Abstract:
1. A device for sectioning a vertebral lamina comprising: a longitudinal plane of the device and first, second, and third axes, none of which axes are parallel or collinear and all of which axes lie in the longitudinal plane of the device; a base adapted to position the device and protect the medullar canal when sectioning the lamina; a sectioning component mounted in the base and adapted to slide linearly along the first axis, the sectioning component comprising a sleeve through which passes the second axis and a cutting element distal from the sleeve and lying within the longitudinal plane of the device; a first piston mounted in the sleeve with a longitudinal axis of the first piston adapted to slide linearly in the sleeve along the second axis, which sliding induces linear sliding of the sectioning component in the base along the first axis; and a second piston attached to the first piston opposite the sectioning component and adapted to slide linearly in the base along the third axis, which sliding induces linear sliding of the first piston in the sleeve along the second axis.
