Among the figure, 1, sacculus; 2, spherical recalled nitinol alloy stent; 3, opening; 4, memorial alloy tinsel; 5, extensible grasp; 6, full skirt; 7, axis; 8, lever.
The specific embodiment:
As shown in Figure 1, the sacculus 1 of inserting in the recalled nitinol alloy stent 2, preceding in not filling (gas or liquid), sacculus 1 is a strip.
As shown in Figure 2, behind the about 0.5-0.8mL of filling gas or liquid, sacculus 1 diameter is between 9mm-13mm.Generally speaking, its wall thickness is 0.2mm, internal diameter 9.6mm, external diameter 10.0mm.In addition, additional 2mm is thick for sacculus 1 one ends, the diaphragm of diameter 2.0mm.
Fig. 3 is the state of recalled nitinol alloy stent 2 when temperature is lower than 10 ℃, and it is similarly a cylindrical shape.
As shown in Figure 4.Under the effect of body temp, recalled nitinol alloy stent 2 expands voluntarily becomes sphere, and its diameter of sphere net basket that recalled nitinol alloy stent 2 constitutes is 12mm, and the two ends of ball are the hole of diameter 3mm, and the support force of recalled nitinol alloy stent 2 is 50-60g/mm
2(30-42 ℃).During use, earlier spherical recalled nitinol alloy stent 2 is discharged in the bronchus of the target lobe of the lung (section).All footpaths the best part embeds the mucosa of bronchial wall and fixes, the opening 3 of diameter 3mm by mount proximal end is put into recalled nitinol alloy stent 2 with sacculus shown in Figure 11 again, suitably full sacculus 1 is with recalled nitinol alloy stent 2 inner chamber shutoff, be the target lobe of the lung (section), adjust sacculus 1 pressure to working standard, device is placed and is finished.
Form state at last as Fig. 5.
Embodiment 1 operation principle is as follows: above-mentioned recalled nitinol alloy stent 2 and sacculus 1 are inserted target leaf (or section) bronchus successively, the full sacculus 1 in combination back, outward appearance should be a spherical structure, utilize the Memorability of support, embed bronchial lumen, full sacculus 1 is fixed in the beaded support, thus the stifled effect of performance bolt.The lobe of the lung that gets clogged (section) withers because of wherein gas absorbed in 2-3 days gradually naturally, thereby reduce the intrathoracic volume that this lobe of the lung (section) occupies because of excessive emphysema, be beneficial to the recovery of other lobes of the lung (section) function, reach the purpose of improving patient's pulmonary function.
Above-mentioned plugging device is placed in the bronchoscopic service aisle with convergence state, utilize special release to insert target leaf (or section) bronchus, plugging device after the release launches to become aforesaid duty automatically under the body temperature condition, thus performance bronchus plugging action.This plugging device is because of the performance of material itself, can have unidirectional flap valve function, can allow by portion gas or mucus in the leaf of shutoff (section), under certain intrinsic pressure effect by sacculus with discharge with the gap that airway walls attaches mutually, reduce the complication after placing.Withered because of wherein gas absorbed in 3-5 days gradually by the lobe of the lung of shutoff (section), thereby reduce the intrathoracic volume that this lobe of the lung (section) occupies because of excessive emphysema, be beneficial to the recovery of other lobes of the lung (section) function, reach the purpose of improving patient's pulmonary function.
The structure of embodiment 2 as shown in Figure 6, the full skirt 6 of self-expanding formula bronchial occlusive device is attached to having on the spiral-shaped memorial alloy tinsel 4, the central part of full skirt 6 is axis 7, axis 7 near-ends have lever 8, it and axis 7 are integrative-structures.The far-end of axis 7 is fixedly connected with 1 group of extensible grasp 5, memorial alloy tinsel 4 also has 1 group of extensible grasp 5 with the link place of axis 7, extensible grasp 5 is that 3 memorial alloy tinsels 4 launch to be the anchor shape, be parabolic shape when wherein every memorial alloy tinsel 4 launches, extensible grasp 5 has 2 groups among the embodiment 1, the extensible grasp 5 identical outside stretching, extension of angle each other in every group; Parabola direction after 2 groups of extensible grasps 5 stretch is opposite.
Fig. 7 is embodiment 3 full skirt deployed condition structural representations.Embodiment 3 difference from Example 1 are that its full skirt 6 is on the spiral-shaped memorial alloy tinsel 4 of rightabout attached to two as shown in the figure.
Fig. 9 is embodiment 4 deployed condition structural representations.As shown in the figure, its difference from Example 2 is that its full skirt 6 is attached on three equidirectional spiral-shaped memorial alloy tinsels 4 of uniform distances.
It is the umbrella-shaped structure of 12 ± 5mm that full skirt 6 overlay films launch the back diameter; Far-end---the tinsel of the other end for exposing that the umbrella top is relative with parabola shaped outside stretching, extension, forms the anchor shape.Umbrella skeleton can be histocompatibility medical material metal or alloy preferably, and as using Ultimum Ti, then the support force of support (F) is 50-60g/mm
2(30-42 ℃).
Fig. 8 is embodiment 3 collapsed state structural representations.
Figure 10 is embodiment 4 collapsed state structural representations.
During practical operation, plugging device is placed in the service aisle of branchofiberoscope elder generation end with convergence state earlier, state when packing up such as Fig. 8 and shown in Figure 10, it arrives target leaf (or section) bronchus with tracheascope elder generation end, utilizes special applicator that plugging device is sent into target leaf (or section) bronchus.Inserting the bronchial plugging device of target leaf (or section) launches under the condition of body temperature automatically, become the anchor shape of far-end and the umbrella shape of near-end, the anchor arm that stretches around tube chamber plays the effect of being fixed in the bronchial lumen, and open umbrella-shaped structure is attached at the bronchus medial wall uniformly, plays plugging action.Be aforesaid duty, thus performance bronchus plugging action.This plugging device is because of the performance of material itself, has unidirectional flap valve function, can allow by portion gas or mucus in the leaf of shutoff (section), because of under the effect of intrinsic pressure variation of moment (as cough) by full skirt 6 with discharge with the gap that airway walls attaches mutually, to reduce the complication after placing.
It is placed in the bronchus of selecting by with self-expanding formula bronchus plugging device, utilizes the interior gas of lung to absorb naturally, progressively causes the pulmonary atelectasis of this section or inferior section in 3-5 days, eliminates the serious lung tissue of emphysema to full influence of Pulmonary Function thereby reach.
