Chapter 5 How to Use
WARNING
Prior to performing endoscopic electrosurgery, one should have a thorough understanding
of the manufacturers' instructions for all equipment involved and one should be familiar with
the specific safety and usage aspects of each endotherapy device.
CAUTION
Prevent patient's body from touching electric conductor such as metal part of bed while
performing high-frequency treatment. It could cause thermal injury to a patient due to
energization via the conductive part.
When performing high-frequency treatment, take care that patient's vomitus or body fluids
do not make contact with the conductive parts such as a metal part of the bed. It could
cause thermal injury to a patient due to energization via vomitus or body fluids.
While performing high-frequency treatment, ensure that the end-user does not touch the
patient. It could cause thermal injury to a patient and/or end-user.
Operate the electrosurgical unit within specified output range as per instructions provided
in the operation manual of the electrosurgical unit. Leakage current may cause thermal
injury.
Do not energize the electrosurgical unit when the high-frequency endotherapy device or
electrically active portion is in contact with the distal end of endoscope. Thermal injury to a
patient or endoscope failure may occur.
Do not apply the current under the circumstance that patient's clothing is wet when
performing high-frequency treatment. Doing so may cause thermal injury.
(1) Prepare, inspect and connect the electrosurgical unit and high-frequency endotherapy device
as per instructions provided in respective manuals.
(2) Perform high-frequency treatment as per instructions provided in the manual of the
electrosurgical unit and high-frequency endotherapy device.
