Abstract: In order to flush away local bleeding during surgery with a medical instrument, the instruments are commonly provided with a flushing device. In order to be able to control an inflow and outflow of a flushing liquid, the instruments have a stopcock. In order to achieve the sealing action of the stopcock, the plugs of the stopcock have to be formed with a very high degree of precision. The known production processes for such plugs are very cumbersome and cost-intensive. This provides a plug for a stopcock and a stopcock and a method for producing a plug, by way of which the stated problem is eliminated. This is achieved in that a plug, with a grip part and a cone part, is formed in one part and can be produced in a single process step.

The so determined working currents are used as input signals for an inverter controller, achieving improved control of the electrosurgical generator.

Abstract: Radiofrequency instruments such as the resectoscope described here are used in medicine for treating body tissue and in particular for removing or manipulating this tissue. A particular disadvantage of the known instruments is that an irrigation liquid is disturbed by an electrode instrument in such a way that the resulting turbulence limits the view of the operator. The invention makes available an electrode instrument by which this problem is solved. This is achieved by the fact that two electrode casing tubes run from an electrode to the proximal end region of the electrode instrument and each have a respective electrical contact, namely an active contact and a return contact.
