British scientists have developed the world's smallest surgical robot that can change the surgical model and perform surgery on thousands of patients every day.
In a rural area of ​​the UK, a team of 100 scientists and engineers initially developed low-cost technology for the mobile phone and aerospace industries, which were later used to study robotic arms, which can be used exclusively for minimally invasive surgery. .
The robot, called "Versius", mimics the human arm and can be used in a wide range of laparoscopic procedures, including hernia repair, colorectal surgery, prostate and ear, nose and throat surgery. In these procedures, some small incisions are needed to avoid the need for traditional open surgery. This can prevent complications, relieve pain, and allow the patient to recover quickly.
The robot is controlled by a surgeon under the guidance of the 3D screen in the operating room.
The Cambridge medical robot manufacturer claims that the surgical robot has been invented and used more easily. It is only one-third the size of the existing machine, and its surgical offer is much lower than non-intelligent minimally invasive surgery.
Martin Frost, CEO of the company, said: “The idea of ​​having robots undergo surgery is not uncommon.†The tricky problem is that it is expensive, not only for each of their offers of about £2 million, but also for each additional use. It costs £3,000. Many hospitals have to give up using robots for surgery. And it is difficult for the surgical team to manipulate the specifications of the robot.
"They are not fully utilized and only come in handy when undergoing pelvic surgery, and other types of surgery are difficult to adapt. In some hospitals, they are used every other day." 
Frost said: "If you want robots to bring subversive changes to surgery, then they must be bypassed, not only convenient, but also small and exquisite. Only then can the surgeons move them freely in the operating room, and they can be collected after the surgery. The robot we invented satisfies all of these requirements. It was the first robot developed specifically for laparoscopic surgery."
"One of the great advantages of this robot is that it works like a human arm. When performing surgery in a patient's body, it can use the appropriate science to detect resistance to ensure that the surgery is in place."
“When we want to solve problems with science, we tend to return to nature,†said Luke Hares, chief technology officer at Cambridge Medical Robotics. “We got inspiration from the human arm, the greatest surgical tool ever.â€
Hares said the researchers looked at how the human arm, especially the joints on the wrist, acted and sketched how the joints carried the arm for precise and flexible movements. The researchers then applied these actions to the robot "Versius".
The traditional robotic arm is clumsy and unwieldy. There are only three joints on each wrist. The robot arm we developed is the same size as the human arm. Each wrist has four joints, which gives the surgeon an unprecedented freedom when performing surgery. a feeling of. This allows doctors to perform surgery on patients with multiple angles and versatility.
To invent this high-end, sophisticated robot, Versius's inventors used the electronic devices of mobile phones to help robots "think" and process information. At first, the transmission technology was designed for the aerospace industry and is now used to help the robot move.
"Another advantage is that the robot won't feel tired," Hares said.
The robot will be put into use next spring. As long as the surgeon has mastered the robotic control technology, it will be able to perform surgery on the patient by the end of next year.
The Cambridge Medical Robotics team says it has partnered with the UK's National Health Service and private hospitals to introduce these robots. The current global market value of surgical robots is about $4 billion per year, but it is expected to increase to $20 billion by 2024.
