Medical instruments: Operating instructions, recommended maintenance, cleaning and sterilization

The instruments may only be used for their designated purpose, for which the product catalogue gives recommendations. Diagnostic, surgical and dental hand instruments made of stainless steel manufactured and distributed by MEDICOR Hand Instruments belong to Class I (risk category I). According to 4/2009. (III.17.) EüM. regulation 9 surgical instruments are suggested to be used temporarily by the manufacturer and distributor, MEDICOR Hand Instruments Co. Avoid cutting thick tissues, textiles and suturing materials with fine preparing scissors, or compressing tubes with artery clips. Only load the instruments with forces suitable for their structure and cross-section. Protect the fine edged and pointed instruments from being thrown or accidentally dropped, it is expedient to handle these implements separately from the traditional ones. When handling the instruments special care must be taken that they do not heat up to over 200 C (mainly with hot-air sterilization), because this is accompanied by a loss in their hardness and working life. For avoiding corrosion, the instruments should be dried as soon as possible after use and washing, never store the instruments for a long period in a closed, wet place.
Attention: the instruments are delivered in a non-sterile condition!
1. New instruments must be cleaned, dried and sterilized before being used. As the spaces between moving parts are small on the new instruments, after cleaning they must be left to dry in the air, and the connecting parts and rubbing surfaces of the springs must be lubricated with a few drops of acid-free oil. Before operating they should be left for a few minutes so that the oil infiltrates between the rubbing surfaces. Lubrication of the instruments must be carried out after every cleaning (only a few drops of oil should be used).
2. Rinsing: The instruments must be rinsed immediately after use in warm, running water (not hot). The rinsing removes the blood and the tissues.
3. Cleaning: If this is not carried out immediately after rinsing, the instruments must be soaked in a neutral (pH7) diluted solvent. The cleaning can take place in an ultrasonic washing appliance, in an automatic washing appliance and by manual methods. It is expedient to clean delicate instruments, for example microsurgical instruments by hand. For this we should use a soft synthetic cleaning brush and only neutral (pH7) solvent. Independent of the washing method the instruments should always be washed and rinsed in the open condition. Only use disinfecting and cleaning solutions, which have been developed for this purpose. Do not use wire brushes or buffing materials for the cleaning. In the case of ultrasonic cleaning, fix the instruments to the tray. Do not clean instruments made from carbon steel or nickel and chrome plated instruments together with the MEDICOR’s stainless steel instruments. When cleaning observe the manufacturer’s instructions.
4. Rinsing, drying: After cleaning, the instruments must be rinsed in running water opening and closing them a few times, then rinse them in distilled or deionised water. Dry the instruments then lubricate the moving parts, and inspect their operation and condition. Do not use industrial oil for the lubrication, only use oil manufactured for lubricating surgical instruments. Inspect the following:
The scissor blades slide smoothly over the full length, and are not slack in the closed position.
Check the cut on thin gauze.
The blades cut from three quarters of the length, to the tip.
The tweezers tips cover each other.
There is no space between the cheeks of forceps and needle holders, they should open and close easily, the connecting part are not slack, and the cheeks match each other.
Inspect the wear on the internal cheek surface of needle holders.
Cutting instruments and knifes must have sharp, undamaged blades.
5. Sterilization: The MEDICOR instruments stand up to all sterilization processes up to 200 C. When sterilizing a set, place the instruments on a special corrosion-resistant tray. If there are several trays, place the heaviest at the bottom. Never close the instruments during autoclaving. If the vapour cannot reach the metal surface, then this will not be sterile. Always observe the manufacturer’s instructions when sterilizing.
Reminder: The stainless steels are only corrosion-resistant under ideal circumstances. If the instruments manufactured from modern corrosion-resistant steel are handled correctly, they will have a long working life. The out of use instruments should be stored in a dry room free from acid and alkaline vapours. The repairs to natural wear arising during use of the instruments may only be carried out by a specialist.

ATTENTION! The incorrect handling and care, together with incorrect use of the products can lead to them wearing out prematurely. The delivered products are not sterile!! First use of the new instruments The delivered instruments are not sterile; the user must make provision for their cleaning and sterilization before use. Examination and inspection of correct operation Before every occasion of use the products must be inspected to check that they are not fractured, not bent, and operate satisfactorily. Special care must be taken in regard to the inspection of the blades, tips, matching, closing and fixing components, and all movable components. The parts exposed to wear (e.g. pipes, cutting edges) must similarly be inspected. If the product is dismantled, then after reassembly attention must be paid to its faultless operation, and to the fact that every screw and component matches securely. Cleaning and care Every product must be cleaned thoroughly after use, with particular regard to the gaps, matching components and every place that is difficult to reach. As the last rinsing process the instruments must be thoroughly rinsed with water not containing mineral materials (distilled or deionised water). Products, which can be dismantled, must always be cleaned in the dismantled condition. The products must be dried immediately after washing and rinsing. After every cleaning the products must be treated with suitable and physiologically permitted oil before the sterilization. Here also particular care must be taken with the edges, matching and rubbing parts, fixing parts and moving components. We recommend ‘sterilizing with steam’ as the sterilizing process. The DIN 100 (Correct preparation of instruments / appendix) serves as the basis for this. Handling Every product must be handled with the necessary care. Suitable measures must be taken in the interest of protection against damage arising during the transport, cleaning, tending, sterilization and storage. The products can be corroded and their operation harmfully influenced if they come into contact with aggressive materials. Do not expose the instruments to the effect of strong cleaning materials or acids. Incorrect handling results in cancellation of the guarantee!!
