Abstract: The present invention relates to a surgical drill including a drill member having a cutting section for cutting bone, the cutting section being situated at a distal end of the drill member. The drill member also comprises a non-cutting protection tip for protecting nerves, tissue or dura from being cut. The non-cutting protection tip is situated distally of the cutting section.

Abstract: The invention provides a method of and an apparatus for removing bone, capsule ligaments from a co-operating pair of superior and inferior articulating processes (also called facet joints) of the spine to create a path for postero-lateral endoscopic access to the vertebral foramen and to the epidural space of the spinal canal; successively advancing tools (64) of an increasing diameter along the path; advancing through a working cannula (40) of an endoscope in order to visualize the herniated disc material and to check for the presence of nerve roots or dural sac; and engaging soft tissue with a tool in the working cannula, the soft tissue deriving from the herniated disc, and withdrawing the tissue through the cannula, hereby to relieve pressure on nerve structures within the vertebral foramen and spinal canal.

Abstract: A device for osteosynthesis comprises an elongated bone plate and an elongated slide plate adapted to be fitted on the outside of the bone plate. Several longitudinally spaced elongated holes for the reception of bone screws are provided in one longitudinally portion only of the bone plate, while the other longitudinal portion of the bone plate is provided with circular holes and the elongated slide plate is provided with several longitudinally spaced circular holes. The circular holes in the slide plate have a diameter approximately equal to the width of the elongated holes in the bone plate and a pitch substantially equal to the pitch of those elongated holes.
