Description

고주파 열치료용 비대칭 바이폴라 전극침Asymmetric Bipolar Electrode Probe for High Frequency Thermal Therapy
본 발명은 신체 기관의 암조직 등 병변부위를 고주파로 가열함으로써 소작하여 괴사시키는 고주파 열치료용 전극침에 관한 것으로, 더욱 상세하게는 바이폴라 방식으로 전극이 배치되어 소작 방향과 속도 및 범위를 조절할 수 있는 고주파 열치료용 비대칭 바이폴라 전극침에 관한 것이다.The present invention relates to an electrode needle for high frequency thermal therapy that is cauterized and necrotic by heating a lesion such as cancerous tissue of a body organ at high frequency. More specifically, the electrode is arranged in a bipolar manner to control the cauterization direction, speed, and range. The present invention relates to an asymmetric bipolar electrode needle for high frequency thermal therapy.
일반적으로 신체 기관, 예를 들면 간과 같은 기관에 암조직 등이 발생되면 비수술적인 방법이나 외과적인 수술에 의해 치료하고 있다.In general, when cancer tissues occur in body organs such as the liver, they are treated by non-surgical methods or surgical operations.
이때, 외과적인 수술은 주로 병변부위의 신체를 절제하여야 하므로 그 부위가 매우 넓어 큰 흉터를 남기게 되고, 또 많은 요양기간을 필요로 하는 등의 문제가 있다.At this time, the surgical operation is mainly to remove the body of the lesion site, so that the area is very wide, leaving a large scar, there is a problem such as requiring a long period of care.
또한, 암조직 등이 재발할 가능성이 있으며, 재발한 경우에는 재수술을 해야 하므로 환자에게 고통은 물론 경제적 부담과 위험성이 큰 단점이 있다.In addition, there is a possibility that cancer tissues, etc., recur, if the recurrence has to be re-operated, there is a significant disadvantage as well as economic burden and risk to the patient.
따라서, 최근에는 비수술적인 방법, 예를 들면 경동맥화학색전술, 경피적에탄올주입법, 전신적항암화학요법, 국소적열치료 등이 이용되고 있으며, 이 중 국소적열치료가 단기 치료성적이나 장기적 생존율 향상에 가장 효과적인 것으로 알려져 있다.Recently, non-surgical methods such as carotid artery embolization, percutaneous ethanol injection, systemic chemotherapy, and topical heat therapy have been used. Known.
국소적열치료에는 고주파 열치료, 마이크로웨이브 소작술, 레이져 소작술 등이 있으며, 이 중 고주파에 의한 열치료가 가장 효과적으로 이용되고 있다.Local heat therapy includes radiofrequency ablation, microwave ablation, and laser ablation. Among these, radiofrequency ablation is most effectively used.
여기서, 고주파 열치료는 신체 기관, 예를 들면 간에 암조직이 발생하게 되는 경우, 이를 절제하지 않고 암조직만을 고주파 열에 의해 소작하여 괴사시키는 치료방법이다.Here, the high frequency heat treatment is a treatment method in which the cancer tissue is cauterized by high frequency heat without necrosis, when cancer tissue is generated in the body organs, for example, the liver.
이러한 고주파 열치료를 위한 전극장치는, 도 1에 도시된 바와 같이, 시술자가 파지하는 손잡이(5)의 전방으로 전극침(6)이 조립되고, 전극침(6)에는 고주파를 공급하는 전극라인(4)과 냉각수를 순환 공급하는 냉각라인(3)이 연결된다.In the electrode device for high frequency heat treatment, as shown in FIG. 1, an electrode needle 6 is assembled in front of a handle 5 held by an operator, and an electrode line for supplying high frequency to the electrode needle 6. (4) and the cooling line 3 which circulates and supplies cooling water are connected.
이때, 통상적으로 전극침(6)의 선단부에 통전부(6a)가 형성되고, 나머지 부분은 절연부(6b)를 형성한다.At this time, normally, the electricity supply part 6a is formed in the front-end | tip part of the electrode needle 6, and the remainder part forms the insulation part 6b.
그리고, 시술자는 전극침(6)을 신체 기관의 암조직과 같은 병변부위를 관통하도록 삽입한 후, 고주파발생기(미도시)로부터 고주파를 통전부(6a)에 공급하여, 통전부(6a)로부터 발생되는 고주파 열에 의해, 병변부위를 소작하여 괴사시키는 치료를 하게 되는 것이다.Then, the operator inserts the electrode needle 6 so as to penetrate the lesion site such as cancer tissue of the body organ, and then supplies a high frequency from the high frequency generator (not shown) to the energizing portion 6a, and from the energizing portion 6a. Due to the high frequency heat generated, the treatment of the lesion site by necrosis is performed.
이때, 환자의 몸(외측 피부)에 접지패드를 부착하는데, 이 접지패드도 고주파발생기에 전기적으로 연결된다.At this time, a ground pad is attached to the patient's body (outside skin), which is also electrically connected to the high frequency generator.
따라서, 고주파발생기에 전원을 인가하면 전극침으로부터 접지패드 쪽으로 전류의 전달경로가 형성되며, 이 전달과정에서 이온의 진동에 의한 마찰에너지가 조직의 온도를 상승시켜, 병변부위 조직의 응고 및 괴사를 유도하게 되는 것이다.Therefore, when power is supplied to the high frequency generator, a path of current flows from the electrode needle to the ground pad. In this process, friction energy caused by the vibration of ions raises the temperature of the tissue, thereby solidifying and necrosis of the lesion tissue. It will be induced.
그런데, 전술한 바와 같은 구성의 전극침을 사용하여 시술하는 경우, 접지패드가 환자의 피부에 부착됨에 따라, 고주파 전류가 병변부위에만 국부적으로 작용하지 못하고, 가이드침으로부터 접지패드까지의 경로에 작용하게 되어, 정상 기관 및 조직에 영향을 미치게 되거나, 접지패드 부착부위에 화상을 입게 되는 문제가 있다.However, when the procedure is performed using the electrode needle of the above-described configuration, as the ground pad is attached to the skin of the patient, the high frequency current does not act locally only on the lesion site, but acts on the path from the guide needle to the ground pad. As a result, there is a problem that affects normal organs and tissues, or burns the ground pad attachment site.

이때, 적어도 둘 이상의 통전부는 각각 액티브 전극 또는 그라운드 전극으로 이루어진다.In this case, at least two conductive parts each include an active electrode or a ground electrode.
또한, 적어도 둘 이상의 통전부 중 적어도 어느 하나는 외주면 일측에 부분적으로 구비될 수 있다.In addition, at least one of the at least two conductive parts may be partially provided on one side of the outer circumferential surface.
또한, 적어도 둘 이상의 통전부 중 적어도 한 쌍이 외주면 일측에 부분적으로 구비될 수 있으며, 이때 길이방향으로 이격하여 서로 엇갈리게 배치될 수 있다.In addition, at least one pair of at least two conductive parts may be partially provided on one side of the outer circumferential surface, and in this case, they may be spaced apart from each other in the longitudinal direction.
이때, 외주면 일측에 부분적으로 구비되는 통전부의 길이방향으로 인접하는 절연부는, 서로 연결되어 일체로 형성되는 것이 바람직하다.At this time, it is preferable that the insulating portions adjacent to each other in the longitudinal direction of the current conducting portion partially provided on one side of the outer circumferential surface are integrally formed with each other.

도 2 내지 도 10에 도시된 바와 같이, 본 발명의 실시예에 따른 고주파 열치료용 비대칭 바이폴라 전극침(이하, '전극침')은, 병변부위의 조직에 삽입된 상태로 고주파를 방사하여, 주변의 조직을 응고시켜 괴사시키는 것이다.As shown in Figure 2 to 10, the asymmetric bipolar electrode needle (hereinafter referred to as "electrode needle") for high frequency thermal therapy according to an embodiment of the present invention, by radiating high frequency in the state inserted into the tissue of the lesion site, The surrounding tissues are coagulated and necrotic.
이때, 전극침에는 적어도 둘 이상의 통전부(20)가 구비되며, 고주파발생기(미도시)에 각각 전기적으로 연결되어, 액티브(active) 전극 또는 그라운드(ground) 전극으로 기능하게 된다.At this time, the electrode needle is provided with at least two conductive parts 20, each electrically connected to a high frequency generator (not shown), and functions as an active electrode or a ground electrode.
따라서, 종래와 같이 별도의 접지패드를 필요로 하지 않는다.Therefore, a separate ground pad is not required as in the prior art.
또한, 본 발명의 실시예에 따른 전극침은, 예를 들어 스테인레스 스틸 등 인체에 무해하고 녹이 슬지 않으며 통전 가능한 금속재질의 관으로 이루어지는데, 병변부위의 조직에 삽입되는 선단부 소정 구간을 제외한 나머지 부분은 테프론 등의 절연재에 의해 피복부(40)가 형성되는 것이 바람직하다.In addition, the electrode needle according to an embodiment of the present invention, for example, stainless steel is harmless to the human body, rust free and made of a conductive metal tube, the remaining portion except for a predetermined section of the tip portion inserted into the tissue of the lesion site It is preferable that the coating part 40 is formed of insulating materials, such as silver Teflon.
이때, 본 발명의 실시예에 따른 전극침은, 적어도 하나 이상의 절연부(30)와, 절연부(30)에 의해 서로 이격되는 적어도 둘 이상의 통전부(20)를 포함하여 이루어질 수 있으며, 예를 들어 전극침의 피복부(40)를 제외한 선단부 소정 구간이 통전부(20)를 이루고, 통전부(20)의 외주면에 테프론이나 용융된 합성수지 등의 절연재가 원주방향으로 피복되어 절연부(30)를 이룰 수 있다.In this case, the electrode needle according to the embodiment of the present invention may include at least one or more insulating portions 30 and at least two conductive portions 20 spaced apart from each other by the insulating portion 30. For example, a predetermined portion of the tip portion excluding the electrode portion covering portion 40 constitutes the conductive portion 20, and an insulating material such as Teflon or molten synthetic resin is coated in the circumferential direction on the outer circumferential surface of the conductive portion 20, so that the insulating portion 30 is formed. Can be achieved.
한편, 통전부(20)의 일측에 링 형상의 절연재가 결합하여 절연부(30)를 이루는 것도 가능한데 이때, 전극침의 외주면에 단차가 생기지 않도록, 통전부(20)의 일측에 결합홈(미도시)을 형성하고, 이 결합홈에 링 형상의 절연부(30)를 결합하여, 절연부(30)의 외경과 전극침의 외경이 일치되도록 하는 것이 바람직하다.On the other hand, it is also possible to form an insulating portion 30 by coupling a ring-shaped insulating material to one side of the energizing portion 20, at this time, the coupling groove (not shown) on one side of the energizing portion 20 so that a step does not occur on the outer peripheral surface of the electrode needle C) and a ring-shaped insulating portion 30 is coupled to the coupling groove so that the outer diameter of the insulating portion 30 and the outer diameter of the electrode needle coincide with each other.
이때, 절연부(30)와 통전부(20)의 개수 및 길이 등 규격은 필요에 따라 적절히 선택될 수 있다.In this case, the size and the like of the insulation portion 30 and the current conduction portion 20 may be appropriately selected as necessary.
도 2는 본 발명의 일실시예에 따른 고주파 열치료용 비대칭 바이폴라 전극침의 구성도이고, 도 3은 한 쌍의 통전부가 절연부에 대하여 대칭으로 형성되었을 때(a)와 비대칭으로 형성되었을 때(b)의 소작 형태를 비교한 일 예이다.2 is a block diagram of an asymmetric bipolar electrode needle for high frequency heat treatment according to an embodiment of the present invention, Figure 3 is a pair of current-carrying parts are formed symmetrically with respect to the insulating portion (a) and when formed asymmetrically It is an example of comparing the cauterization form of (b).
본 발명의 일실시예에 의하면, 도 2에 도시된 바와 같이 하나의 절연부(30)를 사이에 두고 한 쌍의 통전부(20)가 서로 이격하여 형성되며, 전극침(11)의 내부에서 각각의 통전부(20)에 연결되는 전극라인(4, 도 1 참조)이 고주파발생기(미도시)에 각각 접속된다.According to one embodiment of the present invention, as shown in FIG. 2, a pair of energizing parts 20 are formed to be spaced apart from each other with one insulating part 30 interposed therebetween. Electrode lines 4 (refer to FIG. 1) connected to the respective energization portions 20 are respectively connected to a high frequency generator (not shown).
이때, 절연부(30)를 사이에 두고 한 쌍의 통전부(20)는 서로 길이가 다른 비대칭 구조로 형성되며 따라서, 한 쌍의 통전부(20)의 표면적 비율이 상이하다.At this time, the pair of energizing parts 20 with the insulating part 30 therebetween is formed in an asymmetrical structure having a different length from each other, so that the ratio of the surface area of the pair of energizing parts 20 is different.
이처럼 통전부(20)의 표면적 비율이 상이한 경우, 표면적이 상대적으로 작은 통전부(20)에 전류가 집중되어, 표면적이 상대적으로 큰 통전부(20) 보다 열이 빨리 발생하고, 소작이 먼저 이루어진다.When the ratio of the surface area of the energizing portion 20 is different in this way, current is concentrated in the energizing portion 20 having a relatively small surface area, so that heat is generated faster than the energizing portion 20 having a relatively large surface area, and cauterization is performed first. .
즉, 도 3(a)에 도시된 바와 같이, 절연부(30)에 대하여 한 쌍의 통전부(20)가 대칭으로 형성된 경우에는, 절연부(30)와 인접하는 통전부(20) 부분에서 소작이 시작되어 한 쌍의 통전부(20) 사이에 전체적으로 소작이 이루어지며, 도 3(b)에 도시된 바와 같이, 절연부(30)에 대하여 한 쌍의 통전부(20)가 비대칭으로 형성된 경우, 소작의 형태는 표면적이 상대적으로 작은 통전부(20) 쪽으로 치우치는 소작 형태를 이루게 된다.That is, as shown in FIG. 3A, when the pair of energizing parts 20 are formed symmetrically with respect to the insulating part 30, the portion of the energizing part 20 adjacent to the insulating part 30 is formed. Cauterization is initiated and cauterization is generally performed between the pair of energizing parts 20. As shown in FIG. 3 (b), a pair of energizing parts 20 are asymmetrically formed with respect to the insulating part 30. FIG. In this case, the cautery form is a cautery form biased toward the conducting portion 20 having a relatively small surface area.
따라서, 통전부(20)가 비대칭으로 형성된 경우, 대칭으로 형성된 경우에 비해 소작되는 크기는 작지만 소작속도는 더 빠르게 진행되며, 큰 병소를 반복하여 여러 번 소작해야 할 때, 통전부(20)가 비대칭인 경우에 보다 정밀하고 빠르게 소작할 수 있게 되는 것이다.Therefore, when the current-carrying part 20 is formed asymmetrically, the size of cauterization is smaller than that of the case of symmetrical formation, but the cauterization speed is faster, when the cauterization part 20 needs to be cauterized repeatedly several times, In the case of asymmetry, it is possible to cauterize more precisely and quickly.
이때, 통전부(20)의 표면적 비율을 조절함으로써, 전극침 주변의 병변부위 조직이 소작되는 형태를 선택할 수 있는데, 이에 대하여는 도 4를 참고하여 아래에서 설명하기로 한다.At this time, by adjusting the surface area ratio of the energization portion 20, it is possible to select a form in which the lesion tissue surrounding the electrode needle cauterized, which will be described below with reference to FIG.
도 4는 본 발명의 일실시예에 따라, 통전부의 표면적 비율에 따른 소작 형태를 도시한 개략도이다.Figure 4 is a schematic diagram showing a cauterized form according to the surface area ratio of the energizing portion, according to an embodiment of the present invention.
도 4(a)에 도시된 바와 같이, 전극침의 선단으로부터 절연부(30)를 사이에 둔 한 쌍의 통전부(20)의 표면적 비율이 거의 유사하여 대칭을 이루는 경우, 한 쌍의 통전부(20) 사이에서 전체적으로 소작이 이루어지며, 도 4(b)와 도 4(c)에 도시된 바와 같이, 통전부(20)의 표면적 비율이 서로 상이하여 비대칭을 이루는 경우에는, 표면적이 상대적으로 작은 통전부(20)에 치우쳐서 소작이 이루어진다.As shown in Fig. 4 (a), when the ratio of the surface area of the pair of energizing parts 20 with the insulating part 30 interposed from the tip of the electrode needle is almost similar, the pair of energizing parts is symmetrical. Cauterization is entirely performed between the 20, and as shown in Fig. 4 (b) and 4 (c), when the ratio of the surface area of the energizing portion 20 is different from each other and asymmetric, the surface area is relatively The cauterization is made by biasing the small energization part 20.
즉, 한 쌍의 통전부(20)의 표면적 비율을 적절히 선택함으로써, 도 4(b)에 도시된 바와 같이 전극침의 상단 통전부(20)를 중심으로 소작이 이루어지게 하거나, 도 4(c)에 도시된 바와 같이 전극침의 하단 통전부(20)를 중심으로 소작이 이루어지게 하는 등, 소작 범위와 형태, 속도 등을 조절할 수 있게 되는 것이다.That is, by appropriately selecting the ratio of the surface area of the pair of energizing portions 20, as shown in FIG. 4 (b), cauterization is performed around the upper energizing portion 20 of the electrode needle, or FIG. 4 (c). As shown in Figure 6, such as cauterization to be made around the bottom conducting portion 20 of the electrode needle, it is possible to adjust the cauterization range and shape, speed and the like.
이때, 전극침의 피복부(40)를 제외한 선단부 소정 구간을 통전부(20)로 형성하고, 이 통전부(20)의 일측에 링 형상의 절연부(30)를 슬라이드 이동 가능하게 결합하는 경우, 필요에 따라 전극침의 길이방향으로 절연부(30)를 적절히 이동시킴으로써, 절연부(30)에 의해 구획되는 한 쌍의 통전부(20)의 표면적 비율을 변화시킬 수 있으며, 따라서 소작 범위와 형태, 속도 등을 간편하게 조절할 수 있게 된다.At this time, when the predetermined portion of the tip portion excluding the covering portion 40 of the electrode needle is formed as the conducting portion 20, and the ring-shaped insulating portion 30 is coupled to one side of the conducting portion 20 so as to be slidable. By appropriately moving the insulating portion 30 in the longitudinal direction of the electrode needle as necessary, the ratio of the surface area of the pair of energizing portions 20 partitioned by the insulating portion 30 can be changed, and thus the cauterization range and Shape, speed, etc. can be easily adjusted.
도 5는 본 발명의 다른 실시예에 따른 고주파 열치료용 비대칭 바이폴라 전극침의 구성도이고, 도 6은 본 발명의 다른 실시예에 따른 병변부위 소작 예시도이다.5 is a block diagram of the asymmetric bipolar electrode needle for high frequency heat treatment according to another embodiment of the present invention, Figure 6 is a schematic view of the lesion site cauterization according to another embodiment of the present invention.
본 발명의 다른 실시예에 따른 전극침(12)의 경우, 도 5에 도시된 바와 같이 서로 이격하는 두 개의 절연부(30)에 의해 세 개의 통전부(20)가 이격하여 형성될 수 있으며, 이때 세 개의 통전부(20) 중 어느 하나는 액티브 전극으로 형성되고, 다른 하나는 그라운드 전극으로 형성되며, 나머지 하나는 액티브 전극과 그라운드 전극 중 어느 하나로 선택될 수 있다.In the electrode needle 12 according to another embodiment of the present invention, as shown in FIG. 5, three conductive parts 20 may be formed by two insulating parts 30 spaced apart from each other. At this time, any one of the three conductive parts 20 may be formed as an active electrode, the other may be formed as a ground electrode, and the other may be selected as one of an active electrode and a ground electrode.
이때, 하나의 절연부(30)를 사이에 두고 서로 인접하는 한 쌍의 통전부(20)는 길이가 서로 다르게 비대칭으로 형성되며, 이처럼 통전부(20)의 개수를 늘리는 경우, 더욱 넓은 범위로 소작이 가능하다.At this time, the pair of conductive parts 20 adjacent to each other with one insulating part 30 therebetween is formed asymmetrically different in length, and thus, when the number of the conductive parts 20 is increased, a wider range Cauterization is possible.
즉, 액티브 전극인 통전부(20)와, 그라운드 전극인 통전부(20) 사이의 이격거리가 너무 먼 경우, 고주파 전류의 전파가 원활하지 못하여 효과적인 소작이 곤란한데, 통전부(20)의 개수를 늘림으로써, 도 6에 도시된 바와 같이 소작 범위가 중첩되게 하여, 결과적으로 소작 범위를 확대시킬 수 있게 되는 것이다.That is, when the separation distance between the energizing part 20 which is an active electrode and the energizing part 20 which is a ground electrode is too far, it is difficult to carry out effective cauterization because the propagation of a high frequency current is not smooth, but the number of the energizing parts 20 By increasing, the cauterization range is overlapped as shown in FIG. 6, and as a result, the cauterization range can be enlarged.
이때, 예를 들어 상하 양측에 위치하는 통전부(20)는 액티브 전극이 되고 가운데에 위치하는 통전부(20)는 그라운드 전극이 된다.At this time, for example, the conducting portions 20 located on both the upper and lower sides become active electrodes, and the conducting portions 20 positioned in the center become ground electrodes.
아울러, 통전부(20)의 표면적 비율을 서로 다르게 함으로써 소작의 방향과 속도를 제어할 수 있음은 전술한 바와 같다. In addition, it is as described above that the direction and speed of cauterization can be controlled by varying the surface area ratio of the energization part 20.
도 7은 본 발명의 다른 실시예에 따라 소작 범위가 조절되는 예를 도시한 병변부위 소작 예시도이다.Figure 7 is an exemplary view of the lesion site cauterization showing an example in which the cauterization range is adjusted according to another embodiment of the present invention.
본 발명의 실시예에 따른 전극침은 각각의 통전부(20)에 전달되는 고주파 전류를 선택적으로 차단하거나 해제함으로써, 소작 범위를 조절할 수 있다.The electrode needle according to the embodiment of the present invention may control the cauterization range by selectively blocking or releasing the high frequency current transmitted to each conducting unit 20.
예를 들어, 도 5에 도시된 본 발명의 다른 실시예에 따른 전극침(12)의 경우, 도 7(a)에 도시된 바와 같이, 최상단의 통전부(20)에 액티브 전극을 연결하고, 가운데의 통전부(20)에는 그라운드 전극을 연결하며, 최하단의 통전부(20)에 전달되는 고주파전류를 차단함으로써, 전극침(12)의 상단부 주변이 소작되도록 할 수 있다.For example, in the case of the electrode needle 12 according to another embodiment of the present invention shown in FIG. 5, as shown in FIG. 7 (a), the active electrode is connected to the uppermost conducting portion 20. The ground electrode is connected to the central conducting portion 20, and the high frequency current transmitted to the lowermost conducting portion 20 can be interrupted to allow cauterization of the periphery of the upper end of the electrode needle 12.
마찬가지로, 도 7(b)에 도시된 바와 같이, 최하단의 통전부(20)에 액티브 전극을 연결하고, 가운데의 통전부(20)에는 그라운드 전극을 연결하며, 최상단의 통전부(20)에 전달되는 고주파전류를 차단함으로써, 전극침(12)의 하단부 주변이 소작되도록 할 수 있다. Similarly, as shown in FIG. 7B, the active electrode is connected to the lowermost energizing part 20, the ground electrode is connected to the central energizing part 20, and is transferred to the uppermost energizing part 20. By cutting off the high frequency current, the periphery of the lower end of the electrode needle 12 can be cauterized.
즉, 각각의 통전부(20)에 전달되는 고주파 전류를 선택적으로 차단하거나 해제함으로써, 필요에 따라 전극침(12)의 상하 방향으로 소작 범위를 이동시킬 수 있게 되는 것이다.That is, by selectively blocking or releasing the high frequency current transmitted to each energizing unit 20, the cauterization range can be moved in the vertical direction of the electrode needle 12 as necessary.
이때, 최상단과 가운데 및 최하단의 통전부(20) 각각에 모두 전극을 연결하는 경우, 도 6에 도시된 바와 같이 최상단의 통전부(20)와 최하단의 통전부(20) 사이에 소작이 이루어지도록 할 수 있으며, 이에 따라 소작되는 속도와 소작 범위가 증가함은 전술한 바와 같다.At this time, when the electrode is connected to each of the top and the middle and the bottom of the conductive portion 20, as shown in Figure 6 so that cauterization is made between the top of the conductive portion 20 and the bottom of the conductive portion 20 As a result, the rate of cauterization and the range of cauterization are increased as described above.
한편, 도 5 내지 도 7에 도시된 실시예에서는 통전부(20)의 길이비가 1:2:1인 예를 도시하였으나, 반드시 여기에 한정되는 것은 아니며, 예를 들어 1:4:2의 길이비에 의해서도 전술한 바와 같은 효과를 얻을 수 있다.On the other hand, in the embodiment shown in Figures 5 to 7 has shown an example in which the length ratio of the energizing portion 20 is 1: 2: 1, but is not necessarily limited to this, for example, the length of 1: 4: 2: By the ratio, the same effects as described above can be obtained.
도 8 내지 도 10은 본 발명의 각각 또 다른 실시예에 따른 고주파 열치료용 비대칭 바이폴라 전극침의 구성도이다.8 to 10 are configuration diagrams of the asymmetric bipolar electrode needle for high frequency heat treatment according to another embodiment of the present invention.
때에 따라서는, 소작시키고자 하는 병변부위에 병변과 무관한 정상 장기나 혈관, 신경 등이 근접해 있는 경우가 있으며 이때, 지금까지 설명한 실시예에서와 같이, 통전부(20)를 중심으로 전극침의 주위 360°방향 전체를 소작하는 경우, 병변과 무관한 장기, 혈관, 신경 등이 훼손될 우려가 있다.Occasionally, normal organs, blood vessels, and nerves, which are not related to the lesion, may be close to the lesion to be cauterized. In this case, as in the above-described embodiment, the electrode needle is centered on the conducting unit 20. When cauterizing the entire 360 ° direction, organs, blood vessels, nerves, and the like that are not associated with lesions may be damaged.
이를 방지하기 위해, 전극침을 중심으로 소정 각도 범위의 병변부위만이 소작되도록 해야 할 필요가 있으며, 도 8 내지 도 10은 이에 따른 실시예를 도시하고 있다.In order to prevent this, it is necessary to ensure that only the lesion area of the predetermined angle range centers on the electrode needle, and FIGS. 8 to 10 show an embodiment accordingly.
도 8에 도시된 바와 같이, 적어도 하나의 통전부(20)가 전극침(13)의 외주면 일측에 소정 각도 범위만큼 부분적으로 구비될 수 있으며, 이 통전부(20)의 길이방향으로 인접하는 절연부(30)는 서로 연결되어 일체로 형성된다.As shown in FIG. 8, at least one conduction portion 20 may be partially provided on one side of the outer circumferential surface of the electrode needle 13 by a predetermined angle range, and the insulation adjacent to the length direction of the conduction portion 20 may be provided. The part 30 is connected to each other and integrally formed.
즉, 부분적으로 구비되는 통전부(20)의 상하측에 각각 형성되는 절연부(30)가, 통전부(20)의 반경방향 반대쪽에서 서로 연결되어, 통전부(20)의 둘레를 따라 형성되는 절연부(30)에 의해 통전부(20)가 감싸지게 되는 것이다.That is, the insulating portions 30 respectively formed on the upper and lower sides of the portion of the conductive portion 20, which is provided in part, are connected to each other on the opposite side in the radial direction of the conductive portion 20, and are formed along the circumference of the conductive portion 20. The conductive part 20 is wrapped by the insulating part 30.
한편, 본 발명의 또 다른 실시예로서, 도 9에 도시된 바와 같이 두 개 이상의 통전부(20)가 전극침(14)의 외주면 일측에 소정 각도 범위만큼 부분적으로 서로 이격하여 구비되는 것도 가능하며 이때, 부분적으로 구비되는 통전부(20)의 개수와 폭 및 길이 등의 규격은 필요에 따라 적절히 선택될 수 있다.Meanwhile, as another embodiment of the present invention, as shown in FIG. 9, two or more energizing parts 20 may be provided to be partially spaced apart from each other by a predetermined angle range on one side of the outer circumferential surface of the electrode needle 14. At this time, the number, width and length of the portion of the conducting portion 20 provided in part may be appropriately selected as necessary.
또한, 도 10에 도시된 바와 같이, 본 발명의 또 다른 실시예로서, 상하 이격하여 부분적으로 구비되는 한 쌍의 통전부(20)가 전극침(15)의 길이방향으로 서로 엇갈리게 배치되도록 할 수도 있다.In addition, as shown in FIG. 10, as another embodiment of the present invention, a pair of energizing parts 20 which are partially spaced apart from each other in the vertical direction may be alternately arranged in the longitudinal direction of the electrode needle 15. have.
이 경우, 전극침(15)의 축방향에 대해 소정 각도 기울어진 방향으로 소작 범위를 형성시킬 수 있으며, 따라서 전극침(15)의 삽입방향에 대하여 소정 각도 기울어진 방향으로 형성된 병변부위를 용이하게 소작시킬 수 있게 된다.In this case, the cauterization range can be formed in a direction inclined at a predetermined angle with respect to the axial direction of the electrode needle 15, and thus, a lesion site formed in a direction inclined at a predetermined angle with respect to the insertion direction of the electrode needle 15 can be easily formed. You can cauterize.
