A team of researchers at the University of California San Diego has successfully utilized teleoperated humanoid robots to perform surgeries, demonstrating the potential for these advanced technologies to assist in medical procedures and address the global shortage of surgeons.
Researchers at the University of California San Diego (UCSD) have made significant strides in surgical technology by successfully employing teleoperated humanoid robots to perform two surgeries during a preclinical trial. This groundbreaking achievement represents a pivotal moment in the integration of robotics into medical practice, aiming to enhance surgical capabilities and accessibility, particularly in underserved regions.
Details of the Surgical Procedures
The surgeries conducted included a gallbladder removal that involved a collaboration between a human surgeon and a humanoid robot, as well as a second procedure executed by two humanoid robots working in tandem. Both operations were performed on large nonprimate mammals, marking a first in the application of humanoid robots in surgical contexts.
According to the research team, these procedures illustrate the potential of teleoperated humanoid robots to support surgeons in operating rooms and to perform surgeries remotely. The implications of this technology extend beyond mere assistance, with possibilities for handling a variety of surgical tasks in challenging environments.
Addressing Global Surgical Needs
The introduction of teleoperated and autonomous humanoid robots could serve as a solution to the global shortage of surgeons, which is particularly acute in many underserved areas where access to specialized medical care is limited. The humanoid robots, with their human-like form and versatility, could perform a broader range of clinical tasks compared to conventional robotic surgical platforms. This flexibility renders them suitable for deployment in hospitals, remote communities, disaster zones, and during search-and-rescue operations.
Current robotic surgery systems are often highly specialized, typically consisting of three or four robotic arms, proprietary software, and dedicated surgical instruments. These systems can weigh around 1,800 pounds (816 kg) and require purpose-built operating rooms along with extensive setup and trained personnel, factors that contribute to high costs and logistical challenges, making them impractical for use outside major medical centers.
In contrast, the humanoid robots utilized in the UCSD study, named Surgie, stand approximately 5 feet (1.5 meters) tall and weigh only 60 pounds (27 kg). Their compact design allows them to function effectively within existing operating rooms without necessitating significant infrastructure changes, making them a more viable option for resource-limited healthcare settings.
Integration into Surgical Workflow
For the surgical procedures, researchers equipped the humanoid robots with adapters that enabled them to utilize standard surgical instruments. The robots seamlessly integrated into existing clinical workflows, with operators reporting that the human-like controls offered a more intuitive experience compared to traditional robotic surgery systems. The UCSD team asserts that the teleoperated humanoid robots demonstrated surgical precision comparable to established robotic platforms, suggesting that compact humanoid systems could deliver high-quality surgical performance while enhancing accessibility to advanced care in challenging environments.
Challenges Ahead for Implementation
Despite the promising outcomes of the study, several technical challenges must be addressed before the widespread adoption of this innovative technology can occur. During the surgeries, the robots required multiple recalibrations, which extended the overall operating time in comparison to conventional robotic surgical systems. Researchers acknowledged that such limitations are typical during the early stages of new surgical technologies, recalling that initial robotic laparoscopic procedures could take several hours, but advancements have since reduced that timeframe to approximately 30 minutes.
Another challenge involves communication latency—the delay between a surgeon’s control inputs and the robot’s movements. Mitigating this delay is essential as researchers aim to facilitate long-distance teleoperated surgeries, particularly in remote and underserved regions.
Future Vision for Humanoid Robots in Medicine
Beyond performing surgical tasks, the research team envisions humanoid robots taking on expanded roles within operating rooms. Their capacity to walk and manipulate objects could enable them to retrieve instruments, assist medical staff with routine tasks, and clean operating rooms post-surgery, thereby improving workflow and alleviating pressure on healthcare teams.
Michael Yip, a faculty member in the UCSD Department of Electrical and Computer Engineering and a senior author of the study, stated, “Our goal is an operating theater of the future, where humanoid robots and humans work side by side as an integrated team to deliver procedures to those in need, both in traditional hospital settings as well as in nontraditional, field medicine scenarios.”
