Blood-supply pipeline of thoracic and abdominal aortic branch vessels

Abstract

The application discloses a blood-supply pipeline of thoracic and abdominal aortic branch vessels, and belongs to the technical field of medical devices. According to the present invention, the blood-supply pipeline comprises a plurality of aortic branch connection pipes, and each aortic branch connection pipe merges at the end on the same side to form a confluence pipe; each aortic branch connection pipe is covered with an elastic capsular membrane around the other end surface so as to form an elastic capsule after the elastic capsular membrane is filled with a medium; and each elastic capsular membrane is in communication with a capsular membrane pipe. According to the present invention, the blood-supply pipeline is in communication with aortic branch vessels through the aortic branch connection pipes, such as the insertion into the aortic branches (intercostal artery, abdominal celiac artery, superior mesenteric artery, left and right renal artery, inferior mesenteric artery, etc.),the blood-supply pipeline is fixed by filling the elastic capsular membrane with the medium, the connection of the confluence pipe and an extracorporeal circulation pipeline are used to supply bloodto the aortic branch vessels in a thoracoabdominal aorta replacement surgery, the damage to organs or spinal cord caused by intraoperative ischemia is avoided, and the occurrence of complications is reduced, such as postoperative paraplegia, renal function failure, intestinal necrosis, liver function failure, etc.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a thoracoabdominal aortic branch blood supply channel. Background technique [0002] When performing thoracoabdominal aorta replacement surgery in cardiovascular surgery, it is necessary to resect the thoracoabdominal aorta and replace it with artificial blood vessels. Arterial branch vessels were connected with artificial blood vessels to reconstruct the branches of the thoracoabdominal aorta. Due to incision of the thoracoabdominal aorta and anastomosis of each branch, it is technically difficult and takes a long time, and each branch vessel has different degrees of ischemic time, resulting in postoperative paraplegia, liver failure, renal failure, and intestinal ischemic necrosis and other serious complications. At the same time, after incision of the aorta, blood overflows from the exposed branches of the thoracoabdominal aorta, making the operative field full of bloo...

Problems solved by technology

Due to incision of the thoracoabdominal aorta and anastomosis of each branch, it is technically difficult and takes a long time, and each branch vessel has different degrees of ischemic time, resulting in postoperative paraplegia, liver failure, renal failure, and intestinal ischemic necrosis occurrence of serious complications

At the same time, after incision of the aorta, the exposed thoracoabdominal aortic branch vessels will overflow with blood, making the operative field full of blood, affecting the clarity of the operative field and seriously hindering the progress of the operation.
