Hole, the threaded portion 131 are connected on the through hole.Using such structure, when seal wire 1 is not twisted, protective case 2 connects
It is connected on seal wire 1, forms an entirety, it is common to retreat, when needing to wear out the tough tissue of matter, seal wire 1 is twisted, seal wire 1 advances, with
Protective case 2 separates, and then wears out the tough tissue of matter and achieve the goal.
As the preferred scheme of the present invention, be provided through hole or thinned hole 22 on the protective case 2, it is described through hole or
The head end 13 of 22 face seal wire of hole 1 is thinned, it is further preferably using thinned hole 22, hole 22 to be thinned and easily propagates through, and can be by screw thread
Portion 131 is completely disposed within the protection domain of protective case 2, reduces adverse effect caused by threaded portion 131 is set.
As the preferred scheme of the present invention, the threaded portion 131 is made up of laser engraving technique.The depth and spiral shell of screw thread
Line spacing, it can be carried out individually designed according to the difference of specifically used position.
As the preferred scheme of the present invention, a diameter of 1.2mm~0.8mm in the body portion 12.The toughness of guarantee seal wire 1,
Torsional rotation force intensity.
As the preferred scheme of the present invention, the body portion 12 is provided with hydrophilic coating.Hydrophilic coating can attract hydrone to exist
Its surface formed " gel " surface, reduce then pass through resistance.
In use, first ensuring that the contact of head end 13 of seal wire 1 needs the tissue broken through, and ensure directionality, rear molding
End connects the device of selectable punction (such as directly or by converter：Electricity turns), so as to link, seal wire 1 rotates, and drills through tissue.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
