What Actually Happens During Robotic Surgery: From Incision to Recovery

Robotic surgery tends to sound more dramatic than it actually is. The word "robotic" conjures up images of a machine operating on its own, deciding what to cut and where, while the surgeon simply watches from a distance. In reality, nothing about the procedure works that way.

Robotic surgery is a form of minimally invasive surgery in which the surgeon controls specialised instruments through a handful of small incisions. Every movement, every decision, comes from the surgeon, who sits at a console and guides the instruments using hand controls and foot pedals, while a magnified, high-definition camera shows exactly what is happening inside the body.

Understanding what actually happens, step by step, can make the idea of robotic surgery feel far less unfamiliar.

How Robotic Surgery Actually Works

• Assessment and planning: Before anything is scheduled, your surgeon reviews your medical history, examination findings, blood tests and scans to confirm whether robotic surgery suits your condition. For cancer cases, imaging helps map the exact location and extent of disease.
• General anaesthesia: Most robotic procedures are carried out under general anaesthesia, so you are asleep and unaware of the operation itself, with your vital signs monitored throughout.
• Small incisions, not one large cut: Instead of a single long incision, the surgeon works through several small ports, through which the camera and instruments are introduced. This generally means less disruption to surrounding tissue than open surgery, though it can still be a major operation.
• A magnified, three-dimensional view: The console gives the surgeon a close-up view of the surgical field, which is especially valuable when working near nerves, blood vessels or other delicate structures.
• Precise, tremor-free control: The system translates the surgeon's hand movements into fine, controlled instrument movements and filters out natural hand tremor, though the surgeon alone decides what happens next.
• The operation itself: Depending on the condition, this may involve removing diseased tissue, such as the prostate in selected prostate cancer cases, or removing a kidney tumour while preserving as much healthy tissue as possible.
• Also used in kidney transplant surgery: Beyond cancer procedures, robotic techniques are increasingly used in selected kidney transplant surgeries as well. The smaller incisions can be particularly relevant for transplant recipients, in whom wound healing is often a specific concern.
• Closure and recovery: Once the procedure is finished, the instruments are removed, the small incisions are closed, and you are moved to recovery, where the anaesthesia team monitors you as you wake up.

Is Robotic Surgery Painful Compared With Open Surgery?

Robotic surgery can still cause discomfort, since it remains surgery, but smaller incisions often mean less wound-related pain than with open procedures. Pain varies from person to person, and pain relief is provided to keep it manageable during the first few days.

How Long Does Recovery Take?

There is no single answer, since recovery depends heavily on the procedure itself and your overall health.

In the first few days, tiredness and soreness are common, and short walks are usually encouraged as soon as it is safe. Over the following weeks, energy gradually returns, though heavier activity, driving and exercise are typically reintroduced slowly, on your surgeon's advice. Some procedures, particularly certain prostate cancer surgeries, involve a longer recovery for functions like urinary control, which can take extra time and sometimes benefit from rehabilitation.

Is Robotic Surgery Right for Everyone?

Not necessarily. Suitability depends on the type and stage of disease, the location and size of any tumour, previous surgeries, your general health and the experience of the surgical team. 

In some cases, conventional laparoscopic or open surgery remains the better option, which is exactly why this decision should always follow a proper consultation rather than an assumption that newer technology is automatically the superior choice.

Questions to Ask Before Deciding

Robotic surgery is not a machine replacing the surgeon. It is a tool that allows an experienced surgeon to operate with greater precision, a clearer view and smaller incisions, in cases where this approach genuinely suits the patient.
