Area of Science:

  • Aerospace Medicine
  • Surgical Innovation
  • Space Exploration Technology

Background:

  • Microgravity surgery feasibility demonstrated through prior simulations and porcine experiments.
  • Need for advanced yet accessible surgical techniques for spaceflight, manageable by less experienced crew medical officers (CMOs).
  • Hand-assisted laparoscopic surgery (HALS) offers patient benefits (smaller incisions, faster recovery) and aids less experienced surgeons.

Purpose of the Study:

  • Evaluate the utility of HALS in microgravity using an inexpensive inanimate surgical simulator.
  • Assess HALS's suitability for spaceflight surgical care.
  • Provide a training platform for CMOs in microgravity surgical procedures.

Main Methods:

  • Construction of an inexpensive inanimate surgical simulator.

  • Performance of simulated surgical tasks, including intestinal exploration and appendix ligation, by a physician-astronaut and an experienced laparoscopic surgeon.

    • Main Results:

    • Successful performance of simulated HALS in microgravity.
    • Effective containment of surgical equipment and fluids within the simulated abdominal cavity by HALS.
    • Positive astronaut and surgeon feedback suggesting HALS's potential for facilitating minimally invasive surgery (MIS) in space.

    Conclusions:

    • HALS shows significant promise for microgravity surgical applications, especially for extended space missions beyond low Earth orbit.
    • HALS combines MIS benefits with enhanced ease of use for less experienced CMOs, while managing the operative field.
    • Simulation is a cost-effective method for evaluating space medical technology and training CMOs for on-orbit procedures.
