Abstract: Instrument and method for removing material from an intervertebral disc. The instrument includes outer and inner tubular members. The outer tubular member defines a passage and a cutting window. The inner tubular member is coaxially disposed within the passage, and defines a central lumen and a cutting tip. The cutting tip forms an open mouth having a plurality of teeth. Upon assembly, the cutting tip is exposed within the cutting window combining to define a shaving head. A manual decorticating implement is coupled to the outer tubular member and defining a scraping surface. A powered handpiece is coupled to the inner tubular member, and the shaving head is inserted into an intervertebral disc and positioned such that the cutting tip contacts targeted material (e.g., nucleus, annulus and/or end plate). The handpiece is activated to rotate the cutting tip relative to the cutting window. Contacted material is sheared between an edge of the cutting window and the teeth of the cutting tip. The manual decorticating implement is used to remove intervertebral disc material from an end plate.

Abstract: An apparatus for adjusting the relative positions of a first component and a second component of a power tool includes a drive rod which interconnects the first and second component. The drive rod has a plurality of external threads in meshing engagement with a plurality of internal threads located on one of the first and second components. An internally threaded element preferably in the form of a backlash nut is also in meshing engagement with the plurality of internal threads. A biasing member is interdisposed between the internally threaded element and one of the first and second component. In a preferred form, the apparatus is incorporated into a power tool for woodworking or metal forming and is operative for eliminating play in the threaded interconnection of the components which is most evidence upon reversal of movement of the drive rod.

Abstract: A chuck has a spring connection between the nut which rotates to advance or retract the jaws and the control ring or sleeve which the user rotates to operate the chuck. The spring normally transmits tightening or loosening rotation from the sleeve to the nut. When the jaws contact a tool, however, the spring allows the sleeve to continue to rotate even though the nut is stopped by the jaw-tool contact. Continued rotation of the sleeve relative to the nut causes a cam mechanism interposed between these two elements to force the non-rotating nut axially forward. This applies a final tool-gripping force to the jaws.

Abstract: A method for treating a brain tumor includes providing a surgical instrument having an inner member and an outer member. The outer member has a distal region forming a cutting window. The inner member is rotatably received within the outer member, and has a cutting tip that is exposed at the window. The cutting tip and the distal region of the outer member combine to define a cutting implement. An opening is created through the patient's skull to provide access to a brain tumor target site. The cutting implement is delivered through the opening to the target site. The cutting tip is placed into contact with the tumor and operated to cut the tumor. The target site is selectively aspirated to remove cut tumor tissue.

Abstract: A method for treating a body tissue comprises delivering a cutting mechanism of a surgical instrument into proximity to a target portion of the body tissue wherein the cutting mechanism includes a first member defining a lumen and a distal cutting tip. At least the first member is supported, via a coupler, by the handpiece. A fluid pathway extends from the distal cutting tip, through the lumen of the first member, and through an interior of the handpiece for fluid connection to a source of negative pressure. In one configuration, a coupler provides an internally-located aspiration control mechanism including a user interface port exteriorly exposed on the coupler and defining an aspiration control pathway extending from the user interface port to a proximal window of the inner member for communication with the lumen of the inner member. With the distal cutting tip placed into contact with the target portion, the treatment site is selectively aspirated by manipulating a position of a finger relative to the user interface port to manually effectuate an altering of a level of vacuum applied by the source of negative pressure at the distal cutting tip.
