Abstract
The invention discloses a more reliable fast exchanging imbedding device. The more reliable fast exchanging imbedding device comprises an outer pipe, one end of the outer pipe is provided with a sharp pipe, an inner pipe is embedded into the outer pipe, the position, corresponding to the inner pipe, of the outer pipe is provided with a guiding groove, a channel for a zebra wire to penetrate through is formed from the guiding channel to the center of the sharp pipe, the channel is internally provided with a guiding pipe with the diameter larger than that of the zebra wire, and one end of the guiding pipe extends out of the guiding groove. By means of the guiding of the special guiding pipe, the zebra wire can penetrate out of the inner pipe and the outer pipe successfully, and the fast exchanging requirement can be met.
Description
Technical field
The present invention relates to a kind of medical inserter device, particularly a kind of more reliable quick exchange inserter.
Background technology
Quick exchange biliary tract rack inserter, can use short stroke seal wire, be adapted to quick exchange surgery systems, shorten handss
The art time, doctor can control seal wire in person, reduces operator, reduces complication, improves success rate of operation, with duration row
Journey seal wire stands good.The quick exchange inserter now commonly used, the disease of the patient that first zebra guide wire far-end gone directly by endoscope
Affected part, then zebra guide wire near-end is penetrated quick exchange inserter inner tube, probably at 250～300mm, zebra guide wire passes through one
Individual gradient part guiding passes from inner and outer tubes, by zebra guide wire proximal lock on endoscope's handle, at this moment pushes and inserts
Device, inserter enters at sufferer under zebra guide wire guiding, finally successfully discharges support.
Existing quick trade-to product inner tube is to be managed by a peek, and cut hole indentation forms, and zebra guide wire passes through inner tube
Hole and darted section reach a gradient guide elements, by this part, zebra guide wire are drawn inner and outer tubes.Because existing
Inner tube indentation after, easily form the importing obstacle of zebra guide wire, in operation, doctor needs scene to wear zebra guide wire, due to existing
Gradient and part transition, at this moment require to the guiding of gradient part very high, guiding bad, zebra guide wire one often occur
The secondary phenomenon that can not pass inner and outer tubes, therefore often wasting a lot of times passes in zebra guide wire, and misoperation is also simultaneously
The inefficacy of zebra guide wire can be led to.Simultaneously because the particularity of operation, nor put on zebra guide wire in advance, due to operation often
It is to seize every minute and second, if therefore quickly very becoming important technical problem through zebra guide wire.
Content of the invention
Goal of the invention: the technical problem to be solved is for the deficiencies in the prior art, provides a kind of more reliable
Quick exchange inserter.
In order to solve above-mentioned technical problem, the invention discloses a kind of more reliable quick exchange inserter, including outer tube,
One end of outer tube is provided with spike tube, and outer tube is nested with inner tube, and the corresponding position of outer tube and inner tube is provided with gathering sill, extends from gathering sill
Being centrally formed for the passage through zebra guide wire to spike tube, is provided with described passage with diameter greater than described zebra guide wire diameter
Guide pipe, gathering sill is extended in one end of guide pipe.
In the present invention, described guide pipe is the polyimides of polyimide material.
In the present invention, described guide pipe pipe thickness is less than or equal to 0.05mm.
In the present invention, the part that described guide pipe extends gathering sill is provided with removable label.
By original guide elements by being further added by a guide pipe in inner tube, guide pipe adopts new technologic material to the present invention
Elect polyimides (pi) as, thickness of pipe wall is accomplished 0.05mm.There is new structure, guide pipe can ensure zebra guide wire with 100%
Pass from inner and outer tubes.
The present invention quickly exchanges inserter, NiTi braiding biliary tract rack etc. can be put into the human bodies such as gallbladder, pancreas, liver, urethra
In tract, play the effect of drain.The present invention extend to tts intestinal stent inserter, cytology brush, biopsy forcepss, foley's tube,
Papillotome, take stone sacculus and other ercp products.
Beneficial effect: the present invention is guided by dedicated conduits, smoothly can pass inner and outer pipes with 100% guarantee zebra guide wire, reach
Require to quick exchange.The present invention is to be formed with laser engraving because of hypotube, and his concordance and stability can control completely,
Manufacturing is good.Laser engraving figure can be adjusted, thus easily meeting not according to the inserter service condition of different parts simultaneously
Design requirement with position inserter.
Brief description
With reference to the accompanying drawings and detailed description the present invention is done and further illustrate, the present invention's is above-mentioned
And/or otherwise advantage will become apparent.
Fig. 1 is general structure schematic diagram of the present invention.
Fig. 2 is a-a portion partial enlarged drawing in Fig. 1.
Fig. 3 is b-b direction view in Fig. 1.
Fig. 4 is c portion partial enlarged drawing in Fig. 1.
Specific embodiment
As shown in Figure 1 to 4, the invention discloses a kind of more reliable quick exchange inserter, including outer tube 1, outer tube 1
Front end face be provided with spike tube 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, from gathering sill
7 extend to being centrally formed for the passage through zebra guide wire 4 of spike tube 6, are provided with diameter greater than described zebra in described passage
The guide pipe 3 of seal wire diameter, gathering sill 7 is extended in one end of guide pipe 3.Described guide pipe 3 is the polyamides of polyimide material
Imines.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.
Operating procedure of the present invention is as follows:
As shown in Figure 1 to 4:
1st, first part guide pipe 3 is inserted inner tube 2 from outer tube gathering sill 7 before surgery, inner tube 2 and spike tube 6 are stretched out and inserted
Device far-end；Because operation characteristic, zebra guide wire can not be previously threaded through inner tube.
2nd, by zebra guide wire 4, the passage being formed along guide pipe 3 smoothly penetrates from far-end, and the other end passes outer tube 1.?
After be directed to pipe 3 from zebra guide wire near-end extract out, put in recyclable case；
3rd, zebra guide wire is buckled on endoscope's handle proximally by retaining ring, mobile inserter puts into device along zebra
Seal wire is sent into patient and is suffered from body, discharges support, finally puts into device and takes out along zebra guide wire.
The invention provides a kind of more reliable quick exchange inserter, implement method and the approach of this technical scheme
A lot, the above is only the preferred embodiment of the present invention it is noted that coming for those skilled in the art
Say, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
