Person) setting, for fixing position of the membrane-repturing device in patient vessel, the inside which passes through positioning element 4 is removable
It is dynamic.
In the present embodiment, positioning element 4 may include the locating support 41 that can be expanded and shrink, in locating support
41 when being in contraction state, and without positioning, user can determine target position with running fix bracket to target position
It afterwards, can be fixed in the blood vessels by locating support 41 by the expansion of locating support 41.
Positioning element may also include sheath to control the expansion of locating support and contraction.Fig. 6 is the outer of the membrane-repturing device in Fig. 4
The sectional view of sheath joint.As shown in Figure 5 and Figure 6, the expansion and contraction of locating support can be controlled by the double-deck sheath.
The double-deck sheath includes outer sheath 42 and interior sheath 43, and 42 housing of outer sheath is outside interior sheath 43, interior sheath and outer sheath edge each other
It can axially relatively move, interior 43 housing of sheath fills 12 housing of pipe outside operating stick 11, locating support 41 outside full pipe 12
One end connect with outer sheath 42, the other end of locating support 41 is connect with interior sheath 43, passes through sheath and outer sheath in controlling
Between relative movement to control the expansion and contraction of locating support 41.
For example, locating support 41 can be braided support.It is knitted by least one braided wires by poor superimposing braid, it is adjacent
Braided wires can enclose and be set as network unit.Wherein, the obtuse angle of network unit may range from 91-179 degree or
100-160 degree or 110-150 degree or 115-140 degree or 120-135 degree, preferably 120-135 degree.The braiding of locating support
Pitch (that is, linear distance along axial two crosspoints) is 0.6mm-1.5mm, and preferably 1.0mm is (in the receipts of positioning element 4
Under contracting state).The string diameter of braided wires can be 0.005 inch -0.02 inch.The cross-sectional shape of braided wires can for it is round,
Oval, trapezoidal, diamond shape or rectangle etc..Braided wires can be made of any one of materials described below: Nitinol, 304 stainless
Steel, 316L stainless steel, L605 cochrome and MP35N alloy etc., preferably nitinol alloy wire, so that positioning branch made of braiding
Frame 41 has better radial positioning power and flexibility.
In the present embodiment, braided wires without dextrorotation derotation coiling (that is, braided wires first dextrorotation coiling from front to back, then
Derotation coiling from back to front) locating support is formed, the both ends (free end) of braided wires are located at the both ends of locating support, Ke Yizhi
It connects and is mutually fixed with interior sheath and outer sheath.In other embodiments, which can also pass through at least one braided wires
Turned to by dextrorotation and derotation, at this point, both ends (that is, longitudinal end) imperforation of locating support, respectively with interior sheath and epitheca
Pipe is mutually fixed.
