SECTION 1: GENERAL INTRODUCTION
RCTI-DY (II) Endo Motor is an endodontic operation instrument which
combined with both endo motor and apex locator function. Endo motor
function is a kind of endodontic micromotor to drive NiTi instruments,
which can assist the dentists to shape more standard root-canal in the
process of root-canal treatment based on the micro-electronic control
technology. Apex locator function is a kind of highly precise instrument
used for determining the position of apex of root canal
This unit contributes to alleviate the dentist’s working intensity.
Product application and intended use
RCTI-DY (II) Endo Motor is an endodontic operation instrument which
combined with both endo motor and apex locator function.
Endo motor is used for treat the root canal pulp necrosis, chronic pulpitis,
chronic apical periodontitis (including meat tooth apical swelling,
periapical abscess, periapical cyst), periodontal pulp syndrome and
systemic diseases should not be extract but urgent needed to be treat.
Apex locator function is used for determining the position of apex in the
root canal.
Unique advantages
Use Endo rotary file to machinery enlarge the root canal ，Not only
enlarges to the root canal in straight situation, but also works for curved
root canal. In combination with our Apex locator function, our equipment
can independently realize Endo motor function or Apex locator function,
but also it can realize both the mentioned two functions at the same time.
1, Large size LCD screen provide more clear and accurate data to the
operator during their operation.
2, 10 different program (Can be memorized) which can be preset
according the requirement of the operator.

3, This unit can adjust freely the torque value according to the required
Endo rotary file specification，the LCD displays the working trace of the
present torque, more clear and convenience during the operation of
dentists.
4, Auto-reverse function: When the rotary file reaches the preset torque,
the file will automatically withdraw until resistance cleared.
5, The operation handpiece is controlled by foot pedal.
6, The operation handpiece is designed as soft power on and power off,
which do not have sense of shock when start rotary the Endo file and also
avoid the break off of Endo file by speed up in short period.
7, The unit is powered by rechargeable Lithium battery, in order to protect
the life-span and working life of the battery. The machine will turn off
automatically in 8 minutes without use.
8, Contra angle, file holder and stainless hook can be 135℃autoclaved.
9, Build-in Rechargeable battery, greatly resolved the inconvenience of
frequently replace the battery and the cost of using our equipment.
10, The Apex locator function can preset the Apex area, when the rotary
file arrived to the preset Apex area, the machine will stop rotary.

program can be memorized and when restart the unit, you can just find
the preset program by press “Program” button in a convenience way.
3, Torque can be adjusted range from 0.6-5.2 N/cm, each level can be 0.1
N/cm increase or decrease.
4, After set the specification, long-press the SAVE button for confirm. If
didn’t press the SAVE button then the specification will not keep for next
time.
