Abstract
A bone-excavating apparatus comprises a shaft and a drill so sized as to be inserted into an articulation through a skin-cutting portion and removable from the shaft. In a state in which the shaft is installed on the drill, the shaft and the drill have a drill-locking mechanism for preventing the drill from being moved to a base side of the shaft and a torque transmission mechanism for transmitting, to the drill, a rotational force applied to the shaft in a direction in which a bone-excavating blade is allowed to excavate the bone.
