Description
Technical field
The present invention relates to medical domain surgical, and in particular to a kind of Special Automatic identical cerebral dura mater system of cranium brain.
Background technology
With the development of neurosurgery equipment and technology, large amount of complex, large-scale craniocerebral operations are carried out.Due to disease
Change involves in extensive range, and surgical wound surface is big, postoperative to need to suture cerebral dura mater, recovers normal physiological structure, reduces cerebrospinal leak, prevents
Only intracranial infection.Although having substantial amounts of cerebral dura mater at present for postoperative duramater reparation, if it is desired to tight closing cerebral dura mater chamber
Need to expend longer operating time and go suture, consume operative doctor energy, extend operating time, at the same also bring it is many and
Disease is sent out, such as, suture needle injured brain tissue, cerebrovascular in sewing process need to reopen cerebral dura mater and stopped blooding；Sewing process
In due to overtension, cause cerebral dura mater gap occur, it is impossible to closed, subcutaneous tissue is drained to outside cerebrospinal fluid, cause postoperative wound
Poor healing, or even there is cerebrospinal fluid leakage, otch cannot heal.Although appearance at present is so-called to exempt to suture cerebral dura mater, also only
It is that artificial dura mater is attached at into brain surface, cerebral dura mater chamber cannot be closed at all.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of automatically identical cerebral dura mater system, lead to
Cross snap close mode, realize artificial dura mater and it is autologous it is dural coincide automatically, so as to reduce operating time, reduce operation risk
And reduction postoperative complication.
For achieving the above object, the technical scheme is that：
A kind of automatically identical cerebral dura mater system, for repairing the autologous cerebral dura mater of cerebral dura mater intracavity, including Flexible latch system

The jig arm of shape, the artificial dura mater is fixed on the bottom surface of pedestal, and the pedestal middle part is communicated with axle, the two ends of the jig arm
Rotated by torsion spring and connection shaft and be connected, the base top surface is provided with multiple draw-in grooves, the jig arm bottom surface be provided with it is multiple with it is described
The card pin that draw-in groove matches, when the torsion spring is in free position, the card pin is fastened in draw-in groove.
When deployed, according to defect cerebral dura mater size, artificial dura mater is pruned, according to bone window experiment material Flexible latch system
The shape of system, automatic cerebral dura mater system of coincideing is inserted in the cerebral dura mater chamber of defect, and the jig arm of pedestal both sides is pulled open upwards, will be hard
The autologous cerebral dura mater itself cut off in meningeal spaces involves the top surface of pedestal, unclamps jig arm, and jig arm is replied under the elastic force of torsion spring
Card pin in initial position, i.e. jig arm is snapped onto in the draw-in groove on pedestal through autologous cerebral dura mater, so as to by autologous cerebral dura mater
It is fixed on pedestal, completes autologous dural repairing, after Flexible latch system is absorbed by the body, positioned at the people of base bottom surface
Together with work cerebral dura mater will coincide automatically with the autologous cerebral dura mater positioned at base top surface.
The fixing line for suspending identical cerebral dura mater system automatically in midair is additionally provided with the middle part of the connection shaft.Due to whole lock
Button system is flexiblesystem made by resorbable material, can arbitrarily bend and possess sufficiently ductile not easy fracture, therefore repairing
When mending than larger cerebral dura mater, need to arrange fixing line, whole automatically identical cerebral dura mater system is suspended on skull, prevent hard
Meninges are 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 pedestal and it is distributed in the both sides of connection shaft.When drain is needed, drainage tube can draw from flap valve, without drain
When, flap valve is in closed state.
The torsion spring is made using medical titanium bar.
Compared with prior art, its advantage is the present invention：
By two semi-circular jig arm, by positioned at the artificial dura mater of base bottom surface and the autologous hard brain positioned at base top surface
Film is snapped together, as pedestal and hemispherical locktabs are absorbed by the body, realize artificial dura mater and it is autologous it is dural automatically
It coincide, greatly shortens operation time, reduce operation risk, postoperative complication is reduced, while artificial dura mater position
Protective layer is formed between cerebral tissue and fastener system, injured brain tissue and neural blood vessel in operating process is prevented.
