1.

Intended use

The micro-instruments are intended for use in neurosurgery, and are specially designed for use in narrow spaces. They can be used for cutting, grasping, dissecting, etc. of blood vessels and tissue.

2.

Indications

Dried and hardened or clotted surgical residues can complicate cleaning or render it ineffective and cause corrosion. Therefore, do not exceed a period of 1h between use and processing, make sure pre-cleaning temperatures are <45°C to prevent clotting, and do not use disinfectants that can cause clotting (active ingredient: aldehyde, alcohol). Excessive neutralizing agents or basic cleaners may result in a chemical attack and/or fading and the laser marking becoming unreadable either visually or by machine. Residues containing chlorine or chlorides, e.g., in surgical residues, medicines, saline solutions, and in the service water used for cleaning, disinfection, and sterilization, will cause corrosion damage (pitting, stress corrosion) and result damage to metallic products. These must be removed by rinsing thoroughly with demineralized water and then drying. Perform additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Material damage such as corrosion, cracks, fracturing, premature aging, or swelling. ► Do not use metal cleaning brushes or other abrasives that would damage the product surface and could cause corrosion ► For detailed information on hygienically safe and material-friendly/careful processing, please refer to www.a-k-i.org Header "AKI-Brochures", "Red brochure".

10.3 Reusable products There are no known effects of processing resulting in damage to the product. The product can be re-used up to 75 times with proper care and if it is undamaged and clean. Any additional reuse falls under the responsibility of the user. Careful visual and functional testing prior to next use is the best way to identify a malfunctioning product.

Indications, see Intended use.

Risks and side effects

As part of the legal obligation to provide information, the possible risks and side effects in connection with the use of surgical instruments known to the manufacturer are highlighted below. These are predominantly process-specific, not product-specific, and include unwanted damage to surrounding tissue, such as bleeding, infection, incompatibility of materials, or parts of instruments left unnoticed in the patient.

5.

Available sizes

► If applicable, rinse surfaces that are not accessible to visible inspection (preferably with demineralized water),

using a disposable syringe, for example. ► Remove any visible surgical residues as much as possible with a damp, lint-free cloth. ► Place the wet product in a sealed waste container and take it to be cleaned and disinfected within 1h.

10.6 Preparation before cleaning ► Dismantle the product prior to cleaning, see Disassembling.

10.7 Cleaning/disinfection 10.7.1 Product-specific safety notes on the reprocessing procedure

The micro-instruments are available as complete instruments and as separate, combinable components. Various jaw parts (e.g. straight scissors, curved scissors or forceps) can be used with the appropriate handles.

Danger to the patient! ► Reprocess the product only with manual pre-cleaning followed by mechanical cleaning.

Note The current product range is described in Aesculap brochure C 74511.

► Ensure that the product and its accessories are operated and used only by persons with the requisite training,

knowledge, or experience. ► Read, follow, and keep the instructions for use. ► Use the product only in accordance with its intended use, see Intended use. ► Remove the transport packaging and clean the new product, either manually or mechanically, prior to its initial sterilization. ► Store any new or unused products in a dry, clean, and safe place. ► Prior to each use, inspect the product for loose, bent, broken, cracked, worn, or fractured components. ► Do not use the product if it is damaged or defective. Set aside the product if it is damaged. ► Replace any damaged components immediately with original spare parts.

7.

DANGER Damage to the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfecting agents according to the manufacturer’s instructions which – are approved for (e.g. aluminum, plastics, high-grade steel), – do not attack softeners (e.g. in silicone). ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum cleaning temperature of 55 °C.

CAUTION

Safe operation Risk of injury and/or malfunction! ► Always carry out a function check prior to using the product.

► Use suitable cleaning/disinfecting agents if the product is put away in a wet condition. To prevent foam forma-

tion and reduced effectiveness of the process chemicals: Prior to mechanical cleaning and disinfection, rinse the product thoroughly with running water. ► Clean and disinfect microsurgical products mechanically if they can be placed securely in the machine or on the positioning aids.

10.8 Mechanical cleaning/disinfection with manual pre-cleaning WARNING

8.

Disassembling

► Turn the locking knob 1 by 180° so that it disengages. ► Hold the handle stems 2 with one hand and the jaw parts with notched rod 4 with the other hand. ► Pull to separate the jaw part mounting 3 and the jaw parts with notched rod 4. ► Turn the locking knob 1 back to its original position.

9.

Note As a matter of principle, the efficacy of the cleaning and disinfection device must be certified (e.g. in accordance with EN ISO 15883). Note The cleaning and disinfection machine used for processing must be serviced and checked at regular intervals.

► Ensure that the bridge of the jaw part 4 and the groove in the jaw part mounting 3 are in the same axis when

the handle stems 2 are in closed position. ► Push the jaw part mounting 3 and jaw parts with notched rod 4 together until the notched rod engages with an

audible click. ► Function check: Press the handle stems 2 together, all the way to the stop.

Check that the jaw parts operate properly.

10.1 General safety notes Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for reprocessing. Note For patients with Creutzfeldt-Jakob disease (CJD), suspected CJD, or possible variants of CJD, observe the relevant national regulations concerning the reprocessing of products. Note It should be noted that successful reprocessing of this medical device can only be guaranteed following prior validation of the reprocessing method. The operator/reprocessing technician is responsible for this. The specified chemistry was used for validation.

Phase I ► Clean the product in the solution using a suitable cleaning brush until no residue is visible on the surface. ► If applicable, use a suitable cleaning brush to brush any surfaces that are not visible for at least 1 min. ► Mobilize non-rigid components, such as set screws and hinges, during cleaning. ► Then flush these areas thoroughly at least five times with the cleaning disinfectant solution using a disposable syringe (20 ml). Phase II ► Rinse/flush the instrument thoroughly (all accessible surfaces) under running water. ► Mobilize non-rigid components, such as set screws and hinges, during rinsing.
