摘要： 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.

The surgical saw comprises a housing (54) including a head (68, 68a) that extends from said housing for receiving a blade assembly (52, 702) having a blade bar (494, 494a) and two drive rods (74, 74a) moveably disposed within the blade bar and a blade head (76, 76a) that is configured to be oscillated by said two drive rods. The surgical saw further comprises two oscillating drive members (72, 72a, 72b) that extend outwardly from the housing head, each of said oscillating drive members are shaped to be connected to the corresponding drive rod so that the oscillation of the respective drive member results in the reciprocation of the corresponding drive rod. The surgical saw further comprises an oscillating drive assembly (240, 242, 418, 608, 616, 694) disposed in said housing that is configured to receive a rotational moment and convert the rotation moment to a motion that oscillates said oscillating drive members.Tthe oscillating drive members are mounted to said housing so as to engage in a first oscillating motion and in a second translation motion wherein, in the translational motion. The oscillating drive members move the blade assembly coupled thereto between a first position relative to the housing head and a second position relative to the housing head. The surgical saw further comprises at least one bracket (146, 148, 578) attached to the saw head. Said bracket positioned so that, when the oscillating drive member locates the blade assembly in the first position, the blade assembly is spaced from the bracket and, when the oscillating drive member locates the blade assembly in the second position, the blade assembly abuts the bracket.

摘要： A surgical saw blade is described comprising an elongated blade bar having opposed plates. The blade bar has opposed proximal and distal sections, with the proximal section having a feature for releasably holding the blade bar to a powered surgical sagittal saw. The blade bar plates are spaced apart from each other so as to form in the blade bar distal section a void space and a primary opening into the void space. A blade head of the surgical saw blade has a base disposed in the blade bar distal section opening that is pivotally mounted in the blade bar distal section void space, and a crown integral with the base that extends through and outside of the blade bar distal section primary opening, the crown being formed with teeth, wherein a thickness of the crown is greater than a thickness of the base to allow the insertion of the blade bar into a kerf cut by the blade head. At least one drive rod is provided and adapted to pivot the blade head. The blade head base is formed with a through window and a support member extends between the blade bar plates through the void space defined by the plates and through the blade head base window.

摘要： A surgical saw blade (702) comprising an elongated blade bar formed from lower and upper plates (502a,504a), respectively, is described. The blade bar has opposed proximal and distal sections and a longitudinal center axis that extends between the proximal and distal sections. The proximal section has a proximal end (720) of the blade bar and a feature for releasably holding the blade bar to a powered surgical sagittal saw. The distal section is formed with a void space and a primary opening into the void space, wherein the blade bar plates are spaced apart from each other so as to form in the blade bar distal section the void space. A blade head has a base (496a) disposed in the blade bar distal section void space that is pivotally mounted in the blade bar distal section void space. At least one drive rod (74a) has a distal end moveably attached to the blade head base and a proximal end adjacent blade bar proximal section. The proximal end is adapted to be attached to a drive member integral with the surgical sagittal saw. The blade bar is further formed so that the proximal section has opposed side edges (722) that extend forward from the blade bar proximal end, wherein at least one of the side edges tapers outwardly relative to the longitudinal center axis of the blade bar. Forward of the blade bar proximal section having the outwardly tapered side edge the blade bar is formed so that the distal section has a constant width.

摘要： A surgical saw blade (52, 5a, 52b, 702) is described. The surgical saw blade comprises an elongated blade bar (494, 494a, 494b) having opposed plates (502, 502a, 504, 504a). The blade bar has opposed proximal and distal sections. The proximal section has a feature (516, 538) for releasably holding the blade bar to a powered surgical saw (50). The distal section is formed with a void space and a primary opening into the void space, wherein the blade bar plates are spaced apart from each other so as to form the void space in the blade bar distal section. The surgical saw blade further comprises a blade head (76, 76a), the blade head having a base (496, 496a) disposed in the blade bar distal section opening that is pivotally mounted in the blade bar distal section, and a crown (498) integral with the base that extends through and outside of the blade bar distal section primary opening, the crown being formed with teeth (499, 499a), wherein the base and the crown both have a thickness and the thickness of the crown is greater than that of the base to allow the insertion of the blade bar into a kerf cut by the blade head. In addition, the surgical saw blade comprises two drive rods (74, 74a). Each of said drive rods has a distal end movably attached to the blade head base and a proximal end adjacent blade bar proximal section, the proximal end configured to engage a drive member integral with the surgical saw. Each of the opposed blades proximal to its distal end has a pair of oval-shaped openings (520, 520a, 539, 539a) of one size and positioned to be aligned with each other. Each of said two drive rods has a pair of overlapping fingers (558, 558a) extending forward therefrom and over the blade head base. Each pair of said fingers are configured to pivotally connect the respective drive rods to the blade head base and each pair of said fingers are disposed in the corresponding pair of the aligned oval-shaped openings.
