A saw-blade for sawing living human bone during surgical operations, the saw-blade (1) presenting on at least one side (10) at least two saw portions (8, 9) and said saw-blade (1) having at least one inner space (14) through which coolant (18) is adapted to flow for cooling the saw-blade (1) during sawing. For efficient direct cooling of the saw portions (8, 9) and continuous cleaning thereof during sawing, the space (14) extends up to the two saw portion (8, 9) and is open between them in order, on one hand, to conduct coolant (18) to the saw portions (8, 9) for cooling them, and, on the other hand, to cause coolant (18) to emerge between the saw portions (8, 9) for carrying off bone residues or other saw residues in a direction away from the saw portions (8, 9).
A saw blade for sawing living human bone during surgical operations, said saw blade comprising an elongated flattened tube having a substantially rectangular cross section and terminal edges including at least a pair of spaced parallel edges extending along one side of the saw blade, said tube defining a coolant duct terminating at and between said terminal edges over substantially the full length of the terminal edges;
