World’s Smallest Surgical Robot develops by scientists in the UK

World’s smallest surgical robot develops by scientists in the UK. This robot could transform daily operations. This surgical robot developed with low-cost technology which is used in Mobile phones and Space industry. A team of 100 scientists and engineers used these technologies specially to create the 1st surgical arm to accomplish keyhole surgery.


The robot, named as Versius, mimius the human arm. This robot can be used to carry out a wide range of procedures in which a series of small incisions are made to circumvent the need for traditional open surgery. These include a wide range of laparoscopic procedure – hernia repairs, colorectal operations also prostate, ear, nose and throat surgery. Such procedure helps to reduce complications and pain after surgery and speed up recovery time for patients.

According to its maker Cambridge Medical Robotics, this surgical robot is controlled by a surgeon at a console guided by a 3D screen in the operating theatre. The robot is much easier to use then existing systems, and takes about a third of the space of current machines.

The scientists looked at the joints within the human arm, in particular the wrist, mapping how they conduct a role to allow the hand to move so precisely and flexibly. They then replicated these movements in the robot. This surgical robot is of the same size as a human arm and has four wrist joints, giving the surgeon an unmatched level of freedom to operate on the patient from whatever angle they want.

For robots to revolutionize surgery, they need to be versatile, easy to use and small so that surgical staff can move them around the operating room or in operating theaters or pack them away when they are not being used.

The company’s chief executive, Marin Frost said, “Having robots in the operating theatre is not a new idea.”  “But the problem at the moment is that they are phenomenally expensive, not only do they cost $ 2.5 million each to buy but every procedure costs an extra $3,800 using the robot and they are very large. They are also poorly utilized; they are only really used for pelvic surgery, and can’t be easily adapted to other types of surgery. In some hospitals they are only being used once every other day. ” He also said that, “Our robot has versatile, easy to use and small and its first robotic arm which is designed especially for laparoscopic surgery.”

One of the key benefits of this robot is it works like a human arm and contains technology that detects resistance to make sure the right amount of force is used when the instruments are inside the patient.

Researchers used electronics from mobile phones to help the robot “think” and process information, and gear box technology originally designed for the space industry to help it move.

Researchers said the surgical robot is set to be launched next year. The current global market for surgical robots is worth approximately $4 billion a year but this is expected to grow to $20 billion by 2024.
