Cancer - Kidney(비디오) (V-015) Tips and tricks for a true single-site surgery with the da Vinci SP platform: how to increase working range of bedside assistant Urology, Yongin Severance Hospital, Urology, National Cancer Center, Urology, Hanyang University Medical Center, Urology, Ewha Womans University Seoul Joon Chae Na, Hyung Ho Lee, Young Eun Yoon, Kwang Hyun Kim, Woong Kyu Han "Comment: Although the da Vinci SP platform has been developed for single-site surgery many surgeons prefer to place an additional assistant port. This owes to the limited working space of the bedside assistant when assisting through the same incision with the multichannel robotic port. Thus, we introduce the following tips and tricks to increase the working range of the bedside assistant during a true single-site surgery with the SP platform. (1) Remove the robotic instrument in the #2 channel opposite to the camera if possible. This will improve access to central area of the visible field. (2) In order to increase the working range on the left side, raise up the robotic instrument on the left. (3) When the robotic instrument needs to keep its position and method (2) is not possible, rotate the SP robot clockwise. (4) Utilizing the robotic joints will further improve downward accessibility. Bow down the SP port and raise up the robotic camera and instruments. These methods will help increase the working range of assistant instruments in all directions. / Video URL: https://youtu.be/xv0wMxSQKfY"
