It’s a robot invasion —
in the operating room

Telehealth evolved rapidly during the COVID-19 pandemic, with phrases like tele-triage and tele-consultants becoming household words as governments adapted policies and encouraged remote services to manage an unprecedented health emergency. At the same time, a halt in most elective surgeries worldwide highlighted a need for advancements in robotic surgeries.

Now with progress in machine learning, AI the 5G network and robotic surgery equipment, surgeons can operate on patients from across the room and across the world.


As with most technology developments, there are kinks to iron out. Since the first telesurgery in 2001, skepticism, network issues, legislative differences between countries and the high cost of robotic equipment hindered growth. After the development of 5G, however, a team in China in 2019 performed successful telerobotic spinal surgeries on 12 patients from six cities.

While both robotic surgery and telesurgery offer more precision, are less invasive and result in quicker recovery time, telesurgery also eliminates logistical issues like travel health risks and cost of travel. It also offers better access to much needed surgeries for underserved countries.

The Lancet in 2015 published a study in which researchers estimate 5 billion people lack access to necessary surgical care. The main problem with this is not only the expense of the robotic systems, but also access to high-speed internet.

Gary Guthart, CEO of Intuitive — the company that created the Da Vinci surgical robotic system, which was the first to be approved by the U.S. Food and Drug Administration — said the company is developing innovative strategies to increase the number of surgically trained clinicians in low-resource regions.

“This is an urgent problem,” he says, “because of the significant global shortage of surgeons, particularly in low-resource countries. Every year, an estimated 16.9 million people die who might otherwise be treated.”


With the need for telesurgery development at the forefront, advancements in machine learning, AI and the 5G network, the market is expected to surge to an estimated compound annual growth rate of 11.9 percent between 2022 and 2029. The growth can be attributed to things like a desire for less invasive surgeries, precision ability, a 3D surgical viewpoint and the increasing volume of surgeries worldwide. A paper published in 2020 in Elsevier estimates that there are 310 million major surgeries each year.

Further benefits include data sharing ability between institutions, remote consultations and training surgeons.

Anthony Fernando, president and CEO of Asensus Surgical, a medical devices company that focuses on digitizing the interface between surgeon and patient, believes that using AI, machine learning and adding deep-learning abilities to robotics will result in “the best possible patient outcomes independent of surgeon skill level, training, and experience. This transition of thinking and innovation is what will drive the larger digital transformation needed to enable the future of telesurgery and other future surgical improvements that we have not even imagined yet.”

Robotic-assisted surgeries have been around for nearly four decades. The first procedure was a brain biopsy in 1985, which led the way for a gallbladder removal in 1997. This robot did not have a camera, so a human assistant had to hold the endoscope. The first telesurgery – also a gallbladder removal – was four years later.

Drones help farmers grow greener

Growing demand for food is putting increasing pressure on the environment. Excess fertilizers and chemical sprays pollute waterways: In 2020, 2.66 billion metric tons of pesticides were used around the world. But drones could be the answer to transforming the way we farm, improving crop yield and limiting environmental impact.


Soil health is another area closely monitored by farmers, now aided by drone sensory data. Information captured by drones can help farmers analyze soil composition and decide where supplements are required, increasing crop yields.

Drones are a new technology allowing farmers and consultants to obtain overhead images of farm fields and land areas at greatly reduced prices over satellite and other methods,” says Randy Price, precision farming specialist at Louisiana State University Agricultural Center.

Drones can be fitted with sensors and imaging technology, and this data plays an integral role in active farming. Among other uses, the data can help farmers identify health issues with the crop, such as fungal contaminations, pest infestations or areas of growth congestion. Identifying these issues early and targeting specific locations eliminates the need to spray entire crops with pesticides — which means less toxicants in the air, soil and food supply.

But drones aren’t only used for capturing data, they’re also good workers. Beyond identifying the problem, they can also be the solution.

“Once images are obtained, spatial variability maps can be made and downloaded to sprayer drones, which will allow automatic spraying of selected areas with very little pilot attention needed — this technology is evolving rapidly and will eventually lead to effortless, precision spraying over larger areas of land in an entirely computer-controlled fashion,” Price tells KUST Review.


With any new technology, there are obstacles to overcome. The drones are equipped with 5G and send the data back to be analyzed, but connectivity issues could inhibit data collection and transmission; wind or rain can affect drone flights; governments may require clearance to use drones; and with added technology comes added costs.

Still, with the agricultural drone market expected to grow to $10.8 billion by 2028, up from $1.3 billion in 2020, these obstacles are expected to rapidly diminish.
