Modern surgery is looking for ways to carry out procedures which limit unnecessary damage to the patient. This means, in practice, using smaller incisions and special tools. An instrument for removing tissue through a small cross-section has been developed. It is suitable for both endoscopy and laparoscopy. The instrument and its development is described, and its performance evaluated in vitro and for a range of clinical procedures. Experiments aimed at uncovering the mechanism of cutting are discussed as to their relevance for practical instrument development.
现代外科手术正在寻找方法来实施那些能将对患者的不必要损伤降至最低的手术。实际上，这意味着要使用更小的切口和特殊工具。一种用于通过小横截面切除组织的器械已经研发出来。它适用于内窥镜检查和腹腔镜检查。本文描述了该器械及其研发过程，并在体外和一系列临床手术中对其性能进行了评估。还讨论了旨在揭示切割机制的实验与实际器械研发的相关性。
