Revolutionising brain surgery: French start-up secures $29 million to develop microrobot

Interesting Engineering reveals in a recent article that a French start-up, Robeauté, has successfully secured 27 million euros ($29 million) in funding to develop an innovative neurosurgical microrobot that promises to transform brain surgery.

The company is working on a rice-sized device designed to navigate the brain with exceptional precision while avoiding high-risk areas. The microrobot is set to begin its first clinical trial in 2026, where it will be used to perform microbiopsies on brain tumors.

As stated on Robeauté's website, “A technology that can navigate the brain with minimal invasiveness while collecting information to help physicians better cure patients carries tremendous potential.”

Robeauté’s microrobot aims to revolutionise neurosurgery by offering a safer, more accurate alternative to traditional rigid surgical tools, such as needles and electrode holders. These conventional instruments can pose risks to vital brain functions because they move in straight lines, often limiting access to areas that control motor and cognitive functions. In some cases, tumors are considered inoperable due to these restrictions.

The microrobot is introduced into the brain through a tiny, millimeter-wide incision. It moves along curved paths through the brain's vascular network and extracellular matrix, reaching areas that were previously out of reach. Powered by rotating silicone rings, the device gently shifts tissue using micro-scale adhesion forces. Its movement is monitored in real-time via image and ultrasound sensors placed on the skull.

With the newly obtained funding, Robeauté plans to enhance its technology, aiming to create a flexible and versatile brain surgery platform. Early preclinical tests on sheep have shown promising results, with no significant complications such as hematomas.

Looking ahead, Robeauté plans to expand into the US and seek FDA approval, with hopes for an international launch by 2030.
