The Future of Robotic Surgery: How Ultrasonics is Revolutionizing Surgical Innovation

In the ever-evolving landscape of medical technology, robotic surgery has made tremendous strides. A particularly exciting breakthrough in this field is the miniaturization of ultrasonic devices, allowing for greater precision, reduced trauma, and improved patient outcomes. In this article, we explore the insights from Nico Fenu, co-founder of Nami Surgical, a pioneering company in ultrasonic surgical robotics, and discuss how this technology is shaping the future of healthcare.

The Journey to Ultrasonics in Surgery

Nico Fenu’s Background and Discovery of Ultrasonics

Nico Fenu, a biomedical engineer from Italy, discovered his passion for ultrasonics during his master's degree in biomedical engineering. His work on an ultrasonic biopsy needle, which reduces trauma and improves surgical accuracy, sparked his interest in the field. During his PhD at the University of Glasgow, he began exploring ways to miniaturize ultrasonic instruments to make them more effective for robotic surgery.

The Impact of Ultrasonic Technology in Surgery

Ultrasonics utilizes high-frequency sound waves to interact with tissues in unique ways. Unlike traditional surgical tools, ultrasonic devices allow for non-invasive imaging, precise cutting, and tissue modification without excessive heat or electrical energy. These advantages make them particularly useful in robotic-assisted procedures.

The Challenges and Breakthroughs of Miniaturization

The Limitations of Conventional Ultrasonic Instruments

Traditionally, ultrasonic surgical instruments are constrained by size. The physics of sound waves means that larger instruments are needed to produce the necessary frequencies for effective cutting and coagulation. This poses a challenge for robotic surgery, where instruments must be compact and maneuverable.

Nami Surgical’s Breakthrough: Miniaturization of Ultrasonic Devices

Nami Surgical, founded by Nico Fenu and Dr. Rebecca Cleary, has developed a novel approach to overcoming these limitations. Their technology modifies the structure of the transducer, enabling it to maintain efficiency even at a smaller size. This innovation allows ultrasonic devices to be used in robotic-assisted surgeries, providing surgeons with greater dexterity and precision.

The Clinical Benefits of Ultrasonics in Robotic Surgery

Enhanced Surgical Precision and Safety

Miniaturized ultrasonic devices offer several advantages:

• Reduced thermal spread: Unlike electrocautery, which generates excessive heat, ultrasonics provides controlled energy delivery, minimizing damage to surrounding tissues.
• More precise tissue dissection: The ability to finely control vibrations allows for cleaner cuts, which is crucial for delicate surgeries such as tumor resections.
• Improved coagulation: Ultrasonic instruments can cut and coagulate simultaneously, reducing blood loss and surgical time.

Shorter Hospital Stays and Faster Recovery

With increased precision and reduced trauma, patients benefit from:

• Less postoperative pain
• Lower risk of complications
• Shorter hospital stays
• Faster recovery times

The Business Journey: From Research to Commercialization

Overcoming the Challenges of Medical Device Commercialization

Bringing a medical device to market is a complex process requiring extensive research, regulatory approvals, and strategic partnerships. Fenu’s journey involved extensive market research and collaboration with industry leaders to refine the product and validate its commercial potential.

Securing Investment and Building a Team

Nami Surgical successfully secured funding through grants and private investors, raising over £3.5 million. The company has grown into a team of 15 professionals, including engineers, business strategists, and medical advisors, all working towards making ultrasonic robotic surgery a reality.

The Future of Ultrasonic Robotic Surgery

Expanding the Applications of Miniaturized Ultrasonic Devices

While the primary focus remains on surgical robotics, the miniaturization of ultrasonic technology has potential applications in:

• Non-invasive imaging
• Underwater acoustics and sonar systems
• Jet engine maintenance and repair

Commercialization Strategy and Market Entry

Nami Surgical aims to integrate its technology into existing robotic surgical platforms through strategic partnerships. By licensing its innovations to established medical device manufacturers, the company seeks to bring its technology to operating rooms worldwide by 2027.
