Head Mounted 3D Digital Vision System
 
A three-dimensional (3D) digital vision system incorporates a head mounted display (HMD) that allows the surgeon to focus on the surgical field, supporting a broad range of complex surgical procedures.

The Viking Endosite 3Di is an advanced vision system used by surgeons for complex minimally invasive surgery (MIS), with an initial focus on applications in urology, gynecology, bariatrics, and general surgery. The proprietary Infomatix system enables critical clinical images to be viewed in the HMD, and a voice-activated system allows the surgeon to view secondary video and existing diagnostic reference images without leaving the patient. The Viking Endosite 3Di is manufactured by Viking Systems (San Diego, CA, USA).
