Abstract: A radiofrequency electrode for handheld devices are used predominantly in urology for electrosurgical work in the bladder, the prostate, and the urethra. A large active area of the electrode is known to be advantageous. However, the size of the area is restricted by the available space. Moreover, greater energy is required for igniting the plasma for large electrodes. However, an elevated energy level is disadvantageous in terms of the heat influx into the rinsing liquid and this may be disadvantageous for the surrounding tissue. The invention develops a radiofrequency electrode, an electrode instrument and a resectoscope, in which a plasma can be better localized at the electrode and the energy for igniting the plasma is reduced at the same time. This is achieved by virtue of a radiofrequency electrode for use in a surgical handheld device having the shape of a toroid.

Abstract: A surgical instruments can be carried out via a foot switch by an operator or a surgeon. It is typical that during operation, multiple surgical instruments are each operated via one foot switch. As a result, the risk of an incorrect operation of the foot switches increases because the space available for the placement of the foot switches is limited. The invention provides a method and a device using which various functions in connection with surgical instruments can be carried out in a simple and safe manner. This is achieved in that at least one projector for generating a virtual control panel and at least one sensor for acquiring the virtual control panel are assigned to a foot switch.
