Aortic arch replacement is required in aortic arch aneurysm or Stanford type a aortic dissection surgical treatment. In aortic arch replacement, it is necessary to stop systemic blood circulation at low temperature. Brain tissue needs to be protected in the process of stopping circulation, and the current common measures for low-temperature stopping circulation brain protection clinically comprise unilateral selective brain perfusion, bilateral selective brain perfusion and the like. Unilateral selective cerebral perfusion is mainly performed through axillary artery or innominate arterial intubation, and is widely adopted at present in China, but if Willis loop development in the brain is abnormal, severe cerebral complications caused by contralateral cerebral perfusion insufficiency can be caused; bilateral selective cerebral perfusion is performed by inserting a right axillary artery and inserting a left common carotid artery or inserting a bilateral common carotid artery, has definite cerebral protection effect, and is less in domestic application at present. The bilateral selective cerebral perfusion method needs to use a cerebral perfusion cannula, and the prior art generally uses a catheter, one end of which is inserted into the left common carotid artery, and the other end of which is connected with an extracorporeal circulation machine to carry out arterial perfusion. As no special cerebral perfusion cannula exists in China, the medical instrument and the method have the advantages of simple operation and reliable perfusion, reduce the cerebral ischemia time as much as possible, reduce the occurrence of cerebral complications and improve the success rate of aortic arch surgery, and become the problems to be solved urgently in the field.
Disclosure of Invention
An object of the utility model is to the aforesaid not enough, provide a brain perfusion intubate that has the artery anti-reflux function that is arranged in stopping circulation cardiovascular operation in-process brain protection to use to solve present domestic dedicated selectivity brain perfusion intubate problem of not having yet, improve the success rate that brain protection effect stops circulation aortic arch operation.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the cerebral perfusion cannula with the artery backflow prevention function for cardiovascular surgery comprises a cerebral perfusion cannula body and is characterized by further comprising a blood backflow prevention balloon, wherein the blood backflow prevention balloon is installed at the arterial end of the cerebral perfusion cannula body, and the balloon contraction side tube communicated with the blood backflow prevention balloon and a balloon side tube locking switch for controlling the balloon contraction side tube to be opened and closed.
Preferably, the artery end of the cerebral perfusion cannula body is in a round taper shape or a hemispherical shape.
Preferably, at least one blood transfusion side hole is arranged between the arterial end of the brain perfusion cannula body and the blood backflow prevention balloon.
The utility model has the advantages that:
the utility model provides a be used for cardiovascular surgery to stop circulating operation in-process brain protection applied cerebral perfusion intubate that has artery anti-reflux function, through be slick and sly toper at brain perfusion intubate body one end (artery end), can be convenient put into common carotid with brain perfusion intubate in, after putting into the completion, open the sacculus side pipe locking switch of sacculus side pipe one end, inject into normal saline into the sacculus and make it expand and block the artery, prevent brain blood backward flow, guarantee brain perfusion flow, close sacculus side pipe locking switch. The other end of the connecting body and the extracorporeal circulation machine can carry out selective cerebral perfusion through the common carotid artery. The brain protection can be exactly carried out by bilateral selective brain perfusion through a right axillary artery intubation tube and a left common carotid artery selective brain perfusion intubation tube or bilateral common carotid artery selective brain perfusion intubation tube. In addition, in the process of perfusion, the side holes at one end of the brain perfusion cannula body can avoid blood perfusion obstacle caused by the adherence of the cannula and the artery wall.
The utility model provides a brain that is arranged in cardiovascular surgery to stop circulating operation in-process brain protection to use fills intubate with artery anti-return function simple and convenient and practical, convenient operation, the brain fills definitely, and the protection is effectual, and simple structure is suitable for production simultaneously, easily promotes.
