Problem to be solved: to test the insulation in the same environment as the actual operation, and to detect the minute result without the fluctuation in the inspection result by the inspecting person, to be able to detect the minute scratch, and to have the accuracy and reproducibility, and to inspect the forceps for endoscope operation which can improve the inspection efficiency, inspection container, and inspection device. Provide.Used in endoscopic surgeryIn a forceps having an insulating structure in which an outer peripheral portion of a metal cylindrical body 5 is covered with an insulatorAn inspection method for inspecting the insulation of the insulating structure；The forceps are inserted into the inspection container 11 in which the conductive liquid 12 is held inside.The part of the insulator 6 in the forceps is housed in the inspection vesselThe step of fixing at least a part of the metal tubular body 5 from the end of the inspection vessel 11 in a state of projecting from the end portion of the inspection vesselA voltage is applied between the metal cylindrical body 5 and the conductive liquidMetal tubular bodyA step of measuring an insulation resistance value between the insulator 6 and the insulator 6 contacting the conductive liquid 12.Diagram【課題】実際の手術と同様の環境下での絶縁性の検査が可能であり、検査実施者によって検査結果にバラツキがなく、微小な傷の検知ができ、正確性と再現性を兼ね備え、さらに検査効率の向上が図れる内視鏡手術用鉗子の検査方法、検査容器、および検査装置を提供する。【解決手段】内視鏡手術で使用される、金属筒状体５の外周部を絶縁体６で被覆した絶縁構造を有する鉗子において、その絶縁構造の絶縁性を検査する検査方法であり、導電性液体１２が内部に保持された検査容器１１に鉗子を挿入して、鉗子における絶縁体６に係る部分を検査容器１１の内部に収容しつつ、金属筒状体５の少なくとも一部を検査容器１１の端部から突出した状態で固定する工程と、金属筒状体５と導電性液体１２との間に電圧を印加し、金属筒状体５と、導電性液体１２に接触している絶縁体６との間の絶縁抵抗値を測定する工程とを有する。【選択図】図４
