig. 1 is the anti-Esophageal Stent structure chart that backflows.
1- Coated Stents in Treatment of Benign in figure, 2- prevent the valve that backflows, 3- wire armatures, and 4- wire armatures end is in hook-shaped knot
Structure.
Specific embodiment
With reference to the accompanying drawings and examples, technical scheme of the present invention is described in further detail.
One kind of the present invention prevents the Esophageal Stent that backflows, including Coated Stents in Treatment of Benign 1 and the anti-valve 2 that backflows, coated esophagus branch
Frame 1 is woven into reticular structure by Ultimum Ti silk, and whole to be covered by silica gel mantle, middle part is cylindrical, and both ends are in rim of a cup
Shape, anti-2 upper end of valve of backflowing are fixed on the junction of 1 upper end tube body of Coated Stents in Treatment of Benign and middle part tube body, prevent backflowing valve 2 by
Ultimum Ti silk skeleton 3 and silica gel mantle are formed, and silica gel mantle is covered in Ultimum Ti silk skeleton by heat treatment
On inside and outside wall, double-layer structure, the anti-2 upper end bore of valve that backflows with 1 middle part internal diameter of tube body of Coated Stents in Treatment of Benign with width, close by lower port
It closes, in funnel-form, 3 end of Ultimum Ti silk skeleton is in hook formation 4.Medical staff carry out Esophageal Stent operation when
It waits, conduit and seal wire is usually first inserted into, after Esophageal Stent then is placed to designated position along conduit and seal wire, by Esophageal Stent
It discharges and extracts conduit and seal wire, 3 end of Ultimum Ti silk skeleton is in hook formation 4, effectively reduces medical staff and exists
The resistance generated when conduit and seal wire is extracted, while further reduced the influence to the anti-valve 2 that backflows, is putting medical staff
It is more convenient in the operation of stent to enter.
Further, 1 overall length of Coated Stents in Treatment of Benign be 120mm, two end cross-section diameters be 23mm, middle part diameter of section
For 16mm.
It should be noted that：The embodiment of the present invention is preferred embodiment, rather than its limitations.It should be pointed out that for
It, without departing from the principle of the present invention, can also be to specific embodiment for those skilled in the art
It modifies or equivalent replacement is carried out to some technical characteristics, be regarded as in protection scope of the present invention.
