摘要:
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).
摘要:
Outillage pour effectuer des saignées d'encastrement de câbles électriques, de petites gaines ou de tuyauteries dans des cloisons légères ou dans des panneaux d'isolation thermique appliqués contre les murs d'habitations ou de locaux divers. L'invention consiste à adapter sur une scie sauteuse un porte-outil (3)(4) et (5) permettant la fixation de deux lames de scie (6) à des écartements prédéfinis. Un guide cylindrique (17) appliqué contre l'arrière de ces 2 lames assure leur position verticale et leur écartement lors de la découpe. La profondeur de coupe est obtenue par le réglage en hauteur d'une semelle (12) par l'intermédiaire de son support (11) articulé sur un axe (13) et maintenu en position par le serrage d'un axe boulon (14) coulissant dans les lumières du support (10) fixé sur le châssis de la scie sauteuse par 2 vis (18).
摘要:
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).
摘要:
Apparatus for converting between rotary motion and linear motion includes a rotatable piece being rotatable about an axis; at least one member having a linking surface facing the rotatable piece and arranged for movement relative to the axis of the piece; and a means for linking the linking surface of the respective member and the surface of the rotatable piece, so that rotational motion of the rotatable piece causes linear movement of the at least one member, and/or linear movement of the at least one member causes rotational motion of the rotatable piece. A sawing device may include said apparatus for cutting by repetitive reciprocating cutting action. A saw blade may be configured for such a sawing device.

Cutting tool comprising a structural member (1, 1') provided with means (301, 401 ) for engagement with operating means, and a plurality of cutting edges (201, 201') connected to said structural member (1, 1'), intended to follow a given cutting path; said cutting edges (201, 201') are each connected to said structural member (1, 1') by means of a suitable support part (101, 101') connected at one end to said structural member (1, 1'), oriented in a manner substantially perpendicular to the plane of said cutting path and having said cutting edge (201, 201') at its free end, the cutting edges (201, 201') connected to two adjacent support parts being arranged in substantial opposition to each other with respect to said cutting path.
