The hinotori™ system shows promise for robotic gastric resection, demonstrating safe and efficient performance in human cadaver studies for distal and total gastrectomy. Further research is needed to confirm potential benefits like shorter procedure times.

Area of Science:

  • Surgical Robotics
  • Minimally Invasive Surgery

Background:

  • First preclinical evaluation of the hinotori™ system for gastric resection.
  • Utilized human cadaver models for distal and total gastrectomy procedures.

Purpose of the Study:

  • To assess the capabilities of the hinotori™ system in gastric resection.
  • Evaluate safety and performance in complex surgical procedures.

Main Methods:

  • Three robotic distal gastrectomies (RADGs) and one total gastrectomy performed on human cadavers.
  • Utilized a delta-shaped anastomosis with a manual stapler for RADG procedures.

Main Results:

  • Mean operative time for RADGs was 118 minutes; total gastrectomy focused on resection.
  • Procedures were completed safely without complications, with good instrument performance.

  • Ergonomic surgeon cockpit and headrest contributed to successful outcomes.

    • Conclusions:

    • The hinotori™ system's docking-free design and arm mobility offer a wide range of motion.
    • Potential for improved performance and shorter procedure times in multiquadrant surgeries.
    • Further studies are recommended to validate these preliminary findings.
