Limitations on reprocessing Repeated processing has a minimal effect on these instruments. The instru-ments have been validated for 25 cycles of reprocessing as instructed in this guide. End-of-life is normally determined by visible manifestation of wear and damage. See “Inspection and function testing” on page 10. CAUTION Do not use metal brushes or steel wool for cleaning.

The sterilisation department or reprocessing centre at your hospital or clinic is responsible for surgical instrument sterility. They should: • • •

Use device and product-specific validated procedures for cleaning, disinfecting and sterilisation. Use washer-disinfectors and sterilisers that are maintained and checked regularly. Make sure recommended parameters are applied for each cycle.

Instrument material compatibility • •

Cochlear has validated the instructions in this guide for preparing a surgical instrument for re-use. Staff at the hospital or the clinic are responsible for ensuring that reprocessing achieves the desired result-as performed using equipment, materials and staff in the reprocessing centre or sterilisation department. This requires validation and routine monitoring of the process. Any deviation from the instructions provided should be properly evaluated for effectiveness and potential adverse consequences.

Surgical Instruments Sterilisation Reprocessing Guide

•

To avoid corrosion, do not process Cochlear metal instruments with instruments that have aluminium, brass, copper or chrome-plated parts. Do not use cleaning detergents with the following ingredients: - Organic, mineral, and oxidising acid. The minimum allowed pH-value is 5.5. - Halogens (for example chlorine, iodine, bromine). - Aromatic, halogenated hydrocarbons. Do not expose instruments to temperatures higher than 142 °C (288 °F).

Reprocessing instructions

Preparation for cleaning Rinse under water at a temperature that should not exceed 45 °C (113 °F) while brushing for a minimum of 1 minute. CAUTION Do not use metal brushes or steel wool. For manual removal of impurities, use a soft brush only. For holes, use suitable interdental brushes.

The following reprocessing instructions are for instruments used with patients who in the general population represent no identified risk of Transmissible Spongiform Encephalopathies (TSEs) transmission and where: a. The instruments have not been exposed to tissue that are known to have highinfectivity for Creutzfeldt-Jakob disease (CJD) (e.g. dura)

Bone bed indicator 17 mm • •

The Bone bed indicator 17 mm consists of a body and a pin Disassembling required if assembled

b. Where the instruments have been exposed to tissue known to have high-infectivity for CJD (e.g. dura).

WARNING • The reprocessing should be performed by suitably trained staff using wellmaintained equipment in a facility that meets the requirements of ISO 17665- 1, for equipment validation and routine control. • For instruments used with patients who represent a definite or potential risk of TSE transmission, contaminated instruments should be placed immediately into the correct clinical waste container for disposal. Follow the legal provisions for your country and the hygiene instructions of your hospital or clinic.

Point of use Throughout the surgical procedure, wipe blood and debris from instruments to prevent drying. Do not allow contaminated devices to dry before reprocessing. Directly after use, remove coarse impurities from the instruments by wiping the articles using lint-free cloths dampened with distilled water and soak in distilled water until they are reprocessed. Instruments should be reprocessed within one hour after use.

Containment and transportation Follow the validated containment and transportation instructions of your hospital or clinic.

Automated cleaning Critical cleaning parameters were determined by rigorous automated cleaning methods developed using spore logarithmic reduction, total protein, haemoglobin and visual inspection criteria. For device contamination, a blood soil containing 2M calcium chloride (for coagulation purposes) and bone meal (1 g/100 mL of test soil) was inoculated with a minimum population of 104 CFU/mL of G. stearothermophilus and E. faecium. The instruments were exposed to the test soil for a minimum of 15 minutes and allowed to dry for a minimum of 1 hour before cleaning and disinfecting. Any pre-cleaning involved rinsing the instrument under water (49 °C; 120.6 °F) while brushing with a Spectrum M-16 brush for a minimum of 1 minute. After cleaning, test samples were visually inspected for any sign of remaining blood soil. Bioburden extractions were used to determine the number of spores, total protein and haemoglobin remaining on test samples. Comparison of data to positive controls and test protocol requirements determined if acceptance criteria were met.
