    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 surgical tool with links between the distal end of the tool shaft and the working member located forward of the shaft. Steering cables attached to the working member are selectively tensioned and slackened to bend the links. Once the links have desired curvature, a lock assembly tensions the plural cables. The tensioning of the cables urges the links against each other. As a result of the abutment of the links against each other, the links resist buckling from the desired curved shape.

    摘要： A saw (50) for pivoting a blade (52) in a sagittal plane. The saw includes two drive members (96, 114) that displace the blade. One drive member (114) pivotally displaces the blade in the sagittal plane. The second drive member (96) reciprocates the blade along the longitudinal axis of the blade. The drive members displace the blade at different frequencies. Consequently the teeth (186) of the blade travel in a loop (200) pattern that crosses itself.

    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.
