Claim 16:
17. A robot-assisted ultrasonic bone power system, including an ultrasonic bone power system and a robot-assisted surgery system, wherein the ultrasonic bone power system includes:
an ultrasonic transducer for converting electric energy into mechanical energy;
an ultrasonic bone scalpel for transferring the mechanical energy to a bone to be cut; and
the robot-assisted surgery system for assisting in a surgical operation,
wherein the ultrasonic bone scalpel has an ultrasonic bone scalpel bit including a scalpel bit end portion located at a distal end of the scalpel bit, the scalpel bit end portion being formed to have a flat shape and provided with a cutting portion, wherein
the cutting portion includes a distal end portion, a first side portion and a second side portion, the first side portion and the second side portion being symmetrically arranged relative to a longitudinal axis of the scalpel bit end portion in a width direction of the scalpel bit end portion, wherein the distance between the first side portion and the second side portion in a width direction of the scalpel bit end portion decreases or remains unchanged toward the distal end portion;
the cutting portion further includes a plurality of protrusions formed near the distal end portion, the plurality of protrusions projecting outwardly from the first side portion and the second side portion symmetrically relative to the longitudinal axis in the width direction of the scalpel bit end portion; and wherein the plurality of protrusions include a first protrusion and a second protrusion, the first protrusion is located at the junction of the distal end portion and the first side portion, and the second protrusion is located at the junction of the distal end portion and the second side portion; and wherein the maximum width of the first protrusion and the second protrusion in the width direction of the scalpel bit end portion is greater than the maximum distance between the first side portion and the second side portion in a width direction of the scalpel bit end portion; and
a recess which is recessed toward a proximal end of the scalpel bit end portion is formed on the distal end portion.
