そのうえ、固定方法もワイヤー固定のため十分な固定が
得られないことなどもあり、術後、第６図に部分断面を
示すように人工頭蓋骨部材Ａが陥没するなど、完全に再
現できないという欠点があった。As described above, when prostheticly repairing a defect with autologous bones and other prosthetic materials, the shape of the defect is deformed after treatment even with autologous bone, or even if other prosthetic materials are used, the original skull bone is used. It is difficult to reproduce the shape of
In addition, since the fixing method cannot be sufficiently fixed because the wire is fixed, there is a drawback that the artificial skull member A is depressed as shown in the partial cross section in FIG. 6 and cannot be completely reproduced. there were.
上記の如き、問題点に鑑みて、本発明では、人工頭蓋
骨部材の骨との接触部分である外周部に係止部を設け、
陥没を防止することを特徴とする。As described above, in view of the problems, in the present invention, the locking portion is provided in the outer peripheral portion which is the contact portion with the bone of the artificial skull member,
It is characterized by preventing depression.
以下、図によって本発明の実施例を具体的に詳述す
る。Embodiments of the present invention will be specifically described below with reference to the drawings.

部材１を選択したり、あるいは不適合な部位の天然頭蓋
骨を削って整形して最もよく合致した状態のもとに人工
頭蓋骨部材１でもって閉蓋する。FIG. 1 shows an artificial skull member 1 according to the present invention. The artificial skull member 1 is a ceramic material such as alumina or apatite, or a metal material such as stainless steel, Co-Cr-Mo alloy, pure titanium or titanium alloy. However, it is also possible to make various kinds of metal materials coated with alumina, apatite, TiO 2 , TiN, etc. in advance to match the shape when the skull is cut off, and cut out the part The artificial skull member 1 best suited to the shape is selected, or the natural skull member at the incompatible portion is shaved and shaped to close the artificial skull member 1 with the artificial skull member 1 in the best fitted state.
この人工頭蓋骨部材１は頭の丸味形状により一層適合
性をよくするように球殻状を成すとともに周縁部の所要
箇所には一体的に複数個の突出部２が、形成してある。The artificial skull member 1 has a spherical shell shape so as to better adapt to the rounded shape of the head, and a plurality of projecting portions 2 are integrally formed at required portions of the peripheral edge portion.
さらにこの突出部２は、第２図（イ）（ロ）にて部分
断面を示したように天然頭蓋骨Ｂ上に載置した状態のも
とに係止され、人工頭蓋骨部材１が骨膜下（脳室内）中
へ陥没することが防止される。Further, the projecting portion 2 is locked under the state of being placed on the natural skull B as shown in the partial cross section in FIGS. 2 (a) and (b), and the artificial skull member 1 is subperiosteal ( Depression is prevented.
なお、突出部２の下面は段部2aを形成したものであっ
てもよいが、これに限らず第３図に示すようにテーパ面
2bとしておくことによって開頭切除部に対する人工頭蓋
骨部材１の位置決めがいっそう容易となり、かつ安定的
に装着固定することができる。The lower surface of the protruding portion 2 may have a stepped portion 2a, but the present invention is not limited to this. As shown in FIG.
By setting it as 2b, the positioning of the artificial skull member 1 with respect to the craniotomy part can be further facilitated, and the artificial skull member 1 can be stably mounted and fixed.
さらに、第４図に示した如く、突出部２を若干長く、
しかもＶ字状溝2cが形成してあることによって不要な先
端部を折り去ることによって最適の長さの突出部２に調
整することができる。Furthermore, as shown in FIG. 4, the protrusion 2 is slightly longer,
Moreover, since the V-shaped groove 2c is formed, the unnecessary tip portion can be folded off to adjust the protrusion 2 to the optimum length.
叙上のように、本発明によれば、腫瘍や、外傷などに
より生じた頭蓋骨欠損部に、人工頭蓋骨を挿入すること
により、患者、本来の顔面形状を再現することができ、
その人工頭蓋骨に複数の突出部を設けたことにより、従
来のワイヤーなどによる固定法で問題となっていた陥没

美性を損なうことなく頭蓋骨を再建することができ、人
類福祉にとって寄与するところは大である。As described above, according to the present invention, a tumor, a skull defect caused by trauma, by inserting an artificial skull, the patient, it is possible to reproduce the original facial shape,
By providing multiple protrusions on the artificial skull, it is possible to fix without causing depression, which has been a problem with conventional fixation methods using wires, etc., and the skull can be reconstructed without impairing the aesthetic satisfaction of the patient. There are many places where people can do and contribute to human welfare.
