From medical tourism to ‘medical export’: India's remote robotic surgery opens new frontier

With advanced robotic systems and 5G connectivity, top-tier surgeons can now operate on patients thousands of kilometers away, flipping the script from "medical tourism" to "medical export."

For decades, specialized healthcare followed a rigid, geographic law: if a patient required the expertise of a world-class surgeon, either the patient or the surgeon had to board a plane. This paradigm gave rise to medical tourism, a multi-billion-dollar global industry, but one burdened by high travel costs, logistical stress, and the physical vulnerability of patients traveling post-surgery.

Today, that paradigm is fracturing. We are entering the era of "telesurgery"—remote robotic procedures that allow a surgeon sitting at a console in one city to operate on a patient lying on a table thousands of miles away with millimeter precision. Propelled by ultra-low-latency 5G networks, satellite communications and cutting-edge surgical platforms, the operating room has officially become borderless.

To understand how this technology works, the critical infrastructure it demands, and the legal and ethical questions it raises, Firstpost spoke with Dr. Yuvaraja T.B, Director (Group) of Uro-Oncology & Robotic Surgery at Kokilaben Dhirubhai Ambani Hospital (Mumbai). Dr. Yuvaraja breaks down the reality of long-distance surgery, India’s digital readiness and why the human hand will never truly be replaced by an algorithm.

What specific features of the Medbot Toumai system enable a surgeon to operate from thousands of kilometers away with the same precision as being bedside?

Dr. Yuvaraja: The Medbot Toumai system (a next-generation surgical robot designed for complex, minimally invasive procedures) uses two identical surgical consoles connected to the same patient-side robotic cart. Only one surgeon can actively control the robot at a time, and control can be instantly transferred using a takeover button, while the other surgeon observes or guides.

Every hand movement is transmitted digitally over the internet and executed in real time by the robotic instruments. The 3D immersive vision system makes it feel like the surgeon is operating directly inside the body, even from a remote location.

In remote surgery, "latency" (the time delay between a surgeon's movement and the robot's reaction) is the biggest hurdle. What is the maximum delay (in milliseconds) the system can handle before it becomes unsafe for the patient?

Dr. Yuvaraja: The internationally accepted safety limit for latency is between 100 to 150 milliseconds. Below 100 milliseconds, it feels incredibly close to operating locally. In most cases, surgeons adapt to the slight delay within five to ten minutes, making it highly manageable even across such significant geographic distances.

How does the system’s force-sensing technology compensate for the lack of physical "touch" or tactile feedback during a remote procedure?

Dr. Yuvaraja: One of the biggest concerns in remote robotic surgery is the absence of direct tactile sensation that surgeons are traditionally accustomed to during open or laparoscopic (keyhole) procedures. The system addresses this through advanced force-sensing technology integrated into the robotic instruments.

The platform continuously measures the amount of force being applied to tissues in real time and translates that into precise visual and sensory cues for the surgeon at the console. This allows us to gauge tissue resistance, tension, and pressure with remarkable accuracy, helping prevent excessive force or unintended injury.

In many ways, the technology actually enhances surgical precision because the robotic platform can detect and quantify forces beyond what the human hand can naturally perceive. Combined with high-definition 3D visualization, motion scaling (which shrinks large hand movements into microscopic robotic movements), tremor filtration, and AI-assisted stability, the surgeon is able to operate with a very high degree of confidence and control, even across long distances.

"That said, remote robotic surgery is never dependent on technology alone. It works because of the combination of advanced robotics, robust network infrastructure, rigorous safety protocols, and an experienced on-ground surgical and anesthesia team working in complete coordination."

What are the "fail-safe" protocols if the 5G or satellite connection drops mid-surgery?

Dr. Yuvaraja: This is something that is planned for very carefully. A full surgical team, along with a senior surgeon, is physically present in the operating room throughout the entire procedure. The moment a connectivity drop occurs, the local team takes over immediately without any gap in care.

The surgery simply continues as a standard robotic or open procedure. Responsibility always stays with the local hospital and surgeon on the ground, ensuring the patient is never left without expert hands nearby.

We are moving from "medical tourism" to "medical export." How does this technology allow Indian doctors to treat global patients without anyone crossing a border?

Dr. Yuvaraja: What this essentially does is bring the surgeon to the patient, not the other way around. The surgeon, wherever they are physically located, controls the instruments entirely through internet-based transmission, meaning patients do not need to cross borders or travel at all.

The same setup also opens the door for real cross-country teaching and mentoring. Expert surgeons can guide and train colleagues in other countries using the exact same system, which adds enormous value beyond just direct patient care.

Is the current digital infrastructure in India’s Tier-2 cities robust enough to support a remote robotic surgical unit today?

Dr. Yuvaraja: India is closer than many people assume, but we are not uniformly ready yet. For a remote robotic surgical unit to function safely, three things are absolutely non-negotiable:

*Ultra-low latency connectivity

*Uninterrupted power and network redundancy (backup systems)

*A highly trained, on-ground clinical team

In select Tier-2 cities, India can already support this ecosystem today. Across the broader Tier-2 landscape, however, readiness remains uneven.

India’s 5G expansion now covers nearly all districts, and Tier-2 cities are increasingly becoming digital infrastructure hubs. These developments make remote-assisted and tele-mentored robotic surgery increasingly feasible. But "remote robotic surgery" requires a much higher threshold of reliability than basic telemedicine or AI-assisted diagnostics.

Many Tier-2 hospitals continue to face fragmented health IT systems, inconsistent infrastructure quality, limited interoperability (the ability of different systems to share data), and shortages of trained robotic surgery personnel. In effect, India’s digital backbone is becoming strong enough for “distributed surgical excellence,” but the last mile—infrastructure reliability, training depth, medico-legal frameworks, and standardization—still needs maturation before remote robotic surgery becomes routine nationwide.

Globally too, remote robotic surgery remains limited and carefully controlled, even in highly developed healthcare systems. India is not behind the curve; it is entering the curve.

Beyond oncology (cancer treatment) and urology, which other surgical specialties are most ready for high-volume, remote adoption?

Dr. Yuvaraja: Currently, the global focus is on urological cancers—prostate, kidney, and bladder—along with gynecological procedures such as uterus removal (hysterectomy). Cases are meticulously selected, with lower-risk procedures prioritized during this early phase of adoption.

The surgical approach itself does not change whether the surgery is remote or in-person. Surgical indications remain the same, and more specialties are actively being trained to join the system going forward.

How does the cost of a remote robotic procedure compare to traditional surgery when you factor in the elimination of patient travel and faster recovery times?

Dr. Yuvaraja: The surgery itself is priced the same as standard robotic surgery. What changes drastically is the overall financial burden on the patient. Travel, accommodation, and the cost of bringing family members along—expenses that add up very quickly, are eliminated entirely.

For patients traveling from distant cities or other countries, that saving is significant. Beyond the financial aspect, the reduction in logistical stress also improves the overall recovery experience considerably.

From a regulatory standpoint, which country’s medical board is legally liable if a complication occurs during a cross-border surgery?

Dr. Yuvaraja: Permission for cross-border telesurgery is acquired by the robot manufacturer and approved by the Indian regulatory authority, the CDSCO (Central Drugs Standard Control Organisation). Once that approval is in place, surgery can be performed remotely from anywhere in the world.

However, legal liability remains clear: regardless of where the operating surgeon is physically located, primary responsibility always lies with the surgeon performing the procedure and the hospital where the patient is actively being treated.

By 2030, do you envision a future where "fully autonomous" robotic steps, monitored remotely by a human, become the standard of care?

Dr. Yuvaraja: By 2030, I believe we will certainly see robotic surgery becoming far more intelligent, automated, and deeply integrated with AI-driven decision support. Certain repetitive and highly standardized surgical steps, such as suturing assistance, camera navigation, tissue mapping, or precision-guided movements, may increasingly be performed autonomously under the close supervision of a surgeon.

However, I do not foresee fully autonomous surgery completely replacing human surgeons as the standard of care within this decade. Surgery is far more than a mechanical process. Every patient presents unique anatomical variations, unexpected intraoperative findings, and clinical complexities that require real-time judgment, adaptability, and ethical decision-making—areas where human expertise remains irreplaceable.

The future is more likely to be one of "augmented surgery," where robotics and AI enhance the surgeon’s capabilities rather than eliminate the surgeon from the equation. The surgeon will continue to remain at the center of decision-making, while intelligent robotic systems improve precision, consistency, safety, and access to specialized care, especially in remote and underserved regions.

What is truly exciting is that advancements in connectivity, robotics, imaging, and AI are gradually enabling the possibility of expert surgical care transcending geographical boundaries. That has the potential to fundamentally redefine access to healthcare globally.
