Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
This utility model is a kind of fixing plugging device separated with obturation, by implanting fixing device 1 respectively and implanting
Locking device 2 realizes the conveying of trickle sheath pipe；Simultaneously as fixing device 1 and the separation of locking device 2, can be for not
Select different fixing device 1 with lesion locations, and according to the plugging effect in art increase obturator number, truly
Realize controlledization and the optimization of closure.
This utility model device includes fixing device 1, is provided with locking device 2 in fixing device 1, and fixing device 1 is " king "
Character form structure, fixing device 1 is provided with hole, and hole is less than fixing device 1, and the size in fixing device 1 centre position is less than it
The size at two ends.Fixing device 1 can be the network structure of niti silk braiding, it is also possible to be that niti manages or stainless steel tube cuts into
Structure, its common feature is stably to be supported on defect location, and will not be moved the risk that comes off；In the present embodiment, fixing dress
The two ends putting 1 are all the metal racks cut, as it is shown in figure 1, realized the control of pore size by the density of cutting.
General, fixing device 1 has two effects, is stably to fix respectively；And constraint wadding, prevent it from escaping.Fixing device 1
Hole less, utilize the surface tension of fine pore to realize the effusion of apparatus inside stuffing.
Locking device 2 can be that metal batches thing, such as metal elastic spring coil；Can also be macromolecule floccule, such as, wash
Synthetic fibre floccule；Or thick organic solvent liquid, such as hydrogel；Or the solvent that blood solidifies can be made, such as dehydrated alcohol
Deng.
For locking device 2 be metal batch thing in the case of, because of metal, to batch thing physical size relatively big, and can guarantee that stable
Integrally, so the designed porosity of fixing device 1 is between 30-60%；It is the feelings of macromolecule floccule for locking device 2
Condition, the designed porosity of fixing device 1 is at 50-80%；For locking device 2 be viscous liquid or make that blood solidifies molten
The situation of agent, easily disperses because of liquid to be separated into several less liquid block, and the designed porosity of fixing device 1 is more than 70%.Here
Porosity refer to the ratio of hole and whole uniform planar on a uniform planar.
During treatment, as shown in Figure 7, Figure 8, fixing device 1 is transported to lesion locations, after release by induction system a part
It is stably fixed at defect lesion locations, as shown in Figure 5.Then filled to fixing device internal injection by induction system b part
Locking device, due to locking device 2 implant number can be with free body outer control, when closure apparatus plugging effect at once does not reaches
Can continue to fill up to during Expected Results, oppress fixing device and perienchyma thus realize the effect entirely shut further,
As shown in Figure 6.
Wherein, a part is the sheath canal path of fixing device 1, and b part is the sheath canal path of locking device 2.
As shown in Figure 8, the sheath canal path b part of locking device 2 can stretch out sheath tube head end, enters fixing device 1 internal,
Thus discharge locking device 2.
Embodiment 2
In the present embodiment, the two ends of fixing device 1 are all the metal racks worked out, as in figure 2 it is shown, it is by regulation
Braiding silk radical is how many or braiding string diameter slightly washes the control realizing pore size.
Other are same as in Example 1.
Embodiment 3
In the present embodiment, fixing device 1 is cutting and the compound rest of braiding, i.e. the two ends of fixing device 1 are respectively cut
Cut branch frame and braided support, as shown in Figure 3.
Other are same as in Example 1.
Embodiment 4
In the present embodiment, fixing device 1 is the design of funnel-form spring, as shown in Figure 4, by regulation unit height inner spring
The number of turns or the spring string diameter that rotate slightly wash the control realizing pore size.
Other are same as in Example 1.
