Telesurgery: How Remote Surgery Actually Works

Telesurgery sounds like something from the future: a surgeon sitting hundreds or thousands of miles away while robotic instruments operate on a patient in another hospital.

That future is getting closer.

But it is important to separate what is already being used in hospitals from what remains specialized or experimental.

Telesurgery: The use of telecommunications, connected surgical systems, or robotics that allows a surgeon to participate in a surgical procedure from another location. Telesurgery can range from remote guidance and telementoring to direct remote control of robotic surgical instruments.

Today, the word telesurgery can describe several different ways telecommunications are used around an operation.

A surgeon may remotely guide another surgeon.

A specialist may observe or proctor a procedure from another hospital.

A patient may meet with a surgeon by video before or after an operation.

And in true remote robotic surgery, a surgeon can potentially control surgical instruments from another location through a high-speed communications network.

Those are very different things.

Surgical telementoring and virtual surgical care are already practical.

True long-distance robotic surgery is developing quickly, but it is still not routine care for most patients.

What Is Telesurgery?

Telesurgery is the use of telecommunications, connected surgical technology, or robotic systems that allow a surgeon to participate in an operation from another location.

How involved the remote surgeon is can vary dramatically.

At one end, a specialist may watch a live surgical video feed and advise the surgeon in the operating room.

At the other end, a surgeon may actually control robotic surgical instruments from another city or even another country.

That distinction matters.

Surgical Telementoring

With surgical telementoring, the surgeon performing the operation remains physically present with the patient.

A remote expert may:

• watch the surgical field through a laparoscopic or robotic camera;
• communicate directly with the operating surgeon;
• review imaging;
• recommend the next surgical step;
• or use telestration tools to point to anatomy on the live video feed.

Think of it as having another experienced surgeon virtually standing beside the operating table.

The remote surgeon advises.

The local surgeon operates.

Teleproctoring

Teleproctoring uses similar technology but usually serves a different purpose.

Instead of primarily teaching, an experienced surgeon remotely observes another surgeon performing a procedure and evaluates competency.

This can be useful when hospitals introduce:

• new surgical procedures;
• robotic platforms;
• specialized medical devices;
• or procedures requiring supervised cases before privileges are granted.

Instead of flying an expert across the country simply to observe a case, some of that oversight can potentially happen remotely.

Remote Robotic Surgery

True remote surgery goes much further.

The surgeon sits at a control console away from the patient.

Commands from the surgeon are transmitted through a communications network to robotic instruments positioned beside the patient.

The surgeon could be across the hospital.

Across the state.

Or theoretically across the world.

This is the version of telesurgery that receives the most attention.

It is also the version that creates the most difficult questions about network reliability, patient safety, licensing, cybersecurity, credentialing, liability, and emergency backup.

Robotic Surgery Is Not Automatically Telesurgery

This is one of the most common misunderstandings about robotic surgery.

A surgery can be robotic without being remote.

During most robot-assisted surgery today, the surgeon sits at a console in or near the operating room.

The robot is not independently deciding what to cut or where to move.

The surgeon remains in control.

The system translates the surgeon's hand movements into precise movements of instruments inside the patient's body.

Depending on the system and procedure, robotic surgery may provide:

• magnified three-dimensional visualization;
• tremor filtering;
• motion scaling;
• improved instrument articulation;
• and better access to difficult anatomical areas.

The distinction is simple:

Robotic surgery describes how the instruments are controlled. Telesurgery describes where the surgeon is located.

A robotic operation performed with the surgeon ten feet away is not long-distance telesurgery.

Model	Surgeon location	Instrument control	Current role
Conventional surgery	Operating room	Surgeon	Standard care
Robot-assisted surgery	In or near operating room	Surgeon through console	Established
Surgical telementoring	Remote mentor plus local surgeon	Local surgeon	Increasingly practical
Remote robotic telesurgery	Remote location	Remote surgeon through network	Specialized / developing

The Operation That Proved Remote Surgery Was Possible

Modern telesurgery history usually comes back to one operation.

In September 2001, surgeons in New York operated on a patient in Strasbourg, France.

The patient underwent laparoscopic gallbladder surgery while the surgeon controlled a robotic system from the United States.

The procedure became known as the Lindbergh Operation, named after Charles Lindbergh's famous transatlantic flight.

It demonstrated something remarkable.

Surgical commands could be transmitted across the Atlantic quickly enough for a surgeon to perform an actual procedure.

But there was a major limitation.

The communications network had been specially engineered for the operation.

That is very different from assuming an ordinary internet connection will remain fast and reliable enough during surgery.

For years, the Lindbergh Operation represented what telesurgery might become more than what surgeons were regularly doing.

That is beginning to change.

Telesurgery Has Advanced Beyond 2001

The story of remote surgery no longer ends with the Lindbergh Operation.

Modern surgical robotics, fiber networks, 5G connectivity, improved video transmission, and more powerful computing systems have pushed remote surgery further.

Peer-reviewed research has now described remote robotic procedures involving specialties such as:

• gastrointestinal surgery;
• urologic surgery;
• orthopedic and spinal procedures;
• breast surgery;
• and thoracic surgery.

Researchers have also demonstrated remote procedures over very long distances using dedicated high-speed networks.

That matters.

It means remote robotic surgery is no longer only a theoretical concept.

It can be done.

The much harder question is whether it can be performed safely, reliably, economically, and legally enough to become routine medicine.

Those are very different standards.

Why 5G Matters for Telesurgery

If a surgeon moves a robotic instrument with their hand, they expect the instrument to respond almost immediately.

That becomes more difficult when the command has to travel hundreds or thousands of miles.

The delay between the surgeon's movement and the robot's response is called latency.

Even a relatively small delay can matter.

A surgeon is constantly working through a feedback loop:

move → see → adjust → move again

If the visual response or instrument movement arrives late, that feedback loop can become harder to manage.

Latency Is Only Part of the Problem

A surgical communications network also has to deal with:

• jitter, or inconsistent changes in network delay;
• dropped data packets;
• temporary network interruptions;
• bandwidth limitations;
• video compression;
• hardware failures;
• cybersecurity;
• and power outages.

A network that works almost all the time may sound perfectly acceptable for ordinary internet use.

During surgery, "almost all the time" is not necessarily good enough.

That is one reason 5G has become such an important part of telesurgery research.

High-performance 5G networks can potentially offer:

• low latency;
• high bandwidth;
• dedicated network capacity;
• edge computing;
• and more predictable communications.

But the phrase 5G telesurgery can also be misleading.

Seeing a 5G symbol on a phone does not mean a hospital is ready for remote surgery.

Clinical telesurgery requires an engineered communications system where the entire connection is designed for reliability.

What Happens if the Connection Fails?

This may be the most important practical question in telesurgery.

A frozen video call is frustrating.

A frozen surgical connection is something entirely different.

Any serious remote surgery program needs a backup plan.

Depending on the system and procedure, that can include:

• a qualified surgical team physically present with the patient;
• redundant communications connections;
• network monitoring;
• backup power;
• emergency manual-control procedures;
• maximum acceptable latency thresholds;
• and the ability to convert to conventional surgery if necessary.

This creates an interesting problem.

One of the biggest proposed benefits of remote surgery is bringing highly specialized surgical expertise somewhere that does not have it.

But if another highly qualified surgical team still needs to stand beside the patient in case the network fails, some of that benefit becomes less dramatic.

The technology may narrow this problem.

It has not eliminated it.

Where Telesurgery Could Matter Most

The biggest value of telesurgery may not be performing ordinary procedures remotely simply because the technology allows it.

Its real value could be bringing expertise to places where specialized surgeons are difficult to access.

Rural Hospitals

Patients in rural communities may live hours from a large medical center.

Remote surgical expertise could allow community hospitals to access specialists without transferring every patient.

In the near term, surgical telementoring may be the more practical version of this model.

Military Medicine

Military medicine has long been interested in remote care.

A highly specialized surgeon cannot realistically be stationed wherever an injury might occur.

Remote guidance and potentially remote robotic intervention could extend specialist expertise closer to the point of injury.

Disaster Response

Earthquakes, hurricanes, war, and other disasters can separate patients from advanced medical centers.

Portable communication systems combined with surgical technology may eventually allow specialists to support physicians working in temporary or isolated medical facilities.

Ships and Offshore Facilities

Ships, offshore platforms, research stations, and other isolated environments may be hours or days away from advanced surgical care.

These are situations where remote expertise becomes easier to understand.

Spaceflight

Space may eventually become one of the strangest applications of telesurgery.

But distance creates a major problem.

Communication between Earth and Mars can take minutes depending on the planets' locations.

A surgeon on Earth could not realistically control instruments on Mars in real time with that delay.

Long-duration space missions may therefore require a combination of locally trained crews, robotic systems, advanced decision support, and eventually greater surgical automation.

Traditional real-time telesurgery may not be enough.

Surgical Telementoring May Grow Faster Than Remote Surgery

The most important near-term development may be much less dramatic than a surgeon operating across an ocean.

It may simply be remote surgical collaboration.

An experienced surgeon can remotely help another surgeon perform a difficult procedure while the local surgeon remains physically responsible for the operation.

That model solves several problems.

A surgeon learning a new technique can receive help without requiring the expert to travel.

A specialist at a major academic center can advise a community surgeon.

A hospital adopting new surgical technology can bring experienced clinicians into early cases remotely.

Training and expertise can spread across health systems instead of staying concentrated in large medical centers.

This is easier to deploy than full remote robotic surgery because someone capable of performing the procedure is still physically beside the patient.

Telehealth Before Surgery

Not every form of telesurgery involves controlling an instrument.

Some of the most useful telehealth applications in surgical care happen before the patient ever enters an operating room.

A patient may meet with a surgeon virtually to:

• review imaging;
• discuss a diagnosis;
• obtain a second opinion;
• understand treatment options;
• discuss the risks and benefits of surgery;
• review medical history;
• or determine whether an in-person surgical evaluation is necessary.

Not every surgical consultation can be completed virtually.

A physical examination, diagnostic testing, imaging, or urgent symptoms may require an in-person visit.

But virtual consultations can eliminate unnecessary travel and help patients reach specialists who might otherwise be difficult to access.

Telehealth After Surgery

Postoperative telehealth can also be practical for selected patients.

A surgeon may be able to:

• inspect an incision by video or photograph;
• review pain levels;
• discuss medications;
• review activity restrictions;
• answer questions;
• and decide whether recovery appears to be progressing normally.

Patient selection matters.

A person with concerning symptoms should not rely on a video visit when they need an in-person examination or emergency evaluation.

Telehealth works best when clinicians are willing to say when telehealth is no longer enough.

How Is Telesurgery Regulated?

There is no single telesurgery law in the United States.

Instead, a number of regulatory systems can overlap.

These may include:

• physician licensing;
• hospital credentialing;
• medical-device regulation;
• telehealth law;
• informed consent;
• malpractice coverage;
• cybersecurity requirements;
• patient privacy requirements;
• and reimbursement rules.

Traditional telemedicine already creates legal questions about where the practice of medicine is considered to occur.

Telesurgery makes those questions even more complicated.

If a surgeon located in one state controls robotic equipment operating on a patient in another state, licensing and credentialing requirements may apply where the patient is located.

Hospitals also need clear policies around responsibility.

What happens if the network fails?

What happens if the robotic system malfunctions?

Who has final authority if the remote surgeon and local surgical team disagree?

Who is responsible for responding to an emergency?

These questions need answers before remote surgery can become ordinary hospital care.

For broader information on state rules, see our guide to telemedicine laws by state.

What Is the FDA's Role?

Robot-assisted surgical systems are medical devices regulated by the U.S. Food and Drug Administration.

Current robot-assisted systems generally allow a surgeon to control surgical instruments using computer and software technology.

The surgeon remains responsible for the operation.

The system is not simply making independent surgical decisions.

Telesurgery creates another layer of complexity because communications infrastructure becomes part of the safety equation.

Regulators and manufacturers have to consider issues such as:

• connectivity;
• latency;
• software reliability;
• network failure;
• cybersecurity;
• hardware redundancy;
• and safe failure modes.

The FDA has also participated in collaborative efforts focused on robotics, telesurgery, and surgical artificial intelligence.

That is a good indication of where the field is heading.

Cybersecurity Becomes a Patient-Safety Problem

Cybersecurity matters everywhere in healthcare.

With remote surgery, cybersecurity can become directly connected to physical patient safety.

Connected surgical systems may need protection against:

• unauthorized access;
• malware;
• ransomware;
• communications interception;
• software vulnerabilities;
• network disruption;
• and malicious commands.

That means cybersecurity cannot simply be treated as an IT issue after the surgical system is installed.

It has to be built into device design, hospital infrastructure, network architecture, and clinical risk planning.

Can Artificial Intelligence Perform Surgery?

Artificial intelligence will probably become part of the telesurgery story.

But AI assistance and autonomous surgery are not the same thing.

AI and computer vision may help surgical systems:

• recognize anatomy;
• identify surgical instruments;
• analyze surgical video;
• track procedural steps;
• improve navigation;
• flag potential abnormalities;
• and support surgical decision-making.

Those capabilities do not necessarily mean an AI system is independently performing the operation.

The more realistic path is gradual.

Surgeons may receive increasingly sophisticated assistance while remaining in control.

Certain repetitive or narrowly defined surgical tasks may become more automated.

Greater autonomy may eventually follow.

Fully autonomous surgery would create another level of clinical, ethical, technical, liability, and regulatory questions.

Is Telesurgery Available Today?

For most patients in the United States, true long-distance robotic telesurgery is not something they should expect during routine medical care today.

But many pieces of the model are already here.

Patients may encounter:

• virtual surgical consultations;
• postoperative video appointments;
• remote surgical second opinions;
• remote patient monitoring after surgery;
• surgical telementoring;
• teleproctoring;
• and robot-assisted surgery with the surgeon physically nearby.

Remote robotic surgery continues to advance through research and specialized programs.

That distinction matters.

Telesurgery is not science fiction anymore.

But it is also not yet routine everyday surgery.

The Future of Telesurgery

The question is probably no longer whether a surgeon can operate from another location.

That has already been demonstrated.

The more important questions are:

Can the network be trusted?

What happens when something fails?

Who needs to be physically beside the patient?

Who is legally responsible?

Who is licensed to provide the care?

Who pays for it?

Can hospitals afford the infrastructure?

Does it actually improve access to specialists?

And most importantly:

Are the outcomes as safe as having the surgeon physically present?

Those questions will determine whether telesurgery becomes a major part of medicine.

The technology is advancing.

But surgery has an appropriately high standard.

Being technically possible is only the beginning.

Being reliably safe enough to use every day is what matters.
