A looming U.S. surgeon scarcity—projected to succeed in as much as 19,900 unfilled positions by 2036, per AAMC knowledge—is ready to collide with an growing older inhabitants and continuously crumbling rural healthcare infrastructure. Rural communities face the sharpest fringe of this predicament: 136 rural hospitals closed between 2010 and 2021, leaving 60% of non-metro counties missing sufficient surgical care in 2019. Proprio is among the many firms addressing this scarcity with robotics.
Advances in surgical robotics proceed apace, resulting in methods that may more and more carry out exact duties with minimal human intervention. As an illustration, researchers at Johns Hopkins and Stanford universities lately demonstrated that imitation studying—drawing on video recordings and approximate kinematics—allows robots to deal with duties like tissue manipulation, needle dealing with, and knot-tying with excessive success charges.
In the meantime, UC Berkeley’s Ken Goldberg and Intuitive Surgical’s Gary Guthart launched in 2024 an “augmented dexterity” method the place AI-driven overlays help surgeons in actual time, aiming to scale back errors and enhance total outcomes.
Within the following Q&A, Gabriel Jones, co-founder and CEO and co-founder of Proprio, invokes writer Arthur C. Clarke and gives an inside look into how the corporate envisions the function of synthetic intelligence in augmenting—fairly than changing—human experience within the working room. In September 2024, the Seattle-based firm introduced the profitable completion of 50 surgical procedures utilizing its AI-powered Paradigm platform.
Are you able to present a quick historical past of Proprio?

Jones: On the Gates Basis, I had the chance to have interaction in conversations about formidable concepts—a lot of which at the moment are real-world options. It was in these discussions that I met my co-founders, together with Dr. Sam Browd, a number one pediatric neurosurgeon, and Dr. Joshua Smith. I used to be targeted on the way forward for mind therapies on the time, aligning straight along with his experience. After we linked, we each felt a powerful chemistry and the sense that we would have liked to construct one thing collectively.
Certainly one of our early conversations passed off in Dr. Smith’s lab, the place the query was raised: “May we exchange the microscope?”
Conventional surgical microscopes have used ground-glass expertise for over a century with some developments in lens design, coatings, and digital integration which have improved their efficiency. But, regardless of these enhancements, challenges stay in attaining the precision required for complicated surgical procedures.
After that preliminary dialog, Dr. Browd turned to our colleague James Youngquist, and we started constructing a prototype—one that will permit cameras to level straight into the mind. The dura—the protecting layer surrounding the mind—posed a novel problem, because it shifted and flexed inside the cranium, complicating efforts to keep up a steady view. Addressing this complexity grew to become an thrilling drawback to resolve.
Arthur C. Clarke’s legal guidelines acknowledged, “The one method of discovering the bounds of the doable is to enterprise a bit of well past them into the not possible,” and making use of this legislation, we realized we would have liked to transcend the present.
Greater than the expertise itself, our founding staff’s motivation has all the time been to raise the usual of care worldwide—making certain that well being outcomes will not be dictated by geographic, tutorial, or socioeconomic disparities. This perception grew to become our driving drive: expertise ought to bridge inequities, not widen them. Our mission to make superior surgical options accessible globally continues to information us each day.
This dedication impressed us to push past the restrictions of conventional surgical instruments like microscopes.
We knew that changing these outdated applied sciences required rethinking the complete surgical expertise and shifting towards AI-first, data-driven options. As a staff, we believed we might design a greater expertise—one which outmoded present expertise.
Our resolution: mild area rendering. Gentle area expertise captures 3D knowledge in actual time and permits the digital camera to maneuver within the scene, very similar to digital actuality. As an alternative of counting on snapshots, e.g. X-rays, our expertise captures and renders the complete 3D area for high-fidelity visualization—very similar to a microscope however with the ability to assist information surgical selections in actual time.

How did you develop the Paradigm surgical navigation platform?
Jones: Paradigm emerged from the belief that surgical procedure depends on pre-operative photos, from instruments like computed tomography (CT) or magnetic resonance imaging (MRI) scans, used for planning, however that solely tackle a fraction of the real-time wants throughout surgical procedure.
Whereas surgical navigation has been a multi-billion-dollar business for many years, it has stalled at solely about 30% adoption in fields like backbone surgical procedure. As talked about, surgeons constantly reported the identical problem: They couldn’t see what they wanted to see, when and the way they wanted to see it, to make one of the best selections.
To resolve this, we reimagined the issue from the bottom up. Paradigm makes use of superior AI, pc imaginative and prescient, and lightweight area rendering to create a real-time, 3D digital surroundings of the surgical scene.
In contrast to conventional methods that depend on static “snapshots” of knowledge, Paradigm captures the total spectrum of reside anatomical info. This allows surgeons to maneuver by means of a dynamic, high-fidelity 3D mannequin of the affected person’s anatomy—what we name “steering,” fairly than mere navigation.
The steering goes past mapping. It constantly feeds real-time knowledge again to the surgeon, serving to them optimize decision-making within the second. It’s like upgrading from a printed map to a real-time GPS system that not solely tracks your place but in addition adapts to altering circumstances like visitors and private preferences.
By tackling the basis points of knowledge availability and person expertise, Paradigm doesn’t simply replicate the features of conventional navigation. It transcends them, addressing the wants of the 70% of surgeons who haven’t adopted navigation instruments whereas additionally creating new potentialities for the 30% who’ve. This paradigm shift basically modifications how surgical procedures are carried out, mixing expertise and human experience for outcomes which might be sooner, extra exact, and extra dependable.
What’s the quantitative impression of Proprio’s platform throughout surgical procedure?

Jones: Clarke additionally acknowledged that “Any sufficiently superior expertise is indistinguishable from magic.” The magic behind Proprio’s Paradigm platform is that it makes surgical procedure higher, sooner, and safer—and we are able to show it with knowledge.
Paradigm gives vital advantages for each surgeons and sufferers by eliminating the necessity to pause mid-surgery for scans. Along with lowering the time the affected person stays uncovered and below anesthesia, it additionally minimizes radiation publicity for each the affected person and surgical employees. We’ve discovered that this effectivity can scale back process time by as much as half-hour.
What’s extra is that each time a scan is taken within the OR, the surgeon is uncovered to radiation, and given the amount of surgical procedures they carry out it isn’t stunning — but it’s alarming — that orthopedic surgeons are 5x extra probably to develop most cancers than surgeons in different fields.
The expertise additionally enhances outcomes with unparalleled accuracy, assembly stringent FDA requirements for precision in procedures like spinal implant placement. This mixture of security, effectivity, and precision drives higher surgical outcomes and units a brand new customary of care.
Have you ever measured the Proprio system’s impact on surgical throughput or postoperative outcomes?
Jones: A research evaluating Paradigm to conventional navigation methods discovered a 50% discount in time spent on essential duties like implant placement. Whereas this particular activity accounts for roughly 20% of the overall surgical procedure time, it contributes to an total discount in process time, which is essential in minimizing working room turnover, particularly in settings the place shift modifications or staffing turnover are frequent.

After 50 accomplished procedures, what enhancements or success metrics have you ever noticed?
Jones: We’ve achieved an as much as tenfold discount in radiation publicity, which is essential for each sufferers and medical employees. This straight aligns with our dedication to prioritizing security and lowering hurt—notably in defending medical employees from long-term dangers like radiation-induced most cancers.
As an illustration, orthopedic surgeons are [several] instances extra more likely to develop most cancers than the overall inhabitants on account of extended publicity to radiation, which Paradigm straight mitigates.
Are you able to share any peer-reviewed knowledge or ongoing medical trials assessing the accuracy and security of the Proprio system?
Jones: We’re actively constructing a basis of medical proof, together with abstracts, podium shows, and peer-reviewed publications, a few of which have been featured at main conferences.
Whereas we are able to’t share particular particulars simply but, these efforts are properly underway, and we’re excited in regards to the progress being made.
Johns Hopkins researchers have educated a robotic utilizing video footage from skilled surgeons to carry out duties like suturing. What’s your take?
Jones: Know-how ought to complement, not exchange, surgeons. Robots excel at repetitive duties like suturing, however they lack the creativity and demanding problem-solving wanted for complicated, nuanced conditions.
The actual problem—and alternative—is discovering the equilibrium level the place people and expertise collaborate optimally. As an illustration, robots can free surgeons from menial duties, permitting them to concentrate on ingenious options on the level of care. The final word potential lies in addressing challenges neither people nor robots might remedy alone, creating entry to care and improvements that profit extra individuals globally.
