Abstract: Method and apparatus for skullcap and other bone cutting during autopsy. A power driven rotary cutter in the form of a circular blade saw is mounted on a carrier which moves around the skull of the cadaver and permits the cutter to move radially, toward and away from the axis of the skull. A follower which engages the skull controls the depth of cut so that only the skull bone is cut without damage to the brain tissue in the skull. The cutter is driven by a cable from a remote motor to minimize the weight of the cutter assembly on the carrier. The casing in which the cutter is mounted can be a handpiece of a cable driven tool. The cutter can also be used manually by removing the handpiece from the carrier. Power to the cutter is controlled so that the cutter cuts only bone and stops when soft tissue is engaged by the cutter, which avoids serious damage to soft tissue, and also avoids serious injury to the user if the blade slips.

Abstract translation: 尸检期间骷髅和其他骨切割的方法和装置。 圆锯片形式的动力旋转切割机安装在围绕尸体颅骨移动的支架上，并允许刀具径向，朝向和远离颅骨的轴线移动。 与颅骨接合的追随者控制切割的深度，使得只有颅骨被切割而不损害颅骨中的脑组织。 切割器由来自远程电机的电缆驱动，以最小化载体上的切割器组件的重量。 安装刀具的外壳可以是电缆驱动工具的手机。 也可以通过从托架上移除手机来手动使用切割器。 控制切割器的动力，使得切割器仅切割骨骼，并且当软组织被切割器接合时停止，这避免了对软组织的严重损坏，并且还避免了当刀片滑动时对使用者的严重伤害。
