As a kind of preferred version of a kind of sacculus dilating catheter described in the utility model, described a plurality of development signs divide on the conduit being located between any one end of sacculus and liquid injection hole.
As a kind of preferred version of a kind of sacculus dilating catheter described in the utility model, the number of described development sign is two.
As a kind of preferred version of a kind of sacculus dilating catheter described in the utility model, the material of described outer sacculus is nylon.
As a kind of preferred version of a kind of sacculus dilating catheter described in the utility model, the material of described internal layer sacculus is macromolecular material.
As a kind of preferred version of a kind of sacculus dilating catheter described in the utility model, the material of described internal layer sacculus is polyimide material.
The beneficial effects of the utility model are, a kind of sacculus dilating catheter of the present utility model, monolayer sacculus dilating catheter is replaced by a kind of two cover sacculus dilating catheter device, simple in structure, easy to use, reduce the risk that causes liquid to reveal because of sacculus explosion in traditional operation, for the operation of row balloon expandable, saved the time, effectively reduced the number of times of again changing sacculus after sacculus explosion, alleviate patient's misery, thereby effectively improved operation quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the broken section structural representation of front view of the preferred embodiment of a kind of sacculus dilating catheter of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1.
In figure: 1 is that outer sacculus, 2 is that internal layer sacculus, 3 is that development sign, 4 is that conduit, 5 is that threeway handle, 6 is that liquid injection hole, 7 is liquid injection port.
The specific embodiment
A kind of sacculus dilating catheter described in the utility model, it comprises: sacculus (not shown), sign 3 develops, conduit 4 and threeway handle 5, described conduit 4 one end connect sacculus and run through sacculus, from sacculus one end, extend to the sacculus other end, described conduit 4 other end connecting tee handles 5, described threeway handle 5 is provided with liquid injection port 7, described liquid injection port 7 connects with described conduit 4, the described conduit 4 that is positioned at sacculus is provided with liquid injection hole 6 and a plurality of development sign 3, described sacculus comprises outer sacculus 1 and internal layer sacculus 2, the coated described internal layer sacculus 2 of described outer sacculus 1.
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with this utility model.
Refer to Fig. 1, the broken section structural representation of the front view that Fig. 1 is a kind of sacculus dilating catheter of the present utility model.As shown in Figure 1, described a kind of sacculus dilating catheter, it comprises: sacculus (not shown), development sign 3, conduit 4 and threeway handle 5.
Described conduit 4 is fixedly connected with sacculus, described conduit 4 is through to the sacculus other end from sacculus one end, and stretches out, and one end away from sacculus of described conduit 4 is connected with threeway handle 5, threeway handle 5 is provided with liquid injection port 7, and described liquid injection port 7 connects with described conduit 4.
The described conduit 4 that is positioned at sacculus is provided with liquid injection hole 6 and a plurality of development sign 3, and now, described liquid injection hole 6 is all coated in sacculus with a plurality of described development signs 3.
