  • Clinical evaluation of complete solo surgery with the “ViKY^®” robotic laparoscope manipulator
    Surgical Endoscopy, 2017
    Co-Authors: Masahiro Takahashi, Masanori Takahashi, Naoto Nishinari, Hideki Matsuya, Tsutomu Tosha, Yukihiro Minagawa, Osamu Shimooki, Tadashi Abe
    Abstract:

    Background Advancement in both surgical technique and medical equipment has enabled solo surgery. ViKY^® Endoscope Positioning System (ViKY^®) is a robotic System that remotely controls an Endoscope and provides direct vision control to the surgeon. Here, we report our experience with ViKY^®-assisted solo surgery. Methods We retrospectively examined 25 cases of solo surgery TAPP with ViKY^®. ViKY^® was setup by the surgeon alone, and the setup duration was determined as the time at which the side rail was positioned and that when the Endoscope was installed. For assessing the control unit, the number of false movements was counted. We compared the operative results between ViKY^®-assisted solo surgery TAPP and the conventional method with an assistant. Results The average time to set up ViKY^® was 7.9 min. The average number of commands for ViKY^® during surgery was 98.3, and the average number of errors and no response of control unit was 7.9. The mean duration of surgery was 136 min for the ViKY^® group, including the setup time, and 117 min for the conventional method. No case required an assistant during the operation. There was also no difference between the two groups with regard to postoperative complications and the rate of recurrence. Conclusions ViKY^® proved reliable in recognizing orders with very few failures, and the operations were performed safely and were comparable to the conventional operations with assistants. Solo surgery with ViKY^® was beneficial in this clinical evaluation.

  • A new remote-controlled Endoscope Positioning System for endoscopic solo surgery
    Surgical Endoscopy, 2000
    Co-Authors: G. F. Buess, F. Ulmer, L. Gumb, T. Testa, Marc Oliver Schurr, H. Fisher, Alberto Arezzo, C. Nobman
    Abstract:

    In the field of endoscopic solo surgery, the assistance received by the surgeon from ergonomical Positioning devices is extremely important. They aid in both the retracting of instruments and the Positioning of the Endoscope. However, passive Systems derived from open surgery have not proved satisfactory. Therefore, we set out to develop a remote-controlled arm capable of moving a rigid Endoscope with about four degrees of freedom, while maintaining an invariant point of constraint motion coincident with the trocar puncture site through the abdominal wall. The System is driven by means of speaker-independent voice control or a finger-ring joystick clipped onto the instrument shaft close to the handle. When the joystick is used, the motion of the Endoscope is controlled by the fingertip of the operating surgeon, which is inserted into the small ring of the controller in such a way as to make the motion of the fingertip correspond directly to the motion of the tip of the Endoscope. A study was performed to compare the two different interfaces available for the System. With both interfaces, the guiding System allows for transparent and intuitive operation. Its set-up is easy; it is safe and reliable to use during the intervention; and it is faster than human assistance. With its improved ergonomy, this new generation of remote-controlled Endoscope Positioning System represents a further step toward the diffusion of solo surgery techniques in minimally invasive therapy. In our opinion, this prototype creates a valid compromise between human and robotic control of rigid Endoscopes.

    Abstract:

    In the field of endoscopic solo surgery, the as- sistance received by the surgeon from ergonomical posi- tioning devices is extremely important. They aid in both the retracting of instruments and the Positioning of the endo- scope. However, passive Systems derived from open surgery have not proved satisfactory. Therefore, we set out to de- velop a remote-controlled arm capable of moving a rigid Endoscope with about four degrees of freedom, while main- taining an invariant point of constraint motion coincident with the trocar puncture site through the abdominal wall. The System is driven by means of speaker-independent voice control or a finger-ring joystick clipped onto the in- strument shaft close to the handle. When the joystick is used, the motion of the Endoscope is controlled by the fin- gertip of the operating surgeon, which is inserted into the small ring of the controller in such a way as to make the motion of the fingertip correspond directly to the motion of the tip of the Endoscope. A study was performed to compare the two different interfaces available for the System. With both interfaces, the guiding System allows for transparent and intuitive operation.
