Contraindications

4.2

Side effects

The objective lens serves to connect endoscope to video cameras. For examination, diagnosis and therapy in conjunction with endoscopes in differ­ ent medical disciplines such as surgery, urology (transurethral resection), gyneco­ logy (myoma resection) and ENT by adequately trained and qualified medical personnel.

1

Contraindications directly related to the product are presently unknown. On the basis of the patient's general condition the doctor in charge must decide whether the planned use is possible or not. Side effects are not known if instruments are applied as defined in the intended use.

GA-S 022

Combinations

RIWO objective lenses are used in conjunction with endoscopes and CCD cam­ eras.

CAUTION! Do not combine products incorrectly! Injuries of the patient, user or others as well as damage to the product is possible. Combine the different products only if their intended uses and relevant technical data (working length, diameter, etc.) are the same. Follow the instruction manual of the products used in combination with this product.

.

NOTE! We recommend using a sterile objective lens. When using an unsterile objective lens, the sterilizable adapter 8580.91 can be connected between the endoscope and objective lens as an option to fasten the drape. This will allow subsequent endoscope changes without contaminating the sterile field (see section 7.6). Fig. 1 Adapter 8580.91 option

Checks CAUTION! Be careful if products are damaged or incomplete! Injuries of the patient, user or others are possible. Run through the checks before and after each use. Do not use the products if they are damaged, incomplete or have loose parts. Return damaged products together with any loose parts for repair. Do not attempt to do any repairs yourself.

8.1

Visual check

Z Check the RIWO objective lenses and accessories for ' damage ' sharp edges ' loose or missing parts ' rough surfaces Z Any lettering, labeling or identification necessary for the safe intended use must be legible. ' Missing or illegible inscriptions and labels that can lead to wrong handling and reprocessing must be reinstated. Z When screwing the objective lens onto the camera head or when connecting the endoscope, the glass surfaces of the connection must be dry and dustfree.

8.2

15

Function check

Z Check the individual components for compatibility. Z Check for secure connections. Z Check the individual instruments for easy assembly and proper functioning of the locking mechanism(s). Replace the instruments if the connection ' although locked is not secure. ' cannot be locked or is difficult to lock. Z Check the function of the snap-on mechanism (1) / clamping mechanism (2) or plug-on connection.

Manual cleaning

.

IMPORTANT! Manual cleaning is possible with the camera head in place. In the case of frequent use, unscrew the objective lens from the camera head once a week, clean the thread from any residues and apply 1 - 2 drops of oil. Remove any excess oil.

.

IMPORTANT! Do not clean the plastic parts with metal or sharp-edged tools (e.g. brushes). Fig. 18

Reprocessing procedures

The following tables contain a description of the reprocessing procedures for the indi­ vidual products validated by Richard Wolf.

GA-S 022

.

IMPORTANT! ' When used as intended and when the manual is observed it is not necessary to limit the number of possible reprocessing cycles. ' Careful and gentle handling during the entire reprocessing process has an es­ sential influence on the service life of medical products. ' Before being returned for repair, defective products must have gone through the entire reprocessing cycle. ' The user is obliged to make sure that the reprocessing process including the resources, materials and personnel is suited to yield the required results. ' Follow the national and international validation requirements.

.

IMPORTANT! Reprocess the products before every application and before returning for repairs as required by the instruction manual in order to protect the patient, user, and others.

.

IMPORTANT ! Do not sterilize RIWO objective lenses in hot-air sterilizers.

Product:

RIWO objective lenses, adapters and caps

Reprocessing guide: Preparation at the point of use:

Directly after use, remove any coarse soiling from the RIWO objective lens. Do not use any fixing or setting agents or hot water (>40C) as this will bake the residues to the surfaces and may have a negative impact on cleaning.

Transport:

Safe storage and transport of the instruments to the reprocessing room in a closed container to prevent damage to the instruments and contamination of the environment.

Precleaning:

No special requirements.

Cleaning:

Manual

Machine

See section 9.2.1, Fig. 18

Place the RIWO angular objective lens and caps in sieve tray of the washer-disinfector.

1.Immerse in a cleaning solution for at least 5 minutes, then brush inside. 2.Brush with a soft brush for at least 5 seconds to remove any residues. 3.Finally, rinse the RIWO objective lens, adapters and caps thoroughly with processed water and dry with a lintfree disposably cloth. 4.Clean the glass surfaces on the RIWO objective lens with a cotton swab soaked with alcohol (wooden or plastic swab carrier, not metal).

' Prewash for >4 min. with cold water ' Empty ' Wash for >6 min with a cleaning agent at 55C ' Empty ' Neutralize*) for >3 min with hot tap water (>40C) ' Empty ' >2 min of intermediate rinsing with hot tap water (>40C) ' Empty

Disinfection:

1.Immerse the RIWO objective lens, adapters and the Carry out thermal machine disinfection following the na­ caps in an approved disinfectant solution, exposure tional requirements regarding the A0 value (see DIN EN time as specified by the manufacturer. ISO 15883). 2. Finally, rinse the RIWO objective lens and caps thor­ oughly for at least 20 seconds with processed water**). 3.Clean the glass surfaces on the RIWO objective lens with a cotton swab soaked with alcohol.

High Level disinfection:

Cidex OPA, Cidex Glutaraldehyde

Drying:

Manual drying: Dry outside of RIWO objective lens, adapters and caps with a lint-free disposable cloth or swab or alternatively in a drying cabinet.

Function test, visual check maintenance:

Check visually for cleanliness. If necessary, repeat the reprocessing process until the RIWO objective lens, ad­ apters and caps are visually clean. ' Carry out a visual check: see section 8.1

Packaging:

Package the RIWO objective lens, adapters and caps for sterilization as required by the standards.

Sterilization:

Pre-Vac steam cycle at 270°F (132C) with 4 minutes exposure and 20-30 minutes dry time.
