The work of preparing International Standards is normally carried
10、 out through ISO technical committees. Each member body interested in 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
11、 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different
12、approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 www.iso.org/directives. Attention is drawn to the possibility that some of the elements of this document may be the su

21、opic element with a sharp pyramidal or conical point used to puncture body cavities Note 1 to entry: It is typically assembled and used together with a compatible trocar sleeve filling its lumen, allowing the introduction of this assembly. Following puncture the trocar pin is withdrawn providing a w

26、loons, controllable parts, jaws and the like having variable insertion portion widths. Note 2 to entry: See also ISO 8600-6:2005. SOURCE: ISO 8600-1:2013, definition 3.10 4 Dimensions 4.1 General There is a wide range of trocar sleeves as well as endotherapy devices used with trocar sleeves with dif
27、ferent dimensions available. If the nominal diameter of an endotherapy device is smaller than the nominal diameter of the sleeve, the usage of both together is obviously possible without problems. In order to keep the incision small, trocar sleeves and endotherapy devices may have the same nominal d
28、iameter. In this case it is very important to ensure that the endotherapy device can be introduced through the sleeve. Thus, the maximum insertion portion width (OD) of the endotherapy device shall be smaller than the minimum inner diameter (ID ts,min ) of the trocar sleeve. 4.2 Trocar pin and troca

These devices have branches without joint, see Figur
37、e 6. In this case the inner part has to be moved forward within the sheath to open the branches, or the sheath has to be moved backwards for opening. This means, the user has to take care of the relative movement of the distal part. Another disadvantage is the maximum opening of the branches, which
