The self-elastic type stent supporting body (2) comprises a main body part and a branch part located at a side edge of the main body part, wherein the branch part of the stent supporting body is integrated through an implantable medical alloy (such as super-elastic nichrome and the like) tube in a laser engraving way.
Description
Technical field
This utility model relates to a kind of art medium-height trestle, and branch's overlay film frame in particularly a kind of art is used for the surgical operation therapy of dissecting aneurysm of aorta.
Background technology
The sickness rate of dissecting aneurysm of aorta is that annual every million people's mouth is about 5～10 examples, and M-F is about 3: 1, and the onset peak age is 50～60 years old.58% death is arranged in 24 hours in the acute dissecting aneurysm case without suitably treatment, only have 30～35% patient can excessively be chronic phase.And the aorta wall tissue of dissecting aneurysm case is fragile, is prone to fragmentation, and the operation technique difficulty is big, and mortality rate is high.
In existing medical skill; It is a progress greatly of aortic surgery in recent years that overlay film frame is used to treat dissection of aorta; This technology is to utilize the aortic arch and the branch vessel of three ramose artificial blood vessel 10 replacement pathological changes; Through the otch of descending aorta, overlay film frame 20 is implanted descending aorta again.Support can flick voluntarily, with the sealing dissection of aorta.At last, overlay film frame and artificial blood vessel are stitched together, as shown in Figure 1, wherein the suture site is denoted as 30.This technology can reduce the required secondary side open chest surgery of traditional surgery.But this operation still needs further to improve, because in operation process, need carry out three branch artificial blood vessels and the people stitching from the body blood vessel, and time-consuming of institute is longer.In addition, Deep Hypothermia Circulatory Arrest is prone to cause various postoperative complications for a long time, and has the hemorrhage problem of stitch points, and this is one of reason that causes patient's postoperative death.
Because the length of operating time is the successful significant impact factor of operation, therefore needs to use a kind of implantable stent of closed sandwich fast.Proposed improved branch overlay film frame, it needn't sew up branch in art for this reason, only needs to cut off in proximal aorta; Through otch branch's overlay film frame is inserted, the interlayer of disposable each blood vessel of sealing, and keep vascular patency; Make the vascular suture mouth be reduced to 1 thus, reduced the stitch points risk of bleeding simultaneously, and the probability of happening of complication is reduced greatly; As shown in Figure 2, wherein 20 ' is improved branch of the prior art overlay film frame, and 30 ' is the suture site.
The Chinese invention patent CN200510028616.0 that on August 9th, 2005 submitted to discloses a kind of aforesaid improved art medium-height trestle prosthese and carrier; Its art medium-height trestle prosthese comprises artificial blood vessel prosthese and eject intravascular stent; Said eject support is fixedly installed in the artificial blood vessel prosthese; The outer wall of eject support contacts with the inwall of artificial blood vessel prosthese; One end end of said artificial blood vessel prosthese is longer than the corresponding end of eject support, also can be the silk binding type carrier and its carrier can be a sheath tubular type carrier.The support prosthese of this patent is used for aortic aneurysm and becomes surgical operation, is specially adapted to treat the aortic disease that can not touch from surgical openings in the operation.The artificial blood vessel prosthese that the art medium-height trestle prosthese of this patent can be used with general surgery is sewed up, also can with the vascular suture of human body self, thereby enlarged field of operation, the operation of traditional twice completion of need can once be accomplished, improved operation efficient.
The Chinese utility model patent CN200620137903.5 that on JIUYUE 27th, 2006 submitted to also discloses a kind of aforesaid aortic arch three side support blood vessels; It comprises the aortic stents blood vessel; Said aortic stents blood vessel is divided into ascending aortic segment, aortic arch section and descending aorta section; It also comprises three collateral artery support blood vessels; Said three collateral artery support blood vessels are separately fixed on the arc-shaped surface of aortic stents blood vessel aortic arch section, and constitute the five-way type, and said three collateral artery support blood vessels are distinguished innominate artery, LCC and left subclavian artery on the corresponding aortic arch successively.This patent can make operation process greatly simplify, and has shortened the time of Deep Hypothermia Circulatory Arrest in the whole surgery greatly, has saved three ramose stitchings of artificial blood vessel and aortic arch, has reduced hemorrhage probability, has reduced the risk of operation.Aortic arch three side support blood vessels change the art formula into mode that complete intracavity is repaired by the mode that the part vascular replacement adds the reparation of part intracavity in the operation of this patent.
But the overlay film frame of the branch vessel in the above-mentioned patent all adopts braiding structure.Because the diameter of branch vessel is less; About about 10-12mm; Bigger with diameter (about the 20～30mm) difference of aortic arch portion, when the overlay film frame of branch vessel adopted braiding structure, the adherent property of support and blood vessel wall was undesirable; Be easy to generate restenosis or overstimulation in the support blood vessel, also maybe be because of the adherent internal hemorrhage due to trauma that do not cause entirely.
Summary of the invention
