1. An epidural catheter with an RF generation function, comprising:
a main body;
an inserting part being connected to the main body and configured to be inserted inside a physical body; and
a manipulating part being provided in the main body and being connected to the inserting part or an internal assembly part of the inserting part, so as to manipulate the inserting part or to perform a function of the inserting part,
wherein two steering wires are interpolated in the inserting part, the two steering wires being manipulated by the manipulating part so as to allow flexion of the inserting part to be controlled,
wherein first and second electrodes are coupled to distal ends of the two steering wires, respectively, and the first and second electrodes are symmetrical and spaced apart from each other,
wherein each of the first and second electrodes has a half dome shape such that the first and second electrodes in combination form a dome,
wherein the first electrode has a first semicircular recess and the second electrode has a second semicircular recess such that the first and second recesses in combination form a circular hole,
wherein the circular hole is provided at a most distal end portion of the dome formed by the first and second electrodes in combination.
