The present invention aims to provide a reverse retaining implant with micro-vibrating bone stimulation, comprising a main body having a serrated outer surface, the main body internally having a hollow space, the main body being sectioned with at least two elastic retaining units relative to the hollow space, so that a fixation frame structure may be defined by said main body each of the elastic retaining units comprises one or more elastic retaining plates each having a connecting end opposite to the first end portion for connection with the main body or for interconnection, and a free end opposite to the second end portion, with each free end being protruded from the outer surface of the fixation frame, so that a movable reverse retaining portion, which has a low-to-high convex shape for performing micro-vibrating bone stimulation, is formed between the connecting end and the free end. Accordingly, this invention allows each movable reverse retaining portion to vary its abutment with the inner surface shape of different vertebral or small joints so as to produce micro vibrations for stimulating bone hyperplasia of vertebral or small joints, while achieving a better reverse retaining effect for the implant to be more stably positioned at the implantation site without the risk of prolapse.本發明係在於提供一種具微動骨刺激之逆向卡止植入物,其包含一外表面具有齒面的本體,該本體內部具有一空心空間,該本體相對該空心空間剖設至少二個彈性卡固單元,以由該本體形成一固定框架結構,各彈性卡固單元包含一個或多個彈性卡板組成,各彈性卡板具有一相對第一端部以連結本體或相連接的連結端,以及一相對第二端部的自由端,且各自由端係凸出於本體固定框架外表面,以由連結端及自由端之間形成一前低後高凸面狀具微動骨刺激的活動逆向卡固部。據此,本發明藉由各活動逆向卡固部可隨不同椎體或小關節之內表面形狀變化頂抵,以產生微動刺激椎體、小關節之骨增生,又能達到較佳逆向卡固作用使更穩固定位於植入處無脫出之虞。10‧‧‧植入物11‧‧‧本體12‧‧‧上表面13‧‧‧下表面14‧‧‧第一端部15‧‧‧第二端部16‧‧‧空心空間17‧‧‧通孔20‧‧‧彈性卡固單元19‧‧‧融合孔A‧‧‧剖溝21‧‧‧彈性卡板211‧‧‧連結端212‧‧‧自由端213‧‧‧活動逆向卡固部
