A few years ago, the idea of a robot assisting in a life-saving surgery felt like science fiction. Today, it is fast becoming the gold standard across specialities, from cancer and cardiac care to orthopaedics and neurosurgery.
At the forefront of this transformation, experts at Kauvery Hospital are leveraging robotic technology to push the boundaries of precision, safety, and recovery. But what does robotic surgery really mean for patients? Is it about replacing the surgeon or empowering them?
For years, futurists have suggested that surgery would be one of the first fields to be overtaken by automation. Yet, even as robotic and AI-driven technologies advance at a remarkable pace, the surgeon remains firmly at the centre of every procedure. Rather than replacing human expertise, robotics is redefining it - enhancing a surgeon’s capabilities with tools that deliver far greater precision, control, and confidence in the operating room.
In this deep dive, four leading specialists across oncology, cardiology, general surgery, and orthopaedics come together to decode how robotics is not just enhancing surgical outcomes, but fundamentally redefining the way modern medicine operates.
Sharper Precision, Better Outcomes
“In oncology, with up to tenfold magnification, we can identify and remove even the tiniest tumours with exceptional precision, while preserving surrounding nerves and other vital organs,” says Dr. Sujay Susikar, Senior Consultant - Surgical Oncologist and Robotic Surgeon. “This leads to far fewer post-operative complications.”
Dr. Joyner Abraham, Consultant - Minimal Access Surgery, agrees: “In patients with prior surgeries, robotics allows precise removal of scar tissue (adhesiolysis), as well as safe dissection in distorted anatomy. This enables minimally invasive solutions in cases where open surgery was once the only option. Beyond this, even in deep pelvic and upper abdominal procedures, robotics has significantly improved precision, particularly in situations requiring preservation of critical structures.”
Dr. Mukunth, Senior Consultant, Orthopaedics, adds: “Robotic technology plays a vital role in modern knee joint replacement by bringing exceptional precision and safety to the procedure. It guides surgeons on the exact millimetre of bone to be removed, ensuring optimal implant fit while minimising unnecessary tissue damage. The latest fourth-generation systems further enhance safety by indicating critical boundaries, helping avoid injury to arteries, blood vessels, and nerves.”
In spine surgery, where precision is paramount, even a millimetre can define outcomes. The spine, surrounded by critical nerves and blood vessels, leaves little room for error. At Kauvery Hospital, advancements such as robotic-assisted and navigation-enabled technologies are transforming how these complexities are managed. Systems like the O-ARM 3D imaging platform provide real-time, high-definition visualisation of the patient’s anatomy during surgery, enabling surgeons to navigate with exceptional accuracy. This level of precision is particularly crucial in the placement of implants such as pedicle screws, significantly enhancing both safety and surgical outcomes.
Minimally Invasive by Design
For patients, one of the most visible benefits is minimal to no scarring, a hallmark of minimally invasive procedures. “Robotic surgery is also minimally invasive, avoiding the need for large bone cuts or rib splitting. As a result, patients experience faster recovery, less pain, and clear cosmetic benefits due to minimal or no visible scarring. At Kauvery Hospital, we have successfully performed bypass surgeries without opening the chest,” says Dr Arunkumar Krishnasamy, Senior Consultant Cardiothoracic Surgery, Kauvery Hospital Alwarpet.
“Robotic surgery requires only small incisions while providing greater access to cancer sites. In one case, we operated on a young patient and were able to remove cancers in both the thyroid and breast through a single incision, in one sitting. The patient was discharged on the second day after surgery, with no visible scarring,” Dr. Sujay Susikar points out.
Dr. Joyner Abraham echoes this view: “Most importantly, procedures that once required large open incisions - such as complex incisional hernia repairs and component separation - are now routinely performed robotically. In essence, robotics allows us to bring the finesse of open surgery into a minimally invasive platform. Two areas have been particularly transformative: complex incisional hernias and abdominal wall reconstruction, which were traditionally managed through open surgeries with significant morbidity.”
Faster Recovery, Standardised Care
Faster recovery is another major advantage driven by improved consistency in care. Robotics is helping standardise the quality of care. In conventional surgery, outcomes can vary depending on an individual surgeon’s style. With robotics, however, that variation is reduced, enabling a more consistent standard of care. In robot-assisted procedures, it is far less likely to miss steps in established surgical protocols.
Dr. Sujay Susikar adds that faster recovery allows cancer patients to begin adjuvant therapies such as radiation and chemotherapy much sooner. “With traditional surgery, patients often have to wait for months for the body to recover. However, with robotic-assisted procedures, they can start adjuvant treatment within two weeks,” he says.
Experts also emphasise the importance of dedicated teams and standardised perioperative protocols in supporting optimal recovery.
The Road Ahead
The evolution of robotic technologies continues to empower surgeons, making procedures safer, more efficient, and increasingly tailored to individual patients. One exciting potential is robotic telesurgery, where procedures are performed remotely. While it is already possible today, it is set to become a standard practice in the years to come.
At Kauvery Hospital, robotic surgery is not merely an addition. It is transforming day-to-day clinical practice, enabling the conversion of traditionally open, high-morbidity procedures into precise, minimally invasive surgeries with improved outcomes and patient experience. The hospital also fosters a strong academic and training environment, ensuring continuous innovation and evolution in surgical care.
