Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
A kind of butt junction location device is present embodiments provided, which can be applied to use in intervention operation
In executing windowing on tissue 2 to be operated, perhaps quilting jobs tissue 2 to be operated for diaphragm, vascular wall or can be placed in master
Overlay film frame etc. in arteries 100.In the present embodiment, to be opened on the overlay film frame in aorta vessel 100
It is introduced for window operation.As shown in Figure 1, the butt junction location device specifically includes guide end 1, butt end 4 and adjuster 7.
Wherein, it is provided with the first magnetic pole 3 on guide end 1, the second magnetic pole 5 is provided on butt end 4.One end and butt end 4 of adjuster 7
One end connection of the second magnetic pole 5 of upper setting can change position of second magnetic pole 5 relative to the first magnetic pole 3 by adjusting adjuster 7
It sets, to make the second magnetic pole 5 close to the first magnetic pole 3, reaches the adsorption range of the first magnetic pole 3.The first magnetic is reached to the second magnetic pole 5
After the adsorption range of pole 3, under the suction-operated of the first magnetic pole 3, the second magnetic pole 5 can be automatically aligned to the first magnetic pole 3, thus
Realize that butt end 4 and guide end 1 are docked.
First magnetic pole 3 and the second magnetic pole 5 can use permanent magnet, electromagnet or other magnetisable materials.When the first magnetic pole 3
When with the second magnetic pole 5 using permanent magnet, the polarity of the opposite end of the first magnetic pole 3 and the second magnetic pole 5 needs on the contrary, permanent magnet can be with
Selection uses one kind or two of samarium-cobalt magnet, ndfeb magnet, ferrite lattice, alnico magnet or siderochrome cobalt magnet
Kind, that is to say, that the first magnetic pole 3 and the second magnetic pole 5 can be to select permanent magnet made of different materials.
Middle medical staff needs under the guide of image documentation equipment compared to the prior art, carries out windowing work by experience
Industry.In the present embodiment, conduit 4 and guide end 1 are connect certainly by the realization that is automatically aligned to using the second magnetic pole 5 and the first magnetic pole 3
Dynamic docking can guarantee that accurately, steadily windowing can be executed on tissue 2 to be operated after window-opening mechanism passes through butt end 4
Effect not only contributes to reduce windowing difficulty, improves windowing precision and windowing rate, additionally it is possible to reduce fenestration operation to surgical device
The requirement of tool, medical staff's experience and image documentation equipment.Further, since utilizing the first magnetic pole 3 and second in docking operation
