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

The dilator has a central bore for a guide wire and a flexible distal portion merging continuously with an intermediate portion of constant cross-section. A proximal portion is convex in profile and merges continuously with the intermediate portion. The distal portion comprises a hemispherical tip followed by a conical section, a concave section and a convex section, respectively. The dilator is primarily for dilating oesophageal strictures when used in conjunction with an endoscope to place the guide wire and is urged along the wire using a threadably engaged insertion rod.
