Description
Technical field
The present invention relates to a kind of adjustable arteria renalis windowing endovascular stent for abdominal aorta systems.
Background technique
Endovascular stent for abdominal aorta is widely used in clinic, energy as the intervention therapeutic apparatus for being directed to abdominal aneurvsm
Effective isolation abdominal aneurvsm and the lesions such as ulcer or interlayer, form fixed alternative pipeline.In clinical use process
In because different sufferer diseased regions difference, and the difference of every patient's arteria renalis aperture position, the especially close arteria renalis and
Kidney mo(u)ld top half abdominal aneurvsm, so that there are certain difficulties for the intracavitary reparation of existing endovascular stent for abdominal aorta, therefore for
Situation needs to customize windowing overlay film frame according to patient's arteria renalis position, but the customization period of this bracket is long, limits treatment
Progress, also increase the financial burden of patient, and its operating procedure is more complicated, very to the technical requirements of doctor
It is high.
Summary of the invention
The present invention proposes that one kind can adjust windowing position on demand in view of the deficiencies of the prior art, enables blood in bracket pipeline
Not further into tumor chamber when flowing in road, the adjustable arteria renalis windowing endovascular stent for abdominal aorta of tumor chamber can effectively be isolated
System.
The purpose of the present invention is achieved by using following technical proposals:
A kind of adjustable arteria renalis windowing endovascular stent for abdominal aorta system, including for being arranged in abdominal aorta and disease
In stove corresponding position and the main support of external overlay film, the main support are provided with non-overlay film in the region where the arteria renalis of left and right
Exposed region, be equipped with releasable, axial length in exposed region position in the main support and be not less than exposed region

Diaphragm area, overlay film region and the first windowing on overlay film region, matching with arteria renalis openings of sizes is set and second is opened
After window, the first windowing overlay film frame and the second windowing overlay film frame discharge in main support, first windowing and second
Open a window it is corresponding with left and right arteria renalis aperture position respectively, and it is described second windowing overlay film frame on non-overlay film region position and
Non- overlay film region position is arranged with the second windowing right in first windowing position correspondence, the first windowing overlay film frame
Answer, it is described first windowing overlay film frame and second windowing overlay film frame overlay film region will be opened on main support except the left and right arteria renalis
The exposed region closing of mouth position.Using the above structure, on the one hand, the partial region of main support is covered with overlay film, the material of overlay film
Matter has good biocompatibility, and blood effectively can be isolated, when blood being enable to flow in bracket pipeline road
Not further into affected area (tumor chamber), affected area can effectively be isolated, on the other hand, pass through the exposed region on main support, energy
Left and right arteria renalis aperture position effectively is avoided, does not interfere the connection of aorta Yu the left and right arteria renalis, avoids blocking blood vessel, again
Have about by the first windowing overlay film frame and the second windowing overlay film frame, extexine circumference that can be discharged in main support
The overlay film region in 1/3 non-overlay film region, outer surface is equipped with windowing corresponding with arteria renalis aperture position, in use, first
The first windowing overlay film frame is placed, the windowing position alignment left renal artery aperture position of the first windowing overlay film frame, non-overlay film are made
Region is arranged in other side right renal artery aperture position, then places the second windowing overlay film frame again, makes the second windowing overlay film branch
The windowing position alignment right renal artery aperture position of frame, the overlay film region of the two, which covers blood vessel and forms substitution, to be led to
Road, to pass through a set of equipment, Ke Yishi in this way for closing in main support except the exposed region of left and right arteria renalis aperture position
Different patients are answered, the progress for the treatment of is accelerated, alleviate the financial burden of patient.
Further, releasable branch overlay film frame is additionally provided in the main support.
Further, the branch overlay film frame is equipped with the independent anchoring device for being fixed on target position.
Further, the first, second windowing overlay film frame opens a window on position in the first windowing and second respectively
Equipped with the positioning identifier that can assist detecting the first windowing and the second windowing orientation by detection device.By positioning identifier, make
Obtaining positioning identifier can develop under x-ray, and such doctor can judge the position and the situation that open a window in vivo according to the positioning identifier,
Guarantee the accurate of operation.
Further, the first windowing overlay film frame and the second windowing overlay film frame are equipped with and can be fixed in main support
, independent anchoring structure.
Further, the outer surface 2/3 of the first windowing overlay film frame and the second windowing overlay film frame is overlay film region,
1/3 is non-overlay film region.The diameter of first windowing and the second windowing is 6-8mm.First windowing overlay film frame and the second windowing are covered
Overlay film hole is aligned according to arteria renalis aperture position, keeps the arteria renalis unobstructed by membrane support rotatably adjustable position before releasing.
Further, the main support, the first windowing overlay film frame and the second windowing overlay film frame by support skeleton and
The overlay film being coated on outside support skeleton is constituted.
In conclusion the present invention it is easy to use, different patients are adapted to by a set of equipment, accelerate treatment into
Degree, significantly reduces the financial burden of patient, is suitable for industrial production.
