摘要： A surgical cutting instrument (10) includes an outer tubular member (13), or cannula, sized for percutaneous insertion into an anatomical space. The outer tubular member has a cutting opening (14) at its blunt-tipped distal end (15). The proximal end is supported by a hand piece (11). A cutting member (20) includes a tubular member having a cutting head (43) portion at its distal end and a body portion (44) extending therefrom to the hand piece (11). A hinge (41) is integrally formed in the tubular cannula to connect the cutting head (43) portion with the body portion (44), to permit pivoting of the cutting head portion (43) relative to the body portion. As the cutting member (20) is reciprocated within the outer cannula (13), the cutting edge (22) contacts tissue drawn into the cutting opening (14). Resistance from the tissue causes the cutting head to pivot about the hinge to form an essentially zero clearance between the cutting head and the cutting opening in the outer cannula.

摘要： A curved needle (12) with a flexible leader wire (14) and a multi-stranded cable (17) fastened to the leader wire is passed through the sternum and around a vertically split in the sternum. A crimp (18) on the trailing end of the cable abuts one side of a stop bar (19) in front of the sternum. The needle and other end of the cable are passed from the other side of the bar through an aperture (21) in the bar and then separated from the leader. This procedure is repeated at the desired number of vertically spaced sites on the sternum to bring the sternum halves together under tension. A crimp (34) is swaged onto the cable at the other side of the bar whereby the crimp holds the cable in tension.

The body (11) includes two opposite faces (12, 14) and an outer surface (13) between the two faces (12, 14). The body (11) includes a porous biocompatible material for permitting tissue ingrowth therethrough. A sleeve (15) is disposed around the outer surface (13) of the body (11). The sleeve (15) is composed of a second material which is relatively stronger under compressive loads than the biocompatible material of the body (11). Also provided is a plurality of apertures (16) through the sleeve (15) in communication with the outer surface (13) of the body (11) for bone ingrowth. Means for attaching the sleeve to the endplates of adjoining vertebral bodies are also provided.
摘要翻译：脊柱植入物（10）的一个实施例包括主体（11），其尺寸和构造用于在相邻椎骨V之间接合。主体（11）包括两个相对面（12,14）和两个面之间的外表面（13）（12,14）。主体（11）包括用于允许组织向内生长的多孔生物相容性材料。套筒（15）围绕主体（11）的外表面（13）设置。套筒（15）由在主体（11）的生物相容性材料的压缩载荷下相对较强的第二材料构成。还提供了通过与主体（11）的外表面（13）连通的用于骨向内生长的多个通过套筒（15）的孔（16）。还提供了用于将套筒附接到相邻椎体的终板的装置。
