The present invention discloses a surgical navigation tool having a needle electrode depth control structure with impedance detected and a high-frequency energy control method using the same. According to the present invention, while a pilot signal for impedance detection is applied to an electrode of a high-frequency needle, impedance on a tissue to be treated is detected by using a method corresponding to an impedance status on the tissue to be treated and the applied amount of high-frequency energy outputted to the high-frequency needle according to the detected impedance is determined. Accordingly, when the number of skin insertions by the high-frequency needle with adjustable penetration depth is selected and surgical procedures are performed by using identical or different procedure parameters dependent on a symptom of a disease, the pain of a patient caused by high-frequency energy applied to different depths at the same spot for surgical procedure is reduced to maximize the effects of the surgical procedures and shorten a time for the surgical procedure. According to the present invention, the surgical navigation tool comprises: a needle module including a plurality of high-frequency needles inserted into the tissue to be treated; a handpiece joined to the needle module; an impedance detection unit connected through the handpiece to the electrode of the high-frequency needle to detect an impedance on the tissue to be treated; and a control unit connected through the handpiece to the needle module to control the high-frequency needles such that the high-frequency needles have the same or different penetration depths at the tissue to be treated. 본 발명은 임피던스가 검출되는 니들 전극 깊이 조절 구조를 가진 수술 내비게이션 도구와 이를 이용한 고주파 에너지 제어방법을 개시한다. 이러한 본 발명은 시술조직의 임피던스 상태에 따르는 방식으로서 고주파 니들의 전극에 임피던스 검출을 위한 파일롯 신호를 인가하면서 시술 조직의 임피던스를 검출하고 검출된 임피던스에 따라 고주파 니들에 출력되는 고주파 에너지 인가량을 결정하도록 구성한 것이고, 이에 따라 침투 깊이 조절이 가능한 고주파 니들의 피부 삽입 횟수를 선택하면서도 병증에 따라 동일 또는 서로 다른 복수의 시술 파마미터로 시술이 진행시, 동일한 시술 점에서 서로 다른 깊이에서 인가되는 고주파 에너지에 따른 환자 통증을 줄여 시술 효과를 극대화시키고, 시술 시간을 단축하는 것이다.
