Cornerstone Robotics Achieves World’s First Clinical Validation of Fully Autonomous Robot-Assisted Surgery

In a landmark advancement for surgical robotics, a team from The Chinese University of Hong Kong (CUHK), in partnership with Cornerstone Robotics-a global leader and unicorn in surgical robotics innovation-has successfully demonstrated the first-ever clinical validation of autonomous surgery using a robot-assisted platform. This breakthrough was unveiled on August 5th in Hong Kong, showcasing the Sentire® Endoscopic Surgical System, an AI-powered robotic platform developed by Cornerstone Robotics that embodies intelligent multitasking surgical automation.

Revolutionizing Robot-Assisted Surgery with Embodied Intelligence

The pioneering research, titled “Surgical Embodied Intelligence for Generalized Task Autonomy in Laparoscopic Robot-assisted Surgery,” was published in Science Robotics, a leading journal in the robotics field with a five-year impact factor exceeding 32. This study marks the first successful in-vivo animal trial of a Chinese-developed surgical robot equipped with advanced AI-driven embodied intelligence. The system demonstrated autonomous multitasking capabilities and seamless human-robot collaboration, validating the clinical feasibility and adaptability of the underlying algorithms. This milestone paves the way for smarter, more accessible robotic surgeries that can dynamically assist surgeons in complex procedures.

Introducing the VPPV Framework: A New Paradigm in Surgical Automation

The research introduces the innovative VPPV framework-Visual Parsing, Perceptual Regression, Policy Learning, and Visual Servoing Control-which integrates robust foundational AI models with reinforcement learning and classical control theory. This hybrid approach enables the Sentire® system to perform autonomous surgical tasks with unprecedented stability, flexibility, and repeatability. Unlike previous systems reliant on rigid pre-programmed rules, this vision-based intelligence framework supports full perception, multitasking, precise closed-loop control, and cooperative human-robot interaction, significantly lowering barriers to clinical adoption and accelerating the development of next-generation intelligent surgical assistants.

Training with SurRoL: An Open-Source Simulator for Surgical AI

To develop and validate these capabilities, the team utilized SurRoL, an independently developed open-source surgical embodied intelligence simulator. SurRoL combines multimodal sensory inputs, a physics-based simulation engine, and reinforcement learning algorithms to train AI models capable of zero-shot transfer from simulation to real-world surgical environments. This comprehensive platform includes a surgical control interface, simulation engine, and learning modules, enabling rapid iteration and robust generalization across diverse surgical tasks.

Comprehensive Ex Vivo and In Vivo Testing on the Sentire® System

To replicate realistic surgical conditions, the researchers conducted extensive experiments on ex vivo porcine stomach tissue preserving critical vascular structures, as well as in vivo trials on a live pig weighing approximately 30 kilograms. These tests were performed exclusively using the Sentire® Endoscopic Surgical System, developed entirely by Cornerstone Robotics. During the in vivo phase, the system operated in a novel supervised autonomy safety mode, relying solely on its high-definition stereoscopic endoscope without external sensors. It autonomously executed complex assistive tasks such as gauze retrieval, soft tissue manipulation, and blood vessel clipping, demonstrating remarkable adaptability to dynamic environments, stable control, and strong potential for clinical translation.

Cornerstone Robotics’ Vertically Integrated, AI-Ready Surgical Platform

Dr. Jerry Wang, Co-Founder, CTO, and COO of Cornerstone Robotics, emphasized the significance of the Sentire® system’s fully self-developed architecture. “Our platform integrates proprietary mechanical design, electrical systems, software frameworks, robotic algorithms, imaging technologies, and advanced energy control into a commercial-grade robotic system. This vertical integration ensures the precision and robustness necessary for deploying AI autonomy in complex surgical settings,” he explained.

Dr. Wang further highlighted the company’s commitment to full-stack innovation: “By independently developing every component and maintaining a vertically integrated approach, we create scalable, AI-ready systems that can rapidly adapt to evolving surgical needs. This foundation is critical for advancing intelligent surgery and expanding the scope of robot-assisted procedures.”

Bridging Research and Clinical Practice: Accelerating AI-Driven Surgical Innovation

Cornerstone Robotics collaborated closely with CUHK researchers to implement and validate the autonomous algorithms on the Sentire® platform, marking a significant step toward clinical application. This partnership not only confirms the versatility and compatibility of Cornerstone’s open-source infrastructure but also accelerates the translation of AI-powered surgical assistance from experimental labs to real-world operating rooms.

Professor Samuel Au, Founder and CEO of Cornerstone Robotics, remarked, “The fusion of academic research and industry expertise is essential for breakthroughs in medical technology. This achievement validates the practical use of embodied AI on a commercial robotic platform and highlights its transformative potential in surgical automation. We are dedicated to expanding collaborations worldwide to explore new frontiers in task automation, human-robot synergy, and intelligent system monitoring, ultimately bringing smart surgical robots into everyday clinical practice.”
