Op.n just went from navigation-only to robotic-assisted spine surgery

A navigation platform just became a robot, on paper.
Spineart and eCential Robotics announced FDA 510(k) clearance on August 26, 2026, for the PERLA TL application to run on eCential's Op.n platform in robotic-assisted mode.
Until this clearance, PERLA and Op.n were compatible only in navigation mode.
Navigation tracks instruments and implants against a patient's imaging while the surgeon's hands do the work.
Robotic-assisted mode adds a robotic arm that carries out part of the surgical plan.
The clearance covers the PERLA TL Open and MIS pedicle screw systems, in both open and minimally invasive spine procedures.
What actually changed
The hardware is not new. Op.n has been on the market as a navigation platform.
What changed is the software layer. PERLA TL is now authorized to send instructions to Op.n's robotic arm, not just display them on a screen.
That is the difference between a system that shows a surgeon where to go and one that helps steer the instrument there.
What "robotic-assisted" means, and doesn't
FDA's own language on this device category is worth repeating every time a "surgical robot" headline runs.
Robotically-assisted surgical devices are a type of computer-assisted surgical system that lets a surgeon control instruments through small incisions using computer and software technology.
In FDA's own framing, the device is not actually a robot, because it cannot perform surgery without direct human control.
The Op.n arm now has clearance to execute part of a surgeon's plan under that same standard: assisted, not autonomous.

The app-layer strategy
Building a dedicated surgical robot from scratch takes years and its own hardware clearance.
Plugging planning software into an already-cleared navigation platform is a shorter path.
Op.n was already on the market for navigation. This clearance did not require a new robot. It required a new authorization for existing hardware to act rather than just track.
For an implant maker, that shifts robotics strategy away from manufacturing an arm and toward writing the software that tells someone else's arm what to do.
