Embodiment
The present invention is described in detail below in conjunction with accompanying drawing, it is clear that described embodiment is only the present invention one
Divide embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making
The every other embodiment obtained under the premise of creative work, belongs to protection scope of the present invention.
As shown in figure 1, the invention provides a kind of sacculus dilating catheter, several knots are provided with the hollow conduit 1
Structure is identical and the balloon structure of independent air inlet, can realize the expansion to individual position, improves efficiency and applicability, and the first of end
Balloon structure includes first outer tube 2 of the coaxial sleeve located at the outside of hollow conduit 1, be provided with the first outer tube 2 with outside first
The sacculus body 3 that sleeve pipe 2 is connected, it is provided with the first outer tube 2 and is inflated for the blow gun 4 to the air inlet of sacculus body 3, sacculus body 3
Afterwards, internal to be provided with some hollow out passages 5 for being easy to blood flow, the outer wall of sacculus body 3 is provided with some strip air bags 7, when expander enters
After entering blood vessel, strip air bag 7 contacts diseased region at first so that diseased region is increased by pressure, easily pushes up broken or squeezes disease
Become position, improve the state of an illness of patient.Some anti-skid bulges 6 are provided with the strip air bag 7, prevent sacculus body from shifting, in addition,
Anti-skid bulge 6 can also produce space between vascular wall, increase CBF, prevent bloodstream blocking, also, the hollow conduit 1
Developing mark patch 10 is provided with positioned at the inner segment of sacculus body 3.
As shown in Fig. 2 it is arranged with the second outer tube 8, the second outer tube 8 and the phase of strip air bag 7 outside first outer tube 2
Connect and be provided with air inlet, venting channels 9 are provided between strip air bag 7, the strip air bag 7 is axle with hollow conduit 1
The heart, axially it is uniformly distributed in the outside of sacculus body 3；The hollow out passage 5 is axle center with hollow conduit 1, in being axially uniformly distributed in
The outside of EC 1, the hollow out passage 5 pass through sacculus body 3.
It is exemplary, it is provided with that 2 structures are identical and the balloon structure of independent air inlet on the hollow conduit 1, the second ball
