摘要： Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.

摘要： A cutting tool includes a generally cylindrical body, a plurality of cutting teeth formed on the generally cylindrical body, a plurality of non-cutting protrusions formed on the generally cylindrical body, and a plurality of gullets formed on the generally cylindrical body. Each gullet is formed between one of the plurality of cutting teeth and one of the plurality of non-cutting protrusions. Each gullet has a base and a gullet depth measured from the base to a tip of a corresponding cutting tooth. Each non-cutting protrusion is located approximately halfway between the tips of two adjacent cutting teeth and has a height that is at most about 75% of the gullet depth.

摘要： A drill bit which is rotatable about a drilling axis is disclosed. The drill bit has a drill shaft section having a first plug-connecting element and a cutting section having a second plug-connecting element. The first plug-connecting element and the second plug-connecting element form a plug connection. The cutting section includes a plurality of cutting subsections each having a ring subsection and at least one cutting segment, wherein each ring subsection together with the first plug-connecting element forms the plug connection and is connectable to the first plug-connecting element by a pin connection.

摘要： A hole saw includes a cylindrical body disposed along an axis of rotation with a side wall extending axially from a cap end to a cutting end. The cutting end includes a plurality of cutting teeth. The hole saw also includes a cap coupled to the cap end of the cylindrical body. The side wall defines an elongated aperture configured to receive a tool for removing work piece plugs from within the cylindrical body. The elongated aperture has a first slot portion adjacent the cutting edge. The first slot portion is oriented perpendicular to the axis of rotation. The elongated aperture also has a second slot portion connected to the first slot portion and extending from the first slot portion toward the cap end. The second slot portion is oriented at an oblique angle relative to the axis of rotation.

摘要： A recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth suitable for abusive cutting applications. The two consecutive teeth, which may be bi-metal, include a high tooth and a relatively low tooth in comparison to the high tooth. Each high tooth and low tooth include a primary clearance surface defining a relatively shallow primary clearance angle that is about 28° or less, and a secondary clearance surface defining a relatively steep secondary clearance angle in comparison to the primary clearance angle. The primary clearance angle of the high tooth is steeper than the primary clearance angle of the low tooth, such as between about 23° and 28°, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.

摘要： A hole saw having a blade portion separable into two parts which when separated form a base portion and a tip portion. The base and the tip have correspondingly shaped apertures and lugs that co-operate together to hold the blade tip in place. A locking means further assists in ensuring that the blade tip remains locked to the base and includes a sliding latch that engages an aperture in the blade and the base and is itself locked in place to thereby lock the blade to the base. An intermediate portion also allows for the hole saw to drill through different depths
