Specific embodiment
It is described in the utility model proximally and distally consistent with the definition of other catheter proximal ends and distal end in the prior art.
That is, proximal end described in the utility model is one end that operator operates commuting lever；Distal end described in the utility model is close to disease
One end of change, is referred to as head end.
As shown in Figures 2 and 3, the utility model provides a kind of reverse seal wire capture conduit.It includes 1 He of catheter main body
Proximal end guiding tube 2, seizure pipe 3 and distal end guiding tube 4 in catheter main body 1, proximal end guiding tube 2 and distal end guiding tube 4 divide
Not Wei Yu 3 two sides of seizure pipe, three Guan Xiangtong.Proximal end guiding tube 2 is trumpet type, and nozzle 21 diameter in proximal end is greater than far-end mouths 22
Diameter.The far-end mouths 22 of proximal end guiding tube 2 are connect with 3 one end of seizure pipe, and seizure pipe 3 is equal diameter pipe, the diameter of seizure pipe 3
Identical as the diameter of far-end mouths 22, the two is fixedly connected, and in order to more smooth in use process, recommendation uses integrally connected side
Formula.
The proximal end nozzle 41 of the other end connection distal end guiding tube 4 of seizure pipe 3；41 diameter of proximal end nozzle and seizure pipe 3 are straight
Diameter is identical, and the two is fixedly connected, and in order to more smooth in use process, recommendation uses integrally connected mode.Distal end guiding tube 4 is loudspeaker
Type, 41 diameter of proximal end nozzle are less than 42 diameter of far-end mouths；1 side wall of catheter main body is equipped with crack 11, crack 11
It is communicated with proximal end guiding tube 2, seizure pipe 3 and distal end guiding tube 4, can conveniently withdraw from capture conduit after completing exchange guidewire.
In the present embodiment, the axis of seizure pipe 3 is parallel to 1 axis of catheter main body, and close to 11 side of crack, it is therefore an objective to
It is more convenient for withdrawing from capture conduit.In actual use, it may be designed in the structure coaxial with catheter main body 1.
In the present embodiment, reverse seal wire captures the overall length 30mm of conduit, and wherein guidance length of tube in proximal end is 10mm, seizure pipe
Length is 10mm, and it is 10mm that distal end, which guides length of tube,.The proximal end nozzle diameter of proximal end guiding tube be in 1.5~1.8mm,
Recommend to use 1.65mm in the present embodiment.3 diameter of seizure pipe is recommended to use in the present embodiment in 0.5~0.8mm
0.77mm.42 diameter of far-end mouths of distal end guiding tube 4 is recommended to use 1.65mm in 1.5~1.8mm.
In order to be more convenient for operating to reverse seal wire capture conduit, the proximal face of catheter main body 1 is equipped with commuting lever
5。
Inversely seal wire capture conduit is made of medically acceptable material for this, recommends using softness and has supportive
Plastic material.
This reverse seal wire captures the use process of conduit are as follows: as shown in figure 4, reverse seal wire A enters forward direction in the direction of the arrow
Guiding catheter C.Firstly, pushing this reverse seal wire along positive seal wire E captures conduit to positive guiding catheter distal end, reverse seal wire A
Enter this reverse seal wire in the direction of the arrow to capture in the distal end guiding tube 4 of conduit, while pushing positive microtubular along positive seal wire E
D enters in seizure pipe 3 via the proximal end guiding tube 2 that this reverse seal wire captures conduit and converges with reverse seal wire A.
As shown in figure 5, reverse seal wire A adjustment is penetrated in positive microtubular D using lesser lacuna in seizure pipe 3.
Then, positive microtubular D passes through total occlusion portion B to blood vessel distal end along reverse seal wire A.
As shown in fig. 6, withdrawing from reverse seal wire A, positive seal wire F is sent in the direction of the arrow to occlusion disease along positive microtubular D
The distal end change portion B, withdraws from positive microtubular D.
As shown in fig. 7, this is inversely led using crack 11 after this reverse seal wire capture conduit withdraws from positive guiding catheter C
Silk capture conduit is separated with forward direction seal wire F, and subsequent balloon expandable and stenting procedure are carried out along positive seal wire A.This is reverse
Seal wire capture conduit withdraw from operation can use clamping commuting lever 5 operated.
