A technical review of flexible endoscopic multitasking platforms.

Area of Science:

• Medical Engineering
• Surgical Technology
• Gastroenterology

Background:

• Development of advanced therapeutic endoscopic techniques and Natural Orifice Translumenal Endoscopic Surgery (NOTES) necessitates a robust flexible endoscopic multitasking platform.
• Such platforms are vital for enhancing minimally invasive surgical procedures.

Purpose of the Study:

• To review and classify existing flexible endoscopic multitasking platforms.
• To identify their functionalities, limitations, and areas for future development.

Main Methods:

• A Medline search was conducted from 2004-2011.
• Keywords included "Flexible endoscopic multitasking platform," "NOTES," "Instrumentation," and "Endoscopic robotic surgery."
• Key articles and their references were reviewed.

Main Results:

• Flexible multitasking platforms are categorized as mechanical or robotic.
• Mechanical systems include Dual Channel Endoscope (DCE) and Incisionless Operating Platform (IOP).
• Robotic systems include MASTER and Viacath; challenges include hysteresis and the need for multiple operators.

Conclusions:

• Further research is needed to improve instrument precision, control, and ergonomics.
• Exploring alternative actuation and camera control methods is recommended.
• Reducing system size and required assistance is essential for broader clinical application.
