title: Processing of surgical instruments for minimally invasive surgery.
abstract: Processing of surgical instruments for Minimally Invasive Surgery (MIS). General information on the development of Minimally Invasive Surgery and MIS instruments is given. The "MIS" scientific study group was formed to discuss and find solutions for design and hygienic problems in MIS. The article describes various groups of MIS instruments, i.e. disposable instruments, instruments with a cleaning channel, and instruments which can be dismantled. Aspects of how the instruments can be processed effectively will be discussed in detail, including an example of a survey carried out in a German hospital with a special monitoring method. Requirements are described for MIS instrumentation with regard to design, material, and surface conditions. Requirements for hygienic processing methods are listed. The article also describes the necessary control and confirmation of cleanliness, which proves to be a very particular problem. Conclusions on the present status of technology and the possibilities for future development with regard to the processing of MIS-instrumentation are given.
