Preclinical Implementation of a Steerable, Da Vinci Xi ® Compatible CO2‐Laser Fiber Carrier for Transoral Robotic Surgery (TORS): a Cadaveric Feasibility Study

xlomafota13 shared this article with you from Inoreader Preclinical Implementation of a Steerable, Da Vinci Xi ® Compatible CO2‐Laser Fiber Carrier for Transoral Robotic Surgery (TORS): a Cadaveric Feasibility Study Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Introduction Monopolar electrocautery is the most common dissection and coagulation tool during transoral robotic surgery (TORS) but causes significant collateral tissue damage as opposed to CO2 laser. We aimed at combining both modalities in one robotic instrument arm. Methods We developed a steerable CO2-laser fiber carrier serving as an add-on to the existing Endowrist® monopolar spatula of the Da Vinci Xi. Feasibility and safety were assessed in a preclinical setting. Results One radical tonsillectomy with monopolar cautery and 3 with the instrument prototype were performed in 2 cadavers by 2 surgeons. No serious prototype-related intra-operative difficulties were observed. Safe and efficient switching between energy sources proved possible in all simulated intra-operative bleeding events. Prototype use allowed for the identification of the majority of key anatomical structures and was scored favorably on NASA-TLX ques tionnaires. Discussion The reported prototype successfully combines the advantages of CO2-laser with the advantages of TORS. This article is protected by copyright. All rights reserved.
