摘要：The present invention concerns a device for sectioning a vertebral lamina, characterized in that it comprises a base (4) for positioning the device and protecting the medullar canal when sectioning the lamina, sectioning means (1) slide-mounted in the base (4) along a first axis (A1), a first piston slide-mounted in a sleeve (10) of the sectioning means (1) along a second axis secant to the first sliding axis (A1) of the sectioning means, a second piston (3) made integral with the first piston (2) and slide-mounted in the base (4) along a third axis (A2), the sectioning means (1) being provided with a cutting element oriented in opposite direction to the second piston (3) with respect to the sleeve (10), and the sliding of the second piston (3) along the third axis (A2) causing the sliding of the sectioning means (1) along the first axis (A1) via the first piston (2).
