Magnetic instrumentation and other applications of magnets in NOTES

Abstract

Modern surgery is developing towards a minimally invasive approach. To minimize the trauma the number of ports is either limited as in single incision laparoscopic procedures or ports are introduced through natural orifices as in natural orifice translumenal endoscopic surgery (NOTES). To provide surgeons with appropriate instrumentation novel technologies are employed involving magnets. This article summarizes the theoretical background, technology and currently developed magnetic instrumentation for NOTES, laparoscopic surgery and endoscopy. Moreover, current limitations and future goals are addressed to outline the prospects for use of magnetic instrumentation in the surgery of tomorrow.
