PROBLEM TO BE SOLVED: To provide an insertion instrument for medical treatment instruments which is provided with several ports for applying several treatment instruments to one incisional wound and can easily and effectively arrange a multitude of ports the occupied area of each of which is downsized without deteriorating their airtightness.SOLUTION: The insertion instrument for medical treatment instruments comprises an elastic member. It is formed as a cap member 4 which is provided with several concaves 41 as ports for medical treatment instruments or the like being inclined with their diameters reduced from their surfaces toward their bottoms, being in the shape of a mortar or a ball, for example, or being like a sine curve in cross-section and is arranged on the body surface side of an incising means. The concaves 41 are preferably continuous concavities and convexities on the whole surface of the cap member 4, have several diameters and are formed without previously arranging an opening into a body cavity. The cap member 4 is formed so that it can be attached to and detached from the incising means.COPYRIGHT: (C)2012,JPO&INPIT【課題】ひとつの切開創に複数の処置器具を適用するため、複数のポートを備える挿入器具において、ひとつひとつの占有面積を小さくしたポートを、気密性を損なうことなく、容易、かつ、有効に多数配置できる医療用処置具の挿入器具を提供すること。【解決手段】本発明の医療用処置具の挿入器具は、弾性部材よりなり、医療用処置具等のポート部として、表面部から底部に向って径を縮小して傾斜する、例えば、すり鉢状、ボール状、あるいは、断面をサイン曲線に類する形状とした複数の窪み41を備えた、開創手段の体表側に配置するキャップ部材4として形成され、好ましくは、前記窪み41は、キャップ部材4表面全体に連続した凹凸形状であり、複数の径を備え、体腔内への予めの開口孔を設けないものとして形成し、前記キャップ部材4は、前記開創手段と着脱可能に形成して構成した。【選択図】 図1
