One of the oldest methods used in minimally invasive surgeries is the transurethral resection. This is an operation technique in which diseased tissue from the bladder or the prostate is removed using a resectoscope through the urethra [Schostak M, Blana A, Hrsg. Alternative operative Therapien in der Uroonkologie. Berlin, Heidelberg, Springer Berlin Heidelberg; 2016]. A resectoscope has a channel for the view of the surgeon, a liquid supply, a working channel and a hand piece which could rotate up to 360 degrees. A RF- electrode on the tip of the resectoscope is used to cut out pathological growths. For diseased tissue which is located in the bladder on the ventral side, a rotation of the resectoscope up to 180 degrees is necessary. This means on the one side tiring of the hands, wrist pain and a change of the position of the operating surgeon. On the other side a reorganization of the connected tubes and cables is necessary. To avoid these problems and integrate additional features a standard resectoscope was adapted with an easy to use twist mechanism. After discussion with experienced urological surgeons a complete new design of the resectoscope with a twist mechanism in combination with a gyro sensor and a reference display was realized.
