Defining the future
of robotic microsurgery
Empowering the next era of surgical precision
MMI is the global leader in robotic microsurgery. Through advanced robotics and digital innovation, we’re empowering surgeons to perform complex procedures with greater precision, consistency and control – transforming the future of open surgery at the micro level.
The Symani®
Surgical System
A breakthrough robotic technology, uniquely designed for microsurgery and supermicrosurgery, that provides surgeons unmatched precision and control to restore function and quality of life.
Precision Beyond the
Limits of the Human Hand
NanoWrist® instruments feature the world’s smallest robotic wrist and replicate natural hand movements to provide the precision and freedom needed to perform delicate intraoperative tasks, including dissection and anastomosis.
Clinical Evidence
of Better Outcomes
Studies show higher anastomosis patency, reduced flap loss and significant limb-volume reduction, demonstrating strong benefits for surgeons, hospitals and patients.
- 86% of patients with upper limb lymphedema saw reduction in limb volume1
- When compared with manual surgical techniques, Symani robotic microsurgery achieved:
- 100% anastomosis patency on 0.2mm vessels, compared to 80%2
- 0% robotic anastomosis revision rate compared to a 6% revision rate3
- >50% reduction in flap loss rate and a 12% reduction in revision rate for extremity flaps3,4,5
Expanding the reach of robotic microsurgery across specialties
Explore how Symani supports complex clinical applications, from lymphedema and breast reconstruction to head & neck cancer and trauma.
