Abstract

The invention discloses an intra-cavity circulation tube for maintaining artery blood supply of abdominal cavity internal organs. The intra-cavity circulation tube comprises a main catheter and multiple branched tubes, the two ends of the main catheter are open, main catheter balloons are arranged at the positions, close to the two ends, of the main catheter respectively and separately connected with a main balloon filling tube, multiple main tube connectors are formed in the side wall of the main catheter, and the branched tubes are connected with the main catheter through the main tube connectors; the two ends of the branched tubes are open, a branched tube balloon is arranged at the end, deviating from the main catheter, of each branched tube, and a branched tube balloon filling tube isinstalled on each branched tube balloon. The intra-cavity circulation tube can solve the problems that in the prior art, an intra-cavity circulation tube is complex in operation and inconvenient to use, is easy and convenient to operate, wide in application range and high in reliability.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an internal bypass tube for maintaining the blood supply of abdominal visceral arteries. Background technique [0002] Thoracoabdominal aortic aneurysms and some retroperitoneal tumors usually involve visceral arteries such as the renal artery, superior mesenteric artery, and celiac artery. When performing these operations, it is necessary to block these visceral arteries with blocking forceps for aneurysm resection or tumor resection, and visceral artery occlusion for more than 30 minutes may lead to ischemia and necrosis of the corresponding organs. Surgical techniques are extremely demanding, and there is a high possibility of organ ischemia and necrosis after surgery. Therefore, it is of great significance to design a bypass device that can block the blood flow of the aorta and satisfy the blood supply of the visceral artery to improve the diagnosis and treatment of thoracoabd...
