Dual balloon catheter.
Background technique
In sacrococcygeal region malignant tumour or placental presentation operation, generally require to block the blood flow of arteria iliaca communis.Mesh
Preceding clinically common way is that foley's tube is delivered to abdominal aorta by intervention operation and is expanded, and blocks abdomen actively with this
The blood flow of arteries and veins and arteria iliaca communis.However the balloon diameter that this method uses is larger, it is necessary to using the sheath of larger outer diameter, therefore
It is also larger to injury of human.Further, since abdominal aorta is connected with the arteria renalis, blood is being carried out to abdominal aorta using foley's tube
When flow resistance is broken, takes and pay attention at quarter avoiding impacting the arteria renalis, virtually increase operating difficulty and risk.
Based on the above reasons, directly block arteria iliaca communis than blocking abdominal aorta to be easier by clinician with foley's tube
Receive.However, conventional foley's tube is unsuitable for blocking left and right arteria iliaca communis simultaneously since arteria iliaca communis is divided into left and right two
Blood flow, therefore, it is a kind of relatively good solution that the blood flow of left and right arteria iliaca communis is blocked using dual balloon catheter.
In addition, the intervention path of arteria iliaca communis is shorter compared with other blood vessels, block the step of performing the operation relatively easy, because
This, how being further simplified arteria iliaca communis and blocking surgical procedure is also a good problem to study.
