The first sheath 1 is a sheath of 12F or more. Where F is the unit of the sheath, "French," which is a description of the sheath circumference. For example, a 6F sheath may have an inner diameter of about 2mm, and a 24F sheath may have an inner diameter of about 8 mm. The first sheath 1 can be implanted through the left common carotid artery 10 at the proximal aortic arch 11. Specifically, in the case of using the device for intracranial diversion between the aorta and the left carotid artery, the first sheath 1 is implanted proximally through the left common carotid artery 10 to the aortic arch 11. For example, in this embodiment, a large sheath of 12F is implanted proximally through the left common carotid artery 10 to the aortic arch 11.
The second sheath 2 is longer than 6 cm and is a short sheath. The second sheath 2 can be implanted at the distal end of the left internal carotid artery 12. Wherein the length of the second sheath 2 is greater than the depth of implantation of the second sheath 2 into the left internal carotid artery 12. Specifically, when the device for intracranial diversion between the aorta and the left carotid artery is used, the second sheath 2 is implanted distally of the left internal carotid artery 12. For example, in the present embodiment, a short sheath of 6F is implanted into the distal end of the left internal carotid artery 12, the implantation depth is 4-6 cm, and the length of the second sheath 2 is greater than the implantation depth, i.e. the tail end of the second sheath 2 is exposed. At the rear end of the second sheath 2 there is at least one branch 20 to facilitate connection with other sheaths.
The length range of the third sheath pipe 3 is 45-80 cm, and the third sheath pipe is a long sheath. The third sheath 3 is a 6F-8F sheath. The third sheath 3 can be implanted at one end of the proximal aortic arch 11 close to the aortic root, and the tail end of the third sheath 3 is in the left subclavian artery 13. Wherein the length of the third sheath 3 is larger than the implantation depth of the third sheath 3. Specifically, when the device for intracranial drainage between the aorta and the left carotid artery is used, the third sheath 3 is implanted proximally through the left brachial artery to the aortic arch 11 near the aortic root. For example, in the present embodiment, an 8F long sheath (60 cm in length) is implanted proximally through the left brachial artery to the aortic arch 11 near the aortic root, and the length of the third sheath 3 is greater than the implantation depth of the third sheath 3, i.e. the tail of the third sheath 3 is exposed. At the end of the third sheath 3 there is at least one branch 30 to facilitate connection with other sheaths.
The second sheath tube 2 and the third sheath tube 3 are communicated. Specifically, the device for intracranial diversion of the aorta and the bilateral carotid artery further comprises a diversion tube 4, and two ends of the diversion tube 4 are respectively connected with the branch tube 20 at the tail end of the second sheath tube 2 and the branch tube 30 at the tail end of the third sheath tube 3, so that the second sheath tube 2 is communicated with the third sheath tube 3. The flow diverter 4 is a double-ended flow diverter of conventional construction in the art, available to those skilled in the art. In the present embodiment.
The utility model discloses the device of the intracranial diversion of aorta and left side carotid passes through the interim blood supply passageway that external diversion pipe established, can simply carry out the interim blood supply of left side carotid and intracranial blood vessel when going the tectorial membrane support to the aorta arch and cover, treats that the tectorial membrane support windows branch and rebuilds the back, resumes original blood flow. The method for extracorporeal circulation has the advantages of simple operation, small wound, no need of blocking carotid artery, no need of interrupting intracranial blood flow, little plaque falling, no influence on operation and low stroke incidence of patients.
The operation of the device for intracranial diversion of the aorta and the left carotid artery of the present invention is described below. When using the device of the utility model for intracranial diversion of aorta and left carotid artery, the flow direction of blood is shown by the arrow of dotted line and the arrow of solid line in the figure, wherein, the arrow of dotted line shows the blood flow direction before the windowing of left internal carotid artery blood vessel and in the windowing operation, and the arrow of solid line is the blood flow direction after the windowing of left internal carotid artery blood vessel.
After the general anesthesia is successful, the left carotid artery and the left subclavian artery are incised and exposed under the aseptic condition, and the intracranial diversion method of the aorta and the left internal carotid artery is established. The method mainly comprises the following three parts:
the first part establishes a diverting sheath for the left common carotid artery and the left internal carotid artery. A first sheath 1 is implanted through the left common carotid artery 10 towards the proximal end of the aortic arch, and a second sheath 2 is implanted at the distal end of the left internal carotid artery 12.
The second part establishes a left subclavian artery shunt sheath. A third sheath 3 is implanted through the left brachial artery towards the proximal end of the heart to the aortic arch near the aortic root.
The third part establishes a diversion system for the left subclavian artery and the left internal carotid artery. The branch pipes at the tail end of the second sheath pipe 2 and the branch pipes at the tail end of the third sheath pipe 3 are respectively connected through the shunt pipes 4, so that the second sheath pipe 2 is communicated with the third sheath pipe 3 to ensure blood supply of the left intracranial artery.
Before the left internal carotid artery is windowed, a covered stent (not shown in the drawing) is implanted into the aortic arch 11, and at the moment, the covered stent can block the blood circulation at the left common carotid artery 10, so that after the covered stent is implanted and in the left internal carotid artery windowing operation process, the blood flows into the left internal carotid artery 12 through the third sheath tube 3, the shunt tube 4 and the second sheath tube 2 to ensure the blood supply of the left intracranial artery; after the left internal carotid artery vessel is windowed, the left common artery 11 is no longer blocked by the stent graft, and then blood flows into the left internal carotid artery 12 through the first sheath 1 and the second sheath 2 to ensure the blood supply of the left intracranial artery.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
