During surgery, doctors often need to check the patient’s scans. They can’t touch the computer without breaking sterility, so they have to ask someone else to do it for them.

Operating-room time costs $36–37 a minute1.

Moving surgical guidance from a screen to sound cut screen time from 96% to 10%2.

Four hand shapes

  1. Open hand

    Cuts. The plane follows your palm.

  3. Two index fingers

    Measures, in millimetres.

  4. Fist

    Locks the cut and lifts the piece out.

A surgical copilot that measures what you ask about.

  1. “scrub, show me the tumor relative to the portal vein”

    Closest wall-to-wall gap, measured on the segmentation

  2. “scrub, show me where the tumor is closest to a major vessel”

    Nearest of every segmented vessel, with a CT slice through the gap

  3. “scrub, measure the tumor”

    RECIST diameter, short axis and volume

  4. “scrub, compare this cut to the original plan”

    The saved plan and the new cut, run through the same engine

  5. “scrub, what are the outcomes”
