Abstract
The utility model belongs to the technical field of medical appliances, in particular relates to a NiTi-based shape-memory alloy (SMA) biliary tract Y-shape bracket and an introducing appliance (introducer) for delivering the bracket. The front part of the biliary tract Y-shape bracket that is braided from the NiTi-based shape-memory alloy (SMA) is separated into two branches and the included angle between the branches is 60 degree. The Y-shape bracket can randomly be deformed at the room temperature. When the temperature reaches the temperature of the human body, the Y-shape bracket can immediately and spontaneously recover to the original designed shape so as to expand the narrow obstruction part of the supporting branch biliary duct but also to expand the narrow pathological changes of the main biliary duct obstruction in the branch liver, which has solved the unfavorable pattern that the straight bracket can only dredge the biliary duct in a branch liver. The front part of the introducer is diverging in a Y-shape with the included angle of the fork of 60 degree to be matched with the angle of the Y-shape bracket angle. The introducer is composed of a core pipe, a positioning pipe and an external bushing pipe. When the introducer is positioned into the area of pathological changes, wire drawing technology and external bushing shedding method are applied to discharge the bracket. The utility model has the advantages of convenient operation, safety and security and quick effect, which is an innovative plan for treating the difficult and baffling diseases on biliary tract and is involved in a new therapy progress.
Description
This utility model title is " biliary tract Y type support and a novel inserter ", belongs to technical field of medical instruments.
Background technology:
Current domestic and international medical circle application of treatment stenosis of bile duct blocks the support product of disease, all are single straight barrel shape, can only treat the interior narrow pathological changes of blocking of rectilinear form of house steward in the liver, there are the narrow case history of blocking simultaneously in hilar bile duct and stones in intrahepatic bile duct, can't use support and effectively treat, to remove sufferer.This mainly is because the current apparatus of inserting that does not also have a kind of suitable special-shaped support and be applicable to special-shaped support.This present situation can not satisfy the needs of medical development.
The utility model content:
The purpose of this utility model is to overcome the deficiency in the prior art and starts the therapy that makes new advances, and can treat in operation that the bile duct crooked position is narrow to be blocked and be present in simultaneously obstruction of common bile duct and branch's stenosis of bile duct and block the Y type biliary tract rack of pathological changes and insert apparatus accordingly and provide a kind of.It is characterized in that: Y type support is to be worked out by niti-shaped memorial alloy silk material, and the support front end is split up into two branches, and angle is 60 ° between branch, can change corner dimension according to the case history needs, to adapt to the curved narrow position.Y type support front end branch and substrate holder are an integral body, and diameter is Ф 8mm, and length is established different size according to the diseased region size.
Inserter is the apparatus that loads Y type support, its shape is a Y-shaped, be to make in order to load the special design of Y type support, inserter is made by the high-quality medical plastic catheter, front end is a Y font bifurcated, and the prong angle is 60 °, and inserter is by the core pipe, positioning pipe and trocar sheath are matched to a complete assembly, are convenient to be written into Y type support and insert the human body affected part smoothly.
Inserter front end trocar sheath longitudinal opening is divided into two branch joints, the support branch of packing in the sleeve pipe, and sleeve pipe external medical wire binding fixed constraints branch diameter adopts backguy technology dispensing support less than 2.8mm.After support is inserted the lesion, pull out fixedly silk thread, the spontaneous dispensing of branch's support, firmly strut branch stenosis of bile duct position, the mediation bile duct is deviate from total sleeve pipe and branch joint then, make the dispensing of common hepatic duct support strut narrow positions, deviate from core pipe and positioning guide wire, operation is finished.
This utility model superiority:
1. the design Y type biliary tract prosthesis adopts niti-shaped memorial alloy silk material to be compiled into network structure, has shape memory effect, and super-elasticity and excellent biological compatibility are ideal engineering in medicine materials.Y type support at room temperature can be out of shape arbitrarily, and support spontaneously returns to original solid shape immediately when reaching human body temperature.Strut the luminal stenosis diseased region, eliminate pathological changes.At room temperature stent diameter is compressed to below the Ф 3mm earlier before using, in the inserter trocar sheath of packing into, support and inserter form a complete assembly, and application is provided.
During clinical practice, inserter is inserted patient's diseased region along positioning guide wire, release Y type support by the positioning pipe in the inserter, under human body temperature, support discharges and spontaneously is expanded to former regulation shape immediately, and common hepatic duct and branch's stenosis of bile duct region of obstruction are strutted, and the mediation tube chamber is eliminated sufferer.
2. biliary tract Y type rack surface can fuse good biocompatibility and elastic pellosil or knitting film, can be made into the band film or is not with the film product according to the case history needs.
3. biliary tract Y type support can be disposable be treated the stenotic lesion that blocks of house steward in branch's bile duct regulating liver-QI simultaneously, has avoided second operation and can only dredge single luminal stenosis etc., treats not thoroughly, can not eliminate the drawback of sufferer fully.
4. biliary tract Y type support adopts silk thread fixing fixing, safe and reliable with the sleeve pipe compression in inserter, inserts smoothly.
5. after inserter is inserted diseased region, adopt the backguy technology and throw off the trocar sheath technology, discharge Y type support fast, Y type support spontaneously restores to the original state immediately under human body temperature, and diseased region is supported in expansion, eliminates sufferer.
6. novel inserter is that special design is made according to the special shape of biliary tract Y type support, inserter all adopts high-quality medical plastic catheter structure, by the core pipe, localizer and trocar sheath combine, the core bore can pass through positioning guide wire, to guarantee to insert lesion locations, the positioning pipe termination holds out against Y type support end, to guarantee the back release support smoothly that puts in place, trocar sheath compressed stent fixed diameter support is in inserter, and inserter front end bifurcated goes out two arms, and angle is 60 ° between two arms, two arm diameters are less than Ф 2.8mm, house steward's diameter is less than 4.5mm, and is tight to guarantee the compression of Y type support, and can be according to the shape adjustments orientation and the angle of patient's diseased region.The length of inserter is according to clinical easy to use being decided to be about 300mm.
