The conventional fibre optics in a cystoscope is replaced by a scanning device by which it is possible to obtain an ultrasonic scanning picture of the interior of a human body, especially the bladder and the prostate region. Essentially, the scanning device comprises an elongated tube mounted on a stepping motor. From the distal end of this tube a cautery electrode protrudes, the distal end further being provided with a transducer for pulse-echo ultrasonic exploration. |
