Detailed description of the invention
Below provide specific embodiment of the utility model, it should be noted that this utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Embodiment:
Defer to technique scheme, as shown in Figure 1 to 11, the present embodiment provides a kind of holder device that can pass through smoothly for bifurcation coronary artery, comprises first propping up seal wire 4 along limit and inserting the limit support 8 that tremulous pulse 2 is propped up on limit; Comprise master's support 7 of finally inserting a main tremulous pulse 1 along a main seal wire 3;
Also be included in after inserting limit support 8, shrivel the extruding sacculus 9 of limit support 8 along a main seal wire 3, extruding sacculus 9 is extracted out from a main seal wire 3 after shriveling limit support 8;
Then prop up seal wire 4 to insert a shutoff sacculus 10 and serve as a contrast along limit the end be flattened at limit support 8, when in the end inserting main support 7 by a main seal wire 3, intercept a main support 7 and contact with the direct of limit support 8, realize mainly propping up passing through smoothly of support 7.
Concrete, shutoff sacculus 10 comprises ball sealer ductus bursae 10-1, ball sealer ductus bursae 10-1 outer wall is provided with elastic shutoff sacculus utricule 10-2.
Concrete, extruding sacculus 9 comprises extrusion ball ductus bursae 9-1, extrusion ball ductus bursae 9-1 outer wall is provided with elastic extruding sacculus utricule 9-2, extrusion ball ductus bursae 9-1 is provided with the light tight indicia band 9-3 of extruding sacculus.A main support sacculus 5 and Bian Zhi support sacculus 6 have the structure identical with extruding sacculus 9, and a main support sacculus 5 and Bian Zhi support sacculus 6 are for discharging main support 7 and Bian Zhi support 8.
Further, ball sealer ductus bursae 10-1 is provided with the light tight indicia band 10-3 of shutoff sacculus, locates for labelling under X-ray.
Further, shutoff sacculus utricule 10-2 is radially thinning gradually centered by ball sealer ductus bursae 10-1, is convenient to shutoff sacculus utricule 10-2 and presents flattening expansion.
Further, in flat after shutoff sacculus utricule 10-2 expands, passing through smoothly of a main support 7 is convenient to.
Further, the diameter after shutoff sacculus utricule 10-2 expands is greater than the diameter of limit branch vessel 2, realizes complete shutoff.
Work process of the present utility model is as described below:
During enforcement, a two PTCA seal wires i.e. main seal wire 3 and Bian Zhi seal wire 4 is sent into the far-end of main branch vessel 1 and limit branch vessel 2 respectively, while after support 8 inserts, extruding sacculus 9 is sent into along a main seal wire 3, the part of limit support 8 being charged into main branch vessel 1 shrivels, extract extruding sacculus 9 out, shutoff sacculus 10 is positioned by X-ray according to the light tight indicia band 10-3 of shutoff sacculus on ball sealer ductus bursae 10-1, shutoff sacculus 10 is propped up seal wire 4 along limit and push to limit branch vessel 2 open proximal, utilize compression pump 11 that shutoff sacculus 10 is fully expanded, various sacculus is all inflated by compression pump 11, continue to push shutoff sacculus 10, until it is obstructed.Subsequently a main support 7 is pushed along a main seal wire 3 lesion becoming owner of branch vessel 1, due to the existence of shutoff sacculus 10 in propelling movement process, winner's support (7) directly can not be contacted with limit support (8), realize passing through smoothly of main support (7).Pumpback compression pump 11 makes shutoff sacculus 10 bounce back, and after withdrawing from shutoff sacculus 10, with suitable earth pressure release master support 7, terminates operation to after kiss expansion.This kind of art formula is applicable to the process of bifurcation coronary artery, especially needs the bifurcated lesions with the process of Crush art formula, can ensure that a main support is smoothly by lesion, reduces operating time, improves therapeutic effect.
