Description
Technical field
This utility model relates to a kind of coated esophagus support, specifically, relates to a kind of two soft shirt rims rim of a cup and engraves window esophagus overlay film frame.
Background technology
Digestive tract is narrow to be a kind of common disease, comprises benign stricture and malignant stricture.Reach the purpose of the big esophagus tube chamber of support for the means that adopt nickel-titanium memory metal esophageal stents appear to insert esophagus more usually of malignant stricture.Yet, existing nickel-titanium memory metal esophageal stents appear, the stake body stage casing is cylindrical, expand at the support two ends, be rim of a cup shape, horn-like or bulb shape, the support two ends are exposed, and overlay film does not have the shirt rim, because the support two ends are overlay film not, therefore support is inserted in the short time of back and is easily caused lower edge mucous membrane of esophagus hypertrophy restenosis on the support, thereby has to settle second or even the 3rd support to solve problem, and this kind support is difficult for taking out.
Based on this, someone has designed a kind of full overlay film recoverable metal Esophageal Stent, it is that integral body with support all is covered with pellosil, though this kind support can not need to settle a plurality of supports to solve problem, and take out easily, but it is because diameter is less, and whole overlay film rear surface is comparatively smooth, therefore, this kind support is radial support power deficiency not only, and support displacement takes place easily or come off, thereby time one longly also be easy to generate the narrow problem of lower edge mucous membrane of esophagus hypertrophy on the support, be difficult to meet clinical needs.
Therefore, design a kind of metal Esophageal Stent that can prevent and be shifted easily or come off and the novel esophagus overlay film frame of lower edge mucous membrane of esophagus hypertrophy restenosis can not occur, become emphasis content for those skilled in the art.
The utility model content
The purpose of this utility model is to provide a kind of two soft shirt rims rim of a cup to engrave window esophagus overlay film frame, mainly solves existing metal Esophageal Stent and is shifted easily or comes off and the problem of lower edge mucous membrane of esophagus hypertrophy restenosis occurs.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Two soft shirt rims rim of a cup is engraved window esophagus overlay film frame, comprises the rack body that is woven into by Ultimum Ti, and this rack body is cylinder and two ends bulge; The rack body total length is 40～160mm, and its integral body is covered with pellosil, the diameter of section in described rack body stage casing is 18～20mm, the diameter of section of two ends bulge part is 20～32mm, and wherein an end bulge is partly gone up relative both sides and is equipped with the not opening of overlay film of surface, an end pellosil that is provided with opening at rack body extends to that it is outside and exceed 3～5mm and constitute first shirt rim, extends at rack body other end pellosil that it is outside and exceed 15～20mm and constitute second shirt rim.
As preferably, described rack body total length is 60～160mm.
As preferably, the area of described opening is 1
Further, the length of described rack body two ends bulges part is 15 or 20mm, and all be rim of a cup shape, its diameter of section is 24～30mm, be provided with on the relative other end of an end of opening with rack body and then be provided with the saw-tooth ring that constitutes by 6～8 monofilament, described second shirt rim is all identical with the length and the shape of saw-tooth ring, and second shirt rim overlays on the outside of this saw-tooth ring.
Compared with prior art, the utlity model has following beneficial effect:
(1) this utility model design is ingenious, easy to use.
(2) this utility model is by being provided with the mode of suitable size openings in the relative both sides of any end of rack body, make it behind granulation tissue hyperplasia, to pass from opening, thereby support can be fixed, add that stent diameter is bigger, radial force is also enough big, therefore the support displacement can not occur or come off, and first shirt rim and second shirt rim also make support have the characteristic of two soft shirt rims, can effectively alleviate the compressing power of support, thereby prevent lower edge mucous membrane of esophagus hypertrophy restenosis on the support esophageal wall.
(3) section diameter of this utility model bulge is greater than the diameter of mid portion, can further reduce the generation of support displacement, and the other end relative with being provided with opening one end be provided with saw-tooth ring, be with second shirt rim on this saw-tooth ring, therefore, it can allow patient feel comfortable.
(4) this utility model cost performance height, function is various, and it can be used for: 1, the esophageal carcinoma is narrow; 2, the stifled fistula of esophago-tracheal fistula/mediastinum fistula; 3, esophageal stoma benign stricture recoverable support, and when the second shirt rim length of the support of selecting for use was 20mm, it can be used as cardia anti-backflow support so its pointed strong characteristics, the utlity model has application prospects, be particularly suitable in medical domain, promoting the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, the name of the parts of above-mentioned accompanying drawing correspondence is called:
The 1-rack body, 2-opening, 3-first shirt rim, 4-second shirt rim.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, this utility model comprises rack body 1, and the netted cylindrical structure that this rack body 1 is woven into for Ultimum Ti, its total length are 40～160mm, be preferably 60～160mm in the present embodiment, and rack body 1 integral outer is covered with pellosil.The two ends bulge of rack body 1 all is rim of a cup shape, and diameter of section is 20～32 mm, and length is 15 or 20 mm, and in the present embodiment, its cross section is preferably 20～30 mm, and length is preferably 15 mm.In addition, an end bulge is wherein partly gone up relative both sides and is equipped with an opening 2, and the pellosil end that is provided with opening 2 at rack body 1 exceeds 3～5mm and form first shirt rim 3, and the area of opening 2 is 1
, it is used for behind the granulation tissue hyperplasia it being passed, so that fixing entire bracket, prevents the support displacement or comes off.Be provided with the relative other end of an end of opening 2 with rack body 1 and then be provided with the saw-tooth ring that constitutes by 6～8 monofilament, and exceeding 15～20 mm at this end of rack body 1, pellosil forms second shirt rim 4, and saw-tooth ring is consistent with the length and the shape of second shirt rim 4, and second shirt rim 4 overlays on the outside of saw-tooth ring.
This utility model in use, that end that rack body 1 is provided with opening 2 up, that end that is provided with saw-tooth ring down, then whole its put in the esophagus tube chamber, the big narrow esophagus of support, the digestion so that the patient can normally take food, because rack body 1 is provided with opening 2, therefore, when granulation tissue hyperplasia occurring in the esophagus tube wall, it can pass from opening 2, give rack body 1 one support forces, like this, rack body 1 just can be fixed in the esophagus tube chamber well, displacement can not occur and come off, and the two soft shirt rim structure that first shirt rim 3 that is provided with, rack body 1 two ends and second shirt rim constitute can prevent lower edge mucous membrane of esophagus hypertrophy restenosis on the support.When this utility model can make the patient can normally take food digestion it is treated, have very high practical value and promotional value, therefore, this utility model has the advantage of good fixing effect, convenient treatment, it has substantial characteristics and progress compared to existing technology.
According to the foregoing description, just can realize this utility model well.What deserves to be explained is; under the prerequisite based on the said structure design; for solving same technical problem; even some that make on this utility model do not have substantial change or polishing; the essence of the technical scheme that is adopted is still consistent with this utility model, also should be in protection domain of the present utility model.
