One of the keys to safe laparoscopic or thoracoscopic surgery is an expeditious and reliable access to the region of interest. To minimise the risk of accidental injury to major vessels, lung, intestine and other important structures the principle of controlled visualised access has been advocated. This has led to several developments in the field of trocars, cannulae and puncture techniques. Examples are the insertion of a needle scope into a Veress needle, complex access cannulae and our new principle of using an "optical scalpel". The direct visualisation of an active, controllable penetration of the abdominal wall is expected to become indispensable. A selected variety of endoscopically assisted trocar and cannula systems such as the "windowed trocar", the "optical trocar", the "Visiport" and the "optical scalpel" are described.
安全的腹腔镜或胸腔镜手术的关键之一是能够迅速且可靠地进入感兴趣区域。为将意外损伤大血管、肺、肠及其他重要结构的风险降至最低，人们倡导可视化可控入路原则。这促使了套管针、插管及穿刺技术领域的多项发展。例如将针状内镜插入韦雷斯针、复杂的入路套管，以及我们使用“光学手术刀”的新原则。预计腹壁主动可控穿刺的直接可视化将变得不可或缺。本文描述了多种内镜辅助套管针和插管系统，如“开窗套管针”、“光学套管针”、“可视端口”和“光学手术刀”。
