PROBLEM TO BE SOLVED: To provide a forceps plug configured to reliably prevent humor from leaking to the outside of a body via a forceps port regardless of an operation state of a treatment instrument inserted into a treatment instrument passage via the forceps port, and an endoscope apparatus.SOLUTION: The forceps plug includes: a partition part 51s located adjacent to a forceps port 20b when being attached to a forceps ferrule 30 and having a hole 51h, the periphery of which is formed of a soft material and a guide 55 that, when a treatment instrument is inserted into the forceps port 20b via the hole 51h, positions the treatment instrument so as to be inserted along a center of the hole 51h, and has a portion having higher rigidity than that of the partition part 51s, formed at least at a part thereof.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】鉗子口を介して処置具挿通路に挿入された処置具の操作状態によらず、鉗子口を介して体液が体外に漏れてしまうことをより確実に防止することができる構成を具備する鉗子栓、内視鏡装置を提供する。【解決手段】鉗子口金30に取り付けられた際に鉗子口20bに隣接して位置するとともに、周囲が柔軟な材質で形成された孔51hを有する仕切り部51sと、孔51hを介して処置具が鉗子口20bに挿入される際、孔51hの中心に沿うように処置具を位置決めする、仕切り部51sよりも高い剛性の部位を少なくとも一部に有するガイド55と、を具備する。【選択図】図2
