Description
Technical field
This utility model relates to biomedical engineering technology field, more specifically, a kind of is used for the damage of complicated visceral vessel " bridging " artificial blood vessel that performs the operation.
Background technology
Owing to accidentally injuring many trunks when wound causes many abdominal cavity trunk amputation injuries, belly cavity tumor radical correction cleaning lymph node, internal organs reverse and cause irreversibly loses the many abdominal viscera blood vessel injury that the reasons such as the blood supply of internal organs or intestinal tube cause, and it will be very complicated and difficult that clinical vascular is rebuild.The appearance of artificial blood vessel facilitates the development of vascular bypass art: the patent No. be 200820124607.0 Chinese patent disclose a kind of winding type bypass blood vessel, it is the artificial blood vessel belonging to single channel bridging, but single channel bridging can inevitably cause the asymmetric of flow field, suture zone, thus make the impact being subject to bridging pipe blood flow bottom suture zone; The patent No. be 200820110192.1 Chinese patent disclose a kind of bridging artificial blood vessel of symmetry, thus avoid the eddy current that single channel puts up a bridge to the impact bottom tremulous pulse and formation, facilitate artery blood flow unimpeded; But the bridge blood vessel of symmetry can not meet abdominal part many internal organs blood vessels.
Summary of the invention
The purpose of this utility model is to provide a kind of to be damaged for complicated visceral vessel " bridging " artificial blood vessel that performs the operation, this blood vessel can not only be put up a bridge abdominal organs blood vessel simultaneously, and can avoid because of vascular flow dynamical asymmetry and the eddy current that sharply changes and formed, blood washing away and reducing thrombosis risk blood vessel coupling part can be reduced, ensure that blood flow is unimpeded.
The purpose of this utility model is achieved by the following technical programs:
A kind of be used for the damage of complicated visceral vessel " bridging " artificial blood vessel that performs the operation, comprise major blood vessel and some one-level branch vessel, the internal blood vessel of the coupling part of described major blood vessel and one-level branch vessel is provided with the dividing plate being parallel to major blood vessel axis, and the internal blood vessel of coupling part is at least separated into two independently chambers by described dividing plate.
As everyone knows, endovascular local hemodynamic studies characteristic depends on arterial vascular geometry consumingly, the planform of grafts and artery stitch is the key factor affecting grafts long-term effectiveness, studies have reported that and grafts geometry is optimized, hemodynamics can be improved, thus blood flow smooth and easy after being conducive to vascular bypass, the timely supply of blood, substantially improves the prognosis of operation.
Blood flow asymmetric and sharply change can have a strong impact on the flow direction of blood, affect the smoothness of blood, prior art also has the report of some artificial blood vessels improved, but mostly these reports are to improve the shape of blood vessel itself, such as, make symmetrical blood vessel into, and the blood vessel of this symmetry only may be used for some simple vascular bypass surgeries, but the bypass surgery of abdominal organs blood vessel can not be used for, first device of the present invention is made up of major blood vessel and branch vessel, thus meet the bridging of abdominal organs blood vessel, in addition, the creationary coupling part in major blood vessel and branch vessel of device of the present invention arranges the dividing plate being parallel to major blood vessel axis, the blood vessel chamber of coupling part can be divided into the chamber of completely independently at least two by this dividing plate, like this, the blood flowing to major blood vessel branches to different branch vessel naturally in coupling part, thus for the blood supply of different organs blood vessel, meanwhile, the blood of major blood vessel in coupling part because the existence of dividing plate decreases the eddy current of blood, thus ensure blood flow smooth and easy.
Preferably, in said apparatus, the quantity that dividing plate separates rear formed chamber is consistent with the quantity of one-level branch vessel.
In order to meet the demand of the bypass surgery of the internal organs blood vessel of different size further, further, one-level branch vessel of the present invention is also provided with some secondary branch vessel.
Correspondingly, the internal blood vessel of the coupling part of described one-level branch vessel and secondary branch vessel is provided with the dividing plate being parallel to one-level branch vessel axis equally, and the internal blood vessel of coupling part is at least separated into two independently chambers by described dividing plate.
Preferably, the quantity of the inner separate chamber formed of described first order vessel is consistent with the quantity of secondary branch vessel.
The prognosis of the internal diameter impact operation of blood vessel, for avoiding the formation of post-surgical vascular stenosis and forming thrombosis, further, in the above-mentioned artificial blood vessel of the present invention, the internal diameter of described major blood vessel is 10 ~ 12mm, and the internal diameter of one-level branch vessel is 5 ~ 7mm, and the internal diameter of secondary branch vessel is 3 ~ 4mm.
Compared with prior art, this utility model has following beneficial effect:
This utility model provides and a kind of to damage for complicated visceral vessel " bridging " artificial blood vessel that performs the operation, comprise major blood vessel and some one-level branch vessel, the internal blood vessel of the coupling part of described major blood vessel and one-level branch vessel is provided with the dividing plate being parallel to major blood vessel axis, and the internal blood vessel of coupling part is at least separated into two independently chambers by described dividing plate.Like this, major blood vessel and one-level branch vessel can be used for the bridging meeting different organs blood vessel, and the blood flowing to major blood vessel branches to different branch vessel naturally in coupling part, thus for the blood supply of different organs blood vessel; Meanwhile, the blood of major blood vessel in coupling part because the existence of dividing plate decreases the eddy current of blood, thus ensure blood flow smooth and easy.Device described in the utility model can meet the quick bypass surgery of multi viscera blood vessel, greatly shortens operating time.
