Abstract
A kind of kidney fistulation sacculus dilating catheter that this utility model relates to, comprises Connection Block (5), outer tube (4), interior pipe (1), setting sacculus (3) on inner pipe; It is characterized in that: the far-end of described interior pipe (1) is provided with the hard guide wire (2) that one section of distal portion is frustum.This kidney fistulation sacculus dilating catheter, structure is simple, has certain hardness and tapering, adds the most advanced and sophisticated hardness of sacculus dilating catheter, additionally reduce the resistance of sacculus dilating catheter insertion process, can ensure quick insertion puncturing hole.
Description
Technical field
This utility model relates to a kind of sacculus dilating catheter, especially a kind of kidney fistulation sacculus dilating catheter.
Background technology
When clinical medicine carries out the operation of kidney fistulation, need first to carry out renal puncture with puncture needle before expanding, the balloon portion of the sacculus dilating catheter folded by sacculus more afterwards inserts tissue along puncturing hole and arrives kidney.Common common foley's tube is the consistent homogeneity body of front and back caliber, and its caliber is much larger than puncturing hole.Because puncture eye is very little in foley's tube insertion process, and skin, muscular tissue have natural elasticity, have good self-closing function; Therefore more difficult when foley's tube is inserted human body along puncturing hole.
Utility model content
The purpose of the present utility model: aim to provide a kind of sacculus dilating catheter being convenient to insert puncturing hole, solve an above-mentioned difficult problem.
This kidney fistulation sacculus dilating catheter, comprises Connection Block 5, outer tube 4, interior pipe 1, setting sacculus 3 on inner pipe; It is characterized in that: the far-end of described interior pipe 1 is provided with the hard guide wire 2 that one section of distal portion is frustum.
The leading section pipe diameter of described hard guide wire 2 is less than 1.8mm.
The curved transition shape in top of described guide wire.
According to this kidney fistulation sacculus dilating catheter that above technical scheme proposes, structure is simple, has certain hardness and tapering, adds the most advanced and sophisticated hardness of sacculus dilating catheter, additionally reduce the resistance of sacculus dilating catheter insertion process, can ensure quick insertion puncturing hole.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is conical end structural representation of the present utility model;
Fig. 3 is cylinder-shaped end structural representation of the present utility model.
In figure: pipe 2-guide wire 3-sacculus 4-outer tube 5-Connection Block in 1-.
Detailed description of the invention
This kidney fistulation sacculus dilating catheter as shown in the figure, it is the improvement to the existing congenerous kidney fistulation sacculus dilating catheter generally used.
This kidney fistulation sacculus dilating catheter, comprises Connection Block 5, outer tube 4, interior pipe 1, setting sacculus 3 on inner pipe; It is characterized in that: the far-end of described interior pipe 1 is provided with the hard guide wire 2 (see Fig. 2) that one section of distal portion is frustum.
The leading section pipe diameter of described hard guide wire 2 is less than 1.8mm.
As the further genralrlization to technique scheme, with the column shaped horniness pipe (see Fig. 3) in footpath before and after shown guide wire 2 also can adopt.
What propose according to above technical scheme thisly sets up at kidney fistulation sacculus dilating catheter far-end the hard guide wire that one section of distal portion is frustum, especially 1.8mm shape is less than when pipe diameter is made in the end of this section of hard guide wire, due to when the diameter of end is less, material has again certain hardness, when being extremely convenient to expansion, penetrate puncturing hole.Kind of the version of two shown in Fig. 2, Fig. 3 can be taked in actual applications.What wherein Fig. 2 provided is the acute angle form that the top design of far-end one-tenth is less than 90 degree, and what Fig. 3 provided is the shape that end becomes round and smooth cylinder.
Claims (3)
1. a kidney fistulation sacculus dilating catheter, comprises Connection Block (5), outer tube (4), interior pipe (1), setting sacculus (3) on inner pipe; It is characterized in that: the far-end of described interior pipe (1) is provided with the hard guide wire (2) that one section of distal portion is frustum.
2. a kind of kidney fistulation sacculus dilating catheter as claimed in claim 1, is characterized in that: the leading section pipe diameter of described hard guide wire (2) is less than 1.8mm.
