CAUTION

IMPORTANT

Non-Controlled Document

The Olympus Electrosurgical Unit PSD-10 has been designed for endoscopic electrosurgery (coagulation,

polypectomy, sphincterotomy, etc.) in conjunction with Olympus fiberscopes that are applicable to electrosurgery, Olympus electrosurgical accessories and light sources. Do not use the equipment for any purpose other than its intended use.

Please read this entire manual carefully before using the equipment in order to acquaint yourself

with the proper care and handling of your new electrosurgical unit. Then prepare and inspect the

equipment following these instructions.

Safety precautions must be exercised when handling electrical equipment to prevent operator/ patient shock, fire hazard and equipment damage.

If you have any questions concerning the material contained in this manual or concerning the operation or safety of the equipment, please contact your Olympus representative or the nearest

Olympus Service Center.

FEATURES AND MAIN SPECIFICATIONS

1-1 Features

1. Simplified pre-procedural test, using a Check Lead, of the power output of the PSD-10 alone as well as that of the entire electrosurgical system including the endoscope and endoscopic electrodes. Test results confirmed by TEST “OK” or “FAULT” indicator lights on the front panel.

2. Push-button selection of CUT, COAG or BLEND current. Output power is controlled by a single-pedal footswitch.

3. The connection monitor circuit detects loose or inadvertent misconnection of cords or broken wires in the S-P cord (Safety cord and Patient cord).

If any irregularity is present, the monitor activates an alarm and inhibits output (current is not delivered when the footswitch is depressed) to ensure safety of the procedure.

4. The feedback ratio monitor scans the entire circuit when the footswitch is depressed. If excessive leakage current is present, the output is inhibited to ensure safety of the procedure.

5. Flat switches and display panel can be easily wiped clean.

6. Compact, lightweight and portable.

1-3 Safety Precautions

Non-Controlled Document

The PSD-10 should be used only in a medical facility under the supervision of a

trained physician.

The PSD-10 is designed (floating) to function integrally with insulated patient attachments

(active electrode and patient plate) to prevent operator/patient shock. To prevent shocks which may be caused by leakage current from other apparatus applied to the patient, endoscopes and cameras used with the PSD-10 should not be grounded.

The endoscopist and his assistant should wear rubber handgloves as an added precaution.

When using a camera (except the SC16-10) an insulating hood should be attached

to the camera’s eyepiece.

The enclosure of the PSD-10 must be grounded securely and effectively. Do not

defeat the line cord ground connection.

The PSD-10 should never be applied to the heart directly.

Never install and operate the PSD-10 where there is a risk of flammable gases.

Should any irregularity or abnormality be suspected during operation, immediately

stop the use of instrument and turn OFF the power switch.

Keep liquids away from all electrical equipment to prevent operator shock and instrument

damage. Do not use the PSD-10 if spilled fluids have entered the unit.

Please investigate the possibility of electronic interference for other electromedical

equipment in conjunction with the PSD-10 prior to use.

Do not install the patient plate adjacently to an artificial bone (metal), etc.

Keep adequately away from cords of electric scalpel (scalpel holder, scalpel cord and

Non-Controlled Document

patient plate cord), scalpel main body and cords, main body of other electromedical equipment.

Do not loop cords of electric scalpel (scalpel holder, scalpel cord and patient plate cord). Do not contact these cords with the patient or metallic portion of an operating table, etc.

The PSD-10 should not be used in conjunction with electrical apparatus whose safety

against leakage current is not guaranteed.

Radio-frequency and spark discharge “noise” may adversely affect other electro-medical

equipment being used in the proximity.

Do not apply the electric scalpel to the patient who has a pacemaker in his body.

The use of a radio-frequency noise filter in monitor electrode lines may reduce interference.

Patient monitor electrodes must be placed as far away as possible from the operative

field.

Needle type electrodes should not be used as they increase the risk of burns.

To prevent instrument damage, the active electrode and the patient plate should not

be short-circuited. Do not activate the electrode for an extended time when it is not touching the target

tissue.

The PSD-10 should be used in accordance with the operating environment specified in 1 – 2 Main Specifications; otherwise improper performance, compromised safety or instrument damage may result.

Repairs should be carried out only by an Olympus Service Center.
