Initial laboratory experience with a novel ultrasound probe for standard and single-port robotic kidney surgery: Increasing console surgeon autonomy and minimizing instrument clashing

摘要

Background: The aim of this study was to evaluate a novel ultrasound probe specifically developed for robotic surgery by determining its efficiency in identifying renal tumors. Methods: The study was carried out using the Da Vinci? surgical system in one female pig. Renal tumor targets were created by percutaneous injection of a tumor mimic mixture. Single-port and standard robotic partial nephrectomy were performed. Intraoperative ultrasound was performed using both standard laparoscopic probe and the new ProART? Robotic probe. Probe maneuverability and ease of handling for tumor localization were recorded. Results: The standard laparoscopic probe was guided by the assistant. Significant clashing with robotic arms was noted during the single-port procedure. The novel robotic probe was easily introduced through the assistant trocar, and held by the console surgeon using the robotic Prograsp? with no registered clashing in the external operative field. The average time for grasping the new robotic probe was less than 10s. Once inserted and grasped, no limitation was found in terms of instrument clashing during the single-port procedure. Conclusions: This novel ultrasound probe developed for robotic surgery was noted to be user-friendly when performing porcine standard and especially single-port robotic partial nephrectomy.
