A method and a system for simulating the minimally invasive medical procedure of urological endoscopy. The system is designed to simulate the actual medical procedure of urological endoscopy as closely as possible by providing botha simulated medical instrument, and tactile and visual feedback as the simulated procedure is performed on the simulated patient. Particularly preferred features include a multi-path solution for virtual navigation in a complex anatomy, the simulation of the effect of the beating heart on the urethra as it crosses the illiac vessel, and the simulated operation of a guidewire within the urethra In addition, the system and method optionally and more preferably incorporate the effect of dynamic contrast injection of dye into the urethra for fluoroscopy. The injection of such dye, and the subsequent visualization of the urological organ system in the presence of the endoscope, must be accurately simulated in terms of accurate visual feedback. Thus, the system and method provide a complete solution to the complex and difficult problem of training students in urological endoscopy procedures.

An endoscopy suite is adaptable for carrying out a plurality of endoscopy procedures and / or for supporting several endoscopes being used simultaneously in a given procedure. The endoscopy suite comprises a memory unit in which are stored a plurality of predetermined sets of parameters. Each of these sets comprises a unique set of parameters for each of a plurality of endoscopic procedures. Once a specific endoscopic procedure has been selected by the operator of the endoscopy suite and one or more endoscopes appropriate for carrying out the specific endoscopic procedure has been connected to the endoscopy suite, then the set of parameters appropriate to the specific procedure are transferred automatically to a controller, which controls the operation of the components of the endoscopy suite to provide the predetermined lighting, suction, and insufflation pressure levels for the selected endoscopy procedure.

A pressure monitoring device is provided for use with a tool such as a medical endoscope. The device includes a housing which is fluidically coupled with an internal volume of the endoscope. A pump is used to change the pressure inside the device housing and endoscope, thereby establishing a pressure differential from the ambient environment. During an endoscopy procedure, the pressure inside the device housing is monitored, and a change in pressure exceeding a predefined limit causes an alarm signal indicating a leak has occurred in the endoscope. The device housing may be directly mounted to the endoscope, located remotely and connected with a coupling tube, or integrated with an accessory device connected to the endoscope. The pump may be integrated internally to the device housing, or it may be a separate external pump which is connected to the housing. The pressure differential may be positive or negative relative to ambient.
