An apparatus for simulation of an endoscopy operation. A dummy endoscope () is inserted into a unit () which monitors the position of the dummy instrument and provides force feedback to the instrument in accordance with a stored software model. A virtual image simulating the view from the endoscope is displayed. Additional simulation is provided of an external condition to the patient body, for example patient orientation (), external pressure applied to the body (), () and trans-illumination ().

Method and apparatus for simulation of an endoscopy operation

An optical assembly 7, 8 providing an optical relay of a borescope 1 has a plurality of lenses 7 spaced apart by tubular spacers 8 through which the optical path extends. The spacers 8 include formations 9, 10 and 11 for connecting adjacent spacers and for housing the lenses 7 such that the spacers 8 and the lenses form a self supporting assembly. The optical assembly 7, 8 locates in a window tube 19 located within a tubular shaft 2 with a fibre optic bundle 16 occupying a duct 17 formed between the window tube and the shaft. The borescope 1 is convenient to assemble with minimum contamination and maximizes the optical path cross sectional area available.
