전기 수술용 장치electrosurgical device
본 발명은 고주파 전류를 이용하여 조직의 응고, 지혈에 사용하는 의료 전기수술용 장치에 관한 것으로서, 더욱 상세하게는 고주파 전류가 조직에 침투되는 침투범위를 확장하여 수술대상부위에 대한 응고, 지혈 성능이 향상되는 전기수술용 장치에 관한 것이다. The present invention relates to a medical electrosurgical device used for tissue coagulation and hemostasis by using a high-frequency current, and more particularly, by expanding the penetration range through which the high-frequency current penetrates the tissue, coagulation and hemostasis performance for the surgical site It relates to an improved electrosurgical device.
일반적으로 전기수술용 장치는 전기를 이용하여 수술시 환부를 지혈하거나 응고하는데 사용하는 기기를 의미하며, 초기 전기수술용 장치는 전류가 흐르는 활성전극 자체가 고열로 발열되도록 하여 활성전극을 환부의 조직에 대어 환부조직에 대한 응고지혈이 이루어지도록 하였다. In general, an electrosurgical device refers to a device used for hemostasis or coagulation of an affected area during surgery using electricity, and the initial electrosurgical device causes the active electrode through which current flows to heat up due to high heat, thereby discharging the active electrode to the tissue of the affected area. It was designed to achieve coagulation and hemostasis of the affected tissue.
전기수술용 장치 품목에는 전기 수술기와 전기소작기가 있다. Electrosurgical device items include electrosurgical devices and electrocautery devices.
최근의 전기수술용 장치는 활성전극 자체가 발열되는 방식이 아니라, 활성전극을 통해 고주파(RF) 전류를 환부조직에 인가하여 환부조직에서 열이 발생되도록 하여 응고 및 지혈이 이루어지도록 하는 기술이 개발되어 사용되고 있다. The recent electrosurgical device is not a method in which the active electrode itself is heated, but a technology that applies a high-frequency (RF) current to the affected tissue through the active electrode to generate heat in the affected tissue to achieve coagulation and hemostasis. has been and is being used.
이러한 고주파(RF) 전류를 이용한 전기 수술용 장치는 단극방식과 양극방식이 있다. Electrosurgical devices using such a high-frequency (RF) current include a unipolar type and a bipolar type.
단극방식의 전기 수술용 장치는 수술자가 다루는 활성전극과 환자의 하체에 붙여진 접지판 사이에 고주파전류가 흐르게 된다. 조직에 인가된 고주파 전류는 직접 활성전극이 발열하는 것이 아니라 전극과 접촉된 조직에서 열이 발생된다. In a single-pole electrosurgical device, a high-frequency current flows between the active electrode handled by the operator and the ground plate attached to the patient's lower body. The high-frequency current applied to the tissue is not directly generated by the active electrode, but heat is generated in the tissue in contact with the electrode.
양극방식은 별도의 접지판이 필요하지 않으며 수술자가 다루는 전극부의 말단부에 활성전극과 비활성전극이 미세간격으로 배치되어 전극간 고주파의 이동으로 조직에 열을 발생시키게 된다. The bipolar method does not require a separate grounding plate, and the active and inactive electrodes are arranged at minute intervals at the distal end of the electrode handled by the operator, thereby generating heat in the tissue due to the movement of high frequency between the electrodes.
이러한 고주파 전류를 이용한 전기 소작기에 대해 등록특허 10-1379525호, 등록특허 10-1965766호 등에 개시되어 있다. It is disclosed in Patent Registration Nos. 10-1379525, Registration Patent Nos. 10-1965766 and the like for an electric cauterizer using such a high-frequency current.
등록특허 10-1379525호에는 고주파 전류를 통해 국부적으로 조직을 절개하거나 지혈하는 전기 소작 영역과 초음파를 발산하고 반사된 초음파를 수신한 정보 신호를 획득하는 초음파탐색 영역으로 구분된 전극팁과, 고주파 전류를 전극팁의 전기 소작 영역에 공급하는 전기 소작 제어부, 그리고 전극팁의 초음파 탐색 영역이 획득한 정보 신호를 전달받아 혈류 속도 및 혈류 깊이를 산출하여 혈관의 위치를 탐색하는 초음파 제어부를 포함하는 초음파 탐색 시스템을 내장한 전기소작기가 개시되어 있다. Patent No. 10-1379525 discloses an electrode tip divided into an electric cauterization area for locally incising or hemostasis tissue through a high-frequency current, an ultrasonic search area for emitting ultrasound and obtaining an information signal from a reflected ultrasound, and a high-frequency current Ultrasonic search comprising: an electric cauterization control unit for supplying to the electric cauterization region of the electrode tip; An electric cautery machine with a built-in system is disclosed.
또한, 등록특허 10-1965766에는 고주파 발생기로부터 인출되는 고주파 전류를 공급받아 고주파 전기 에너지를 발생시켜 신체 부위를 소작하는 전기소작기로서, 신체 부위에 접촉되는 전극판이 장착된 전극부 및 고주파 발생기를 통해 공급되는 고주파 전류를 전극판에 활성화시키는 통전 스위치가 장착된 파지부를 포함하며, 전극부에는 적어도 2개 이상의 전극판이 서로 다른 방향을 향해 배치된 의료용 전기소작기가 개시되어 있다. In addition, Patent No. 10-1965766 discloses an electric cauterizer that generates high-frequency electrical energy by receiving a high-frequency current drawn from a high-frequency generator to cauterize a body part, through an electrode unit equipped with an electrode plate in contact with the body part and a high-frequency generator. A medical electric cauterizer is disclosed in which at least two or more electrode plates are disposed in different directions to each other, including a holding part equipped with a energized switch for activating the supplied high-frequency current to the electrode plate.
하지만, 이러한 종래의 전기수술용장치는 전극부를 통해 신체부위에 고정된 주파수값을 갖는 단일의 고주파전류만이 인가됨으로써, 환부조직의 특정깊이에서만 세포조직의 응고 및 지혈이 이루어지기 때문에 환부조직의 응고 및 지혈이 조직 깊이방향에 대해 전체적으로 양호하게 이루어지지 않는 문제가 있었다. However, in this conventional electrosurgical device, only a single high-frequency current having a fixed frequency value is applied to the body part through the electrode, so that the coagulation and hemostasis of the cellular tissue are made only at a specific depth of the affected tissue. There was a problem that coagulation and hemostasis were not performed well overall in the depth direction of the tissue.
즉, 전극을 인체조직에 접촉시켜 인체조직에 고주파전류를 인가하는 경우, 인가되는 고주파전류의 주파수값에 따라 인체조직에 침투되는 깊이범위가 달라지고 이에 따라 조직의 깊이방향으로 발열위치가 달라지게 되어, 기존 전기수술용장치와 같이 설정된 특정주파수의 단일 고주파전류만이 전극을 통해 환부조직에 인가되는 경우, 단일의 고주파전류가 인체조직에 침투되는 범위가 한정됨으로써, 환부조직의 깊이방향에 대해 특정깊이에서만 발열이 이루어지고 응고 및 지혈이 조직 깊이방향으로 골고루 이루어지지 않아 전체적인 응고 및 지혈성능이 떨어지는 문제가 있었다. That is, when a high-frequency current is applied to a human tissue by bringing the electrode into contact with the human tissue, the depth range of penetration into the human tissue varies according to the frequency value of the applied high-frequency current, and accordingly, the heating position changes in the depth direction of the tissue. Thus, when only a single high-frequency current of a specific frequency set as in the existing electrosurgical device is applied to the affected tissue through the electrode, the range of penetration of a single high-frequency current into the human tissue is limited, so that the depth direction of the affected tissue is limited. There was a problem in that the overall coagulation and hemostasis performance was deteriorated because heat was generated only at a specific depth and coagulation and hemostasis were not evenly performed in the tissue depth direction.
