    摘要： A device includes a tubular element, and a cutter spring-biased relative to the tubular element. In an unloaded configuration the cutter is displaced relative to the tubular element by a displacement distance, and when the cutter is in a loaded configuration the displacement distance is reduced. A first structure is longitudinally fixed relative to the cutter and rotationally engaged relative to the tubular element. A length of the first structure extends proximally in the unloaded configuration. A second structure is longitudinally displaceable relative to the first structure. In the loaded configuration, a driver engages and rotates both the first and second structures, and thus the tubular element and cutter together. Once the cutter breaks through the bone, the cutter spring-biased into the unloaded configuration, resulting in disengagement of the first structure from the driver to prevent rotation of either the tubular element or the cutter.

    摘要： Tools and instruments for use in orthopedic applications for forming openings and/or cavities in anatomical structures, e.g., bone and cartilage structures, are provided. The tools/instruments include a shaft having a distal end and defining a longitudinal axis and a shank disposed at the distal end of the shaft. The shank includes a tapered cutting edge and an adjacent fluted region. The shank is effective to collect and deposit materials generated by a cutting action within an opening or cavity formed thereby. A stop may be mounted with respect to the shaft. The tools/instruments deliver a clean and crisp cut to anatomical structures, thereby facilitating interaction with subsequently delivered plugs and/or implants.
