As healthcare goes increasingly remote, one critical service has been largely left behind: surgery. For years, the concept of remote robotic surgery was held back by network lag times—because when dealing with the human body, a fraction of a second delay could prove deadly. But thanks to 5G technology, lag is practically gone, and investors are betting millions that telesurgery is ready to go mainstream. In this episode, we explore this medical breakthrough and pick up five essential English expressions.
⚡ 5 Key Expressions
Expression 01
Leave (someone/something) behind
To fail to progress or develop at the same speed as others. In our story, telehealth and virtual check-ups expanded quickly, but physical surgery was "left behind" because it required in-person attendance. This phrase is excellent for discussing technological advancement, career progression, or industry competition.
- "If our company doesn't adopt AI quickly, we are going to be left behind by our competitors."
- "We walked so fast that we completely left John behind."
Expression 02
Hold (someone/something) back
To prevent someone or something from moving forward, succeeding, or progressing. While it can mean physical restraint (like holding back a dog), it is most often used abstractly. The widespread adoption of telesurgery was "held back" by slow internet networks. It is also commonly used for holding back emotions or tears.
- "She was so angry she couldn't hold back her tears."
- "Lack of funding is the main issue holding the project back."
Expression 03
A fraction of a (second/inch/price)
A very small amount of something. A fraction is mathematically a part of a whole (like 1/10). When used in phrases like "a fraction of a second," it emphasizes incredibly tight margins or tiny amounts. In remote surgery, even a tiny delay (a fraction of a second) can lead to a surgical error.
- "I bought this designer jacket for a fraction of the original price."
- "She won the race by a fraction of an inch."
Expression 04
Bet on (something)
To risk money, effort, or resources on an idea or person because you strongly believe they will succeed. Investors are "betting on" telesurgery companies right now. It implies both confidence in the future and a willingness to take a risk.
- "I wouldn't bet on the weather staying sunny; look at those clouds."
- "We are betting on the new software to improve our team's efficiency."
Expression 05
Go mainstream
To transition from being a niche, unusual, or highly specialized concept into something accepted and used by the general public. Electric cars, smartwatches, and remote work have all "gone mainstream."
- "Podcasts used to be for tech geeks, but now they've completely gone mainstream."
- "Vegan diets have gone mainstream over the last decade."
🎭 The Dialogue: Cutting Edge Tech
Maya and Alex work at a health-tech investment firm. They are at their desks evaluating a new startup in the robotics space.
📍 An investment office, Tuesday morning. Maya is reviewing pitch decks on her laptop. Alex rolls his chair over.
Maya: Alex, look at this telesurgery startup. Everything else in healthcare is remote now, but surgery has obviously been left behind.
Alex: Right. The technology has existed for a while, but widespread adoption was always held back by network lag.
Maya: Exactly. When you're dealing with organs, a fraction of a second delay can literally prove deadly.
Alex: But with 5G, they've practically eliminated that lag entirely. That infrastructure changes everything.
Maya: That's exactly why venture capitalists are betting on this space so heavily right now.
Alex: If they get the cybersecurity protocols right, remote robotic surgery is definitely going to go mainstream.
Maya: Let's run the financial models on this one. It could be a massive disruption.
Alex: I'm pulling up the market projections right now.

Can you answer this?
The concept of remote robotic surgery isn't entirely new. Doctors in New York actually managed to remotely operate a robotic arm to remove the gallbladder of a patient in France. In what year did this groundbreaking transcontinental surgery happen?
- A — 1995
- B — 2001
- C — 2012
✅ Answer: B — 2001. Known as the "Lindbergh Operation" (named after the famous aviator who crossed the Atlantic), a team of surgeons in New York successfully removed the gallbladder of a 68-year-old female patient in Strasbourg, France.
📚 Bonus Vocabulary
Telesurgery (noun) — Surgery performed by a doctor who is physically far away from the patient, using robotic arms and high-speed network connections. "The hospital is investing heavily in telesurgery infrastructure."
Lag time (noun) — The delay between a user's action and the system's reaction. "In online gaming, lag time is annoying. In robotic surgery, it's life-threatening."
Disruption (noun) — A radical change in an industry, often caused by a new technology or business model that completely changes how things are done. "Streaming services caused a massive disruption in the television industry."
