ViVi® Surgical Helmet 

ViVi® is both a medical device and an infection protection system. It protects both the patient and the surgeon from contamination.

You protect while being protected

Our mission is to be the first choice for healthcare professionals who seek greater protection, for themselves and for their patients, without compromising performance.

We designed ViVi® to be comfortable 

In situations where you must stay sharp and focused, the ViVi® System creates a protective barrier that feels almost invisible, allowing you to concentrate fully on what truly matters: the procedure and the patient.

The Only Patented Touchless Surgical Helmet

Activity Sensing

The ViVi® HELMET25 intelligently adapts fan speed to your level of activity through integrated motion sensors. Whether you are standing still or moving actively during surgery, the system automatically adjusts airflow to maintain optimal comfort and ventilation.

Gesture Control

Keep your hands at the patient and just nod your head twice to change the fan speed! Alternatively, motion sensing technology recognizes your physical activity level and automatically adjusts fan speed. The ViVi® HELMET25 combines motion-sensing technology with intuitive design, ensuring complete control, superior safety, and uninterrupted focus.

New Vivi® Muffle System

Designed to improve Helmet stability and balance. The new muffles are engineered to enhance internal support to help keep the helmet stable and centered on the head.

Sweat Absorption & Rapid Drying

High-performance muffle material absorb sweat and dry quickly. The new muffles make it easy to know when it is time to replace them, for consistent hygiene and comfort.

Helmet Stability

Engineered to allow natural, unrestricted movement while maintaining a secure and balanced fit — even during dynamic activity.

Cool, Quiet, and Touchless

Surgical environments can become hot and uncomfortable—especially under a full-body suit. The ViVi® HELMET 25 solves this with a patented dual-fan system that actively pushes warm air out through a filter,creating space for a continuous flow of clean, fresh air.

Thanks to smart gesture control and adaptive airflow, the system adjusts fan speed automatically as you move. No buttons, no manual switches—just smooth, silent operation.

With high air exchange and full isolation from exhaled air, ViVi® HELMET 25 helps you breathe better, stay cooler,and stay focused from start to end!

/ lightweight

There is nothing like carbon fiber (CFRP). A mere 384g (0.85 lb) is the new benchmark for a surgical helmet. You might not even notice that there is something on your head.

/ cool & comfortable

The patented 2-fan system helps to filter and remove waste air from the suit, directing it away from the patient. A high performance air intake eliminates internal recirculation of waste air.

/ perfect balance

Nothing pulls on your neck, the virtual center of mass is inside your head.

Visual Acuity is essential

The light is vital for a clear and reliable patient assessment during surgery, with ViVi® experience no more shade.

Designed for excellent performance

The high-power light maximizes performance and comfort while enhancing patient care.

Ideal for every kind of surgery

The ergonomically adjustable light gives you excellent visual access, even in the most demanding surgeries, such as MIS.

/Crystal Clear Vision

The over-the-eye placement of the light ensures optimal shadow-free illumination, excellent depth of field, perfect eye alignment, and unobstructed access to the entire visual field — providing clarity and focus exactly where you need it most.

/Highly energy efficient

The best illuminance performance and lowest battery consumption are offered by ViVi’s LED light.

ViVi® System Components

Helmet, battery, and charger are the non-sterile hardware of the system, hood and toga are sterile, single-use gowns that are designed for a perfect fit.
