The Future of Surgery is Here

A groundbreaking development in medicine has taken place as a humanoid robot, mimicking human movements, successfully performed surgery on live patients. Specifically, it completed two laparoscopic cholecystectomy procedures.

This innovation hints at a future where such advanced machines might help address healthcare shortages, support surgeons, and make essential treatments more accessible, especially in areas that lack sufficient medical services.

Michael Yip, a faculty member at the University of California, San Diego, and a senior author of the study, stated, “This study shows that humanoid robots have a viable future in surgery.” He elaborated on the potential for deploying these robots in hard-to-reach environments, like remote communities or emergency situations requiring rapid medical response.

“This will help address health crises not only in the United States but around the world,” he emphasized.

The research describes two surgeries that tested this robotic technique. In the first operation, a humanoid robot functioned as the lead surgeon with assistance from a human. The second surgery utilized an entirely robotic pair.

In both cases, the robot effectively performed essential surgical tasks, such as retrieving tissue, dissection, and gallbladder removal from two pigs—a significant step towards future human clinical trials.

Importantly, the robots weren’t operating autonomously. A trained human surgeon remotely controlled them, guiding their actions from a distance.

Interestingly, the researchers didn’t create a unique robot for their experiments. They began with two commercially available humanoid robots, specifically a Unitree G1 model, modified to manage instruments used in minimally invasive surgery. This robot, standing about five feet tall and weighing around 60 pounds, costs less than $20,000.

This method presented notable advantages. Unlike conventional robotic systems designed for very specific tasks, humanoid robots like those used in this study can be adapted for a variety of roles, both inside and outside the operating room.

The smaller size and lower cost of these robots could facilitate their use in rural hospitals and other areas where medical resources are scarce, the researchers noted.

Dr. Shangrai Liu, another senior author who controlled the robot during the surgeries, remarked on the reduced cost and space requirements of these robots, which may allow for easier deployment in diverse settings.

Given that more than 80% of the U.S. population lives in regions lacking adequate healthcare infrastructure, this flexibility is especially significant. Research suggests that about one in three Americans experiences issues related to medical deserts.

However, it’s wise not to expect humanoid robots in operating rooms anytime soon.

The technology is still developing, and the study points out “major technical challenges” that must be addressed before these robots can assist with human patients.

For instance, the robot needed frequent adjustments during procedures, prolonging them compared to surgeries done with today’s specialized robotic systems. Liu noted that such setbacks are typical for emerging technologies, which generally improve over time.

The research team is also focused on minimizing the lag between the surgeon’s actions and the robot’s responses as they explore remote care delivery potentials.

In the short term, scientists suggest that instead of replacing surgeons, robots like Sargy might serve as assistants, retrieving instruments or helping to set up and clean up after procedures.

“Many regions are struggling to adequately staff their surgical teams, which means patients are missing out on treatment,” Yip said.

He concluded with a vision for the future: “Our goal is the operating room of the future, where humanoid robots and humans work together as an integrated team to provide procedures to those in need, both in traditional hospital settings and non-traditional point-of-care scenarios.”
