Surgical motor systems
Which sterilization methods can be used for motor systems?
In general, make sure that sterilisation procedures approved by the manufacturer are used. This is usually the fractioned vacuum process at 134°C / 2 bar and 5 minutes minimum holding time. If a programme with an extended holding time, e.g. 18 minutes, is to be run, the instructions for use or the respective machine manufacturer should always be consulted in advance.
What should be taken into account when preparing to reprocess surgical motor systems?
Attached adapters, tools, hoses, etc. must be removed before reprocessing
Which cleaners / disinfectants are suitable for motor systems?
When selecting the detergents/disinfectants, care must be taken to ensure that products do not attack plasticisers as this would lead to seals used becoming brittle. If there are components made of aluminium or anodised aluminium, steps must be taken to ensure that the detergent/disinfectant is suitable for aluminium and that a pH < 11 is ensured in the wash liquor.
Can motor systems be reprocessed mechanically?
The general mechanical reprocessing of motor systems is not possible. Today, manufacturer-specific solutions are offered for most new motor systems. For older systems, however, machine reprocessing is often not possible. In general, care must be taken to ensure that reprocessing always follows the manufacturer's instructions.
Can motor systems be immersed or cleaned in an ultrasonic bath?
Immersing motor systems and their components in disinfectants/cleaning agents is not usually possible - exceptions are e.g. some compressed air hoses which can be connected and simple accessory components such as tools.
Can compressed air be used to dry motor systems after cleaning?
Compressed air can be used to blow dry the surfaces of motor systems. However, care must be taken to ensure that compressed air is never aimed at bearing seats, i.e. areas from which rotating or other moving parts protrude must not be blown dry with compressed air. There is a risk that the highly concentrated pressure could damage seals and/or force liquid into the machine interior.
Can oil/oil spray be used for the maintenance of motor systems?
In general it is important to ensure that only the oil/lubricants approved by the respective manufacturer are used. This is the only way to ensure that there are no material changes to seals and hoses or any intraoperative heating of handpieces/engines caused by ingredients of the oil/oil spray.
