摘要： A self-drilling, self-tapping screw for use in repairing broken bones. The screw is made of a high strength material selected from the group consisting of titanium alloys, chrome cobalt, and high strength resinous polymer. The screw has threw segments: a tip region, a body region and a head region. The tip and body regions have a retention thread formed over substantially their entire lengths. The tip has an included angle .alpha. in the range between 45.degree. and 50.degree.. The head region is specifically designed to maximize the torque it can withstand and minimize the amount of material removed in formation of the recess. The head has a generally frusto-conical shape with an included angle of between 90.degree. and 120.degree. to prevent pull through while minimizing the head's profile. The retention threads on the tip region and the body region have similar shapes and pitches with the pitch on the tip region being slightly smaller than the pitch on the body region. Each of the retention threads has a lead angle between 48.degree. and 52.degree., and a trailing angle between 98.degree. and 102.degree., as measured from the centerline of the screw.
摘要翻译： 用于修复破骨的自钻自攻螺钉。 螺杆由选自钛合金，铬钴和高强度树脂聚合物的高强度材料制成。 螺钉已经投掷段：尖端区域，身体区域和头部区域。 尖端和身体区域具有在其基本上整个长度上形成的保持螺纹。 尖端的夹角α在45°和50°之间的范围内。 头部区域被专门设计成使其可以承受的扭矩最大化并且最小化在凹部形成中移除的材料的量。 头部具有大致截头圆锥形形状，夹角在90°和120°之间，以防止拉动，同时使头部轮廓最小化。 尖端区域和身体区域上的保持螺纹具有相似的形状和间距，尖端区域上的间距略小于身体区域上的间距。 每个保持螺纹具有从48°至52°之间的导程角，以及从螺钉的中心线测量的98°至102°之间的后角。
