UES-40
Product Specification 1-2 ISSUE4
1. Outline
The ELECTROSURGICAL UNIT UES-40 (UES-40) is designed for use in medical facilities
under doctor supervision in combination with designated reusable high-frequency instru-
ments, endoscopes, and light sources in surgical procedures and treatment using endo-
scopes (fiber scopes, videoscopes, and rigid scopes) for the cutting and coagulation of living
tissue.
(1) Expanding the functions available with the UES-30
The UES-40 also offers an output system for use in physiological saline (TURis). TURis
frees surgeons from the need for a patient plate, and offers improved safety over con-
ventional TUR is.
TURis (TUR in saline): A technique for cutting and ablation in physiological saline
TUR: Transurethral resection of the prostate
(2) Supports the use of multiple electrodes
(Separate settings can be used for each system: bipolar, monopolar, and saline.)
(3) The UES-40 features exclusive specifications and is compatible with EndoALPHA.
(4) For easier use, the front panel is designed at a 20° vertical orientation.
(5) The design of the UES-40 is coordinated with the VISERA Video System.

3. Operating Requirements
(1) The operating conditions must be as follows.
Ambient temperature: 10°C to 40°C
Relative humidity: 30% to 85%
Atmospheric pressure: 700 hPa to 1060 hPa
Never use the UES-40 where flammable vapors occur.
(2) The power requirements are as follows.
(3) Do not use in combination with products not designated by Olympus.
(4) Before using the UES-40 for the treatment of patients wearing pacemakers, consult the
pacemaker manufacturer.
(5) Do not attach the patient plate for use near metallic implants.
(6) Do not wind UES-40 cords into loops or allow them to touch the patient or metallic parts
of the surgical table.
(7) Do not bundle UES-40 cords with cords of other medical equipment during use.
(8) Keep the UES-40 and its cords adequately separated from other medical equipment
and cords.
(9) If non-CF products are used in combination with the UES-40, do not use directly on the
heart.
(10) To ensure electrical safety, use of the following electronic medical equipment in combi-
nation with the UES-40 is prohibited:
a) Equipment not yet proven safe when used with the UES-40
b) Equipment not yet proven safe due to certain aspects of operation (such as the
leakage current)
(11) If the UES-40 is used in combination with endoscopic instruments for which the rated
voltage is listed in each instrument user manual, compare the open output-voltage char-
acteristics of the instruments with those of the UES-40 and adjust the output within the
USE-40’s rated voltage values. Refer to Fig. 1-1 to 1-4 for the open voltage characteris-
tics. If the user’s manuals for these instruments do not list the rated voltage, set the out-
put low initially and then gradually increase the output level.
