In vivo feasibility study of humanoid robots in surgery
🤖 AI Summary
This study addresses the stringent demands of minimally invasive surgery for precision, control, and safety by exploring the potential of general-purpose humanoid robots in laparoscopic procedures. We developed a teleoperation framework based on standard surgical instruments and comprehensively evaluated its technical feasibility and clinical readiness through benchtop testing, dry-lab user studies, and, for the first time, systematic in vivo experiments on live porcine models. The results demonstrate that humanoid robots possess preliminary capability to perform laparoscopic tasks, thereby validating their potential to transcend the paradigm of conventional specialized surgical robots. Nevertheless, the findings also highlight critical challenges that remain to be addressed, particularly concerning operational accuracy, system stability, and patient safety.
📝 Abstract
Recent advances in actuation, control and learning have rapidly pushed humanoid robots from a distant vision towards near-term real-world deployment. Healthcare is a particularly pressing domain, in which staffing shortages and increasing care demand are widening the gap between clinical workload and available skilled labour. Although current automation has largely focused on digital and logistical tasks, much hospital work remains embodied, requiring mobility, manipulation and safe interaction in human-designed environments. Humanoid form factors offer unique potential, particularly for assisting with surgical tasks. Traditionally, robotic systems for surgery are purpose-built platforms such as Intuitive Surgical's da Vinci Surgical System, and it remains unclear how close current humanoid systems are to meeting the precision, control and safety requirements of minimally invasive surgery. Here we present a systematic evaluation of contemporary humanoid technology for laparoscopic surgical tasks. We develop a humanoid-based laparoscopic teleoperation framework using general-purpose instruments and assess its abilities through benchtop characterization, dry-laboratory user studies spanning diverse surgical experience levels and in vivo porcine studies. Across these evaluations, we quantify technical feasibility, task performance and clinical readiness relative to established surgical platforms. Together, our study provides an evidence-based assessment of current humanoid abilities and limitations for surgical applications, highlighting both their promise and key technical challenges that must be addressed before clinical deployment.
