Abstract:
1. A medical instrument for the treatment of tissue by means of high-frequency current, comprising: an elongate electrode carrier having a longitudinal axis, a distal region, a distal end and a proximal end; at least one electrode arranged at said distal end of said electrode carrier which electrode can be supplied with high-frequency current; at least one electro-magnetically acting position sensor arranged in said distal region of said electrode carrier immediately adjacent to said at least one electrode, said position sensor being arranged to produce an electrical signal when exposed to a magnetic field and thereby to sense at least one of a position and an orientation of said at least one electrode; and wherein said electrode carrier has two carrier parts arranged next to each other configured as two elongated thin rods, wherein the at least one electrode extends between the two rods at the distal end thereof, and said at least one position sensor is arranged at one of said two carrier parts, while an HF supply line for said electrode is arranged in the other one of said two carrier parts.
