Description

A kind of liver inside door-vena systemica shunting bracket
Technical field
The present invention relates to field of medical technology, specially a kind of liver inside door-vena systemica shunts bracket.
Background technique
Currently, bracket used in TIPS art is divided into bare bracket and overlay film frame.Bare bracket is due to postoperative high speed blood flow Stimulation causes false inner membrance to be formed, and easily causes runner restenosis;Overlay film frame can greatly prolong the patency of runner, but Bracket easily influences portal venous flow after entering portal vein;And easily there is " nut cap " phenomenon in bracket both ends.Existing overlay film frame is uncomfortable Close the needs that liver inside door-vena systemica precisely shunts.And the latus rectum inside overlay film frame in the prior art is fixed, in liver Door-vena systemica needs the case where often adjusting intravenous flow rate to be difficult to meet, in consideration of it, it is proposed that a kind of liver inside door-vena systemica Shunt bracket.
Summary of the invention
The purpose of the present invention is to provide a kind of liver inside door-vena systemicas to shunt bracket, to solve to mention in above-mentioned background technique Overlay film frame out be not suitable for that liver inside door-vena systemica precisely shunts the problem of needs.
To achieve the above object, the invention provides the following technical scheme:
A kind of liver inside door-vena systemica shunting bracket, including interior overlay film in a tubular form, one end of the interior overlay film is expanded outwardly Overlay film flaring, is closely fitted with one layer of outer metal mesh, one end of the outer metal mesh on the outer wall of the interior overlay film in being formed It expands outwardly to form metal mesh flaring apterium, is flared apterium in the metal mesh and the junction of the interior overlay film flared end is set There are several metal balls;
It is symmetrically arranged with two fixture blocks on the other end inner wall of the interior overlay film, adjusting group is equipped between two fixture blocks Part, the interior grid for adjusting component and including outer grid and being embedded inside the outer grid.
Preferably, each fixture block offers square groove close to the side for adjusting component, in the square groove Two sides inner wall on be equipped with one group of arc metal plate, two groups of arc metal plates are symmetrical, and arc metal plate described in every group The quantity being equipped with is two.
Preferably, card slot there are two radially symmetrically being opened up on the side wall of the outer grid, the inner end of each card slot Convex block is equipped on wall.
Preferably, the card slot and the fixture block are mating, and the convex block and the square groove are mating, and each institute Convex block is stated to be connected between two arc metal plates ipsilateral with it.
Preferably, the surface of the outer grid equidistantly offers several fan-shaped through slots in a ring, in the outer grid Inside offers the frame trough with the interior grid rotation connection.
Preferably, the surface of the interior grid be equipped with several fan shape baffles, the number and shape of the fan shape baffle with The sector through slot is corresponding.
Preferably, it is also coaxially connected with rotation axis at the center of the interior grid, is radially offered in the rotation axis By its completely through straight trough mouth.
Preferably, the quantity of the metal ball is at least four, and equidistantly distributed in a ring.
Compared with prior art, beneficial effects of the present invention are as follows:
1, the present invention is by expanding one end (portal vein end) opening portion of overlay film frame in " horn mouth " sample, expansion section Divide and four metal marker points used to demarcate as overlay film part and metal mesh part, fits closely bracket with portal vein tube wall, The influence of blood flow of venous shunt distal end on the door is utmostly reduced, the regeneration of bracket inner tissue is reduced, prevents stent occlusion and " lid Cap " (the vena hepatica end or portal vein end of bracket are covered by vascular wall) phenomenon, and bracket can be accurately positioned at DSA, it is suitble to Accurate liver inside door-vena systemica bypass of accurate liver inside door-left branch of vena systemica bypass, especially trans-portal vein.
2, the present invention increase quick detachable adjusting component by the other end to overlay film frame, by adjust fan shape baffle with The overlapping area of fan-shaped through slot adjusts the latus rectum of overlay film frame, and then adjusts flow velocity, simple to operate, in some special feelings No replacement is required when needing that the flow and flow velocity of overlay film frame is adjusted under shape overlay film frame, significantly to the physical impairment of patient It reduces.
