Title
(EN) SAW-BLADE FOR SAWING LIVING HUMAN BONE
(FR) LAME-SCIE POUR SCIER L'OS HUMAIN VIVANT
Abstract
(EN)
This invention relates to a saw-blade for sawing living human bone at surgical operations, said 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 portions (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).
(FR)
Cette invention concerne une scie-lame permettant de scier l'os humain vivant lors d'opérations chirurgicales. Ladite lame-scie (1) présente sur au moins un côté (10) au moins deux parties de scie (8, 9), ladite lame-scie (1) comportant au moins un espcace intérieur (14) à travers lequel un liquide de refroidissement (18) est adapté pour s'écouler et refroidir la lame-scie (1) pendant le sciage. Pour permettre un refroidissement efficace direct des parties de scie (8, 9) et leur nettoyage continu pendant le sciage l'espace (14) s'étend jusqu'aux deux parties de scie (8, 9) et est ouvert entre elles afin d'une part de conduire le liquide de refroidissement (18) jusqu'aux parties de scie (8, 9) pour les refroidir, et d'autre part de faire émerger ledit liquide de refroidissement (18) entre les parties de scie (8, 9) afin d'entraîner les résidus osseux ou les autres résidus se trouvant sur la scie, à l'opposé des parties de scie (8, 9).
