Robotic Surgery —
Demystified.
A clear, honest guide to what robotic surgery is, how the system works, and what to expect — from Dr. Supradeep Narayanaswamy.

What patients often assume
Many patients believe the robotic system operates autonomously or uses AI to make decisions during surgery. This is not accurate.
The reality
The robotic system is a precision instrument — like an advanced scalpel. It has no autonomy whatsoever. Every movement, every decision is made by me, your surgeon, in real time.
Who is really in control?
Every motion during your surgery is made by your surgeon, in real time. The system responds only to my hands.
Your surgeon is in the same operating room, just a few feet away, throughout the entire procedure.
Tap any hotspot to learn what each component does.
Where I sit throughout the operation, viewing a magnified 3D image and controlling every instrument with precise hand and foot movements.
Positioned beside you in the OR. It holds the robotic arms that carry the camera and instruments through small incisions of just 1–2 cm.
Houses the imaging system generating the high-definition, magnified 3D view used to operate — up to 10× magnification.
Large hand movements at the console are translated into very small, precise movements inside your body — with natural hand tremor filtered out automatically.
Instrument tips rotate and bend far beyond the natural range of a human wrist — reaching tight spaces deep in the pelvis or abdomen with precision that open surgery cannot easily match.
The 3D HD camera gives me a view of your anatomy that no human eye looking directly at the surgical field could ever achieve. I see more — I can do more.
Every human hand has natural micro-tremors. The robotic system filters them out automatically before they reach the instrument tip — on every single movement.
Operating from a comfortable, ergonomic console means I can maintain peak concentration and precision — even during long, complex procedures.
Open Surgery — One large incision (15–25 cm)
Robotic Surgery — Small ports (1–2 cm each)
*Ranges are general averages and vary by procedure, patient health, and surgical complexity. Consult your surgeon for personalised advice.
If I look away from the viewer or lift my hands from the controls, all instrument movement pauses instantly. The system cannot move without me actively controlling it.
An assistant surgeon, anaesthesiologist, and scrub team are present in the room for the entire operation — never remote, never absent.
Extensive safety checks occur before every case. In extremely rare instances, the OR is fully prepared to convert immediately to open surgery if ever needed.
A note from your surgeon
It enhances it.
"The robotic system is not a substitute for surgical skill. It is an extension of my hands and eyes — giving me better vision, greater reach, and finer control. Your outcome still depends entirely on human expertise, training, and judgement."
