    摘要： A tool is disclosed, for taking a biopsy sample, having a needle attached to a syringe, with an opening in the side of the needle, which can be selectively covered by a cannula slidably mounted over the needle. The cannula can be locked into place on the needle, and the plunger of the syringe can be spring loaded to draw a sample into the syringe upon release of a latch. A method is also disclosed for taking a biopsy sample by sliding a cannula over a needle, inserting the cannula and needle into the tissue to be sampled, partially withdrawing the cannula from the needle to expose a lateral opening in the needle, maneuvering a sample of the tissue into the opening, cutting the sample from the tissue, and drawing the sample out through the needle.

    摘要： Prosthetic apparatus for promoting and supporting guided bone tissue regeneration in at least missing or excised portions of the human mandible or maxilla and in bony defects of the mandible and maxilla. The apparatus includes a bone attachment tray formed of tissue-biocompatible titanium sheet material having perforations therethrough for receiving bone screws to affix the tray to stump portions and ridge sections of the mandible or maxilla proximate the missing or excised stump portions or ridge sections and one or more tissue-biocompatible metallic dental tooth root replacement implants which are releasably affixed at one end to the inner surface of the tray and which depend from the tray into the missing or excised portions or bone defects of the mandible or maxilla for incorporation and support in bone tissue regenerated within the tray. The inner surface of the attachment tray may have affixed thereto one or more layers of a biologically and chemically inert microporous membrane sheet material to promote the guided tissue regeneration of replacement bone within the tray and protect the space thereunder from the entry of unwanted bacteria and competitive tissues during the healing and bone regeneration period.

    摘要： A fastener with a recessed drive socket and a driving tool with a cooperable driving head. The socket having a cylindrical interior wall interrupted by a plurality of driving corners. The driver having a tapered driving head including a plurality of sharpened driving edges adapted to engage the driving corners. The tapered driving end may be axially forced into the driving socket such that the plurality of driving edges frictionally engage the driving corners to hold the fastener on the driver and to enhance torque transmission. The cylindrical walls of the socket and the walls of the driver bit between the driving edges cooperate to define a fluid channel for passage of fluid around the driving head during positioning within the socket.

    摘要： A biocompatible cranioplasty plate structure, and method of its installation, for use in the surgical repair and recontour of large cranial defects of the human skull created or caused by injury, surgical intervention for tumor removal, or congenital anomaly or disease. The plate structure is formed from a sheet of pliable perforated metallic material, particularly commercially pure titanium or titanium alloy material, and is of generally elliptical configuration with a central preformed arcuate and convex area matching the compound and complex curvature of the forehead, side or rear areas of the typical human adult skull. The plate structure includes adjustable peripheral panels for bending fitment and close adaptation of the plate structure to intact cranial bone of the skull adjacent to and surrounding the defect and for attachment of the plate structure to intact bone by bone screws having low profile heads and applicable through perforations of the peripheral panels. The perforated metallic sheet material may be a mesh material having parallel rows and perpendicularly arranged parallel lines of square or circular holes. Alternatively, the perforated metallic sheet material may be a gridwork including legs which define repeating patterns of rectangular or triangular open spaces.
