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.
