PROBLEM TO BE SOLVED: To provide a controllable electrode for electrosurgery that is suitable for low-invasive surgery and has increased stiffness.SOLUTION: A controllable electrode for electrosurgery includes a handle 10, a control member 20, a first tube body 30, a second tube body 40, a third tube body 50, an electrode 60, and a transmission unit 70. The handle has a flat section. The control member has multiple positioning planes and is axially attached to the handle so that any one of the positioning planes directly contacts the flat section in a rotatable manner. The first tube body is arranged within the second tube body and is axially attached to the control member. The third tube body is connected to the second tube body and the first tube body through a first link 82 and a second link 84, respectively. The electrode is placed at a right end of the third tube body. A user operates the control member so as to make direct contact with the flat section on a different positioning plane, moves the first tube body within the second tube body and then rotates the third tube body and the electrode.SELECTED DRAWING: Figure 2【課題】低侵襲性手術に適し、剛性がより優れた、操縦可能な電気手術用電極を提供する。【解決手段】操縦可能な電気手術用電極は、ハンドル１０と、制御部材２０と、第１管体３０と、第２管体４０と、第３管体５０と、電極６０と、送電ユニット７０を含み、前記ハンドルが平坦区域を備え、前記制御部材が複数の位置決め平面を備え、かつ前記位置決め平面のいずれかが前記平坦区域に回動可能に当接されるように前記ハンドルに軸着され、前記第１管体が前記第２管体内部に配置され、かつ前記制御部材に軸着され、前記第３管体が第１リンク８２と第２リンク８４をそれぞれ介して前記第２管体と前記第１管体に連結され、前記電極が前記第３管体の右端部に設置され、使用者は前記制御部材を異なる位置決め平面で前記平坦区域に当接するように操作して、前記第２管体内部の第１管体を動かし、さらに前記第３管体と前記電極を回動させる。【選択図】図２
