    • A medical instrument serves for creating an access for a minimally invasive intervention and has a body having a longitudinal axis. The body is assembled of at least two parts, each of said parts having edges extending along a direction of said axis. Each of said parts having edges extending along a direction of said axis. Each part has a distal section merging into a proximal section standing outwardly from said longitudinal axis. In a first position, the distal end section of the parts are joined along said edges to form a distal body with the proximal section standing away. In a second position, the proximal sections of said parts are joined along said edges to form a hollow proximal body with said distal end section spreaded outwardly. The edges are provided with interacting features which are designed to block a lateral sliding of said joined parts transversely to said edges.
    • 医疗器械用于创建微创介入的通路,并具有具有纵向轴线的主体。 身体由至少两部分组装,每个所述部分具有沿所述轴线的方向延伸的边缘。 每个所述部件具有沿着所述轴线的方向延伸的边缘。 每个部分具有汇合到从所述纵向轴线向外站立的近侧部分的远侧部分。 在第一位置,部件的远端部分沿着所述边缘接合以形成远端本体,其中近侧部分搁置。 在第二位置,所述部件的近端部分沿着所述边缘连接以形成中空的近端体,所述远端部分向外扩展。 边缘设置有相互作用的特征,其被设计成阻挡所述接合部分横向于所述边缘的横向滑动。
