Intraoperative Mobile Platform

Triton™ is a mobile vision system that leverages the power of machine learning to accurately estimate intraoperative Hb loss and blood loss on sponges in real time. The Triton System™ is also the world's first iPad-based intra-operative sponge management system.

Rapid Integration with Surgical Workflow

The Triton System™ seamlessly integrates with surgical workflow and requires minimal training. Using the iPad camera, the system scans blood-containing surgical sponges that are covered in blood, counts the sponges, and sends the images to the cloud server for processing. On the server, image-processing algorithms (Gauss Feature Extraction Technology™) estimate the Hemoglobin mass loss (sHbL) contained on the sponges and send results back to the OR in <10 seconds. Triton™ features an intuitive iPad-based interface and the entire system (App & Server) is designed and certified for HIPAA compliance.

The estimated Hb Loss (g) and EBL (ml) are displayed on the screen, with Sponge Count.


Feature Extraction Technology™ (FET™)

Gauss Surgical's Feature Extraction Technology™ (FET™) resides on a remote, highly scalable, HIPAA compliant server. By design, these image processing algorithms automatically filter out the effects of non-sanguineous  components absorbed in each sponge (e.g., saline irrigation, ascites, amniotic fluid) which act as a diluent and can modify the spatial appearance of the sample.

Clinical Performance

The Triton System™ has been clinically validated to have high accuracy in sponge Hb loss estimation and sponge blood loss estimation. In addition, it has demonstrated superior accuracy and precision in estimating blood loss on sponges when compared to visual or gravimetric method. 

Mean Percent Error

12.3% per sponge [a]
14.6% per patient [b]

Estimation Bias

0.01 g per sponge [a]
3.7 g per patient [b]

95% Limits of Agreement

-1.2 to 1.2 g per sponge [a]
-15.3 to 22.7 g per patient [b]
