摘要
The invention relates to a device for positioning a guiding tube (1) for a nephroscope, said tube consisting of a long aspiration needle (2) which is provided with a closing mandrin (3) and on which an inflatable enlargement device (4) slides, said device especially comprising a cuff (25) which is positioned by sliding along the aspiration needle (2) that is previously inserted into the kidney of the patient. The operation is facilitated by a trocar consisting of cutting blades (19) which enlarge the opening without tearing any flesh. The cuff is then inflated so that the inflatable enlargement device (4) can be used as a guiding means for a guiding tube for a nephroscope during the positioning thereof in the kidney of the patient.
