Definitions
- the present invention relates to an electrode body used to locally remove tissues of a specific part of the body using a radio frequency (RF).
- RF radio frequency
- the direction of the electrode control the direction of the electrode body can be easily removed to remove the tissue of the desired position, it is possible to easily penetrate the blocked solid fibers
- the present invention relates to an electrode body capable of adjusting a direction.
- the present invention relates to an induction tube that can be easily inserted into the site of the body tissue to be removed.
- intervertebral disc herniation occurs, intervertebral discs in the spine protrude, compressing adjacent nerves, causing back pain and radiating pain in the lower extremities.
- the intervertebral disc consists of the nucleus pulposus and the annulus fibrosus.
- the nucleus pulposus flows out between the inner wall of the torn fiber ring due to the pressure generated by weight or excessive impact during a long standing position.
- the high pressure inside the intervertebral disc is transmitted to the intervertebral disc sheath so that a part of the intervertebral disc protrudes. This is called disc herniation.
- the protruding intervertebral disc portion does not return to its original state, thereby maintaining a continuously protruding shape, which causes pressure on the nerves near the spine to cause back pain.
- the intervertebral disc herniation can also be treated by surgical operation.
- surgical surgery can provide as much as 30% of surgical patients.
- 5-10% of surgical patients suffer from Failed Back Surgery Syndrome (F.B.S.S), because surgical procedures involve the removal of spinal nerves.
- F.B.S.S Failed Back Surgery Syndrome
- Another approach to treat intervertebral disc herniation is to remove the nucleus constituents in the intervertebral disc to reduce the pressure inside the intervertebral disc, thereby restoring the protruding portion of the intervertebral disc to spontaneously reconstruct into the intervertebral disc.
- a radiofrequency electrode is inserted into the intervertebral disc, and then a radiofrequency is applied to the tissue around the electrode using a radiofrequency to generate electrons and positive charges.
- There is a method of removing in a gaseous state separated by ions The method of removing tissue in the body by using a radiofrequency electrode can reduce the hospital stay in hospital, significantly reduce the cost of surgery and reduce the risk of side effects after surgery compared to surgical surgery.
- the radio frequency is a frequency range of 100 ⁇ 20,000kHz.
- a method for removing or removing human tissue and removing waste products from blood vessels using a radiofrequency electrode is disclosed in US Pat. No. 6,554,827 B2.
- the outer skin of the protrusion of the intervertebral disc is subjected to hydrostatic pressure by the inner composition of the protrusion. Since the fluidity of the inner composition of the protrusions is not large, the nerve roots are continuously pressed while maintaining the protruding shape, and low back pain occurs continuously. At this time, the radiofrequency electrode tip guided through the guide tube is placed in the inner composition in the outer skin of the intervertebral disc protrusion.
- Conventional radiation frequency electrodes have a straight line shape, and thus reach only the portions at the insertion position and the straight position into the body, thereby limiting the access portion in the body.
- the position where the radiofrequency electrode tip can be inserted is very limited. This makes it very difficult to remove the tissue site across the insertion position of the radiofrequency electrode.
- the method of using the radiofrequency electrode is a principle of restoring the intervertebral disc portion escaped by the sound pressure generated by removing the tissue.
- failing to remove the tissue near the escaped site would result in extremely poor efficiency.
- the radio frequency electrode bent in a predetermined curvature in advance through the induction tube through the induction tube using a restoring force to reach a part that is difficult to approach straight.
- the bending and the like of the part which once entered into the body are restored as predetermined, it is difficult to be widely applied because it has risks due to skill or guesswork.
- it is difficult to remove the tissue at the radiation frequency by accurately positioning the electrode on the escaped intervertebral disc region, which is different for each individual.
- a neck may be formed between the original annulus and the protruding portion, and tissue may grow into the narrow portion over time. It is a solid fiber.
- the electrode tip is difficult to penetrate the obstructed solid fiber, making it difficult to remove the nucleus pulposus inside the disk hernia.
- the present invention has a direction control function for easily positioning the treatment means to a specific part of the tissue in the body, to provide a treatment means that can exhibit a therapeutic effect through the selective removal of body tissues.
