Manipulation in Laparoscopic Surgery: Overview of Impeding Effects and Supporting Aids

Abstract

Within a Dutch research program on minimally invasive surgery, a large literature survey has been carried out. This article describes the state of the art in research on manipulation in laparoscopy. It gives an overview of factors impeding the surgeon and technical developments designed to overcome these problems. Starting from the year 1991, a large number of journals, proceedings, patents, and books have been consulted. The survey was completed with a thorough MEDLINE search. The impeding effects have been subdivided into two groups: transformation of spatial and grasping movements of the hand. The article gives an overview of these effects and of supporting aids that have been developed. The studies show that many aids are based on a technology-driven rather than a clinically-driven approach. The development of simple instruments that can be used for a large range of tasks instead of only one is still a very important topic of research.
