The future of surgery in space exploration

Area of Science:

• Aerospace Medicine
• Surgical Robotics
• Human Physiology in Space

Background:

• Long-duration space missions pose unique surgical risks due to microgravity and limited medical support.
• Astronauts face physiological changes and potential emergencies like trauma or intra-abdominal pathologies.
• Evacuation is impossible and communication delays hinder real-time surgical intervention.

Purpose of the Study:

• To assess the feasibility and requirements of robot-assisted surgery for long-duration human space missions.
• To identify challenges and potential solutions for performing surgery in microgravity.
• To explore translational applications of space-based surgical robotics for terrestrial healthcare.

Main Methods:

• A comprehensive literature review was conducted across PubMed, Scopus, and aerospace medicine databases.
• Studies focused on spaceflight surgical risks, robotic surgical systems, and tele-operation were thematically synthesized.
• Feasibility was evaluated based on simulated and orbital environment studies.

Main Results:

• Miniaturized robotic systems with tele-mentored and semi-autonomous capabilities show promise for space surgery.
• These systems can overcome challenges like latency, sterility, and limited crew expertise.
• Robotic surgery in space has potential applications for remote and low-resource settings on Earth.

Conclusions:

• Robot-assisted surgery is a mission-critical capability for deep-space exploration.
• Challenges in system reliability, training, ethics, and resources must be addressed.
• Developing integrated frameworks will enable safe tele-operated surgery in extreme environments and improve global surgical equity.
