To provide a trocar housing to provide a mechanism simple and reliable for connecting the housing member and the second housing member SOLVED] first. Trocar housing SOLUTION: A trocar assembly for includes a first housing member which is selectively connected to the second housing member. Housing member and the second housing member of the first, includes a hole that is aligned. These holes are shaped and dimensioned such instrument extending therethrough. Button latch mechanism, to be selectively coupled to the housing member and the second housing member of the first. Includes a latch member which slides around the central axis the housing member and the second housing member of claim 1, whereby said button latch mechanism, selecting the housing member and the second housing member of the first I be linked to specific. [Selection] Figure Figure 1【課題】第1のハウジング部材および第2のハウジング部材を接続するための簡便かつ信頼性の高い機構を提供するトロカールハウジングを提供する。【解決手段】トロカール組立体用のトロカールハウジングは、第2のハウジング部材に選択的に連結された第1のハウジング部材を含む。前記第1のハウジング部材および前記第2のハウジング部材は、整合された孔を含む。これらの孔は、内部を器具が貫通するような形状および寸法にされる。ボタンラッチ機構は、前記第1のハウジング部材および前記第2のハウジング部材を選択的に連結させる。前記ボタンラッチ機構は、前記第1のハウジング部材および前記第2のハウジング部材を中央軸の周囲でスライドするラッチ部材を含み、これにより、前記第1のハウジング部材および前記第2のハウジング部材を選択的に連結させる。【選択図】図1
