Abstract:
An elongate element for transmitting forces during drilling of a bone marrow cavity comprising:a tubular body extending along a longitudinal axis, said tubular body having a plurality of slots each open to an outer diameter (D) of the tubular body and extending in a plane transversally to the longitudinal axis, said slots grouped in repeating angularly offset patterns of more than two slots, the angularly offset patterns repeating at least several times along the longitudinal extent of the tubular body each of said slots cut through a wall of said body, each of said slots spaced along said axis from adjacent slots a distance of between >5% and <40% of the tube outer diameter (D) and said more than two slots of said repeating pattern being angularly offset from adjacent slots at an angle of between 20Â° and <180Â° and connected to the adjacent slots by web regions and each of said slots extend transversely into the body with a depth (T) of <90% of the tube outer diameter (D).
