The importance of a safer approach to the abdominal cavity 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". In our view, direct optical visualization and actively controllable penetration of the abdominal wall are mandatory. First experimental and clinical applications indicate the newly developed "optical scalpel" (Olympus Winter & Ibe, Hamburg, Germany) as a reliable and useful instrument for a safe approach to the endoscopic operative field. This instrument was successfully used in 10 endoscopic operations and is currently undergoing further clinical testing.
采用更安全的方式进入腹腔的重要性推动了套管针、插管和穿刺技术领域的多项发展。例如，将针式内镜插入韦雷斯针、复杂的穿刺套管以及我们使用“光学手术刀”的新原理。我们认为，直接的光学可视化和对腹壁的主动可控穿刺是必不可少的。初步的实验和临床应用表明，新开发的“光学手术刀”（德国汉堡奥林巴斯温特与伊贝公司）是安全进入内镜手术视野的可靠且有用的器械。该器械已成功应用于10例内镜手术，目前正在进行进一步的临床试验。
