Abstract

The invention provides an aorta blocking device for total aortic arch replacement and stented elephant trunk surgery. The aorta blocking device comprises a supporting artificial blood vessel and a blocking device body, the blocking device body comprises a catcher, a balloon arranged at one end of the catcher and a pressurizing and depressurizing device capable of enabling the balloon to expand andcontract, and the balloon after expanding by pressurizing can be fixed in the supporting artificial blood vessel and can block the same at a supporting position. The blocking device comprising the balloon is creatively applied in total aortic arch replacement and stented elephant trunk surgery and combined with the supporting artificial blood vessel arranged in a descending aorta to block blood flow of the aorta, so that deep hypothermia is avoided, deep hypothermia circulation arrest time of the descending aorta is shortened remarkably, postoperative complication is reduced greatly, and operative effect is improved.

Description

technical field [0001] The application belongs to the technical field of blocking devices, and in particular relates to an aortic blocking device for total aortic arch replacement and elephant trunk stenting. Background technique [0002] Total aortic arch replacement plus elephant trunk stent surgery is widely used in the treatment of thoracic aortic aneurysm and acute and chronic type A aortic dissection. recognized. The deep hypothermia and circulatory arrest technique must be used for this operation, that is, the whole body needs to be cooled during the operation. When the temperature of the nasopharynx drops to 18-20°C, unilateral selective cerebral perfusion can be performed through the axillary artery or innominate artery. Circulation arrest in the lower body means that there is no blood perfusion in the organs perfused by the descending aorta, including the spinal cord, liver, kidneys, and digestive tract. The proximal end and the distal end of the arch are anastom...
