Chapter 1 - Warnings, Precautions and Notes
Warnings and Precautions
• This equipment, in conjunction with the accessories, is intended to produce high-frequency
mechanical energy which enables hemostatic cutting and/or coagulation of soft tissue.
• Safe and effective ultrasonic surgery is dependent not only upon equipment design, but also, to a
large extent, upon factors under control of the operator. It is important that the instructions supplied
with this equipment be read, understood, and followed in order to enhance safety and effectiveness.
• The H
ARMONIC
™ Generator 300 System, including the hand piece, is not Magnetic Resonance safe
and is not Magnetic Resonance compatible.
• Equipment is not suitable for use in the presence of a flammable anesthetic mixture with air or with
oxygen or nitrous oxide. It is possible to create sparks by hitting other metal instruments. Sparks
may ignite flammable gases such as bowel gas.
• The H
ARMONIC
™ Generator 300 System must be operated within the required ambient operating
conditions. Refer to Chapter 14 – System Specifications.
• The H
ARMONIC
™ Generator 300 System should be tested on a periodic basis by qualified biomedical
maintenance personnel to ensure proper and safe operation.
• Refer all servicing to qualified biomedical personnel. Your Ethicon Endo-Surgery
representatives are available to assist in having your equipment serviced.
• Removing the top cover of the generator unit may expose the user to parts within the generator unit
which may have high surface temperatures and high voltage. These surfaces are potentially
dangerous and should be treated with extreme caution.
• Always unplug the generator from the wall outlet prior to opening the cover for servicing. This poses
a potential electric shock hazard.
• After removing the cover, inspect the internal components for obvious damage or foreign debris.
Never power ON a suspected problem unit.
• Never remove or install any parts with power on.
• To avoid user or patient injury in the event that accidental activation occurs, the The H
ARMONIC
™
Generator 300 System instrument blades should not be in contact with the patient, drapes, or
flammable materials while not in use. During prolonged activation in tissue, the instrument blade,
clamp arm and distal end of the shaft may become hot. Avoid unintended blade contact with tissue,
drapes, surgical gowns, or other unintended sites after activation.
• The user should verify that the power receptacle with which this unit is used is properly grounded
and is correctly polarized. Do not use ground cheater plugs or extension cords. Do not connect the
The H
ARMONIC
™ Generator 300 System to an ungrounded outlet. Grounding reliability can only be
achieved when this equipment is connected to a hospital-grade receptacle. (Refer to
Chapter 14 – System Specifications.)
• Verify that the outlet voltage correctly corresponds to the generator’s requirements. (Refer to
Chapter 14 – System Specifications.) Connection to an improper power supply may result in damage
to the generator and risk of shock or fire hazard.
