British scientists develop the world's smallest surgical robots

British scientists have developed the world's smallest mobile robot, which can do routine surgery for thousands of patients.
In the village of Cambridge County, a team of 100 scientists and engineers developed a robotic arm from the mobile phone and the space industry. The robotic arm was able to perform a hole operation (equivalent to a small incision).
The robot named Versius, which can simulate human arm to do many types of laparoscopic surgery, including hernia repair, colorectal surgery, prostate and ear nose throat surgery, do surgery to cut out some small holes, so there is no need to implement traditional open Surgery. With the robot surgery after surgery less complications, pain is not so strong, the patient's recovery faster. The surgeon operates the controller, manipulating the robot using the 3D screen of the operating room to complete the operation.
In fact, surgical robots have been there, and manufacturers Cambridge Medical Robots (CambridgeMedicalRobotics) believe that the new robot is easier to use, occupying only one-third of the existing space, and non-robot eye surgery is much cheaper.
"The problem is that the current robot is quite expensive to buy a £ 2 million (about 17 million yuan) per year," said Martin Frost, the company's CEO, who said: "The introduction of robots for the operating room is not a new idea 3,000 pound (about 25,800 yuan), very high, many doctors must use the robot in the operating room.As the robot is bulky, the surgical team is difficult to use.
"Use is quite difficult, in fact only pelvic surgery can be used, there is no way to do other types of surgery in some hospitals can only use once a day.
Foster believes that if you want the robot to revolutionize the surgery, you must make the robot more practical, easier to use, reduce the size of the surgical staff can be in the mobile phone room or operating room between the easy to move, or in the It is easy to pack when not in use. "Our robot can do it, it is the first robotic arm specifically for laparoscopic surgery," says Ford.
The robot works like a human arm and can detect the resistance with technology to ensure that the robotic arm uses the appropriate effort to do the surgery, which is critical when the instrument is deep into the patient. "When science wants to solve a problem, it often learns from nature," says Luke Harris, CTO of Cambridge Medical Robotics. "Our inspiration comes from the human arm, and the human arm is the best surgical tool in history. "
Harris said that the producer observes the joints of the human arm, especially the wrist, the precise drawing, and how the parts work, how to make the arm accurate and flexible. The researchers then copied these actions on the Versius robot.
"Traditional industrial robots are very large, the wrist has three joints, our robot size and human arm almost, there are four joints, this way to give the surgeon greater freedom, unprecedented freedom, from the Any angle to surgery, more practical, more extensive coverage.
In order to create complex, cutting-edge equipment, Versius's authors use mobile electronic technology to help robots "think" and deal with information, they also used the space industry gearbox technology to help the robot move. "There is also a benefit for robots that will not be as tired as a human surgeon," Harris said.
Cambridge Medical Robotics says it has worked with some NHS and private hospitals to bring them into the robot. The current global surgical robot market annual output value of about 40 billion US dollars, before 2024 will be increased to 20 billion US dollars.
