Description
Technical field
It is specially a kind of for bile duct drainage and the fixable type branch of flushing the utility model relates to medical instruments field
Frame nose bile duct.
Background technique
Endoscopic naso-biliary drainage (ENBD) is the bile duct drainage decompression technology implemented under duodenoscope direct-view.
ENBD has as a minimally-invasive treatment technology and releases obstruction of biliary tract rapidly, reduce pressure of biliary tract, adequate drainage, rinse cleaning
The effect of biliary tract, is widely used in clinic.Current clinically conventional use of drainage tube is that tail end-side cornice has the thin of conduction hole
Tubular structure has the following problems: 1, because wing of nose two sides skin secretion is more, adhesive plaster and skin paste injustice, and drainage tube
Official jargon is thinner, when patient's changing position or out-of-bed activity, easily pulls out nose bile duct.2, it often will appear drainage not during patient
Freely, pipe phenomenon is hindered, need to be intubated again.3, nose bile duct flushing can keep draining unobstructed, and effectively treat pyogenic cholangitis
The effective measures of equal infectious diseases, but rinse excessive velocities or pressure is excessive that biliary pressure is caused to increase suddenly, it can cause
Patient is uncomfortable, the adverse consequences such as retrograde infection or toxaemia occur.
Summary of the invention
The purpose of this utility model is that disclosing a kind of improvement tradition in view of the above-mentioned problems, overcome the shortage of prior art
Nose bile duct easily deviates from, inadequate drainage and by flushing speed and the improper fixable type bracket nose bile duct for leading to complication of amount.
To achieve the above object, the utility model uses following technical scheme:
It is a kind of for bile duct drainage and the fixable type bracket nose bile duct of flushing, including drainage tube and bracket are described to draw
Flow tube tail end side wall offers drainage tube conduction hole, and seal wire, bracket card slot and stand tube inner segment are equipped in the drainage tube, described
Bracket be can the rounded self-expanding stent of bracing type and section, the bracket be equipped with stent drainage hole, the stent drainage hole
Aperture is consistent with the drainage tube aperture.
Preferably, the stand tube inner end is fixed after bracket release with card slot.
Preferably, the drainage tube is hollow tube and section is rounded.
Preferably, the support skeleton is nitinol alloy wire, and it can position under x-ray while can be covered with medicine outside it
Object coating, the bracket are self-expanding stent, have distraction force in traditional thread binding, and when it removes external distraction force restores original shape
State.
Preferably, the drainage pipe diameter of the bracket upper opening is consistent with drainage bore.
Preferably, the bracket is with drainage tube conduction hole segment length and less than 6cm.
Preferably, segment length is slightly longer than drainage tube after bracket discharges completely and drains hole section in the stand tube, and can lead to
Cross locating support clear drainage tube drainage hole site.
The utility model has the following beneficial effects: fixable type bracket nose bile duct end can bracing type self-expanding stent can be according to
Fixed nose bile duct can be assisted by the characteristic of its rough surface and elastic dilatation, it is longer to alleviate the nose bile duct merging time to a certain extent
The pore size of the probability that Shi Rongyi is drawn out with patient's changing position or out-of-bed activity, bracket is consistent with drainage bore, can
Inadequate drainage even plugging caused by the substances such as choledochus liner mud blocking nose bile duct in drainage process is prevented, scope again is needed again
The case where underlying pipe.Bracket upper-side hole opening and drainage tube dislocation out of shape simultaneously, can buffer the flushing liquor in injection nose bile duct, have
Effect reduce because rinse excessive velocities or pressure is excessive cause biliary pressure to increase suddenly caused by patient discomfort and retrograde infection or
The serious adverse consequences such as toxaemia.

Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Embodiment 1:
As shown in figures 1 to 6 a kind of is for bile duct drainage and 3 nose bile duct of fixable type bracket of flushing, including drainage tube
2 and bracket 3,2 tail end side wall of drainage tube offers drainage tube conduction hole 5, and seal wire 1, bracket card slot 7 and branch are equipped in drainage tube 2
Frame pipe inner segment 6, bracket 3 be can the rounded self-expanding stent 3 of bracing type and section, bracket 3 be equipped with stent drainage hole 4, bracket
4 aperture of conduction hole is consistent with 2 aperture of drainage tube.Stand tube inner segment 6 is fixed with card slot 7 after the release of bracket 3, prevents bracket
3 further releases.Drainage tube 2 is hollow tube and section is rounded.3 skeleton of bracket is nitinol alloy wire, convenient in merging process
Middle positioning, the coarse apertured elastic dense matter of mantle surface, and it can position under x-ray while can be covered with drug outside it
Coating, bracket 3 are self-expanding stent 3, have distraction force in traditional thread binding, and when it removes external distraction force restores reset condition.Branch
2 diameter of drainage tube of 3 upper opening of frame is consistent with 2 internal diameter of drainage tube, and the substances such as cholelith in choledochus, gallbladder mud is avoided to block up nose bile duct
Plug.Bracket 3 is with 5 segment length of drainage tube conduction hole and less than 6cm.6 length of stand tube inner segment is slightly longer than after bracket 3 completely release
5 sections of drainage tube conduction hole, and clear 5 position of drainage tube conduction hole of locating support 3 can be passed through.
When Endoscopic nasobiliary drainage, after the merging in place of 3 nose bile duct of this fixable type bracket, branch is strutted with seal wire 1
Frame 3 fixes the head end of nose bile duct, realizes the effect for releasing obstruction of biliary tract rapidly, reducing pressure of biliary tract.
Embodiment 2:
Compared with Example 1, the difference of the present embodiment 2 place is that stent drainage hole 4 is not in the drainage tube of nose bile duct 2
Straight line, length of the stand tube inner segment 6 after bracket 3 completely release are slightly longer than 5 sections of drainage tube conduction hole, can pass through positioning branch
The position of the clear drainage tube conduction hole 5 of frame 3.After nose bile duct merging is in place, in order to realize the adequate drainage of nose bile duct, and treatment
The infectious diseases such as purulence cholangitis need to be rinsed nose bile duct drainage, can inject rinse from the head end of drainage tube 2 at this time
Liquid, then aspirate, the effect effectively realized nose bile duct adequate drainage, rinse cleaning biliary tract.
The utility model effect reduce because rinse excessive velocities or pressure is excessive cause biliary pressure to increase suddenly caused by patient
The uncomfortable and serious adverse consequences such as retrograde infection or toxaemia.
Above-described embodiment, the only preferred embodiment of the utility model are not used to limit the utility model practical range,
Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model should all be included in
Within enclosing.
