Abstract
An endotracheal tube is introduced into the trachea using a video introducer in the form of a bendable rod having a camera and light source at one end and connected to a display monitor via a cable and connector at the other end. The introducer is initially inserted to the trachea carrying a guide sleeve extending along its outside. When correctly inserted, the video introducer is removed by pulling rearwardly to leave the guide sleeve in position. The endotracheal tube is then slid into position along the guide sleeve, following which the guide sleeve is removed to leave the endotracheal tube in position. The guide sleeve could be stiffened after removing the video introducer and before inserting the tube by inserting a stylet or filling the sleeve with a substance.

- 13. A medico-surgical assembly including an elongate viewing device arranged to view an anatomical site at its forward end and to provide an output at its rear end representative of an image of the anatomical site, characterised in that the assembly includes a sleeve slidably mounted on the outside of the viewing device and extending from a region adjacent its forward end along a major part of the length of the viewing device that the viewing device is removable rearwardly from within the sleeve after correct positioning of the viewing device such as to leave the sleeve in position, and that the assembly includes tubular apparatus slidably mounted along the outside of the sleeve after removal of the viewing device such that the tubular apparatus can be slid to the desired position viewed by the viewing means and the sleeve subsequently removed from within the tubular apparatus leaving the tubular apparatus in position.

23. A technique for introducing a medico-surgical tube into the body including the steps of introducing an assembly including a viewing device into the body under visual monitoring from an output of the viewing device, the assembly having a sleeve slidably extending along the outside of the viewing device, subsequently withdrawing the viewing device but leaving the sleeve in the body in the desired position, then sliding the medico-surgical tube along the outside of the sleeve so that it too is located in the desired position in the body, and subsequently removing the sleeve from within the tube to leave the tube in position.
