Surgical instruments with ultrasonic cutting and sensing capabilities, as well as related systems and methods, are disclosed herein. In one aspect, the present disclosure provides a surgical instrument including a housing; an ultrasonic transducer contained in the housing and capable of acting as an ultrasonic receiver; an output member at least partially received in the housing and configured to be driven by the ultrasonic transducer; a dissection head having an attachment portion configured to be selectively driven by the ultrasonic transducer; and a controller operable to initiate and stop the ultrasonic transducer according to an alternating duty cycle.

Ultrasonic bone cutting device with integrated sensing

A surgical instrument employs a mass-spring system to drive the periodic reversal of the rotational direction of a bone dissection head. The instrument comprises a housing, a harmonic oscillator contained in the housing, an output member at least partially received in the housing and configured to be driven by the harmonic oscillator to reversibly rotate about a longitudinal axis in alternating directions, a dissection head having an attachment portion configured to be selectively driven in alternating rotational directions by the output member to remove material from a target bone, and a controller operable to initiate and stop the harmonic oscillator.

Non-rotational bone cutting tools and related systems and methods

A surgical system which may include a controller, a data entry device, a powered surgical handpiece and a surgical tool adapted to couple to the surgical handpiece. The surgical handpiece can include motor direction control and feedback, safety stop features, stimulation and nerve integrity monitoring, a tool connector assembly configured to retain a variety of surgical tools and optional navigation and/or electric ratcheting features.

Surgical system including powered rotary-type handpiece

A motor for a surgical instrument includes a rotor and a stator. The rotor includes a shaft and a magnet. The stator includes (i) a cavity in which the rotor is disposed, and (ii) a coil assembly. The coil assembly includes multiple phase sets. The phase sets include multiple sets of wires. Each of the phase sets includes multiple coils and corresponds to a respective one of the sets of wires. The coils in each of the phase sets are at respective positions about the rotor. One of the sets of wires includes at least three wires. The stator causes the rotor to axially rotate a surgical tool of the surgical instrument based on current received at the sets of wires.

Surgical instrument motor with increased number of wires per phase set and increased fill factor and corresponding manufacturing method

A powered surgical handpiece including a housing, a printed circuit board, a sensor, and an actuator assembly. The housing has a longitudinal axis extending from a first end to a second end of the housing. The printed circuit board has a first face and a second opposing face. The first and second faces extend perpendicular to the longitudinal axis. The sensor is coupled to the first face of the printed circuit board. The sensor is centered along the longitudinal axis of the housing. The actuator assembly includes a lever and an actuator. The lever is pivotally coupled to the housing. The lever maintains a magnet slidably positionable along the lever. The magnet is positionable to be proximal to the sensors.
