Description
Technical field
The present invention relates to a kind of medical science surgical operating instrument articles for use, outstanding reference and a kind of aorta anastomosis device and using method thereof.Belong to cardiovascular surgical procedure technique with the apparatus field.
Background technology
In the prior art, the aneurysmal effective Therapeutic Method of thoracoabdominal aortic aneurysm and extremity trunk is a surgical operation.But the problem that exists is that operation risk is big, to the specification requirement height of surgeon at present.Analyzing from the operation angle, how to carry out vascular anastomosis safely and fast, is to improve success rate of operation, reduces the key factor of operative mortality and minimizing postoperative complication.Particularly carry out the operative treatment of serious symptom trunk disease (as complicated and dissecting aneurysm widely), can finish vascular anastomosis quickly and safely be the successful prerequisite of operation.
The method of present vascular anastomosis mainly is to carry out sutured anastomosis with suture.This is a kind of safe and effective procedure, but to the specification requirement height of surgeon, and to spend more operating time, also need repair Lou blood place sometimes.If an operation will be done a plurality of anastomotic stoma, then to obviously increase operation risk with sewing up for a long time or mending-leakage.Therefore, many doctors to complicated and widely aneurysm abandon operative treatment, and take expectant treatment.But the mortality rate of expectant treatment is high, as complicated and dissecting aneurysm widely.The report that does not need the endoluminal vascular prosthesis sewed up is recently also arranged, non-stitching endoluminal vascular prosthesis is fixed with two sutures, the strong umbilical cord of reuse is banded in aneurysm on the ring of endoluminal vascular prosthesis, but occurs blood forms false aneurysm in vascular ring penetrates into aorta wall danger.Therefore, be a long felt need for a kind of simple, quick, safe vascular anastomosis method.
Summary of the invention
The objective of the invention is to overcome the identical long shortcoming of spended time that exists of existing suture, a kind of aorta anastomosis device that can carry out vascular anastomosis quickly and safely is provided.
For achieving the above object, the present invention has taked following technical proposals:
A kind of aorta anastomosis device is characterized in that: comprise hard cylinder rack, hard cylinder rack is made up of the raised structures of two edge and the groove structure of middle indent, and the point of ten～16 projections of two～four rows is arranged on the groove; The interior outside of cylinder stent has artificial blood vessel to hold, and artificial blood vessel extends to a side; The strip fixing band, fixing band one side has ring for fixing, and the fixing point of three row's projections is arranged on the fixing band.
The present invention has following beneficial effect:
The present invention is used between the artificial blood vessel, coincideing between human vas and the artificial blood vessel.The hard cylinder rack that holds artificial blood vessel is inserted in the human vas, and the reuse fixing band is pricked the mode of tightening up with ring and is coincide.This vascular anastomosis device is simple to operate, and it is reliable to coincide.

Fig. 2 is a hard rack axonometric chart of removing artificial blood vessel.
Fig. 3 is an axial arrangement cutaway view of removing the hard rack of artificial blood vessel.
Fig. 4 is the axonometric chart of fixing band.
Fig. 5 is practical effect figure (hard rack that will have artificial blood vessel to hold is inserted in the human vas, and the reuse fixing band is fixed and tightened up).
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done to describe further.
Concrete enforcement:
With reference to Fig. 1, Fig. 2, Fig. 3, present embodiment comprises hard cylinder rack 1, and hard cylinder rack is made up of the raised structures 2 of two edge and the groove structure 3 of middle indent, and ten～16 protruding points 4 of two～four rows are arranged on the groove structure; The interior outside of cylinder stent has artificial blood vessel 5 to hold, and artificial blood vessel 5 extends to a side.
With reference to Fig. 4, present embodiment comprises strip fixing band 6, and fixing band one side has ring for fixing 7, and the fixing point 8 of three row's projections is arranged on the fixing band.
In the present embodiment: hard cylinder rack 1 is made by Nitinol, rustless steel, hard cylinder rack is made up of the raised structures 2 of two edge and the groove structure 3 of middle indent, ten～16 protruding points 4 of two～four rows are arranged on the groove structure 3, and protruding point 4 is hemisphere or small cylinder 4; The length of described support 1 is that 1.0～2.0cm, diameter are 0.8～3.0cm, and the thick of groove structure place is 0.5～2mm; The raised structures of described two edge is wide to be 1.0～2.0mm, high 1.0～2.0mm, and the top is a circular arc; Protruding point 4 in the described groove structure, the end is radius 0.5～1.0mm circle, height is hemisphere or the cylinder (the circle firmly top of body is the grand shape of circle) of 1.0～2.0mm.Strip fixing band 6 is made by Nitinol, rustless steel, described fixing band 6 long 20～80mm, wide 8～16mm, thick 0.5～2mm; Described ring for fixing 7 is a rectangle, long 2～3mm, wide 8～16mm, high 1～2mm; The fixing point 8 of described projection, the end is the circle of radius 0.5～1.0mm, height is hemisphere or the cylinder (cylindrical top is the grand shape of circle) of 1.0～2.0mm.Artificial blood vessel (5) is made by politef or terylene.
Present embodiment constitutes a kind of artificial blood vessel stapling apparatus.During practical application, the hard rack 1 that holds artificial blood vessel is inserted in the human vas 9, fixing band 6 free-ends of no ring for fixing 7 one sides are filled in the ring for fixing 7, move down fixing band 6 again to hard rack groove structure 3 corresponding human vas 9, in groove structure 3, tighten up fixing band 8 gradually, human vas 9 and the support 1 that holds artificial blood vessel are close to, are connected and the hemostatic purpose to reach; In the process of tightening up fixing band 6, the protruding point 4 on the groove structure 3 is staggered with the fixing point 8 of fixing band upper process and compresses human vas 9, and can prevent tissue necrosis; At last fixing band 6 free-end opisthotonos are fixed on the ring for fixing 7, in case it unclamps.(Fig. 5 is practical effect figure, and 10 for surrounding the fixing band outside the human vas)
The concrete operations explanation:
Demonstration:
The ends of vessels that at first free good plan is coincide, the hard cylinder rack that will hold artificial blood vessel is again inserted in the human vas of intending coincideing, and fixes the position; The fixing band of no ring for fixing one side is inserted in the ring for fixing, move down fixing band, hold hard cylinder rack, and fixing band is placed in the groove of hard cylinder rack with fixing band, adopt to tighten up gradually fixedly to bring and carry out vascular anastomosis, and prevent anastomotic leakage blood.In tightening up the process of fixing band, the fixing point of protruding point on the groove structure and fixing band upper process is staggered and compresses human vas.After recovering the blood flow at vascular anastomosis place,, also can continue to tighten up fixing band if any leaking blood.
