Zusammenfassung:To provide an electrosurgical instrument with two branches pivotably supported at each other that guarantees a simplified cleaning and/or sterilization.SOLUTION: The invention relates to an electrosurgical instrument (10) with two branches (11, 12) that are pivotably supported at each other by means of a pivot joint (13). The pivot joint (13) has a support pin (34) and a support cavity (37). The support pin (34) is particularly torque-proof connected with one of the branches (11) or (12) and rotatably supported in the support cavity (37) of the other branch (12) or (11). Between the branches (11, 12), a seal (45) is provided that hermetically abuts at the two branches (11, 12) and that surrounds the support pin (34) completely in a circumferential direction. Preferably, the support pin (34) is hermetically connected with the respective branches (11, 12) at its axial ends.SELECTED DRAWING: Figure 4 【課題】簡易なクリーニングおよび/または滅菌を保証する、互いにピボット支持された2つの分枝体を有する電気手術器具を提供する。【解決手段】本発明は、ピボットジョイント(13)を用いて互いにピボット支持される2つの分枝体(11、12)を有する電気手術器具(10)に関する。ピボットジョイント(13)は、支持ピン(34)と支持穴(37)とを有する。支持ピン(34)は、特に、一方の分枝体(11)または(12)にトルクに耐えられるように接続され、それぞれ他方の分枝体(12)または(11)の支持穴(37)内で回転可能に支持される。分枝体(11、12)の間には、2つの分枝体(11、12)に密封当接し、円周方向で支持ピン(34)を完全に囲むシール(45)が設けられる。支持ピン(34)は、軸端で分枝体それぞれ(11、12)に密封接続されるのが好ましい。【選択図】図4
