How Surgeons Review Imaging Without Breaking Scrub

A scrubbed surgeon has three ways to look at imaging mid-procedure: break scrub and walk to the workstation, direct a circulator by voice, or control the viewer directly without touching anything. Camera-based gesture control makes the third option practical. AirTouch reads hand gestures through a standard RGB camera and sends ordinary mouse and keyboard input to the viewer, so the surgeon scrolls, zooms, and rotates from the sterile field, and the procedure keeps moving.

What does breaking scrub actually cost?

Ask any surgeon and you will hear the same story. The plan was clear at the start of the case. Then the anatomy surprised them, and the answer was on a screen ten feet away.

Leaving the sterile field means degloving, handling the mouse, then scrubbing, gowning, and gloving again. The room waits. The patient stays under anesthesia. We do not publish a minutes figure because it varies by site and by case, and your own numbers are the ones that matter. Count how often it happens in a week in your rooms. Most teams are surprised.

The quieter cost is the look that never happens. When checking the scan is expensive, surgeons check it less often and work from memory instead.

Why is asking the circulator not enough?

Verbal relay keeps the surgeon sterile, and it turns a two-second glance into a conversation. "Scroll down. More. Back one. Can you zoom in on the left? Your left." The circulator is skilled at many things, and reading the surgeon's mind about a CT stack is not always one of them.

It also ties up a person. Every minute a nurse spends driving a mouse is a minute away from the work only they can do.

How does a surgeon control the viewer without touching it?

A camera is positioned with a clear view of where the surgeon stands. AirTouch runs on the workstation that drives the display. From there the interaction is simple:

• Raise an open palm to take the cursor.

• Pinch to click, and pinch and drag to scroll a stack or rotate a volume.

• Use mapped gestures for the viewer's own keyboard shortcuts, such as window level presets, zoom, or next series.

• Lower your hand and go back to operating.

The viewer sees standard input, so there is no plugin and no integration project. It works with existing PACS clients, advanced visualization software, and browser-based viewers. The gesture and mapping guide shows how shortcuts are assigned.

What happens when other people move in the room?

Operating rooms are full of moving hands. Patented intent detection identifies the person deliberately controlling the screen and stays with them until they finish, so incidental movement from the rest of the team is filtered out in most setups. Edge cases exist. That is why we test in the room before anyone relies on it.

What should you test before adopting it?

• Your gloves. Colors and materials vary. See touchless control in the sterile operating room for how gloved tracking works.

• Your lighting. Surgical lights create harsh contrast, and some rooms dim for endoscopy. A few environments may call for a specialized camera.

• Your line of sight. Booms, drapes, and microscopes get in the way. Camera placement solves most of it.

• Your viewer's shortcuts. The more your viewer can do from the keyboard, the more a gesture can do.

Is this a medical device?

AirTouch is computer input software, in the same category as a mouse driver. It does not process or interpret clinical images, it is not a medical device, and we make no clinical outcome claims. Camera video is processed on the local workstation.

Where to start

Pick the room where breaking scrub hurts most. Book a demo and we will test against that environment with you. If you would like to try the gestures yourself first, start a free trial on any computer with a webcam.
