The 'Hands-Free' Operating Room

The "hands-free" operating room is a surgical environment powered by a robust voice interface that allows surgeons to control displays, log data, and manage logistics without touching physical peripherals. For healthcare enterprises, this technology eliminates critical cross-infection vectors while reducing costly surgical delays and automating real-time medical record keeping.

TL;DR Touching a mouse or tablet inside the sterile field is an infection vector. A robust voice interface (that understands accents, medical terms, and voices muffled by a mask) returns the surgeon's hands to the patient — and logs everything in the medical record without a finger, without an assistant searching for the file. It is already a reality in top surgical centers.

Sterility is sacred. Every time a surgeon leaves the sterile field to use a mouse and view an MRI, they must change gloves or ask an assistant (who often does not know how to operate the system).

The risk of cross-infection increases with every touch on a peripheral. And the wasted time is costly — every minute of surgery runs into thousands of reais.

Sterile Compliance

Surgical Workflow	Traditional Operating Room	Hands-Free Operating Room
Sterility Maintenance	Surgeon breaks sterile field or relies on an assistant to click screens.	Surgeon remains 100% sterile, controlling displays via voice.
Image Navigation (PACS)	Manual search, slow adjustments, and communication lag with assistants.	Instant voice commands display MRIs/CTs on designated monitors.
EHR Documentation	Post-operative typing or manual logging by a circulating nurse.	Real-time, voice-logged timestamps and clinical actions.
Supply Logistics	Manual phone calls or leaving the room to request additional materials.	Voice-activated ERP requests for automated restocking.

The operating room OS

"Gemini, show the patient's MRI on monitor 2" — image appears in seconds on the 4K display, without anyone removing their gloves.

"Gemini, time the ischemia period" — timer starts, audio alert at 60 min, automatic entry in the medical record.

"Log the suture start time" — the surgical report is composed in real time; the circulating nurse does not need to type.

"Request a 3-0 suture kit for the room" — room logistics integrated with the ERP, restocking before the scrub tech notices the supply ran out.

⚠️ Non-negotiable requirements for surgery Voice in the operating room is not Siri: (1) recognition >98% with an N95 mask and aspirator running; (2) short wake word + critical voice confirmation before any clinical action (dose, record, call); (3) fallback via pedal/hand-switch if audio fails; (4) legal framework LGPD + RDC 302/302-A ANVISA + medical technical responsible for the system. Without this, it does not go into the OR.

Hands free. Full focus on the patient. No contamination. This is not science fiction — it is reality in our pilot projects with top hospitals.

Zero Contamination Risk

Eliminate physical touchpoints like mice, keyboards, and touchscreens to maintain an absolute sterile field.

Real-Time Documentation

Dictate surgical notes and log timestamps directly into the EHR without interrupting the procedure.

Seamless PACS Integration

Call up MRIs, CT scans, and patient records instantly using natural voice commands on 4K displays.

Automated Supply Logistics

Order sutures and equipment directly from the OR, syncing automatically with ERP inventory systems.

Acoustic Assessment

We analyze the OR's unique acoustic environment, accounting for surgical aspirators and equipment noise.

PACS & EHR Integration

Our voice interface is securely integrated with your hospital's PACS/RIS and Electronic Health Records.

Custom Voice Training

The system is calibrated to recognize complex medical terminology, accents, and voices muffled by surgical masks.

60-Day Pilot Launch

Deploy the solution in a single operating room to measure time savings, sterile compliance, and team satisfaction.

Frequently Asked Questions sobre The ‘Hands-Free’ Operating Room

What is the problem with touching mice and tablets in the operating room? Touching mice and tablets within the sterile field can be a vector for infection.

How does the voice system work in the operating room? The voice system allows the surgeon to request information, such as the patient’s MRI, start timers, and record information in the medical record, all through voice commands.

What are the requirements for a voice system in an operating room? The voice system needs to have a voice recognition rate greater than 98% even with a mask and aspirator, a short wake word, voice confirmation, fallback via foot pedal, and be compliant with LGPD and RDC 302/302-A ANVISA.

What is a POC (Proof of Concept) for a ‘hands-free’ operating room? An Autenticare POC includes directional microphones, a customized wake word, integration with PACS/RIS/Medical Record, and a voice confirmation protocol, with the goal of measuring the reduction of unproductive time and team satisfaction in 60 days.
