Haptic Feedback in the Da Vinci Surgical System

The Da Vinci Surgical System is a robot built by Intuitive Surgical. After being approved for use by the FDA in 2000, it has been adopted by surgeons performing a wide range of minimally invasive procedures, including prostatectomies, cardiac valve repair, and gynecologic procedures. As of June 30, 2014, approximately 3,100 Da Vinci robots were installed worldwide, with each unit costing roughly $2 million. The primary innovation of the Da Vinci system is the surgeon’s console: an immersive visualization system that takes an ordinary laparoscopic image and projects it to a binocular display, enhancing the dexterity with which a surgeon can perform several procedures. For the patient, the Da Vinci system typically provides a reduced amount of pain and blood loss, frequently resulting in a shorter hospital stay and faster recovery period.

Earlier this year, Oculus released the final consumer version of the Oculus Rift, after much anticipation following their historic Kickstarter campaign and subsequent acquisition by Facebook. However, with Oculus currently losing the VR war to the more expensive HTC Vive, Oculus now seems to be planning to beat other players in the VR space with advanced haptics. Researchers at Oculus are currently working on a project called HapticWave, which uses a circular metal plate placed on top  of a ring of electromagnetic actuators to communicate precise haptic feedback to your hand, when placed on the plate.
