That is, the triangular pyramid is used as a bit of the drill, and the stem 2 is used as a connecting member and a rotary shaft between the hand grip and the drill blade 1. The characteristic of triangle high stability is utilized, three edges are used as grinding blades 11, and the target position is cut and ground perpendicular to the axis after the drill bit rotates, or the side blades of small parts of the tip are used for extending into the gap for processing.
Meanwhile, grooves 12 are formed in three side faces of the triangular pyramid, heat generated by friction is accelerated to be dissipated by increasing the contact area with air side, and the concave-convex surface can effectively prevent substances from being adsorbed on the side faces of the triangular pyramid, particularly when the drill blade part stretches into a gap, and the grooves can serve as channels for discharging liquid and bone fragments. The center of gravity of rotation can also be adjusted by the groove, so that the drill blade part rotates more stably, and more cutting force is concentrated at the grinding blade part.
