Scie sagittale chirurgicale permettant d'actionner une lampe de scie à tête oscillante, la scie disposant d'un ensemble de couplage pour fixation amovible de la lampe de scie
A surgical saw for use with a blade assembly (52, 702) having a blade bar (494, 494a), two drive rods (74, 74a) movably disposed with and a blade bar and a blade head (76, 76a) that is oscillated by the at least one drive rod is described. The surgical saw comprises a housing (54) including a head (68, 68a), the head having an exposed planar surface (138) to which the blade assembly blade bar is mountable, a motor (60) disposed in the housing and an oscillating drive assembly mounted to said housing head that includes two drive members (72, 72a, 72b). Each of the drive member is movably mounted to said head and extends above the planar surface. Each of said oscillating drive member is shaped to receive the respective drive rod of the blade assembly, wherein said oscillating drive assembly is connected to said motor and configured to, upon actuation of the motor, oscillate said drive members so that the oscillation of each of the drive members results in the reciprocation of the corresponding drive rod. A coupling member (428) separate from the oscillated drive assembly is movably mounted to the housing head so as to extend above the planar surface. Said coupling member is shaped to extend at least partially over the blade assembly blade bar and has a run state in which said coupling member presses against the blade bar to hold the blade bar to the saw head planar surface and a load state in which the coupling member allows the insertion/removal of the blade bar from the saw head planar surface. A manually actuated control member (448) is movably attached to the housing head and connected to said coupling member for moving the coupling member between the locked and load states.
