cranial navigation

An Illuminating Approach to Cranial Surgery

7D Surgical has developed the first and only FLASH Navigation System featuring Machine-Vision technology. The system solves the clinical frustrations and challenges of traditional navigation systems, allowing surgeons to perform fast, efficient, accurate, and contactless cranial surgery.

Thousands of Virtual Fiducials in a FLASH™

The FLASH™ Navigation System is the first and only Machine-Vision platform that delivers on the promise of image guided navigation. Unlike traditional image guided navigation systems that rely on time-consuming registration devices or laborious point matching techniques, FLASH™ Navigation uses only visible light for nearly instantaneous cranial registration.
7D Surgical has integrated the power of Machine-Vision technology into cranial surgery. The result is near-instant, effortless registration using the patient’s own anatomy as virtual fiducials.

cranial registration in seconds

With a single FLASH™, and in less than 30 seconds, 1,000,000 points are digitized using 7D’s advanced cranial software algorithms.

completely eliminates sponge fiducials

With the accuracy of true contactless registration, the FLASH Navigation System utilizes visible light to register directly to the skin or skull surface, eliminating the need for sponge fiducials and enabling accurate post-fossa registration.

machine-vision technology

The Machine-Vision technology is embedded in an onboard overhead surgical light, which eliminates line of sight frustrations in the operating room. The overhead light, in combination with the foot pedal control of the software, puts the surgeon in total control from start to finish.
skin registration

Contactless flash™ registration to the skin

In a Flash™, a constellation of 1,000,000 virtual fiducials are captured automatically. It’s totally contactless registration.
7D’s dual-plane reference array allows for seamless transition between facial and posterior fossa registrations.
Move beyond sponge fiducials – 7D’s virtual fiducials use the patient’s own anatomy for extremely accurate Flash™ Registrations.
skull registration

Contactless flash™ registration to the skull

Machine-Vision enables accurate posterior fossa registration by Flashing directly to the skull.
Effortlessly navigate any region by Flashing directly to the area of interest.
Because this is completely contactless registration, the entire workflow is sterile.
linked registrations

linked registrations

7D’s instantaneous linked registration technology removes the need for inefficient and time-consuming image fusion.
Advanced technology enables navigation with layered CT and MRI datasets registered directly to the patient in real-time.
Eliminate the error associated with traditional image fusion by registering directly to the patient in just seconds.

Cranial Registration Instruments

Reference Array

Rigidly fixed, multiplanar reference array that stores multiple registrations and increases tracking range.

Universal Pointer

Light, ergonomic pointer that is tracked and used to identify locations on the patient’s skull or skin.

Biopsy Guide & Needle

Tracked Guide used to track the trajectory of a biopsy needle. The biopsy needle is a beveled navigated stylet used to penetrate lesions and collect soft tissue samples.
