Detailed description of the invention
As shown in Figure 1, a kind of stent delivery system, the guide head assembly 2 that including Yarn guide component 1, there is guide effect,
For storage and protective cradle and play propelling movement effect outer tube assembly 3, for protect Yarn guide component 1 and play support reinforcing make
Intermediate tube assembly 4, for fixing and lock the locking device 5 of Yarn guide component 1.
As shown in Figure 4, Yarn guide component 1 includes metal core filaments 11, the far-end being coated on metal core filaments 11 and radiopaque
Soft 12, be coated on the outer overlay film 13 of the near-end of metal core filaments 11.Being formed on soft 12 of Yarn guide component 1 can be with guiding
Offset supporting of setting of head assembly 2 sets portion 14, supports and sets portion 14 and be formed at the near-end of soft 12.
Support the internal diameter of the external diameter setting portion 14 external diameter more than outer overlay film 13 and the far-end more than guide head assembly 2, thus lead
Can be set in slidably on the outer overlay film 13 sections of Yarn guide component 1 to head assembly 2, and when guide head assembly 2 moves to distalmost end
Time, guide head assembly 2 sets portion 14 and offsets with supporting and set thus stop guide head assembly 2 to continue distal movement, when support releases
Bi Hou, Yarn guide component 1 can be withdrawn from from internal stent together with guide head assembly 2.
As shown in accompanying drawing 1 and 3, guide head assembly 2 includes having the 13 sections of cavitys passed of outer overlay film for Yarn guide component 1
Guide head 21, the counterpart 22 being formed on guide head 21, outer tube assembly 3 is formed can be in mating connection with counterpart 22
Auxiliary section 35, when guide head assembly 2 is connected with outer tube assembly 3, counterpart 22 is connected with auxiliary section 35；Work as guide head
When assembly 2 and outer tube assembly 3 are separated, counterpart 22 is separated with auxiliary section 35.In the present embodiment, counterpart 22 be two right
Claiming to be arranged on the convex closure on guide head 21, auxiliary section 35 is provided in groove or the through hole of outer tube 31 far-end of outer tube assembly 3.
Guide head assembly 2 also includes the first developing ring 23 being arranged on the near-end of guide head 21.
As shown in figure 1 and 2, outer tube assembly 3 includes the outer tube 31 with cavity, the second development being arranged on outer tube 31
Ring 32 and the 3rd developing ring 33, being arranged on the outer tube operating portion 34 of the near-end of outer tube 31, support is accommodated in and is positioned at the second developing ring
In the cavity of 32 and the 3rd outer tubes 31 between developing ring 33.The near-end of guide head assembly 2 and the far-end of outer tube assembly 3 are by upper
State counterpart 22 mutually detachably connected with auxiliary section 35.The outer overlay film of Yarn guide component 1 13 sections leading to through outer tube operating portion 34
The cavity of hole and outer tube 31 is so that outer tube assembly 3 can be set on the outer overlay film 13 sections of Yarn guide component 1 slidably.
Intermediate tube assembly 4 includes having the middle pipe 41 of cavity, is arranged on the middle pipe operating portion 42 of the near-end of middle pipe 41, is arranged on
The stent holder 43 of the far-end of intermediate tube assembly 4, middle pipe operating portion 42 is connected with locking device 5, and middle pipe 41 inserts outer tube 31
Being slidably connected with outer tube assembly 3 phase, the outer overlay film of Yarn guide component 1 13 sections passes the through hole of middle pipe operating portion 42, the chamber of middle pipe 41
The endoporus of body and stent holder 43 is so that intermediate tube assembly 4 can be set on Yarn guide component 1 slidably.
Locking device 5 is the female Luer of a standard the most respectively, and the far-end of locking device 5 is grasped with middle pipe
Make being connected proximally by female Luer of portion 42.The outer overlay film of Yarn guide component 1 13 sections through locking device 5 inner chamber so that
Obtain locking device 5 can be set in slidably on Yarn guide component 1 and can fix and lock Yarn guide component 1.The tool of locking device 5
Body structure is not the emphasis of this patent protection, as long as being capable of the fixing of Yarn guide component 1 and the structure of locking function.
When stent delivery system is during conveying, Yarn guide component 1 first arrives guide position, due to guide head assembly
2 are connected with outer tube assembly 3, therefore, guide head assembly 2 with outer tube assembly 3, intermediate tube assembly 4 together with locking device 5 along
Yarn guide component 1 carries, and carries out support off-position by the second developing ring 32 on outer tube 31 and the 3rd developing ring 33
Confirming, after location confirmation to be released, Yarn guide component 1 is locked by locking device 5, is ready for the release of support.
When support is discharged by stent delivery system, outer tube operating portion 34 is pulled to make outer tube assembly 3 towards proximal location
Pulling back, remaining part keeps original position motionless, and guide head assembly 2 is separated with outer tube assembly 3 under the tension force effect of support,
Frame discharges in outer tube assembly 3.
Before support discharges the most completely, as found, off-position is improper, can be locked by locking device 5, pull middle pipe
Operating portion 42 drives intermediate tube assembly 4 to move proximally to, and the stent holder 43 on intermediate tube assembly 4 can hold support together towards closely
End is mobile, and the position progressively re-moved by support between the second developing ring 32 and the 3rd developing ring 33 of outer tube 31.
After support discharges, locking device 5 unlocks, and pulls Yarn guide component 1 to move toward near-end, makes to drive to setting portion 14
Guide head assembly 2 moves toward near-end and internal stent after release moves to guide head assembly 2 and is connected with outer tube assembly 3,
Then Yarn guide component 1 locked by locking device 5, pulls middle pipe operating portion 42 or Yarn guide component 1 to make induction system retreat to external
As it has been described above, we are illustrated fully according to spirit of the invention, but the present invention is not limited to above-described embodiment
And implementation.The practitioner of correlative technology field can carry out different changes in the range of the technological thought of the present invention is permitted
And implement.
