    • A surgical dissection tool for cutting bone and other tissue includes a cutting head having an outer surface having non-paired or an odd number of flutes formed therein. Each flute includes a rake surface intersecting with the outer surface to form a cutting edge, and a relief surface opposite the rake surface. The relief surface and the rake surface form a first angle. Each flute also includes a leading angled surface extending from the relief surface to a distal end portion of the cutting head, the leading angled surface and the rake surface forming a second angle substantially the same as the first angle.
    • 用于切割骨骼和其他组织的手术解剖工具包括具有在其中形成有非配对或奇数数量的凹槽的外表面的切割头。 每个凹槽包括与外表面相交的前刀面以形成切削刃,以及与前刀面相对的浮雕表面。 浮雕表面和前刀面形成第一角度。 每个凹槽还包括从凸起表面延伸到切割头的远端部分的前倾角表面,前倾角表面和前刀面形成与第一角度基本相同的第二角度。
