a handle at a proximal end of the tool;

an elongate member extending from the handle to a distal end of the tool; and

a saw at the distal end of the tool, the saw being supported by the elongate member, wherein the saw includes an oscillating saw blade that is oscillated by energy transferred along the elongate member via a rotating shaft, with oscillating movement of the saw blade being generated via an offset pin protruding from an end of the shaft at a distal end of the elongate member, wherein the offset pin is coupled to the saw blade via a connector with a slot extending perpendicular to the shaft, such that rotation of the shaft rotates the pin to move the pin up and down the slot while the slot oscillates side-to-side, resulting in an oscillating movement of the connector,

wherein the tool is arranged for insertion of the saw into the body during keyhole surgery, and

wherein the saw is able to cut bone when pressed against the bone.
