Abstract
The utility model discloses a rapid exchange inserter with a more reliable hypo tube, which comprises an outer tube, a tip tube is arranged at one end of the outer tube, a front handle is arranged at the other end of the outer tube, an inner tube is nested into the outer tube, the hypo tube is nested into the inside of the inner tube, a guide groove is formed in the corresponding part of the outer tube, the inner tube and the hypo tube, a channel penetrating through a zebra guide wire is formed in a position extending from the guide groove to the center of the tip tube, a guide tube of which the diameter is larger than that of the zebra guide wire is arranged in the channel, and one end of the guide tube extends out of the guide groove. The rapid exchange inserter has the benefits that as the special guide tube is used for guide, the zebra guide wire can be completely enabled to penetrate out the inner tube and the outer tube so as to meet the rapid exchange requirement; as the hypo tube of the rapid exchange inserter is formed by laser engraving, the consistency and the stability of the hypo tube can be completely controlled, therefore, the manufacturability is good; moreover, laser engraving graphics can be adjusted according to the use situations of inserters at different parts, so that the design requirements of the inserters at different parts are easily met. In addition, a tail end has an infusion function.
Description
Technical field
This utility model relates to the more reliable hypotube of a kind of medical inserter device, particularly one and exchanges fast 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 the more reliable hypotube of one to exchange fast inserter.
In order to solve the problems of the technologies described above, the utility model discloses the more reliable hypotube of one and exchange fast inserter, comprise outer tube, one end of outer tube is provided with point pipe, the other end is provided with front hand grip, outer tube is nested with inner tube, inner tube nested inside hypotube, the corresponding position of outer tube, inner tube and hypotube is provided with gathering sill, extend to Jian Guan center from gathering sill and be formed for the passage through zebra seal wire, 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.
The pipe thickness of guide pipe described in this utility model is less than or equal to 0.05mm.
By original guide elements, by increasing a guide pipe in inner tube, guide pipe adopts new technologic material to elect polyimides (PI) as, and thickness of pipe wall is accomplished to 0.05mm again.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, because leading 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.Tail end is supported infusion function simultaneously.
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.
Fig. 1 is this utility model population structure schematic diagram.

Detailed description of the invention
As shown in Figure 1 to 4, the utility model discloses the more reliable hypotube of one and exchange fast inserter, comprise outer tube, outer tube is by front hand grip connecting portion 9, afterbody 8, middle part 7 and anterior 5 forms, the end face of outer tube front portion 5 is provided with point pipe 3, the handle connecting portion 9 of outer tube is provided with front hand grip 10, outer tube is nested with inner tube 2, inner tube 2 nested inside hypotube 1, outer tube middle part 7, the corresponding position of inner tube 2 and hypotube 1 is provided with gathering sill 11, the center that extends to point pipe 3 from gathering sill 11 is formed for the passage through zebra seal wire 6, in described passage, be provided with the guide pipe 4 that diameter is greater than described zebra seal wire diameter, gathering sill 11 is extended in one end of guide pipe 4.The polyimides that described guide pipe 4 is polyimide material.The pipe thickness of guide pipe 4 is less than or equal to 0.05mm.
This utility model operating procedure is as follows:
As shown in Figure 1 to 4:
1, before operation, first part guide pipe 4 is inserted to inner tube 2 from outer tube gathering sill 11, through hypotube 1, inner tube 2 and point pipe 3 stretch out inserter far-end; Because operation characteristic, zebra seal wire can not pass inner tube in advance.
2, by zebra seal wire 6, the passage forming along guide pipe 4 penetrates from far-end smoothly, and the other end passes outer tube.Finally guide pipe 4 is extracted out from zebra seal wire near-end, put into recyclable case;
