3-6. Electrosurgery (Except EG-1690K)
WARNING:
Please refer to the instructions for use provided with the electrosurgical
unit. Electrosurgical systems may be of the floating type (Type BF, Type
CF) or non-floating (Type B). To avoid patient and user burn, use only
the floating type electrosurgical systems. Do not use the non-floating
(Type B) electrosurgical systems. The electrosurgical generator and any
electrosurgical accessory should be carefully and thoroughly inspected.
Only the user can determine if the condition of the electrosurgical
generator and the electrosurgical accessory are suitable.
WARNING:
•
Using electrosurgical devices in a flammable atmosphere, such as an
environment with a high oxygen concentration, may cause explosion.
If there is a possibility of flammable gas being present within a body
cavity, use nonflammable gas (such as CO
2
or air) instead.
•
When using nonflammable gas, there is a possibility of gas embolism
if excessive gas is flushed. When using nonflammable gas, be careful
not to flush excessive gas. Use suction capability of an endoscope to
remove gas if necessary.
CAUTION:
NEVER use any electrosurgical devices with the EG-1690K. It may cause to
burn a peripheral mucosal except the target areas.
1) The user has the option of using a nonflammable gas for insufflation.
Nonflammable gas from a pressure-regulated and flow-rate controlled source can
be connected to the provided or optionally available gas adapter, model OF-G11,
as described for Laser in section 3-5.
