8、BS ISO 8600-6:2005ii iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
9、 a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commiss
10、ion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical
11、committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall
12、not be held responsible for identifying any or all such patent rights. ISO 8600-6 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 5, Microscopes and endoscopes. ISO 8600 consists of the following parts, under the general title Optics and photonics Medical endosc
13、opes and endotherapy devices: Part 1: General requirements Part 2: Particular requirements for rigid bronchoscopes Part 3: Determination of field of view and direction of view of endoscopes with optics Part 4: Determination of maximum width of insertion portion Part 5: Determination of optical resol
14、ution of rigid endoscopes with optics Part 6: Vocabulary BS ISO 8600-6:2005blank 1Optics and photonics Medical endoscopes and endotherapy devices Part 6: Vocabulary Scope This part of ISO 8600 defines terms for endoscopes and endotherapy devices commonly used in the endoscopic area. 1 Types of endos
15、copes 1.1 endoscope medical instrument having viewing means, with or without optics, introduced into a body cavity through a natural or surgically-created body opening for examination, diagnosis or therapy NOTE 1 Endoscopes may be of rigid or flexible type; all types may have different image pick-up
16、 systems (e.g. via lenses or ultrasonic sensors) and different image-transmitting systems (e.g. optical, via lenses or fibre bundles, or electrical). NOTE 2 IEC 60601-2-18 deals with electrical safety aspects of endoscopic systems and therefore the endoscope is regarded as an applied part of medical
17、 electrical equipment introduced into a patient. In IEC 60601-2-18:1996, the endoscope is defined as the “applied part of medical electrical equipment introduced into a patient to provide an internal view or image for examination, diagnosis and/or therapy”. 1.2 fiberscope endoscope (1.1) in which th
