Description
Technical field
The present invention relates to field of medical technology, take off biliary stent more particularly, to a kind of anti-work of sacculus.
Background technique
There are many surgical drainage tube type clinically applied, and some is used for urethral catheterization, and some is used for wound, thoracic cavity, encephalocoele, stomach
Enteron aisle, biliary tract etc. have application;Surgical drainage is in order that the purulence, blood, liquid that gather between tissue or in body cavity are directed to
In vitro, it prevents postoperative infection and influences wound healing.
Currently, traditional biliary stent is linear type, front opening collects bile;Slip in order to prevent, it is general using at
Loop technology;Be provided with a filament in conduit, after conduit delivery location, tension filament is bent in front of conduit, generally in
Existing annular reduces the probability of slippage so fixed function is played in front end.
However its there are problems: biliary tract be it is linear, front end necessarily compresses and rubs against biliary tract composition at loop, especially head end
When movement, compresses and rubs against and be unfavorable for biliary tract function of patients recovery;It not can effectively prevent bile at loop technology and enter abdomen along puncture path
Chamber easily causes peritonitis;And at loop technology not can effectively prevent drainage tube slip, will cause set again pipe to patient spend and
Second operation pain causes the excessive initiation severe complication of bile with biliary tract is torn, is unfavorable for the recovery of puncture path;Simultaneously at loop
Often there is drainage tube displacement in technology, leads to inadequate drainage, and second operation tune pipe increases patient suffering and cost;At loop technology
Drainage tube needs to unlock loop when extracting, and needs to operate below ray, increases ray exposure duration, simultaneously because for a long time at loop,
It is larger to unlock loop difficulty for deformation of guide tube, and increases above-mentioned risk.
Summary of the invention
The present invention proposes that a kind of anti-work of sacculus takes off biliary stent, to solve the problems, such as to mention in above-mentioned background technique.
The technical scheme of the present invention is realized as follows:
A kind of de- biliary stent of the anti-work of sacculus comprising biliary drainage pipe and the filling being set in outside biliary drainage pipe
Pipe;Biliary drainage pipe is the three stage structure of connection, and wherein the diameter of second segment pipe is less than the diameter and third section of first segment pipe
The diameter of pipe, first segment pipe and second segment pipe are in arc transition, are provided with angle structure between second segment pipe and third section pipe;It fills out
It fills pipe sleeve to be located on second segment pipe, the end of the close first segment pipe for filling pipe and second segment pipe junction is arranged to flexible ball
Capsule, offers an opening on the filling pipe at angle structure, and third Duan Guancong opening set is pierced by filling pipe, first segment pipe
Head surrounding be provided with and be equipped with several through-holes.
Further, the duct thickness of second segment pipe and hardness are all larger than filling pipe.
Further, flexible ball is intracapsular is filled with radionuclide.
Further, the diameter of first segment pipe is gradually reduced by first segment pipe and junction to the head of second segment pipe, the
Drops is set as at the head top of one section of pipe.
Further, the duct thickness of second segment pipe is 2 times for filling pipeline thickness;Optionally, the pipe of second segment pipe
Road hardness is 5-8 times for filling pipeline hardness.
Further, the tail end of third section pipe is connected with a depression drainage device, and the free end for filling pipe is connected with an air valve.
Further, air valve includes the pedestal with opening, is configured to that the opening of pedestal can be buckled into and seals the opening, tool
There is the check valve pedestal of air inlet, is configured to the piston that can be buckled into the air inlet of check valve pedestal and seal the air inlet;Wherein
Pass through connection band connection between pedestal and check valve pedestal, between check valve pedestal and piston, nonreturn valve core is located at unidirectional valve base
It is fixed in seat and by unidirectional fixed core.
Further, biliary drainage pipe and filling pipe integrated injection molding.
Further, the diameter of second segment pipe is the one third of first segment pipe diameter, and the diameter of second segment pipe is third
The half of section pipe diameter.
Using above-mentioned technical proposal, the invention has the benefit that
The anti-work of the sacculus takes off the front end of biliary stent using flexible sacculus extended technology, can effectively prevent bile along puncture
Road adverse current enters abdominal cavity, and anti-slip effect is better than not needing to complete under ray at loop, when pulling out, and surgical procedure is simple when pulling out, and suffers from
Person's pain is small;And flexible ball is intracapsular can be filled with radionuclide, flexible ball is intracapsular to be filled with radionuclide, can kill gallbladder
The tumour cell of road wall, normal tissue damage are smaller.
When in use, first the intracapsular gas of flexible ball or water are discharged at air valve, then the head of first segment pipe is slow
Insertion human body drain site, to the intracapsular inflation of flexible ball or water, make its expansion when being inserted into predetermined position, play fixed make
With carrying out biliary drainage by depression drainage device later;After, the intracapsular gas of flexible ball or water are extracted out, this is taken out and draws
Flow tube.
