| 摘要 |
The invention relates to an expandable implant (11) with an upper plate (12) and a lower plate (16) which extend in the xy plane, which serve for anchoring on/in the vertebral support surfaces, and at least three gears (20, 25, 30) which are coupled to each other, wherein the gears (20, 25, 30) serve to expand the implant (11), and each gear (20, 25, 30) has a threaded spindle (21, 25, 31) and a threaded sleeve with corresponding inner thread (22, 27, 32), wherein the pitch of one thread (31, 32) is different from the pitch of the other threads (21, 22; 26, 27). The invention also relates to an operating instrument (80) for this implant. |
