Abstract
The utility model relates to an embedding duct cavity inner support of salivary duct. The utility model is characterized in that the inner support is a tubular support with two open ends which is knitted prepared by adopting nitinol shape memory alloy fiber (2).
Description
Technical field
This utility model relates to a kind of medical stent, particularly treats the implanted endoluminal stent of salivary gland occlusive disease.
Background technology
The salivary gland occlusive disease is because various local causes cause salivary ducts to block, salivation is discharged difficulty, body of gland is a kind of salivary gland inflammatory diseases of swelling repeatedly, be common clinical, frequently-occurring disease, mainly show as and show effect for a long time, repeatedly that conduit mouth is suppurated and halitosis, have a strong impact on patient's work and life.The common reason of pipe obstruction comprises calculus and stricture of salivary ducts etc.For the patient of calculus, under salivary gland endoscope, take out calculus and can cure; Yet for the obstruction that stricture of salivary ducts causes, therapeutic effect is but not good.Mainly adopt at the descending mechanical expansion of salivary gland endoscope at present, but often form cicatrix easily after surgery and cause narrow recurrence, curative effect is dissatisfied.
Summary of the invention
The purpose of this utility model is to provide a kind of implanted salivary ducts endoluminal stent, is used for the permanent expansion of conduit, effectively solves the problem of the narrow recurrence of postoperative of present Therapeutic Method.
A kind of implanted salivary ducts endoluminal stent described in the utility model weaves the tubular bracket of the both ends open of preparation for adopting the niti-shaped memorial alloy silk.
The length of described tubular bracket is 1cm to 5cm, and diameter is 1mm to 3mm.According to the scope and the degree of ductal strictures, select the length and the diameter that are suitable for.
This utility model constructs the implanted endoluminal stent that is exclusively used in salivary ducts, can be applicable to cause salivary gland occlusive disease patient because of ductal strictures clinically.Can put into this endoluminal stent in stenosis under the salivary gland endoscope visual field clinically, the temp.-controlled type Ultimum Ti will be expanded to the diameter of design, thus permanent inserting with dilating catheter.There is no like product at present both at home and abroad.Implanted salivary ducts endoluminal stent described in the utility model, being convenient to operation implants, and can not cause stimulation behind the implant into body to normal lumen wall, avoid granulation hyperplasia and formed restenosis, can be used for the permanent expansion of conduit, effectively solve the problem of the narrow recurrence of postoperative of present Therapeutic Method.
Description of drawings
Fig. 1 is the perspective view of implanted salivary ducts endoluminal stent described in the utility model.
Fig. 2 is the planar structure sketch map of Fig. 1.
The specific embodiment
A kind of implanted salivary ducts endoluminal stent described in the utility model as depicted in figs. 1 and 2, weaves the tubular bracket 1 of the both ends open of preparation for adopting niti-shaped memorial alloy silk 2.Manufacture method: preparing mould with medical material by technique scheme can produce.Manufactured materials: Nitinol (temp.-controlled type).
Illustrated size is not the actual size of product.Usually, described implanted salivary ducts endoluminal stent, the length of its tubular bracket 1 is 1cm to 5cm, diameter is 1mm to 3mm.During clinical use,, select the length and the diameter that are suitable for according to the scope and the degree of ductal strictures.
Using method: under the salivary gland endoscope visual field this endoluminal stent is placed stenosis, the temp.-controlled type Ultimum Ti will be expanded to the diameter of design, the permanent dilating catheter of inserting, the obstruction factor of releasing conduit.
Claims (2)
1, a kind of implanted salivary ducts endoluminal stent is characterized in that: weave the tubular bracket (1) of the both ends open of preparation for adopting niti-shaped memorial alloy silk (2).
2, implanted salivary ducts endoluminal stent according to claim 1, it is characterized in that: the length of described tubular bracket (1) is 1cm to 5cm, diameter is 1mm to 3mm.
