Description

A kind of new uropoiesis and digestive endoscope zebra superslide seal wire
Technical field
The present invention relates to field of medical technology, a kind of new uropoiesis and digestive endoscope are particularly related to super with zebra Sliding seal wire.
Background technology
Due to the continuous progress of interventional medicine, in the urinary tract and digestive endoscope diagnosis and treatment process, seal wire be deep into it is defeated The process of urinary catheter, renal plevis or bile duct biliary tract plays important guiding and importing effect, and the zebra pigment figure on its surface is led beneficial to observation The movement or indexing of silk.The such guiding of seal wire and importing act as the introducing of subsequent conduit or support, contrast agent injection, knot Stone basket insertion etc., all serves indispensable effect.However, traditional zebra guide wire has two kinds of defects:
1, the PTFE heat-shrinkable tubes that the upper whole section of use of construction of zebra guide wire is printed on zebra-stripe, which are contracted on plug, to be made, preceding Hold the levigate plug of taper, but due to the limitation of PTFE material hardness, cause the front end mistake of the zebra guide wire despite the use of Firmly, the operating difficulties when guiding imported into ureter or bile duct, especially representative is the more boston, U.S.A of Clinical practice The uropoiesis zebra guide wire of scientific company production.
2, what zebra guide wire surface was contacted with uropoiesis and gastrointestinal mucosal is PTFE plastics, and the plastic surface can not carry out parent Water coating and cause the direct hard contact of plastic or insert draw a mucous membrane, mucosa injury is caused unavoidably.
Comparatively ideal the urinary tract and digestive endoscope zebra guide wire should be not only easy to observation, and seal wire front end should also be relatively soft In favor of guiding import operation, such as enter ureter and biliary tract bile duct, its Facing material preferably realizes hydrophilic coating, to ensure Contact mucosal tissue and be unlikely to cause mucosa injury when uropoiesis and alimentary canal are slided.
The content of the invention
For deficiency of the prior art, the technical problem to be solved in the present invention is the provision of a kind of new uropoiesis and disappeared Change road scope zebra superslide seal wire.
In order to solve the above technical problems, the present invention is realized by following scheme:A kind of new uropoiesis and digestive endoscope With zebra superslide seal wire, the cunning seal wire includes NiTi inner core rod, medical polyurethane material clad, hydrophilic coat, the doctor NiTi inner core rod outer surface is coated on polyurethane material clad, and is coated with medical polyurethane material clad outer surface Hydrophilic coat;
The imports end of the NiTi inner core rod is provided with tapered section of taper;
The imports end of the medical polyurethane material clad is provided with tapered section of taper, and its surface is provided with tilting zebra-stripe, and Hydrophilic coat is scribbled in the tilting zebra-stripe and the other surface regions of medical polyurethane material clad.
Further, the hardness of the medical polyurethane material clad is 35D to 40D.
Further, it is tapered section of taper at the imports end 10-15cm of the NiTi inner core rod.
Further, when the NiTi inner core rod outside diameter is 0.6mm, its imports end end diameter is 0.18mm-0.22mm.
Further, the combination external diameter formed after medical polyurethane material clad cladding NiTi inner core rod is 0.8mm-0.83mm。
Further, the hydrophilic coat is pharmaceutical grade cross-linked pvp coat.
A kind of new uropoiesis and the digestive endoscope preparation method of zebra superslide seal wire, the preparation method include following step Suddenly:
Step one, the making of NiTi inner core rod:One section of interception meets the Ultimum Ti of seal wire external diameter and guidewire length requirement Wire rod, first, by Ultimum Ti wire rod through being ground to outside tapered section of the tapers of front end 10-15 centimeter lengths, NiTi inner core rod When footpath is 0.6mm, its imports end end diameter is 0.18mm-0.22mm;
Step 2, medical polyurethane material clad coats the making of NiTi inner core rod:Will from the rear end of head of plastic extruder NiTi inner core rod butt end insertion, whne NiTi inner core rod at extruder head mouth mold out when, connection constant speed drawing machine constant speed to Preceding drawing realizes that the polyurethane of seal wire represents the cladding for having zebra-stripe;
Step 2, hydrophilic coat:After the pharmaceutical grade PVP solution for preparing debita spissitudo, polyurethane will be coated in step 2 NiTi inner core rod total length immerse in pharmaceutical grade PVP solution, then vertically above carried with 3-6cm per second speed, until propose Pharmaceutical grade PVP liquid level of solution, and dried up under 90 degree of -100 degree hot blast.
Relative to prior art, the beneficial effects of the invention are as follows:The new uropoiesis of the present invention and digestive endoscope are slided with zebra The more traditional zebra guide wire in seal wire front end is more soft, beneficial to the guiding import operation of seal wire;Seal wire full section surface parent of the present invention Water coating can reduce the friction with the urinary tract and gastrointestinal mucosal or caused may damage.The sliding seal wire clinical practice of the present invention makes Show that the cunning seal wire clinical widely used zebra guide wire more traditional in controllability, guiding importing performance is more preferable after; The sliding seal wire of the present invention shows fabulous sliding capability on uropoiesis and gastrointestinal mucosal, can greatly reduce tissue damage.
Brief description of the drawings
