The autologous endocranium itself cut off in endocranium chamber involves the top surface of pedestal, unclamps jig arm, and jig arm is returned under the elastic force of torsion spring
The card pin arrived again in initial position, i.e. jig arm is snapped onto in the neck on pedestal through autologous endocranium, so that by autologous hard brain
Film is fixed on pedestal, autologous dural repairing is completed, after Flexible latch system is absorbed by the body, positioned at base bottom surface
Together with artificial dura mater will coincide automatically with the autologous endocranium positioned at base top surface.
The fixing line for suspending automatic identical endocranium system in midair is additionally provided with the middle part of the connection shaft.Due to whole lock
Button system is the flexiblesystem that resorbable material is made, and can arbitrarily bend and possess sufficiently ductile not easy to break, therefore repairing
, it is necessary to set fixing line when mending than larger endocranium, whole automatically identical endocranium system is suspended on skull, prevents hard
Meninx is peeled off and exterior dura hydrops.
The flap valve for wearing drainage tube is additionally provided with the artificial dura mater, the quantity of the flap valve is two, position
In in pedestal and being distributed in the both sides of connection shaft.When needing drainage, drainage tube can be drawn from flap valve, without drainage
When, flap valve is in closed state.
The torsion spring is made of medical titanium bar.
Compared with prior art, its advantage is the utility model：
By two semi-circular jig arm, by positioned at the artificial dura mater of base bottom surface and positioned at the autologous hard brain of base top surface
Film is snapped together, as pedestal and hemispherical locktabs are absorbed by the body, and realizes artificial dura mater and autologous dural automatic
It coincide, greatly shortens operation time, reduce operation risk, reduce postoperative complication, while artificial dura mater position
Protective layer is formed between brain tissue and fastener system, injured brain tissue and neural blood vessel in operating process is prevented.
