Documented safety, performance, and reliability, supported by over 32,000 neurosurgical procedures worldwide.

Safety and Trusted Performance

Phasor Health’s products are backed by peer-reviewed data, real-world patient outcomes, and an obsessive commitment to product innovation and improvement. Across 32,000 (as of end-2026) documented procedures, Phasor drills have maintained an unparalleled anti-plunging safety record with proper use, establishing a new benchmark for reliability in cranial and spine access. This record is built on verified clinical experience across 300+ hospitals and five continents, used by neurosurgeons, neurosurgery residents, physician assistants, nurse practitioners, and other credentialed practitioners. Each device is FDA-cleared, and manufactured in the United States under a careful Quality Management System.

Selected Peer-Reviewed Publications

Independent studies have evaluated and cited Phasor technology in peer-reviewed journals, confirming its clinical feasibility and procedural safety in various applications, with selected studies as listed here:

Clinical Highlights

Phasor’s record of safety and reliability is reinforced through mechanical testing, user feedback, and documented clinical use.

Core validation metrics:

Est. 32,000 procedures worldwide with Zero reported plunging incidents utilizing the drill stop extension
50 lb anti-plunge stopper (for drill stop extension and optional secondary drill stop) verification — exceeds applied surgical force requirements
100% batch inspection and torque stability testing for every production line
Utilized successfully for EVDs, ICP monitors, SEEG, LITT, biopsy, spine, and more
Predicate device reference: Since Phasor Drill is the original electric drill in the modern era, it serves as a predicate for others trying to do the same (which helps validate the need for such products, despite Phasor’s significant experience of a decade of development)

Unlike so-called self-stopping drills that can cease rotation yet still be physically pushed intracranially (see Vogel et al.), the Phasor system’s mechanically tested anti-plunge mechanism on its drill stop extension and secondary drill stops has produced Zero reported plunges with proper clinical use: an unparalleled record to date in neurosurgery.

Regulatory and Quality Validation

Phasor devices meet stringent U.S. regulatory standards allowing them to be used for patient care, and often strive to “exceed minimum requirements” with a dedicated Quality Management System (QMS).

Performance Benchmarks by Application

Cranial Access Kits

Anti-plunge protection validated to 50 lb axial load
10X anti-plunging stopper strength (for drill stop extension and optional secondary drill stops) vs. conventional stoppers
Potential reduction in contamination risk vs. reprocessed tools

LITT, SEEG, and Biopsy Drill Systems

Targeting Trajectory deviation < 1.0 mm under robotic guidance
Stable torque and power through cortical and cancellous bone
Consistent hole geometry for laser and electrode access

Phasor EVAC™ (Comparable to SEPS™)

Typically significant cost savings (as Phasor self-manufactures in the United States, effectively eliminating the middle-person company and associated higher price) – at times offering less than half the price (!)
Additional port on Bolt for aspiration, without piercing integrity of the closed system otherwise;
MRI-conditional (allowing capability to image the titanium Bolt in typical MRI settings)
