Dentsply Professional Inc. MW874200 사용자 설명서

The eStylus™ system is an electric motor driven
handpiece with various attachments intended for 
cutting, shaping, filing, drilling, cleaning and polishing
procedures in general and endodontic dentistry.

Do not use this electric motor system within the oral
cavity when a soft tissue wound is present. Air exiting
from the attachment and motor could enter a wound,
leading to air embolism or infection.

The eStylus motor hose is not sterilizable, and other
than as described in these instructions the eStylus
motor is not sterilizable. The eStylus system does not
have provision for delivery of sterile water. Therefore,
the eStylus system is not recommended for use in 
procedures that require a sterilized motor and hose
and/or a sterile water supply. The eStylus system
should not be installed in a sterile field.

ISO 11498 states "Dental low voltage electric motors
shall not be used in the presence of a flammable
anesthetic gas mixed with air, oxygen, or nitrous
oxide." (Note: nitrous oxide by itself is not a 
flammable anesthetic gas.) 

• This product is intended for use by dental 

professionals only.

• Before operating the eStylus Electric Motor System,

carefully read and follow these instructions and
save them for future reference. Observe all cautions
and warnings.

• Attachments should be steam-sterilized between

patients to prevent cross-contamination which could
result in serious illness or even death from infec-
tious organisms such as HIV (the virus that causes
AIDS) or hepatitis B. NOTE: Sterilize Before
Use. Supplied Non-Sterile.

• Do not cut with the handpiece attachments unless

you are sure the bur is secure.

• Do not extend burs outward from handpiece attach-

ment head.

• Burs must be inserted all the way into chuck for

proper bur retention.

• Extended burs could result in personal injury due to

bur ejection, bent burs, or inadequate cooling.

• Never mount an attachment on a motor while it 

is running.

• Never press a gear ratio button, or the controller or

remote control, while the handpiece is running.

• The endodontic "torque limit" feature is intended 

as an aid to help you reduce breakage of rotary 
NiTi endodontic files. It is not a substitute for your
professional judgment and good clinical practice,
such as:

•

selection of clinically appropriate files

•

selection of rotary speed and torque limit 

appropriate to each file and clinical procedure

•

establishing appropriate access and guide path

•

appropriate file advancement rate

•

proper use of lubricant and cleaning fluids

•

periodic cleaning of the file 

•

examination of files for defects or wear

•

not using files beyond their recommended life

•

your tactile "feel" of the resistance that the

file encounters.

•  In order for your eStylus system to properly control 

speed and torque, it is essential that you set the 
gear ratio that corresponds to the attachment you 
are using. See the sections of this guide which 
describe how to select one of the pre-set gear 
ratios or enter a custom gear ratio in your eStylus 
controller.

• The eStylus motor normally provides chip-air and 

water to the attachment. If you are performing 
endodontic or other procedure for which chip-air 
and water spray may not be clinically appropriate,
you should turn off chip-air and water at your 
dental unit or use an attachment that does not 
have chip-air and water spray (i.e. Midwest 10:1).
