A kind of artificial skull structure with hole slot

Technical field

The utility model relates to medical material field more particularly to a kind of artificial skull structures with hole slot.

Background technique

Cranioplasty be for skull defeci and a kind of common operation of neurosurgery that head is repaired, solve Defective region not to the effective protection of brain tissue and blood supply disorder, cerebrospinal fluid circulation is abnormal the problems such as, it is also necessary to solve shape The problems such as Plastic recovery.The presently used material for repairing skull arrived, some has vertically or favours the logical of surface in structure Hole, for the circulation of blood inside and outside skull liquid such as (and or) cerebrospinal fluid, flushing liquor, diffusate, secretion, or suspention dura mater or Pseudomembrane.In patient's daily life, external sharp object may directly through this vertical or inclined through-hole, cause encephalic The damage of structure and tissue.

Utility model content

For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of artificial skull knot with hole slot Structure can directly pass through hole slot to avoid sharp keen foreign object and hurt Intracranial structure and tissue.

The purpose of this utility model is implemented with the following technical solutions:

A kind of artificial skull structure with hole slot, it is described artificial including the artificial skull that the defective region with skull matches Skull has inner surface and the outer surface opposite with inner surface, has on the artificial skull multiple for for inside and outside artificial skull The hole slot of liquid communication, the hole slot are connected to the inner surface and the outer surface of the artificial skull, and in the inner surface and appearance It is bent and extends between face.

Further, the hole slot edge is arc perpendicular to the artificial skull inner surface or the cross sectional shape in outer surface direction Shape, angular, polygon, planar spiral or stereo spiral shape.

Further, the two neighboring hole slot is mutually indepedent, is overlapped or partially overlaps.

Further, the hole slot is round, ellipse, triangle perpendicular to the hole section of the hole slot extending direction along edge Shape, quadrangle, polygon or polygonal.

Further, the hole slot diameter range is the ㎝ of 1 ㎜~1.

Further, the spacing range of two neighboring hole slot is the ㎝ of 1 ㎜~5.

Further, the material of artificial skull is selected from titanium alloy, polymethyl methacrylate, polyethylene, calcium phosphate or poly- Ether ether ketone.

Compared with prior art, the utility model has the beneficial effects that: providing a kind of artificial skull structure with hole slot, Artificial skull is equipped with multiple hole slots for for liquid communication inside and outside artificial skull, and sharp object can be stopped to pass through hole slot, reduces Intracranial structure or tissue are injured by injury chance.

Specific embodiment

In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

Such as Fig. 1-6, a kind of artificial skull structure with hole slot, the people that the defective region including the skull with head 20 matches Skull 10 is made, artificial skull 10 has inner surface 101 and the outer surface 102 opposite with inner surface 101, has on artificial skull 10 Multiple hole slots 11 for for liquid communication inside and outside artificial skull, the liquid include but is not limited to blood, cerebrospinal fluid, flushing liquor, Diffusate or juice, hole slot 11 are connected to inner surface 101 and the outer surface 102 of artificial skull 10, and in inner surface 101 and appearance It is bent and extends between face 102, convenient for the liquid of skull inner surface 101 and outer surface 102, i.e. blood, cerebrospinal fluid, flushing liquor, infiltration The liquid communications such as liquid, secretion out are also convenient for dura mater and the vacation fixed between artificial skull 10 and brain tissue with materials such as sutures Film is to reduce the probability of hemotoncus formation and promote adhesion, the combination with materials for use in skull-fixing.

As preferred embodiment, hole slot 11 is along section perpendicular to artificial 10 inner surface 101 of skull or 102 direction of outer surface Face shape is not construed as limiting, and sight of being subject to cannot pass through hole slot 11 and see opposite side, can be arc, angular, polygon, plane spiral shell Revolve shape or stereo spiral shape, wherein the cross sectional shape of two neighboring hole slot 11 do not limit it is all identical, for example, see Fig. 4, each The cross sectional shape of hole slot 11 be it is angular, angular to be asymmetric, angular hole slot 11 is in the inner surface 101 of artificial skull 10 and outer Extending direction between surface 102 is inconsistent, correspondingly, the opening of hole slot 11 is straggly to be distributed in artificial 10 inner surface of skull 101 or outer surface 102 on, in other embodiments, it is consistent that the cross sectional shape of the hole slot 11 can be symmetrical and extending direction, And correspondingly, the opening of hole slot 11 is uniformly distributed in artificial 10 inner surface 101 of skull or outer surface 102.The utility model is implemented 10 structure of artificial skull with multiple hole slots 11 in example can stop the sharp objects such as nail, needle directly through hole slot 11, reduce wound The chance that evil Intracranial structure and tissue are injured.

Hole slot 11 is not construed as limiting along the hole section perpendicular to 11 extending direction of hole slot, can be round, ellipse, triangle Shape, quadrangle, polygon or polygonal, in the present embodiment, hole slot 11 is circle along the hole section perpendicular to 11 extending direction of hole slot Shape.

11 diameter range of hole slot is the ㎝ of 1 ㎜~1, and two neighboring hole slot 11 is mutually indepedent, is overlapped or partially overlaps, preferably , two neighboring hole slot 11 is mutually indepedent in the present embodiment, and its spacing range is the ㎝ of 1 ㎜~5, diameter range and spacing range Situations such as not influencing according to the strength of materials of artificial skull 10, thickness and artificial 10 degree firm in structure of skull, is determining, Ying Gen Consider to select suitable materials for use in skull-fixing according to individual patients situation, economy, repairing position etc. factors, in the present embodiment, The material of artificial skull 10 includes but is not limited to titanium alloy, polymethyl methacrylate, polyethylene, calcium phosphate or polyether-ether-ketone Deng.

To sum up, the utility model is convenient for artificial skull using 10 structure of artificial skull with multiple hole slots 11 convenient for drainage The liquid communications such as inside and outside liquid, i.e. blood, cerebrospinal fluid, flushing liquor, diffusate, secretion；Convenient for being fixed firmly with materials such as sutures Film or pseudomembrane reduce hemotoncus and form probability, promotion and materials for use in skull-fixing adhesion and combine；It can stop the sharp objects such as nail, needle Across hole slot 11, injury Intracranial structure and tissue are reduced by injury chance, it is more practical, be more advantageous to protection Intracranial structure and group It knits.

It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims Within the scope of.
