Miniaturised surgical robotic instruments

Medical Microinstruments (MMI), a developer of novel robotic solutions for unmet medical needs, has revealed its robotic platform specifically designed for open microsurgery.

The platform allows the surgeon to control two tiny articulated microinstruments that simplify reconstruction procedures after traumatic injuries as well as after tumor removal in soft tissue and bones, and offers the potential for improved surgical success rates and patient outcomes.

MMI's instruments are equipped with the smallest articulated wrist having a 3-millimeter outer diameter and tips just 150 micron in width. The wrist is the key to performing robotic microsurgery in real clinical settings and allows easy manipulation of small sutures, from 9-0 to 12-0 in size.

"Thanks to the use of advanced materials and novel microfabrication processes, we have designed the smallest articulated wrist to provide microsurgeons unique instrument dexterity and robotic precision," said Massimiliano Simi, co-founder and VP R&D.

The surgeon operates the microinstruments while sitting at the surgical bedside and looking through the operating microscope. MMI's robotic platform captures surgeon's hand movements and a scaled-down motion is imposed on the microinstruments.
