Description
Technical field
This utility model relates near a kind of (trachea hypomere and left and right sides main bronchus, main bronchus and leaf bronchus) pathological changes of treatment big airways branching that is mainly used in, medical apparatus and instruments as narrow, fistula etc. relates to integrated pair of branch of a kind of air flue inner support dedicated transport device specifically.
Background technology
Causing the narrow or fistula of big airways for various good, malignant changes, take interventional radiology air flue inner support placement in the treatment, is one of splendid Therapeutic Method of the curative effect that confirms of Clinical Practice and lot of documents.At present, be widely used in clinical air flue inner support type and be mainly straight tube-like internal metal rack, trachea-main bronchus branching type inner support, and can select full overlay film, part overlay film or bare bracket for use according to cause of disease difference.When in case pathological changes occurring and involving near big airways such as trachea hypomere and bilateral bronchus, main bronchus and the leaf bronchus branching simultaneously, must repeatedly insert the air flue inner support of different size clinically step by step, so not only increase patient's medical expense, increased operation risk and complication rate simultaneously.Integrated pair of branch's inner support of air flue meets the anatomical features of this special diseased region, can be safely, disposable releasing airway constriction or shutoff fistula mouth effectively.Though there is similar Y type Carina tracheae support to come out, can't not insert because of there being feasible stent delivery system, can't apply clinically.
Summary of the invention
The purpose of this utility model provides integrated pair of branch of a kind of air flue inner support dedicated transport device at existing weak point in the above-mentioned technology just.This dedicated transport device is to design according near the anatomical features big airways branching, for inserting of two branches inner support provides a kind of ideal reliable delivery instrument.
The purpose of this utility model can realize by following technique measures:
Integrated pair of branch of air flue of the present utility model inner support dedicated transport device comprises that end is provided with the intermediate layer sleeve pipe of back handle, is sleeved on the support outer layer sleeve that mid-handle on the sleeve pipe of intermediate layer and rear end are provided with front hand grip successively; In the telescopic tube chamber in intermediate layer, be coated with long core pipe, short core pipe, short distractor spool and long traction spool, wherein the end of short distractor spool and long traction spool extends to outside the back handle backward, the front end of long core pipe and short core pipe extends to forward outside the telescopic front port in intermediate layer, on the extension of long core pipe and short core pipe, be set with two branches inner support, be separately installed with spindle big soft head and the spindle little soft head that expands that expands at the front end of long core pipe and short core pipe, the tube chamber of described long core pipe and weak point core pipe is that seal wire installs the chamber; In the tube chamber of short distractor spool and long traction spool, be coated with a binding silk thread respectively, the rear and front end of binding silk thread all extends to outside the tube chamber of short distractor spool and long traction spool, and the preceding extended end of two binding silk threads combines with the overhanging end of long core pipe and short core pipe respectively; Front hand grip is provided with the logical oxygen hose with support outer layer sleeve intracavity inter-connection.
This utility model is set with the conical ring locating part that matches with front hand grip and mid-handle rear end face respectively on the sleeve pipe of intermediate layer; The preceding extended end of two binding silk threads combines with the overhanging end of long core pipe and short core pipe respectively by rubber grommet; The front port place of support outer layer sleeve is provided with the metal marker ring.
After the extension of long core pipe described in this utility model and short core pipe passes and adopts elastic metallic yarn to weave two branches inner support major network tube chamber of the bifurcation font network management framework that forms, from the cavity of left and right two branch's webmasters, pass respectively, and the spindle that is separately positioned on long core pipe and short core tube end big soft head and the spindle little soft head that expands that expands all is positioned at the front end of pair left and right two branch's webmasters of branch's inner support.That the described pair of branch's inner support has is wear-resisting, corrosion resistance and fabulous histocompatibility, and the fenestral fabric unit has better elastic, scalability, vertically pliability and radial support power uniformly, and the support shape can change with temperature.
The size of described pair of branch's inner support is by the individuation design.Usually, about the l0%-20% of shelf inner diameter greater than inserting position air flue internal diameter, stent length is advisable to surpass pathological changes 5-10mm.Front end at major network pipe lateral ends, bifurcation and left and right two branch's webmasters of two branches inner support respectively has a metal marker, so that accurately locate, discharge under the X line.Integrated pair of branch's inner support of air flue can be controlled pathological changes around the big airways branching effectively, as expanding narrow section, thorough shutoff fistula mouth well, and phenomenons such as support displacement, a plurality of support juxtapositions takes place seldom, can guarantee airway unobstructed.
The beneficial effects of the utility model are as follows:
1. pathological changes can disposablely be inserted the two branches of one piece of air flue inner support near the big airways branching, thoroughly solves near the narrow or fistula of branching in air flue many places, has lowered surgery cost, risk and complication, has shortened operating time;
2. integrated pair of branch's inner support of air flue is lower than straight tube-like, single branch-like inner support displacement rate;
3. integrated pair of branch of air flue inner support dedicated transport device can remain airway patency, and is little to the pulmonary ventilation influence;
