Abstract
The utility model relates to a membrane-covered stent which comprises a main body membrane-covered part, a bare stent I part and a bare stent II part. The main membrane-covered part, the bare stent I part and the bare stent II part are connected into a whole. The bare stent I part and the bare stent II part are respectively arranged on the two end sides of the main body membrane-covered part. The bare stent II part is of a fine-mesh structure and made of self-expanding type metal wires. A radial support force of the bare stent II part is larger than a radial support force of the main body membrane-covered part. The membrane-covered stent can effectively closure an endangium rupture and effectively shape a blood vessel true lumen, and meanwhile attachment of the main body membrane-covered part and a blood vessel wall can be also increased. Surgery time can be shortened.
Description
Technical field
This utility model relates to the medical apparatus and instruments that a kind of Wicresoft gets involved, and refers to especially a kind of overlay film frame.
Background technology
Developing rapidly along with the endoluminal vascular surgery in recent years, dissection of aorta intracavity recovery technique has become the primary treatment measure for Stamford (Stanford) Type B dissection of aorta, compare with the surgical operation therapy that tradition is open, it is little to have wound, Peri operative mortality and complication rate are low, and the patient recovers the advantage such as fast.
The blood vessel covered stent that uses at present generally adopts the overlay film Design of length of 120-180mm, this design on the one hand can effectively shutoff Human Thoracic Aortic Dissection the first cut, can prevent again in addition the shutoff of breast 8-12 cone plane intercostal arteries, reduce the risk that causes paraplegia.But larger for some false chambeies, true chamber pressurized is obvious, the case of spinal cord or abdominal viscera blood supply disorder perhaps occurred, and the support that often needs more to grow struts compressed true chamber and guarantees the blood supply of abdominal viscera and lower limb.For above-mentioned problem, adopt clinically at the overlay film frame far-end and place again a self-expansion type bare bracket, although this mode can guarantee the effective expansion to the true chamber of blood vessel, prevented intercostal arteries, coeliac trunk, the shutoff of the branch vessel such as renal artery, reduced the secondary injury of overlay film frame far-end to blood vessel wall, but because this technology need to make when using and have between overlay film frame and the bare bracket that 20mm's roughly is overlapping, and can cause owing to the excessive danger that insecondary blood vessel injury occurs of the supporting force of lap, and this mode can prolong operating time.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of overlay film frame, this overlay film frame has been avoided the Secondary cases blood vessel injury that causes owing to the support force of support lap is excessive under the prerequisite that can guarantee the effective plasticity in true chamber to blood vessel, shortened simultaneously operating time.
The overlay film frame that this utility model provides, comprise main body overlay film section, bare bracket I section and bare bracket II section, described main body overlay film section and described bare bracket I section, described bare bracket II section connect as one, and it is distolateral that described bare bracket I section and described bare bracket II section are positioned at respectively two of described main body overlay film section.
In said structure, main body overlay film section can effectively shutoff tunica intima cut, the bare bracket part can be carried out the true chamber of blood vessel effectively moulding, and increased the attaching of main body overlay film section and blood vessel wall, again since bare bracket part be connected with main body overlay film section one, therefore the seriality to the support force in the true chamber of blood vessel can be guaranteed, and operating time can be shortened.
This utility model is preferred, and described bare bracket II section is the polybrochate structure.
This utility model is preferred, and described bare bracket II section is made of the self-inflated tinsel.
This utility model is preferred, and the radial support power of described bare bracket II section is greater than the radial support power of described main body overlay film section.
This utility model is preferred, and described main body overlay film section is sewn on the zigzag nitinol alloy wire by dacron membrane and consists of.
This utility model is preferred, and described bare bracket I section is braiding structure.
Overlay film frame of the present utility model, by the two ends in main body overlay film section the bare bracket that connects as one with it is set, can effectively shutoff tunica intima cut and the true chamber of blood vessel carried out effectively moulding the time, also can increase the attaching of main body overlay film section and blood vessel wall, and can shorten operating time.
Description of drawings
Fig. 1 represents the structural representation of collateral covered graft-stent.
[description of symbols among the figure]
1: overlay film frame; 10: main body overlay film section; 20: bare bracket I section; 30 bare bracket II sections.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated.Fig. 1 is the structural representation of overlay film frame of the present utility model, and this overlay film frame 1 integral body is tubular shape, comprises main body overlay film section 10, bare bracket I section 20 and bare bracket II section 30.
Bare bracket I section 20 connects the head end side (left side among the figure) that is arranged on main body overlay film section 10, bare bracket II section 30 connects the tail end-side (right side among the figure) that is arranged on main body overlay film section 10, main body overlay film section 10 keeps thoracic aorta covered bracket structure commonly used at present, namely, be sewn on the zigzag nitinol alloy wire by dacron membrane and consist of, bare bracket I section 20 is identical with the bare bracket of the head end side of the overlay film frame of commonly using, and is zigzag or braiding structure, is used for the conveying of overlay film frame 1.
Bare bracket II section 30 consists of the polybrochate structure by the self-inflated tinsel, can weave for nitinol alloy wire, also can adopt the stainless steel laser engraving technology, cancellated mesh diameter is for example between the 0.5-10mm, bare bracket II section 30 is connected with the tinsel of main body overlay film section 10, according to the position of using and patient's difference, overlay film frame 1 can be arranged to different models and have different diameters and length, in addition, the radial support power that the radial support power of bare bracket II section 30 is a bit larger tham the tail end-side of main body overlay film section 10 is set, to increase the attaching of overlay film frame tail end and blood vessel wall.
When this overlay film frame 1 is carried out releasing operation, at first with the carrier of packing into after overlay film frame 1 compression, then this conveyer device is sent in the blood vessel to be repaired and positioned, recession epitheca pipe makes the main body overlay film section 10 of overlay film frame 1 and the bare bracket part successively discharges and the attaching blood vessel wall, withdraws from carrier.
The above only is preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
