Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to a kind of sacculus dilating catheter.
Background technology
Cardiovascular disease is the high disease of a class sickness rate, have a strong impact on the quality of the life of people, wherein congenital stenosis of pulmonary artery is the disease that right ventricular outflow blocks, it is comparatively common congenital heart disease, valve portion, infundibulum, pulmonary trunk and branch stenosis can be divided into according to narrow positions, wherein the most common is that pulmonary arterial wall is narrow, Therapeutic Method common in clinical treatment has percutaneous balloon pulmonary valvoplasty, and pulmonary arterial wall is narrow, aortic stenosis uses balloon dilatation treatment.But the tissue when doing balloon dilatation on stenosis arterial wall easily comes off and enters blood circulation, easily results in blockage at small artery place.
Utility model content
The purpose of this utility model is to provide a kind of sacculus dilating catheter, has the feature by sucking-off stenosis arterial wall is organized.
In order to achieve the above object, the technical scheme that this utility model provides is: a kind of sacculus dilating catheter body, comprise catheter body, described catheter body is provided with the first shutoff sacculus, dilating sacculus and the second shutoff sacculus, described conduit offers the first filling channel, second filling channel and the 3rd filling channel and imbibition passage, the first gas outlet is offered in described first shutoff sacculus, the second gas outlet is offered in described dilating sacculus, the 3rd gas outlet is offered in described second shutoff sacculus, the first liquid outlet is offered between described first shutoff sacculus and dilating sacculus, the second liquid outlet is offered between described dilating sacculus and the second shutoff sacculus, described first gas outlet is connected with the first inflation inlet by the first filling channel, described second gas outlet is connected with the second inflation inlet by the second filling channel, described 3rd gas outlet is connected with the 3rd inflation inlet by the 3rd filling channel, described first liquid outlet is connected with liquid sucting port respectively by imbibition passage with the second liquid outlet.
The beneficial effects of the utility model are: this utility model is by comprising catheter body, described catheter body is provided with the first shutoff sacculus, dilating sacculus and the second shutoff sacculus, described catheter body offers the first filling channel, second filling channel and the 3rd filling channel and imbibition passage, the first gas outlet is offered in described first shutoff sacculus, the second gas outlet is offered in described dilating sacculus, the 3rd gas outlet is offered in described second shutoff sacculus, the first liquid outlet is offered between described first shutoff sacculus and dilating sacculus, the second liquid outlet is offered between described dilating sacculus and the second shutoff sacculus, described first gas outlet is connected with the first inflation inlet by the first filling channel, described second gas outlet is connected with the second inflation inlet by the second filling channel, described 3rd gas outlet is connected with the 3rd inflation inlet by the 3rd filling channel, described first liquid outlet is connected with liquid sucting port respectively by imbibition passage with the second liquid outlet.Thus reach the effect can organized from conduit sucking-off stenosis arterial wall.
