Assembleable artificial bone plate and artificial bone plate unit in which a large assembleable artificial bone plate having a desired shape can be formed by assembling a plurality of small artificial bone plate units to reduce material waste

The present invention relates to an artificial bone plate unit and an assembleable artificial bone plate. The artificial bone plate unit has a plate body. The plate body has two opposite side surfaces and an outer ring wall. The outer ring wall is connected between the two side surfaces. A plurality of coupling columns and a plurality of coupling grooves are formed on the plate body along the outer ring wall, and the shape of the coupling column corresponds to the shape of the coupling groove. A plurality of drug cavities are formed inside the artificial bone plate unit, and a plurality of drug release openings are formed on the artificial bone plate unit. The drug release openings are in communication with the drug cavities. Through the drug cavities and the drug release openings, the artificial bone plate unit can facilitate wound healing by slowly releasing drugs after surgery. By assembling a plurality of small artificial bone plate units and bending them into a large assembleable artificial bone plate ha
