    摘要： A wound bed preparation device for delivering a fluid jet to tissue includes a handpiece having a deck height in the range of −0.0254 mm to 0.2032 mm, a channel width in the range of 0.8636 mm to 1.1684 mm, and a nozzle diameter in the range of 0.10668 mm to 0.12192 mm. The handpiece may have a constant channel width over a majority of a tissue impacting section of the handpiece.

    摘要： Techniques are described for making one-piece tubes for surgical instruments in which an inner tube that carries a cutting implement is disposed for movement within an outer tube having a cutting window that exposes the cutting implement to tissue. Swaging is performed to close an end of a tubular member that is to serve as either the inner tube or the outer tube. Other processing steps are also performed. For example, a selected amount of a protrusion formed by the swaging is cut away, the tube material is fused together at a seam formed by the swaging, and the closed distal end of the tubular member is formed into a selected shape. For example, the selected shape is rounded so that the distal end defines convex (e.g., substantially hemispherical) interior and exterior distal surfaces. This renders the tube suitable for use in full-radius surgical instruments. Alternatively, the selected shape is flattened so that the distal end defines flattened interior and exterior distal surfaces. In this case, the tube can be used in end cutting surgical instruments.

    摘要： A surgical instrument comprises an inner tube which rotates within an outer tube and carries a surgical tool that includes a burr for cutting tissue exposed to the burr through an opening in the outer tube. The instrument includes several features which enhance the efficiency at which tissue fragments severed by the burr are aspirated through the inner tube, and which enable the burr to effectively cut relatively soft tissue as well as harder tissue such as bone. For example, the burr includes a proximal shank having a wall that has an aperture therein with a substantial width relative to an outer diameter of the wall for conveying tissue fragments cut by the burr into an interior chamber of the shank, and thence into a passage in the inner tube. The opening in the outer tube is axially elongated sufficiently to expose a major portion of the aperture. The large aperture and its exposure by the outer tube opening reduce the risk of clogging by admitting larger tissue fragments into the inner tube for aspiration. Additionally, the burr includes a plurality of grooves that are axially elongated and inclined transversely to the flutes, and the grooves define a plurality of axially spaced notches in each of the cutting edges. The notches divide the cutting edges into relatively small segments that produce correspondingly small tissue fragments (even when the burr is used to cut soft tissue) to further reduce the risk of clogging. In addition, the cutting edges are preferably provided with a positive rake that makes the cutting edges sharper and suitable for effectively cutting, rather than tearing or shredding, relatively soft tissue.
