Description
Technical Field
The utility model relates to an aortic cannula safety auxiliary device.
Background
Extracorporeal circulation surgery requires cannulation over the beating heart aorta, through which oxygenated blood is delivered to maintain an efficient blood supply to the body. At present, the main artery intubation used clinically has different modes, the principle is a tubular structure, blood is conveyed through a lumen, the main artery intubation operation is that a surgical knife is used for cutting an incision on the main artery wall by a patient, then the main artery intubation is put in from the incision, if the incision is too large, large bleeding can be caused, the incision can not be put in, the situation that the incision is needed to be changed again and then is made is caused, the incision is too deep, the damage of the main artery rear wall can be caused, the main artery intubation is very important technical training in the culture process of cardiac surgeons, the main artery intubation complication is not unusual clinically, and the life of a patient can be endangered when serious.
Disclosure of Invention
The utility model aims to provide an aortic cannula safety auxiliary device which can smoothly insert an aortic cannula into an aortic cavity.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides an aortic cannula safety auxiliary device, including the main part, match gasbag and fixed gasbag, this main part includes the cavity body of rod, be equipped with the blunt leading-in head at the front end of this cavity body of rod, there is the blade structure in the both sides of this blunt leading-in head, it has the match gasbag to overlap admittedly on the cavity body of rod that is close to the blunt leading-in head, the lateral wall of the cavity body of rod that corresponds the match gasbag is equipped with the side opening, the one end of the vent line A of match gasbag passes through the side opening, the other end is drawn forth from the tail end of the hollow body of rod and is connected pneumatic valve A, the rear end cover at this cavity body of rod has fixed gasbag, this fixed gasbag passes through vent line B and connects pneumatic valve B.
Preferably, the hollow rod body is made of elastic plastic.
The beneficial effects of the utility model are as follows: the aortic cannula safety auxiliary device can easily and smoothly insert the aortic cannula into the aortic cavity, can avoid damage to the back wall and the side wall of the aorta, eliminates serious complications caused by failure of the aortic cannula, reduces operation difficulty and greatly improves operation safety.
Drawings
