The mode of above-mentioned connection can be formed in the link position of conehead 300 to even permutation advantageously according to silk 430 is adjusted.Wherein, on
Stating " being connected " specifically can be understood as two adjustings silks 430 and does not adjust not instead of individually, and linkage is adjusted, i.e., when an adjusting
When silk 430 is pulled rearward tight, another adjusting silk 430 forward, forms reverse movement simultaneously.
In the present embodiment, the second control handle 420 can preferably include dentation drawing item and rack brake device.Specifically
For, rack brake device is mutually fixed with adjuster, and dentation pulls item and passes through rack brake device, and dentation pulls one end and the cable of item
440 are connected, and the other end of dentation drawing item is connect with the second control handle 420.
As depicted in figs. 1 and 2, in the present embodiment, adjusting pedestal 450 can also be preferably included by adjusting component 400.
Specifically, the concatermer 110 and set in the rear end of main body 100, positioned at 100 rear end of main body can be set in the adjusting pedestal 450
The rear end (or adjusting ring 220 positioned at 200 rear end of casing) of pipe 200 is connect with adjusting pedestal 450 respectively, that is, is located at main body 100
The concatermer 110 of rear end and the rear end (or adjusting ring 220 positioned at 200 rear end of casing) of casing 200 are relatively fixed.Furthermore the
One control handle 410 and the second control handle 420 are located at the rear end for adjusting pedestal 450, and more adjusting silks 430 and cable 440 divide
It is not arranged in and adjusts pedestal 450.
Further, include the design for adjusting pedestal 450 based on component 400 is adjusted, in the present embodiment, adjust pedestal
450 offer the extraction channel worn for more adjusting silks 430 and cable 440.Wherein, more adjust the extraction that silk 430 is worn
Channel is eccentric channel, and the extraction channel that cable 440 is worn is center channel, alternatively, adjust pedestal 450 offer it is multiple mutually
Independent extraction channel, these extraction channels are worn for more adjusting silks 430 with cable 440 respectively, and in each extraction channel
The quantity of the adjusting silk 430 and cable 440 that wear is not limited to one.In other embodiments, pedestal 450 is adjusted also may not be used
Extraction channel is opened up, and the design of hollow structure can be used, such as the inside of adjusting pedestal 450 can offer cavity, it should
Cavity, which can be used in accommodating, is arranged in the more adjusting silks 430 and cable 440 that adjust pedestal 450.
Further, based on the design for offering extraction channel in pedestal 450 is adjusted, in the present embodiment, arbitrarily
Reducing-flow structure can be preferably provided in extraction channel.Hereby it is possible to avoid the substance of merging environment (such as in blood vessel
Blood) it is flowed out along extraction channel.
It should be noted here that being shown in attached drawing and the conveying device that describes in the present specification is only can use this public affairs
Several examples in many kinds of conveying devices of Kaiyuan reason.It should be clearly understood that the principle of the disclosure is only limitted to absolutely not attached drawing
In show or any part of any details of conveying device described in this specification or conveying device.
For example, it for stent-graft to be placed in being conveyed by the conveying device proposed using the disclosure, is based on
The corresponding design of certain common existing stent-grafts, the dimensional parameters of each structure of conveying device can be used to divide into
Meter.For example, in the present embodiment, the preferable diameter parameters of conehead 300 and main body 100 that conveying device is applicable in are 6mm.When
So, the conveying device illustrated in present embodiment is equally applicable for the conehead 300 and main body 100 of other specifications parameters.Alternatively, In
It, also can be to the phase of conveying device to be more adaptive to the conehead 300 and main body 100 of other specifications parameters in other embodiments
Specifications parameter is closed to be adjusted flexibly.
The exemplary illustration of each chief component based on the above-mentioned conveying device proposed to the disclosure, by bracket people
Work blood vessel is placed in for blood vessel, is illustrated below to the specific conveying merging process of the conveying device proposed using the disclosure.
When conehead 300 moves ahead in Endovascular, the case where such as vessel branch and needing selects one to determine vascular access
Under, operator can adjust control silk by the first control handle 410 of drawing, change the side of conehead 300 (tapered elastomer 310) with this
To and curvature, thus make conveying device selection enter expected vascular access.Scaffold artificial's blood at conehead 300 and its rear
After pipe enters blood vessel approach, casing 200 can be adjusted ring 220 to, removal extension mobile away from the direction of conehead 300 by operator
Covering of the bar 230 to stent-graft, enables stent-graft to be released.
Conveying device Endovascular move ahead need to be by vascular bending complexity in the case where, such as vascularization is sharply bent
Or continuous bend, operator can adjust cable 440 by loosening the second control handle 420, make (the multiple concatermers of main body 100 with this
110) curvature in compliance with blood vessel curvature, so that conveying device be enable to pass through blood under resistance as small as possible
The crooked position of pipe reaches expected implantation site.
For conveying device after stent-graft to be sent to expected implanting and completes positioning, operator can pull second
Control handle 420 adjusts cable 440, is kept fixed the curvature of main body 100 (multiple concatermers 110) with this, is completed at the same time pair
The release of stent-graft.Then loosen the second control handle 420 and adjust cable 440, so that (the multiple concatermers of main body 100
110) curvature in compliance with blood vessel curvature, so that it is curved so that conveying device is passed through under resistance as small as possible
Complete exiting for conveying device in pars convoluta position.
