System Components

Generator 300

The generator supplies the hand piece with electrical energy and facilitates selection of power levels, system
monitoring, and system diagnostics.
Power is delivered by activating the foot switch or hand switch.

Hand Piece

The hand piece contains an acoustic transducer that converts the electrical energy supplied by the generator
to mechanical motion. The transducer is connected to an amplifier which amplifies the motion produced by
the transducer and relays it to the instrument.

Instrument

The mechanical motion from the hand piece advances to the instrument, transmitting ultrasonic energy which
enables hemostatic cutting and/or coagulation of tissue.
Note: Throughout this manual "instrument(s)" refers to U
coagulators, or coagulating shears.

Power Levels

The generator delivers two power levels: minimum (MIN) and maximum (MAX). The minimum power
level may be adjusted by the user from Level 1 to 5. The maximum power level is always Level 5. With all
instruments except the ball coagulator, use a higher generator power level for greater tissue cutting speed and
a lower generator power level for greater coagulation. For the ball coagulator, higher generator power levels
will provide greater coagulation. The amount of energy delivered to the tissue and resultant tissue effects are
a function of many factors including the power level selected, instrument characteristics, grip force (when
applicable), tissue tension, tissue type, pathology, and surgical technique.
Note: Refer to the instruments' package inserts for additional power level information, including
recommended starting power levels.
