Development of a Robotic Driven Handheld Laparoscopic Instrument for Non-invasive Intraoperative Detection of Small Endoluminal Digestive Tumors

摘要

The present paper introduces the development of a sensing laparoscopic instrument based on a framework design for guiding decision-makers towards a superior balance between quality, efficiency and surgical procedure issues in medical instruments development. A prototype of the robotic handheld sensitive laparoscopic instrument for non-invasive intraoperative detection of small endoluminal digestive tumors was designed and developed for validation the instrument. The developed prototype was evaluated by two surgeons in ex vivo experimental conditions by different medical approaches - open and laparoscopic surgery. The surgeons found that the developed prototype is easy to use, satisfactory and useful in precise detection of small endoluminal digestive tumors in 85 % of cases.
