This creation is a kind of psoralen unit and combined psoralea； the psoraea unit is a plate body, which includes two opposite sides and an outer ring wall surface, and the outer ring wall surface is connected between the two sides； the plate is along the outer ring The wall surface is formed with a plurality of joint pillars and a plurality of joint grooves, and the shapes of the joint pillars and the joint grooves correspond to each other； the combined bony plate is a foldable plate body, which includes a plurality of mutually connected bony plate units, and any two connected bones In the bone piece unit, the binding column of one of the bone piece units is inserted in the binding groove of the other bone piece unit； by combining a plurality of small bone piece units and bending them to the shape of the skull defect site The matching large combined bone filling tablets can avoid material waste caused by cutting processing of expensive medical materials, and can also save manufacturing time.本創作係一種補骨片單元及組合式補骨片；補骨片單元為一板體，包含相對兩側面及一外環壁面，外環壁面連接於兩側面之間；板體上沿外環壁面成形有複數結合柱及複數結合槽，結合柱及結合槽的形狀相對應；組合式補骨片為可彎折的板體，包含複數相互連接的補骨片單元，任兩相互連接的補骨片單元中，其中一補骨片單元的結合柱穿設於另一補骨片單元的結合槽內；藉由以許多小塊的補骨片單元組合並且彎折成與顱骨缺損部位的形狀相吻合的大塊組合式補骨片，以避免對昂貴的醫療材料進行切削加工造成的材料浪費，並且也可節省製造時間。
