WARNING:
Please refer to the instructions for use provided with the electrosurgical
unit. Electrosurgical systems may be of the oating 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 ammable gas being present within a body
cavity, use nonammable gas (such as CO
2
or air) instead.
• When using nonammable gas, there is a possibility of gas embolism
if excessive gas is ushed. When using nonammable gas, be careful
not to ush 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.
Nonammable gas from a pressure-regulated and ow-rate controlled source can
