摘要： A surgical access device comprises an elongate shaft with a bladeless tip at the distal end. The bladeless tip has an outer surface with a proximal portion, a distal portion, and an intermediate portion. In a cross section in the proximal portion, the outer surface defines a circle. In a cross section in the intermediate portion, the outer surface defines a shape having a length greater than a width. The outer surface has first and second opposing surface portions of the shape that are generally aligned with the length. In a cross section in the distal portion, the outer surface defines a circle. In progressive proximal cross sections in the distal portion, the circle expands. In progressive proximal cross sections in the intermediate portion, a ratio of the width of the shape to the length of the shape increases and the first and second opposing surface portions are more arcuate.

摘要： A surgical obturator comprising an elongate shaft extending along an axis between a proximal end and a distal end, and a bladeless tip disposed at the distal end of the shaft having a conical surface forming proximally into an outer surface, the outer surface extending distally to a blunt point and having a pair of side sections. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. The conical surface facilitates insertion of the obturator with a reduced penetration force and minimizes tenting of the body wall. The conical surface further facilitates separation of different layers of the body wall and provides proper alignment of the tip between the layers. The surgical obturator may be constructed from a disposable or reusable material such as a metal or an autoclavable polymer. While certain embodiments have been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope thereof as defined by the following claims.

摘要翻译： 一种手术闭塞器，包括沿着近端和远端之间的轴线延伸的细长轴，以及设置在所述轴的远端处的无叶尖，其具有向近侧形成外表面的锥形表面，所述外表面向远侧延伸至 钝点并具有一对侧面部分。 侧面部分从钝点径向向外延伸，并沿着轴线向近端延伸。 锥形表面有助于以更小的穿透力插入封闭器并最小化身体壁的隆起。 锥形表面进一步有利于分离体壁的不同层，并提供顶层在层之间的适当对准。 手术闭孔器可以由一次性或可重复使用的材料构成，例如金属或高压灭菌聚合物。 虽然已经参照本发明的示例性实施例特别示出和描述了某些实施例，但是本领域普通技术人员将会理解，在不脱离本文所定义的精神和范围的情况下，可以对其形式和细节进行各种改变 以下权利要求。
