Abstract

The utility model discloses a reliable fast switching imbedding device which comprises an outer tube. A shape tube is disposed at one end of the outer tube. The outer tube sleeves an inner tube. A guide groove is formed in corresponding parts of the outer tube and the inner tube. A passage allowing a zebra guide wire to penetrate is formed from the guide groove to the center of the sharp tube. A guide tube is arranged in the passage. The diameter of the guide tube is larger than that of the zebra guide wire. One end of the guide tube extends out of the guide groove. The reliable fast switching imbedding device has the advantages that the device is guided by a special catheter, the zebra guide wire can smoothly penetrate the inner tube and the outer tube at a 100% success rate, and fast switching is achieved.

Description

One exchanges inserter more reliably fast

Technical field

This utility model relates to a kind of medical inserter device, particularly one and exchanges fast more reliably inserter.

Background technology

Exchange biliary tract rack inserter, can use short stroke seal wire fast, is adapted to exchange fast surgery systems, shorten operating time, doctor can control seal wire in person, reduces operation technique person, reduce complication, improve success rate of operation, stand good with duration stroke seal wire.Now conventional quick exchange inserter, first by zebra wire distal by go directly patient's sufferer place of endoscope, again zebra seal wire near-end is penetrated to quick exchange inserter inner tube, probably from inner and outer tubes, pass by a gradient part guiding at 250～300mm place zebra seal wire, by zebra seal wire proximal lock on endoscope's handle, at this moment push inserter, inserter enters sufferer place, final successful releasing bracket under the guiding of zebra seal wire.

Existing quick trade-to product inner tube is that cut hole indentation forms by a PEEK pipe, and zebra seal wire arrives a gradient guide elements by inner orifice and indentation part, by this part, zebra seal wire is drawn to inner and outer tubes.Because after existing inner tube indentation; easily form the importing obstacle of zebra seal wire; in operation, doctor needs scene to wear zebra seal wire; owing to having gradient and part transition; at this moment very high to the guiding requirement of gradient part, often there will be guiding bad, zebra seal wire once can not pass the phenomenon of inner and outer tubes; therefore often a lot of time of waste passes at zebra seal wire, and misoperation also can cause the inefficacy of zebra seal wire simultaneously.Due to the particularity of operation, can not put in advance zebra seal wire, because operation is seized every minute and second often, if therefore very become important technical problem through zebra seal wire fast simultaneously.

Utility model content

Utility model object: technical problem to be solved in the utility model is for the deficiencies in the prior art, provides one to exchange fast more reliably inserter.

In order to solve the problems of the technologies described above, the utility model discloses one and exchange fast more reliably inserter, comprise outer tube, one end of outer tube is provided with point pipe, outer tube is nested with inner tube, and the corresponding position of outer tube and inner tube is provided with gathering sill, extends to Jian Guan center be formed for the passage through zebra seal wire from gathering sill, in described passage, be provided with the guide pipe that diameter is greater than described zebra seal wire diameter, gathering sill is extended in one end of guide pipe.

In this utility model, the polyimides that described guide pipe is polyimide material.

In this utility model, described guide pipe pipe thickness is less than or equal to 0.05mm.

In this utility model, the part that described guide pipe extends gathering sill is provided with removable label.

This utility model is by original guide elements by increasing a guide pipe again in inner tube, guide pipe adopts new technologic material to elect polyimides (PI) as, and thickness of pipe wall is accomplished to 0.05mm.Had new structure, guide pipe can pass zebra seal wire from inner and outer tubes in 100% guarantee.

This utility model exchanges inserter fast, NiTi can be woven to biliary tract rack etc. and put into the body cavities such as gallbladder, pancreas, liver, urethra, plays the effect of drain.This utility model can expand to TTS intestinal support inserting device, cytology brush, biopsy forceps, foley's tube, papillotome, get stone sacculus and other ERCP products.

Beneficial effect: this utility model leads by dedicated conduits, can pass inner and outer pipes by 100% guarantee zebra seal wire smoothly, reaches quick exchange requirement.This utility model because of hypotube be to form with laser engraving, his concordance and stability can be controlled completely, manufacturing is good.Can, according to the inserter service condition of different parts, adjust laser engraving figure simultaneously, thereby easily meet the designing requirement of different parts inserter.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, this utility model is done further and illustrated, above-mentioned and/or otherwise advantage of the present utility model will become apparent.

Detailed description of the invention

As shown in Figure 1 to 4, the utility model discloses one and exchange fast more reliably inserter, comprise outer tube 1, the front end face of outer tube 1 is provided with point pipe 6, outer tube 1 is nested with inner tube 2, and the corresponding position of outer tube 1 and inner tube 2 is provided with gathering sill 7, and the center that extends to point pipe 6 from gathering sill 7 is formed for the passage through zebra seal wire 4, in described passage, be provided with the guide pipe 3 that diameter is greater than described zebra seal wire diameter, gathering sill 7 is extended in one end of guide pipe 3.The polyimides that described guide pipe 3 is polyimide material.The pipe thickness of guide pipe 3 is less than or equal to 0.05mm.The part that described guide pipe 3 extends gathering sill is provided with removable label 5.

This utility model operating procedure is as follows:

As shown in Figure 1 to 4:

1, before operation, first part guide pipe 3 is inserted to inner tube 2 from outer tube gathering sill 7, inner tube 2 and point pipe 6 stretch out inserter far-end; Because operation characteristic, zebra seal wire can not pass inner tube in advance.

2, by zebra seal wire 4, the passage forming along guide pipe 3 penetrates from far-end smoothly, and the other end passes outer tube 1.Finally guide pipe 3 is extracted out from zebra seal wire near-end, put into recyclable case;

3, zebra seal wire near-end is buckled on endoscope's handle by retaining ring, mobile inserter by inserter along zebra

Seal wire is sent into patient and is suffered from body place, and releasing bracket finally takes out inserter along zebra seal wire.

This utility model provides one to exchange fast more reliably inserter; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; not departing under the prerequisite of this utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
