UCSD researchers successfully demonstrate the first in-vivo teleoperated surgical procedures using general-purpose humanoid robots.

Researchers at the University of California San Diego (UCSD) have achieved a milestone in medical robotics by using Unitree G1 general-purpose humanoid robots (nicknamed "Surgie") to perform laparoscopic gallbladder removals on live animal subjects. The study, published in Nature, evaluated a teleoperated humanoid platform that utilizes standard surgical instruments via custom-made hand adapters. In the trials, the researchers successfully demonstrated both human-robot teams (a humanoid operated by a teleoperator assisting a human surgeon) and robot-robot teams (two humanoids working cooperatively) to complete the surgical tasks. This research indicates that while humanoid platforms are currently slower and less precise than specialized systems like the da Vinci, they offer a far more compact, versatile, and cost-effective alternative that could expand surgical access to remote, rural, or emergency settings.

// ANALYSIS

This is a major paradigm shift away from highly specialized, multi-million-dollar surgical systems like the da Vinci toward commoditized, general-purpose humanoid hardware adapted for surgery.

–**Hardware Agnosticism:** By using custom hand adaptors to interface with standard surgical tools, the research demonstrates that general-purpose humanoids can bypass the need for bespoke, expensive surgical end-effectors.
–**Cost and Portability:** A Unitree G1 costs a fraction of a da Vinci system, making surgical teleoperation economically and logistically feasible in austere, resource-limited, or military environments.
–**Latency and Precision Bottlenecks:** Despite the conceptual breakthrough, the system's end-to-end teleoperation latency and precision limits mean it is not yet ready for human clinical trials, currently lagging behind specialized surgical systems.
–**Cooperative Robotics:** Showing that two humanoid robots can coordinate to perform dual-arm laparoscopic procedures (one holding the camera/retracting tissue and the other operating) opens up new avenues for fully teleoperated remote operating rooms.
