The smallest and most accurate 3d printed biopsy robot world is unveiled this week.

The Ram 4, such as the robot is called, is of plastic, 3d-printed and is driven by air pressure. The advantage of plastic is that the robot can be used in the MRI scanner. The taking of a biopsy (a piece of tissue decreases) during breast cancer research in an MRI increases the accuracy significantly. The robot won a prestigious award at the Surgical Robotic Challenge at the International Symposium Hamlyn in London. One of the world’s most important events in the field of robotic surgery.

The ram 4 is an impulse for the entire diagnostic stage of breast cancer; the precise needle control, as well as real-time scanning using MRI and a single thin needle biopsy, and may be faster and more accurate diagnosis. Medical robotics is no longer indispensable in hospitals in the near future.

Ram 4

The ram 4 is driven by the rectilinear and curved air pressure engines. The robot is controlled with hydraulic hoses of 5 meters in length outside of the MRI scanner. The design is smaller than the previous version, so that it fits into the narrow tunnel of the MRI scanner.


Breast cancer is the most common cancer in women. By placing a needle into the breast and to navigate to the abnormal tissue (lesion), it is possible to obtain a tissue sample. After clinical analysis is a good diagnosis; This is called a biopsy.

Without Invasive Surgery

Accurate navigation of the biopsy needle is very important for fighting breast cancer and other cancers. Through the use of special needles, the tip can be very hot (thermal ablation) or very cold (cryoablation), it is possible to destroy tumor cells near the tip of the needle. Thus, cancer can be treated without invasive surgical procedures are needed.

Robotics Is The Solution

To accurately detecting and visualizing the location of abnormal tissue MRI scanners provide the solution. Accuracy can unfortunately not be fully realized as long as the needles are controlled by hand. Robotics is the solution. Not all robots can be used with MRI scanners. Robots are often made of metal, and this material is not accompanied by the strong magnetic fields of MRI scanners. Therefore, the UT made in collaboration with ZGT (Twente Hospital Group) full of plastic robot.
