The drill tool for lifting the sinus, in which a sinus membrane inside an alveolar bone is lifted after the alveolar bone is perforated for a placement of an implant, includes a perforating drill to perforate the alveolar bone up to a part adjacent to the sinus membrane, the perforating drill including: a perforating body which includes a first end part provided with a cutter for perforating the alveolar bone and a second end part formed with a through hole and a perforating rod which couples with the perforating body to move close to and apart from the first end part of the perforating body toward the through hole of the perforating body and adjusts a perforation depth when perforating the alveolar bone.本發明揭露一種用於頂起鼻竇(sinus)之鑽孔工具,該鑽孔工具在將一齒槽骨(alveolar bone)穿孔後頂起該齒槽骨內之一鼻竇膜(sinus membrane)以供置入一植入體,該鑽孔工具包含一穿孔鑽具,用以將該齒槽骨穿孔直到鄰近該鼻竇膜之一部分,該穿孔鑽具包含:一穿孔本體,其包含一第一端部和一第二端部,該第一端部設置有用於對該齒槽骨穿孔之一切削刀,該第二端部形成有一貫穿孔;以及一穿孔桿,其與該穿孔本體相耦合,以朝該穿孔本體之該貫穿孔靠近及遠離該穿孔本體之該第一端部移動,並在對該齒槽骨穿孔時調整一穿孔深度。200...穿孔鑽具210...穿孔本體211...切削刀217...容納部219...排出孔230...穿孔桿231...外螺紋部233...平坦部235...連接凹槽250...緊固單元252...外螺紋254...六角孔
