Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Referring to fig. 1-3, there is shown an interventional valve release restraining device comprising an inflatable balloon 100, a first inflation system and a restraining balloon 200 symmetrically disposed at both ends of the inflatable balloon 100 for restraining the expanded position of a valve 300.
The inflatable balloon 100 is used for expanding the valve 300, a first inflation port 110 is formed on the inflatable balloon 100, a first inflation system is used for inflating and deflating the inflatable balloon 100, and the first inflation system is communicated with the first inflation port 110 of the inflatable balloon 100 through a first pipeline 400.
The inflatable balloon 100 can be inflated and deflated repeatedly during the procedure, with only surface contact with the valve 300 and no connection fixation, and can be detached from the valve by means of a catheter when the valve 300 is expanded in place.
The limit airbag 200 is provided with a second inflation inlet 210, the second inflation inlet 210 of the limit airbag 200 is communicated with a second inflation system for inflating and deflating the limit airbag through a second pipeline 500, the first inflation system and the second inflation system are two independent inflation systems, and respectively inflate the inflatable airbag 100 and the limit airbag 200, and are controlled independently and do not interfere with each other.
The maximum outer diameter of the expansion balloon 100 is the same as the maximum inner diameter of the valve 300, different valve sizes can have corresponding expansion balloons to ensure that the expansion balloons are in the best and proper state, and all the materials can completely meet the disinfection requirements of medical instruments.
The specific operation of the invention is as follows:
when the operator conveys the valve 300 to a required position, the limiting air bag 200 is inflated through the second inflation system at the moment, the valve 300 is guaranteed not to be displaced, then the inflation air bag 100 is inflated through the second inflation system, the valve 300 is enabled to be fully expanded, the operator can repeatedly inflate and deflate under the guidance of the operation center exceeding or X-ray, the valve 300 is guaranteed to be expanded at a proper position, finally, the air in the inflation air bag 100 and the limiting air bag 200 is pumped away through the first inflation system and the second inflation system, and the air bags are taken away through the catheter.
In conclusion, the two ends of the expansion air bag are respectively provided with the limiting air bags, so that the valve displacement caused by the expansion of the expansion air bag in the releasing process of the intervention valve is effectively avoided, the accuracy of the releasing position of the intervention valve is ensured, the success rate of valve releasing and the operation quality are greatly improved, and great convenience is brought to the valve replacement work of an operator.
