Embodiment Construction

[0043]The invention provides a direction-controllable electrode body, which includes a flexible body, and the flexible body includes: a first electrode, which includes a main body, a first cap connected to one end of the main body, and a cap connected to the other end of the main body. A first electrode wire; an insulator, which is connected to the main body of the first electrode and the first cap part, and the function of the insulator is to insulate the first electrode from the second electrode; a first ring connected by an insulator and a second electrode wire connected to one end of the first ring; a direction controller comprising a first direction control wire connected to the first or second electrode to The orientation of the electrode body is controlled.

[0044] The direction-controllable electrode body may further include a rigid body connected to the flexible body.

[0045] In this case, the direction-controllable electrode body may further include a first direct...

Abstract

Disclosed is a direction controllable electrode body, comprising a flexible body which comprises: a first electrode, comprising a body, a first cap joined to one end of the body, and a first electrode line connected to the other end of the body; an insulator in partial contact with the body and the first cap of the first electrode, said insulator functioning to insulate the first electrode from the second electrode; a second electrode, comprising a first ring in contact with the insulator, and a second electrode line connected to one end of the first ring; and a direction controller, comprising a first direction controlling wire communicating with the first electrode or the second electrode to control direction of the electrode body. Also, a guide pipe is provided for leading the electrode body to a target tissue.

Description

technical field [0001] The present invention relates to an electrode body useful for localized removal of body tissue using radio frequency (RF). More specifically, the present invention relates to a direction-controllable electrode body that can easily penetrate hard fibrous substances in the body and further reach targets within the substance in a controlled manner using control wires organize. Furthermore, the present invention also relates to a catheter that can guide said electrode body to a target tissue of the body. Background technique [0002] A herniated disc is a condition that damages the spine by putting pressure on the nerves near the disc, causing pain in the lower back and spinal nerve roots. The intervertebral disc consists of an outer fibrous annulus surrounding the inner nucleus pulposus. After the annulus is squeezed by physical impact, the nucleus pulposus protrudes from the fissure of the annulus when the intervertebral disc bears a lot of pressure g...
