Publication number: 20140324106Abstract: An implanting apparatus and an operating method thereof are provided. An implanting apparatus used for implanting an intervertebral cage into a location between two adjacent vertebral bodies, wherein the implanting apparatus comprises a sleeve and an extension member. The extension member has a rod and a coupling column, wherein the rod is screwed inside the sleeve, the coupling column is connected to one end of the rod and exposed outside the sleeve, and the axial direction of the coupling column is substantially perpendicular to that of the rod. When one end of the coupling column is disposed on an inner arc surface of a connecting portion of the intervertebral cage and the rod is rotated with respect to the sleeve, the distance between the coupling column and the sleeve is decreased so as to clamp the connecting portion of the intervertebral cage between the coupling column and the sleeve.Type: ApplicationFiled: July 11, 2014Publication date: October 30, 2014Applicant: WILTROM CO., LTD.Inventors: Yang-Hwei TSUANG, Huang-Chien LIANG, Chang-Jung CHIANG, Chia-Hsien CHEN, Fon-Yih TSUANG, Yung-Fang TSAI
