摘要： A bone fixation device such as a screw, pin, staple, cable or anchor has a microtextured contact surface to enhance installation or gripping characteristics, preferably by providing directional or anisotropic engagement. A surface texture comprised of patterned microfeatures imparts a roughness or actual mechanical engagement that prevents loosening. In different embodiments the features resemble an array of microbumps or pyramids, or anisotropic features such as rasp teeth, shingles, or slanted cantilevered fiber/rods. The use of microbumps present a smaller surface area when moving, while providing full area contact after the surfaces have relaxed or decompressed; installation may be effected with low force, while high static or resting friction prevents disengagement. Features with directional asymmetry or angled suspension allow the textured surface to slide or deflect when the fixation device moves in one direction, while presenting a high resistance to torque or linear motion when moved in the other direction. Manufacturing is achieved with ion beams or directional treatment with energetic radiation, and regular arrays of the microfeatures may be produced as stationary surface growth phenomena without the use of pattern masks or mechanical contact. One manufacturing apparatus rotates the fixation device about a longitudinal axis while it is irradiated along an oblique axis. A bone pin may have centrally-directed spurs that allow a multi-segment fracture to be securely pinned without threading. An elastic fastener body such as a screw or pin can be pre-tensioned to place the bone under a torsional or compressive load, or introduce strain at the healing site.

摘要： A bone plug for intramedullary insertion into the canal of a bone to restrict the bypass of cement during implant surgery is described. The bone plug is made of a bioabsorbable material and has a tapered central body providing the primary support for the plug. A plurality of radially extending disc-like fins extend from the body at spaced locations. The taper provides the distal fin with a greater degree of flexibility due to the long cantilever, thus permitting an ease of insertion into the intramedullary canal while the larger diameter body and shorter proximal fins lend structural stiffness to resist the migration of the device.

摘要： A self-centering bone drill comprises a drill bit having a proximal end and a distal end, a cutting surface at the distal end, and a first radially extending flange. A tubular housing coaxially receives the drill bit and a spring is coaxially received within the housing, and coaxially receives the drill bit. The spring is compressed between the first radially extending flange and an interior abutment surface on the housing distal of the first radially extending flange to urge the housing distally along the drill bit. A chamfered surface on a distal end of the housing engages a chamfered surface on a work piece to center the drill bit.

摘要： A guard device with angled cranium guide that can be removably and replaceably attached to an existing craniotome for producing a stable bone flap system includes an elongate stem defining a longitudinal axis between a proximal end and distal end. The proximal end is adapted for attachment to the craniotome. A footplate extends from the distal end of the stem at an angle with respect to the longitudinal axis of the stem. The footplate is positioned adjacent to the cutting portion of the craniotome and prevents the cutting portion from penetrating too far into the skull. On one side of the stem between the proximal and distal ends is an angled cranium guide. The dura guard with its angled cranium guide enables the surgeon to rest the guide agains the cranium and the maintain the craniotome at a fixed angle to cut a bone flap at an angle.

摘要翻译：诸如螺钉，销，钉，电缆或锚的骨固定装置具有微观结构的接触表面，以优选地通过提供定向或各向异性接合来增强安装或夹持特性。由图案化微特征组成的表面纹理赋予粗糙度或实际机械接合以防止松动。在不同的实施例中，特征类似于微丸或金字塔的阵列，或各向异性特征，例如锉齿，带状疱状物或倾斜悬臂的纤维/杆。使用微丸在移动时呈现较小的表面积，同时在表面松弛或减压后提供全面接触; 可以以较低的力进行安装，而高静态或静止的摩擦阻止脱开。具有方向不对称或倾斜悬挂的特征允许纹理表面在固定装置沿一个方向移动时滑动或偏转，同时当向另一个方向移动时具有高的扭矩或线性运动阻力。使用离子束或用能量辐射进行定向处理来实现制造，并且可以在不使用图案掩模或机械接触的情况下，产生微特征的规则阵列作为固定表面生长现象。一个制造装置在沿着倾斜轴线照射时围绕纵向轴线旋转固定装置。骨针可以具有中心定向的刺，其允许多段骨折被牢固地固定而不穿线。可以预先拉紧诸如螺钉或销的弹性紧固件体，以将骨放置在扭转或压缩载荷下，或在愈合部位引入应变。
