Further, the first kind coil 21 for being formed at first is detachably secured in operation handle 4.Preferably, such asShown in Fig. 2 and Fig. 4, the distal end of the operation handle 4 is provided with fixed block 7, and the first kind coil 21 is removably securedOn fixed block 7.Consequently, it is possible to first kind coil 21 is connected with fixed block 7, it is easy to pull binding wire 2 and tighten up in artSupport 3, and then, first kind coil 21 is removed on self-retaining block 7, just can release being fixedly installed for first kind coil 21.
Then, with continued reference to Fig. 1, it is preferable that the phase of the first kind through hole and Second Type through hole along the peplosOpposite side is symmetrical arranged, and the line of multiple first kind through holes is on same straight line and parallel to the art medium-height trestleAxis direction.
As shown in figure 3, in a preferred embodiment, the near-end connection of the main body rack 31 of art medium-height trestle 3 of the present inventionArtificial blood vessel 33.In some pathological changes, in such as only involving the pathological changes of descending aorta and left subclavian artery, artificial blood vessel 33 is easy toDirectly with the own vascular suture of human body.
As shown in fig. 6, in operation process, above-mentioned artificial blood vessel 33 can also further connect another section of artificial blood vessel34, in other pathological changes, in such as involving the aortic arch even pathological changes of ascending aorta, repair and substitute by artificial blood vessel 34Parts of lesions blood vessel simultaneously has vascular suture by oneself with human body.
Presently preferred embodiments of the present invention as described above, but be not limited to the scope disclosed in above-described embodiment, such asThe mode that is fixedly installed of one type coil 21 is not limited to be connected with fixed block 7, then for example, the second end of the binding wire 2 is notIt is confined to be connected with wire grip 42, but for example, the quantity of the first kind through hole and the quantity of Second Type through hole are not limited toIn one-to-one corresponding.Additionally, the binding wire 2 penetrates the direction of first kind through hole as towards the direction of Second Type through hole,The binding wire 2 passes the direction that the direction of first kind through hole as deviates from Second Type through hole, and in the same manner the binding wire 2 is wornEnter the direction of Second Type through hole as towards the direction of first kind through hole, the binding wire 2 passes Second Type through holeDirection is as away from the direction of first kind through hole.
In sum, the installation method of art medium-height trestle of the invention has following excellent with method for releasing and conveyer devicePoint：
Firstly, since use only disengageable binding wire, only the corresponding peplos of binding wire i.e. releasable need to be extracted out, and thenIt is positioned in blood vessel (such as aortic arch) by band branch or without the art medium-height trestle release of branch；Install in art with prior artThe method of support is compared, and using the installation method of the present invention, be oppositely arranged on peplos logical only need to be sequentially passed through using binding wireHole simultaneously forms the coil of fastening structure, and the first kind coil for being formed at first is removably secured at partial through holes, soThe first end and/or the second end for pulling binding wire afterwards can be tightened up to peplos and be made art medium-height trestle in compressive state, this receiptsTight process is relatively simple, it is not easy to malfunction, and production efficiency is high.
Secondly, using the method for releasing of the present invention, being fixedly installed for the first kind coil that formed at first need to be only released, andThe second end for pulling binding wire is releasable art medium-height trestle, and release process is equally simple, easily operated, not error-prone, and efficiencyIt is high.
Additionally, art medium-height trestle of the invention is installed and method for releasing, when the side branch stent of the art medium-height trestle of the present inventionAfter being accurately positioned, the binding wire discharges main body rack from the near-end of art medium-height trestle to distal end order, during releaseThe proximal part of main body rack is hardly shifted, even and if the distal portions of main body rack have significantly nature cripetura also notThe side branch stent displacement near main body rack near-end can be caused, thus, avoiding in operation collateral displacement and at a specified future date collateral beatingThe problems such as folding or Side branch occlusion, significantly improve the therapeutic effect of aortic disease.
In addition, in actual process of binding, often through after one coil of several through holes or formation, just can be by pullingAt least one end in the two ends of binding wire is tightening up peplos, it is to avoid be relatively difficult to tighten up peplos after the multiple coils of snapping, because oneBe present outside expansionary force in the art medium-height trestle in aspect peplos, deposit between another aspect binding wire and between binding wire and peplosIn frictional force, so, the first end and/or the second end for pulling on binding wire is arranged on after the completion of threading and/or in threading process,Binding wire is timely and effectively tightened up with more convenient.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, thisAny change, modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claimsScope.
