Trocar system
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】本発明は、トロッカー内針で形成された小径な 穿刺孔の径を外套管の外径寸法まで拡開させる作業時に 腹腔内の臓器などを強く押圧するおそれがないうえ、外 套管を体壁に挿入、留置する作業を簡単に、短時間で行 うことができるトロッカーシステムを提供することを最 も主要な特徴とする。 【解決手段】外套管7とトロッカー内針6との間に介挿 されたダイレータ8の先端部から外部側に柔軟な筒状部 材のガイド部材9の先端部を突出させた状態で、ガイド 部材9の取手部29を手指で掴み、ダイレータ8に対し てガイド部材9の取手部29を軸方向に引っ張ることに より、ダイレータ8の先端部から外部側に突出されるガ イド部材9の先端部の突出量を調整するものである。 (57) Abstract: The present invention has a risk of strongly pressing an organ or the like in the abdominal cavity at the time of expanding the diameter of a small puncture hole formed by a trocar inner needle to the outer diameter of a mantle tube. In addition, the most important feature of the present invention is to provide a trocar system that can easily and quickly insert and detain a mantle tube into a body wall. A guide member is provided in a state in which a distal end of a flexible tubular member is projected outward from a distal end of a dilator inserted between a mantle tube and a trocar inner needle. The handle portion 29 of the guide member 9 is gripped by a finger and the handle portion 29 of the guide member 9 is pulled in the axial direction with respect to the dilator 8, so that the tip portion of the guide member 9 protrudes outward from the tip portion of the dilator 8. Adjust the amount.
