In a preferred embodiment, the outer shroud edge of described disc support net ring is wavy edge.
In a preferred embodiment, the inner annular edge of described disc support net ring is wavy edge.
In a preferred embodiment, the thickness of described disc support net ring is 2 ~ 2.5mm.
In a preferred embodiment, described disc support net ring is that nickel is admired the closed annular dictyosome of predeterminable profile of B alloy wire braiding.
In a preferred embodiment, the cylindricality waist inner chamber of described support dictyosome offers support scrobicular ring.
In a preferred embodiment, described support scrobicular ring is offered as one or more along the radial direction of described cylindricality waist.
In a preferred embodiment, also comprise: lumbar support net dish; Described lumbar support net ring is corresponding to the diameter of described support scrobicular ring, is fixed in described support scrobicular ring.
In a preferred embodiment, the outer shroud edge of described lumbar support net dish is wavy edge.
In a preferred embodiment, described lumbar support net dish is that nickel is admired the closed dish type dictyosome of predeterminable profile of B alloy wire braiding.
As shown in the above, the beneficial effects of the utility model are, this utility model this utility model by arranging disc supporting network ring in dish-shaped supporting network disc, thus makes the support strength of dish-shaped supporting network disc obviously increase.When lesion portion produces deformity change, when forming deformity surface, can effectively be fixed lopsided pathological tissues, add the partial mold of dish-shaped supporting network disc, and gross distortion can not occur stopper entirety, thus ensure that plugging effect and stopper fixation, difficult drop-off.
