Plugging device as shown in Fig. 7 a and Fig. 8 a, it stretches the wing 136 between upper disc 11 and lower disc 12, when needs regulate upper disc 11, during chucking power between lower disc 12, by braiding structure ligation cover 134, stretch the wing 136 and be drawn out to outside through lower disc ligation cover 121 together, formed by the braiding of shape memory wire mesh shape owing to stretching the wing 136, after the stretching, extension wing 136 is drawn out to the outside of lower disc ligation cover 121, stretch the shape that the wing 136 release expands into original setting, stopped braiding structure ligation cover 134 again get back to lower disc ligation cover 121 in probability, now the shape of plugging device becomes as shown in Fig. 7 b, Fig. 8 b, and the distance between upper disc 11, lower disc 12 changes comparatively before to some extent, thus have adjusted the chucking power between disc 11, lower disc 12.
As shown in Fig. 9 a to Figure 10, push rod 2 comprises push rod shell 21, push rod inner core 22, push rod inner core 22 intracavity in push rod shell 21 moves along axis or rotates, the end of push rod shell 21 and lower disc ligation are overlapped 121 and are removably connected, and the end of push rod inner core 22 and the movable end of Flexible Connector 13 removably connect.Wherein, the end of push rod shell 21 is overlapped 121 with lower disc ligation and is threaded.As shown in Fig. 9 a to Fig. 9 f, the end of push rod inner core 22 is connected by clip 23 with the movable end of Flexible Connector 13; As shown in Figure 10, the end of push rod inner core 22 is threaded with the movable end of Flexible Connector 13.
Use the method for releasing of above-mentioned adjustable plugging device, mainly comprise the following steps:
1) push rod 2 be connected with stopper 1, pull push rod 2, drawn in delivery sheath 3 by stopper 1, it specifically comprises the following steps,
1. the end of the movable end of Flexible Connector 13 with push rod inner core 22 is connected, the movable end of the Flexible Connector 13 as shown in Fig. 9 a to Fig. 9 c is connected by clip 23 with the end of push rod inner core 22, and the movable end of Flexible Connector 13 as shown in Figure 10 and the end of push rod inner core 22 are threaded connection;
2. push rod inner core 22 is drawn in push rod shell 21 together with the movable end of Flexible Connector 13, as shown in figure 9d;
3. push rod shell 21 and lower disc ligation are overlapped 121 to be fixedly connected with, as shown in figure 9d;
4. push rod inner core 22 is together with the movable end of Flexible Connector 13, moves or rotate in the cavity of push rod shell 21 along axis, the length of adjustable elastic connector 13 between upper disc 11 and lower disc 12, as shown in figure 9e;
5. pull push rod 2, stopper 1 is drawn in delivery sheath 3;
2) by delivery sheath 3, stopper 1 is delivered to lesion locations;
3) push push rod shell 21, upper disc 11 is discharged;
4) push push rod shell 21 and push rod inner core 22, release Flexible Connector 13 simultaneously;
5) push rod inner core 22 keeps motionless, pushes push rod shell 21, and lower disc 12 part discharges;
6) push rod shell 21 and lower disc ligation are overlapped 121 to be separated;
7) whether firmly stablely stopper 1 is observed, if necessary, the length of adjustable elastic connector 13 between upper disc 11 and lower disc 12; Wherein, the process of the length of adjustable elastic connector 13 between upper disc 11 and lower disc 12 comprises the following steps,
1. push away before push rod shell 21, make push rod inner core 22 and Flexible Connector 13 be recovered to the interior intracavity of push rod shell 21;
2. push rod shell 21 and lower disc ligation are overlapped 121 to be fixedly connected with;
3. the movable end of push rod inner core 22 and Flexible Connector 13 is moved along axis together or rotates, the length of adjustable elastic connector 13 between upper disc 11 and lower disc 12 in the cavity of push rod shell 21;
4. push rod shell 21 and lower disc ligation are overlapped 121 to be separated.
8) draw back push rod shell 21, push rod inner core 22 and Flexible Connector 13 expose and discharge completely;
9) movable end of push rod inner core 22 with Flexible Connector 13 is separated, now, if when Flexible Connector 13 is spring 131 as shown in figure 9f, then the part automatic curled that 121 outsides are overlapped in lower disc ligation stayed by spring 131, can not retract in lower disc ligation cover 121 again, if Flexible Connector 13 is pipe type netted braiding structure 133 as shown in Figure 10, then stretches the wing 136 and stopped the probability that pipe type netted braiding structure 133 is retracted.
In said method, if stopper 1 as shown in Figure 2, then in release or while regaining Flexible Connector 13, also discharge together or regain waist 14.
In sum, the adjustable plugging device of the present invention and method for releasing, by the length of adjustable elastic connector between upper disc and lower disc, reach the object regulating upper chucking power between disc and lower disc, make plugging device more firmly stable, fit better with lesion locations, the pathological changes of different size, different length can be adapted to, can correct when the recyclable release property again of this adjustable plugging device makes operation meet accident simultaneously, reduce operation risk and operation technique difficulty.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
