About GAUSS SURGICAL

Gauss Surgical is a medical technology company that developed Triton, an AI-enabled platform for real-time monitoring of blood loss during surgery. The Triton system utilizes computer vision and machine learning, delivered via mobile devices (specifically iPads), to provide quantitative measurement of surgical and obstetric blood loss. This technology aims to improve the detection of hemorrhage and support earlier clinical intervention, addressing the historically inaccurate practice of visual estimation of blood loss in operating rooms.

The Triton system works by scanning surgical sponges and canisters containing blood, then sending these images to the cloud where image-processing algorithms estimate the amount of blood. This real-time data is then sent back to the operating room. The technology has demonstrated improvements in maternal and surgical care by enabling earlier recognition of hemorrhage, which can lead to earlier intervention, reduced unnecessary blood transfusions, and shorter hospital stays. Triton received De Novo clearance from the U.S. Food and Drug Administration (FDA) in 2014, making it the first-ever computer vision software for surgical use.

Gauss Surgical was acquired by Stryker in September 2021. Prior to the acquisition, Triton technology was adopted in approximately 30 hospitals and used on about 100,000 patients, showing a 400 percent increase in hemorrhage recognition during health system studies.

Physician Tip

For physicians, Gauss Surgical's Triton system offers a significant advancement in patient safety by providing objective, real-time blood loss data during surgery and childbirth. This allows for earlier and more accurate detection of hemorrhage, leading to timely interventions, reduced need for blood transfusions, and potentially shorter hospital stays. The mobile-delivered solution integrates seamlessly into existing operating room workflows with minimal training, reducing the burden on staff. The technology's ability to filter out non-sanguineous fluids ensures a more precise measurement of actual blood loss.

The Triton system is delivered via consumer mobile devices (iPads/iPhones), allowing for over-the-air deployment without requiring new, specialized OR hardware. The system is designed to integrate into routine care and can connect with Bluetooth scales for comprehensive blood volume calculations. Following its acquisition, opportunities exist for cross-selling within Stryker's existing product lines and tighter integration with hospital IT systems.
