Robot helps a surgeon carry out world’s first long-distance heart operations

Workflow with CorPath GRX

You’re a patient about to undergo heart surgery, but the surgeon performing the procedure hasn’t turned up at the hospital and, in fact, is still 20 miles away at the time that the operation is due to be carried out. A nightmare scenario? Not at all, if it’s anything like a recently reported world’s-first procedure carried out by a surgeon in India.

Using a robot called the CorPath GRX, created by a company named Corindus, five patients were the recipients of the first remote. long-distance heart surgery. The robot was controlled using a workstation with multiple joysticks, which allowed the surgeon to control the robot in real time while getting visual feedback in the form of livestreaming video showing what it was seeing. The procedure performed was something called (PCI), in which a small structure called a stent is used to open blood vessels in the heart that have been narrowed by plaque buildup.

According to a report in The Lancet, “Five patients with single, type A coronary artery lesions treatable by PCI consented to participate. The primary endpoint was procedural success with no major adverse cardiac events (MACE) before discharge … The primary endpoint was achieved in 100% of patients. No procedural complications or adverse events occurred, and all patients were discharged the following day without MACE. The operator scores were favorable, with the operators rating the procedure as equivalent to an in-lab procedure.”

The demonstration was actually carried out last year, although it has taken until now for news to be made public, presumably to allow for the patients to be monitored over the long term to confirm that they responded well to the treatment. However, the time since then has not been wasted. Corindus has used it to perform several remote tests in the U.S. as it continues to work toward its goal of expanding telemedicine to treat patients throughout remote and under-served parts of the world.

This isn’t the first time that robots have been used in the operating room. The world’s first robot-aided operation, a brain biopsy, was carried out in 1985. Since then, robots have been used in thousands of procedures — although never across such long distances. Last year, Digital Trends wrote about an operation carried out at the University of Pennsylvania School of Medicine involving the world’s first robot-assisted spinal surgery. That complex procedure utilized cutting-edge robotic arms to remove a tumor from a 27-year-old patient’s neck, via his mouth.

To build a lifelike robotic hand, we first have to build a better robotic brain
Robot arm gripper

Our hands are like a bridge between the intentions laid out by the brain and the physical world, carrying out our wishes by letting us turn thoughts into actions. If robots are going to truly live up to their potential when it comes to interaction, it’s crucial that they therefore have some similar instrument at their disposal.

We know that roboticists are building some astonishingly intricate robot hands already. But they also need the smarts to control them -- being capable of properly gripping objects both according to their shape and their hardness or softness. You don’t want your future robot co-worker to crush your hand into gory mush when it shakes hands with you on its first day in the office.

Wyze branches out with $199 robot vacuum featuring lidar tech
wyze enters smart cleaning market with 199 robot vac vacuum

Wyze is best known for its affordable security cameras, but now the company is entering the robot vacuum cleaner market with a $199 bot that boasts enough features to compete with many of the bigger names on the market. Unlike many budget models, the Wyze Robot Vacuum uses precision lidar to navigate through the home and avoid common obstacles and pitfalls that might snare other models. Users can also set up virtual walls to keep the vacuum from running into things like pet water bowls and over stairs.

The Wyze Robot Vacuum also has schedule times for automatic cleaning of specific areas of the home. This is particularly useful for keeping high-traffic areas (like the space in front of the door) clean.

The plan to rid the world of potholes with a fleet of asphalt-spewing robots
Pothole robot

Potholes are a real nuisance when you’re driving. However, thanks to a forthcoming robot created by a U.K.-based startup, the telltale signs of what can develop into these depressions in the road, caused by wear and tear or subsidence, could be spotted earlier -- so that they are never allowed to develop into potentially hazardous potholes.

“We are building an advanced system converging robotics with A.I. technology, to help automatically identify, characterize, and measure potholes on the go, while using a mathematical model to predict the evolution of the defects found, particularly cracks,” Sebastiano Fichera, technical director for Robotiz3d, told Digital Trends. “The prediction functionality can help prioritize repair tasks, [which is] currently done based on human judgement and experience. Prediction also makes it possible for early intervention to take place, to stop cracks from evolving into potholes.”
