    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 powered tool (20) for performing surgical procedures. The tool (20) includes a handpiece (22) in which a power generating unit (26) is housed. A control member is mounted to the handpiece (22). The control member (38) is mounted to the handpiece (22) so that the orientation of the control member (38) can be selectively set relative to the point to which it is mounted to the handpiece (22) and so it can move relative to a reference point on the handpiece. A control module (36) monitors the orientation of the control member (38) and its position relative to the reference point. Based on the control member (38) orientation and position, the control module (36) generates signals to regulate the operation of the power generating unit (26). When the power generating unit (26) is a motor, the control module generates signals to ensure that the maximum speed at which the motor can be driven is less than the no load speed.

    摘要： A surgical system for performing spine surgery. The system comprises a retractor that may be positioned within a patient to facilitate maintaining a volume of fluid at a surgical site. The retractor includes an opening capable of receiving one or more surgical instruments, for example, a cutting instrument and an endoscope. A cutting member of the cutting instrument may be submerged and operated within the volume of fluid to resect tissue, for example, within the intervertebral disc space. The volume of fluid maintained at the surgical site improves cooling of the surgical site and visualization of the surgical site via the endoscope during resection. The volume of fluid is maintained at the surgical site via the surgical system. The surgical system includes a sensor for measuring the level of fluid in the retractor, an inflow source and an outflow source having an outflow sensor and being in fluid communication with the retractor, and a controller controlling the surgical system.

    摘要： A rongeur (34) for driving a cutting unit (240) that includes an outer (240) tube and a cutting implement (302) able to both rotate in move longitudinally in the outer tube The rongeur includes a body (36) to which a rotating spindle (102) for actuating the cutting implement is mounted. The spindle is designed to allow the inner tube to while, rotating move longitudinally relative to the spindle. A mechanism (150, 180) attached to the body selectively displaces the drive inner tube so the distal end of the cutting implement can be advanced towards and retracted away from the distal end of the outer tube.

    摘要： A surgical tool system (20) with replaceable surgical cutting accessories (26) and attachments (34) for holding the tools. This system includes a handpiece (22) to which the cutting accessory and attachment are releasably attached. Collet (50) located inside a drill housing (44) located at one end of the handpiece securely fastens the surgical tool to a motor (24) also located in the handpiece. Leaf spring assembly (46) flush with the drill housing releasably secures the attachment in place. A single actuating collar (52) located around the outside of the drill housing both controls the locking force supplied by the collet and selectively relaxes the leaf spring assembly.
