Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Embodiment 1
A kind of plugging device as shown in Figure 1 and the attachment structure of induction system：Including plugging device 1 and induction system, closure
The connection end of device 1 is provided with tubing 2, and induction system includes the sleeve 3 being connected with each other and push pipe 4, and sleeve 3 is away from push pipe 4
One end be threadedly coupled with tubing 2.
Operation closure septal defect is intervened mainly including conveying plugging device, strutting plugging device, separation plugging device using internal medicine
With its induction system and recovery induction system four-stage.Plugging device induction system mainly includes sleeve 3 and push pipe 4.Sealing
Plugging device 1 is sent to specified location by stifled device delivery phase, the induction system of plugging device, and screw connection structure can ensure conveying
During plugging device 1 linked together all the time with induction system；And then the stage is strutted into plugging device, plugging device 1 is in specific bit
Put to strut completely and block septal defect；Subsequently into plugging device 1 and the separation phase of induction system, in separation process, instead
To rotate push pipe 4, due to sleeve 3 with push pipe 4 be fixedly connected, rotate backward push pipe 4 when, the synchronous backward of sleeve 3 rotation,
So as to which sleeve 3 be separated with tubing 2；Finally enter the recovery stage of push pipe 4 and sleeve 3.
The connection of plugging device 1 and induction system can be improved to a certain extent using the technical scheme in the present embodiment 1
Fastness, effectively prevent in the prior art using the tail button and induction system for snapping connection plugging device tail end dop loosen or
The generation of direct break-off, so as to improve the security of operation.
As shown in Figure 2 a, external thread section 201 is fixedly connected by way of laser welding or bonding with tubing 2.It is this
The mode of split processing screw thread is fairly simple.
