    摘要: A guide sleeve that is deformable or splittable, for use in threading a surgical screw therethrough and into a drilled hole (24) at a surgical site for repair of a fractured bone. The guide sleeve has an inner diameter only as large as the screw shank, not its enlarged head, and the incision need only have a general diameter as large as the guide sleeve outer diameter, causing less trauma and permitting faster healing. A surgical drill may first be inserted through the guide sleeve for drilling the hole through the bone portions traversing the fracture. A surgical screw with enlarged head is then inserted into the guide sleeve to be threaded into the drilled hole, with the enlarged screw head temporarily and locally enlarging the guide sleeve as it passes therethrough until fully threaded into the drilled hole.

    摘要: A cannula (10) receives surgical instruments (120) for performing a surgical procedure on a body (130). The cannula (10) comprises a tube structure (12) defining a passage (16) through which the surgical instruments (120) are inserted into the body (130). The tube structure (12) has a proximal end (20) and a distal end (62). The tube structure (12) includes an expandable portion (40) for enabling an increase in the cross-sectional area of the passage (16) at the distal end (62). The expandable portion (40) of the tube structure (12), when expanded, has a conical configuration.

    摘要: Described herein are elongate device for modifying tissue having a plurality of flexibly connected rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element (e.g., chamber, bag, or the like) may be used to collect the cut or modified tissue. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.

    摘要: The invention relates to a resetting tool (1a), for the axial displacement of a Kirschner wire (2a), in particular, for application with bone plates, which may be implanted for the fixing of fractures. The above comprises a Kirschner wire (2a), comprising a thread in at least a part region and at least one guide tube (4a, 4b), by means of which the Kirschner wire may be positioned. A nut (3a) is provided, which is slotted and contains an internal drilling, such that the nut may be placed over the Kirschner wire and may be supported on the guide tube, whereby the Kirschner wire may be displaced in the axial direction by means of rotation of the nut.
