4. Cleaning, Disinfection and Sterilization
The cleaning, disinfection and sterilization of handpiece, tip, and
wrench (include torque wrench and Endo wrench) are as follow.
Unless otherwise stated, they will be hereinafter referred to as
“products”.
Warnings
The use of strong detergent and disinfectant (alkaline pH>9 or acid
pH <5) will reduce the life span of products. And in such cases, the
manufacturer takes no responsibility.
Do not clean the handpiece with ultrasound cleaning machine.
This device shall not be exposed to high temperature above 138℃.
Processing limit
The products have been designed for a large number of sterilization
cycles. The materials used in manufacture were selected accordingly.
However with every renewed preparation for use, thermal and chemical
stresses will result in ageing of the products. The maximum number of
sterilizations for handpiece is 600 times. For tips, it is 300 times. And for
wrench, it is 1000 times.
4.1 Initial processing
4.1.1 Processing principles
It is only possible to carry out effective sterilization after the
completion of eective cleaning and disinfection. Please ensure that, as
part of your responsibility for the sterility of products during use, only
sufficiently validated equipment and product-specific procedures are
used for cleaning/disinfection and sterilization, and that the validated
parameters are adhered to during every cycle.
Please also observe the applicable legal requirements in your country
as well as the hygiene regulations of the hospital or clinic,especially with
regard to the additional requirements for the inactivation of prions.
4.1.2 Post-operative treatment
The post-operative treatment must be carried out immediately, no
later than 30 minutes after the completion of the operation. The steps are
as follows:
1. Let the Ultrasonic scaler works for 20-30 seconds under irrigation
mode to ush the handpiece and tip;
2. Remove the handpiece from the Ultrasonic scaler, and rinse away
the dirt on the surface of product with pure water (or distilled water/
deionized water);

9
3. Dry the product with a clean, soft cloth and place it in a clean tray.
Notes
a) The water used here must be pure water, distilled water or
deionized water.
4.2 Preparation before cleaning
Steps
Tools: Torque wrench, tray, soft brush, clean and dry soft cloth.
1. Remove the tip from product with torque wrench provided by
Guilin Woodpecker Medical Instrument Co., Ltd, and then put the tip and
wrench into a clean tray.
2. Unscrew the nipple of product counterclockwise, remove the
sealing ring, light pipe, and LED lamp(if any), and put them in the tray.
3. Use a clean soft brush to carefully brush the joints between product
and the connector of cable, front thread, horn, nipple, seal ring, light pipe
and LED lamp(if any) until the dirt on surface is not visible. Then use
soft cloth to dry the product and accessories and put them into a clean
tray. The cleaning agent can be pure water, distilled water or deionized
water.
Disassembling steps
4.3 Cleaning
The cleaning should be performed no later than 24 hours after the
operation.
The cleaning can be divided into automated cleaning and manual
cleaning. Automated cleaning is preferred if conditions permit.
4.3.1 Automated cleaning
•The cleaner is proved to be valid by CE certication in accordance

10
It is recommended to use a washer-disinfector in accordance with
EN ISO 15883. For the specic procedure, please refer to the automated
disinfection section in the next section “Disinfection”.
Notes
a) The cleaning agent does not have to be pure water. It can be
distilled water, deionized water or multi-enzyme. But please ensure that
the selected cleaning agent is compatible with the product.
b) In washing stage, the water temperature should not exceed 45 °C,
otherwise the protein will solidify and it would be dicult to remove.
c) After cleaning, the chemical residue should be less than 10mg / L.
4.4 Disinfection
Disinfection must be performed no later than 2 hours after the
cleaning phase. Automated disinfection is preferred if conditions permit.

it for twice with each rinse lasting for 1 minute. (c2) In the washing
stage, the water temperature should not exceed 45 °C, otherwise the
protein will solidify and it is dicult to remove. (c3) The solution used
can be pure water, distilled water, deionized water or multi-enzyme
solution, etc., and only freshly prepared solutions can be used. (c4)
During the use of cleaner, the concentration and time provided by
manufacturer shall be obeyed. The used cleaner is neodisher MediZym
