WARNING: Incompatible Accessory Hazard.
The output receptacles of the gi4000
ESU are designed to accept a single type of electrosurgical instrument at a time.
Reference the Instructions for Use provided by the instrument manufacturer for proper
connection and use of the instrument with the electrosurgical system.
WARNING: Personal Injury or Equipment Damage Hazard.
Use the gi4000 ESU
ONLY
if the Power ON Self-Test (POST) has been successful, otherwise inaccurate
power outputs may result in serious patient or user injury or damage to equipment.
→
If the display fails, the gi4000 ESU can no longer be operated safely. If the
touchscreen is non-responsive or no longer visible, immediately stop using
the equipment and contact
STERIS Customer Service at 1-800-769-8226
or your local STERIS Endoscopy Electrosurgery Specialist for a repair or
replacement.
WARNING: Electrical Shock Hazard.
Electrosurgical accessories should only be
connected to the gi4000 ESU when output energy is
OFF
. Failure to turn energy off may
result in electrical shock the patient and / or user. When connecting accessories, it is
recommended the system be placed in STANDBY MODE.
WARNING: Alternate Site Burn and / or Shock Hazard
.
DO NOT
place active portions
of accessories
in contact with grounded patients as a burn may result if the unit is
inadvertently activated when not in Standby Mode.
→
DO NOT
activate the gi4000 ESU in open circuit conditions.
→
Activate
ONLY
when the active accessory is in view and near or touching
target tissue.
→
DO NOT
use worn or ill-fitting active cords, dispersive electrode cables or
connector adapters as shock or burn can occur.
→
DO NOT
leave the active accessory in the patient when not in use.
WARNING: Burn Hazard.
The user should assess the condition of the patient and use
clinical judgement to set the appropriate electrosurgical settings to avoid patient injury.
Use the lowest output setting necessary to achieve desired clinical effect.
→
The higher the electrical output power that is applied, the greater the
hazards posed by electrosurgery. Always use the lowest power setting that
achieves the desired surgical effect.
→
Certain devices or accessories may present an unacceptable risk at low
power settings. For example, when using argon beam coagulation, the risk
of gas embolism rises if there is insufficient RF power to produce a rapid,
impermeable eschar on the target tissue.
→
The temperature at the patient dispersive electrode application site may
increase during long, continuous activations. Ensure there is sufficient
cooling phases between activations to prevent temperature build-up at the
dispersive electrode.
WARNING: Neuromuscular Stimulation Hazard.
The use of modes that produce an
electrical arc between the active accessory and patient tissue may result in
neuromuscular stimulation.
Use the lowest output setting necessary to achieve desired
clinical effect.
