An implant to be fastened to a tissue, a tool and a kit. The implant (1) has a first end (5), a second end (6) and an elongated shank (8) made at least partly of a first polymer material. The implant (1) comprises a contact surface for receiving external mechanical energy for deforming the shape of the implant (1) such that the shape of the implant (1) can be deformed and locked in the tissue by the effect of said mechanical energy.一種被鎖附於一組織之植入物、工具及組件。植入物(1)具有一第一端(5)、一第二端(6)及由至少部份的一第一聚合物材料所製成之一延長柄(8)。植入物(1)包括用來接收外部機械能量以使植入物(1)之形狀變形之一接觸表面,如此一來,植入物(1)之形狀藉由機械能量之效應能被變形與被鎖固於組織之中。2...平板3...骨組織、骨頭、頭蓋骨4...工具、工具體10...銷
