Abstract: Disclosed are a method for determining a position of an ultrasonic osteotome (10), a system, and a computer-readable storage medium. The method includes: obtaining an acoustic impedance signal of the ultrasonic osteotome (10); and determining a current position of the ultrasonic osteotome (10) in bone tissue to be cut based on the acoustic impedance signal. In this way, an operator (50) can conveniently obtain the position of the ultrasonic osteotome (10) in real time, which can effectively prevent a movement path of the ultrasonic osteotome (10) from deviating from a target path, thereby reducing damage to soft tissue during surgery.

Abstract: The present application provides a medical ultrasonic scalpel, a medical ultrasonic scalpel system, and a robotic-assisted ultrasonic scalpel system, and relates to the technical field of medical instruments. In the medical ultrasonic scalpel, a composite vibration pattern generating portion is provided on at least one of a handle and a shank and can, under the action of a vibration source, drive a blade to generate a composite vibration including at least two of a longitudinal vibration, a torsional vibration and a bending vibration, such that the medical ultrasonic scalpel can generate a variety of vibrations to adapt to various types of surgeries, thereby improving the scope of application of the medical ultrasonic scalpel in surgery.

Abstract: An ultrasonic bone scalpel bit includes 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. 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. The cutting portion further includes a plurality of protrusions formed near the distal end portion, the plurality of protrusions projecting outward 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.

Abstract: Disclosed is an ultrasonic surgical system, comprising: an ultrasonic transducer used for converting an alternating current signal into vibration; and an ultrasonic amplitude transformer used for amplifying the amplitude of the vibration generated by the ultrasonic transducer, wherein the product L1×C1 of a dynamic equivalent inductance L1 and a dynamic equivalent capacitance C1 of the ultrasonic surgical system in a no-load state and the product L?×C? of a dynamic equivalent inductance L? and a dynamic equivalent capacitance C? of the ultrasonic surgical system in an on-load state satisfy the relational expression ? 1 - L 1 × C 1 L ? × C ? ? = ? , such that a resonance frequency fs of the ultrasonic surgical system in the no-load state and a resonance frequency fs? thereof in the on-load state satisfy the relational expression ? 1 - f s ? f s ? = ? , wherein a is less than or equal to 0.1%, and preferably ? is less than or equal to 0.05%.
