Abstract
The utility model discloses a single-branched stent for surgical operation, which is characterized in that a stitching rim section serving as a close section is connected with a flexible metal stent, a single-branched blood vessel bypass is arranged on the stitching rim section, and the metal stent is covered by stent mulch. The single-branched stent is advantageous in that: 1, stitching between an artificial blood vessel and an artery under clavicle can be avoided. Since such a deep position may cause stitching difficulties, blood leakage after stitching and difficulty in complementary stitching, the stent simplifies an operational process, and reduces deep hypothermic circulation arrest (DHCA) time during the operation and complications resulted from extracorporeal circulation (CPB) and DHCA. Eliminating stitching between an artificial blood vessel and the aorta reduces the possibility of hemorrhage and the risk of an operation. 2, Stent elephant trunk blood vessel has excellent attaching performance. Having self-dilatancy, the stent enables the reattachment of separated aortic wall. 3, Moreover, the stent has excellent hemodynamic effects, and can effectively enlarge true lumen and improve blood supply for internal organs.
Description
Technical field
This utility model relates in a kind of art of Stanford A type dissection of aorta uses overlay film frame, is used for closed distal end interlayer blood vessel, and rebuilds tremulous pulse under the left collarbone simultaneously.
Background technology
Dissection of aorta is one of the most dangerous disease of cardiovascular surgery, and with the mortality rate height, the treatment difficulty is big, and postoperative complication is many, and therapeutic effect is not good enough to be celebrated.Particularly complexity (C type) dissection of aorta extent of disease is wide, often involve important big bifurcated artery, as innominate artery, common carotid artery, internal organs trunk etc., easily cause the perfusion of patient's nervous system and internal organs bad, even cause serious consequences such as apoplexy, paraplegia, internal organs ischemia necrosis, limb ischemia necrosis, shock and death.Internal medicine conservative treatment is to C type dissection of aorta patient unsatisfactory curative effect, therefore should disease one timely operative treatment after diagnosing.
Operation means commonly used at present are to use the operation of full support terylene trunk blood vessel, this operation is applicable to most C type dissection of aorta pathological changes, comprises the Stanford Type B interlayer of Stanford AC type interlayer, Stanford BC type interlayer and interventional therapy failure.
But this art formula shortcoming is to operate still complexity, still needs out breast, hypothermia, stops operations such as circulation, selective cerebral perfusion, and wound and operation untoward reaction are still bigger than normal.Simultaneously, this overlay film frame is made up of overlay film and metal rack, and metal rack forms the hollow circular cylinder of a network, and overlay film is wrapped on the metal support surface.During treatment, this overlay film frame compression is implanted in the descending aorta, discharges then to get final product.But there are some shortcomings in this overlay film frame: 1 tinsel too high levels, and 2 overlay film frame integral body are too stiff, and 3 overlay films are blocked up, compression back volume is excessive, may cause luminal stenosis simultaneously, 4 not gradually carefully designs, can cause the descending aorta expansion long term, even the New Development cut.And the art medium-height trestle mainly relies on Microport Medical Corp and produces support, and every piece of support quotation is above 10,000 yuan.
Summary of the invention
The purpose of this utility model provides in the aorta art and uses overlay film frame, makes operation technique simple, and open condition is put down in the art, and easy operating is sewed up.
In order to achieve the above object, the technical solution of the utility model has provided single branch support in a kind of art, it is characterized in that: as the sutural margin section of near-end, the sutural margin section links to each other with the metal rack with good compliance, on the sutural margin section, be provided with single branch vessel bypass, be wrapped with the support overlay film at metal rack.
Described support overlay film is an artificial blood vessel.
The utility model has the advantages that: 1, avoided the stitching of artificial blood vessel and left subclavian artery,, sewed up difficulty herein, sewed up the back and leak blood easily, be difficult for mending pin because the position is darker.This support is simplified operation process, has shortened profound hypothermia in the whole surgery, has stopped the circulation time, reduces complication due to extracorporeal circulation and the Deep Hypothermia Circulatory Arrest; Save ramose coincideing of artificial blood vessel and aortic arch, reduced hemorrhage probability, reduced the risk of operation.2, support trunk blood vessel attaching property is good, owing to have self-expanding, isolating aorta wall is attached again.3, have good hemodynamic Effects, enlarge true chamber effectively, heart blood supply in improving.
Description of drawings
The structure chart of single branch support in a kind of art that Fig. 1 provides for this utility model;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
Specify this utility model below in conjunction with embodiment.
As shown in Figures 1 and 2, single branch support in a kind of art that provides for this utility model, comprise sutural margin section 2 as nearly section, sutural margin section 2 links to each other with the metal rack 1 with good compliance, on sutural margin section 2, be provided with single branch vessel bypass 3, be wrapped with support overlay film 4 at metal rack 1, support overlay film 4 is slim artificial blood vessel.It is flexible structure that single branch vessel bypass 3 connects sutural margin section 2 places.
Mount proximal end has single branch vessel bypass 3, is used for single branch vessel far-end and fills in left subclavian artery, avoids complicated stitching.Mount proximal end inside does not comprise the support composition, reinforces aorta wall with interrupted suture, eliminates false chamber, and convenient identical with the nearly section of ascending aorta.The far-end overlay film frame has better pliability, and is adherent functional, and tinsel all is wrapped in artificial overlay film inside, the aortic aneurysm wall do not produced bigger compressing.
Use the operation process of this support to be: 1, conventional free right axillary artery and an arm blood vessel 3 big branches; 2, set up right axillary artery---the body of right atrium outer circulation; 3, the change of active proximal disorders of meridian is handled in cooling simultaneously; 4, selective cerebral perfusion is carried out by the right axillary artery intubate in the cooling back, inserts support trunk blood vessel at the aortic arch far-end; 5, descending aorta near-end and remain two branches and coincide; 6, recovery temperature and perfusion; 7, coincide with the active proximal arteries and veins, operation is finished.
Claims (2)
1. single branch support in the art, it is characterized in that: as the sutural margin section (2) of near-end, sutural margin section (2) links to each other with metal rack (1), is provided with single branch vessel bypass (3) on sutural margin section (2), is wrapped with support overlay film (4) at metal rack (1).
2. single branch support in a kind of art as claimed in claim 1 is characterized in that: described support overlay film (4) is an artificial blood vessel.
