Notes on reprocessing of resterilizable
products
Products
Reusable products supplied by Leica Microsystems (Schweiz)
AG such as rotary knobs, objective protective glasses and
capping pieces.
Reprocessing restrictions:
With regard to the processing of medical products used on
patients or suspected patients suffering from Creutzfeldt-Jacob
disease (CJD) or its variant (vCJD), the local legal regulations
must be observed. As a rule, resterilizable products used for
these patients can be eliminated without danger by burning.
Occupational safety and health protection
Particular attention must be paid to the occupational safety and
health protection of the persons responsible for preparing
contaminated products. Current regulations of hospital hygiene
and prevention of infection must be observed in the
preparation, cleaning and disinfection of the products.
Limitation of reprocessing
Frequent reprocessing has little effects on these products.
The end of the product life cycle is usually determined by wear
and year and damage through use.
Instructions
Workplace
Remove surface contamination with a disposable cloth / paper
cloth.
Storage and transport
No special requirements.
It is recommended to perform the reprocessing of a product
immediately following its use.
Preparation for cleaning
Remove the product from the surgical microscope.
Cleaning: manual
Equipment: running water, rinsing agent, spirit, micro-fiber cloth
Procedure:
• Rinse surface contamination off of the product (temp. <40 °C).
Use some rinsing agent depending upon degree of
contamination.
• If the optics is heavily contaminated, e.g. finger marks,
fat streaks, etc., use spirit for cleaning.
• Dry off products, except for optical components, with a
disposable cloth/paper cloth. Dry off optical surfaces with a
micro-fiber cloth.

Address of local agent
Leica Microsystems (Schweiz) AG verified that the aforemen -
tioned instructions for the preparation of a product are suitable
for its reuse. The processing person is responsible for repro -
cessing with the equipment, materials and personnel and for
achieving the desired results in the reprocessing installation.
In general, this requires validations and routine monitoring of
the process. Every deviation from the supplied instructions
should also be examined carefully by the processing person to
determine effectiveness and possible detrimental
consequences.
