Abstract:
1. A bone reaming device comprising: a first shaft extending along an axis; a head having an outer surface, which head is rotatably mounted on the first shaft; an ablation device, the ablation device being movable with respect to the head and being capable of protruding at least partially beyond the surface of the head, and a third shaft, the third shaft being axially movable and coupled to the ablation device via a gear, wherein the gear includes a gear wheel portion rotatable about an axis perpendicular to the longitudinal axis of the device, the gear capable of being actuated to modify a variable geometry of a protruding amount of the ablation device, wherein the protruding amount of the ablation device is variable by using a remote actuation device so that the variable geometry of the protruding amount is remotely modifiable, wherein the ablation device comprises at least one ablation element protruding at least partially beyond the surface of the head through a through hole within the head, wherein the ablation element comprises a hinge having a rotational axis being perpendicular to the axis of the gear wheel portion.
