Storyboard Text

  • They were so shaky today. If only there was some sort of equipment to quantify that and show them how to improve. 
  • We need to find a way to measure the drift! That way, we will have a way to train, assess, and screen practicing surgeons. 
  • The Goose
  •  The Goose will utilize motion analysis to assess surgical skill; an electromagnetic tracking system (an IMU cased in an enclosure) will be attached with Velcro to a laparoscopic needle driver. This prototype will measure the steadiness of the surgeon's hand during suturing procedures. 
  • Tracking device will determine the position and movements of the surgeon's hand
  • Inertial Measurement Unit (IMU) *Accelerometer *Gyroscope *Magnetometer
  •  *Absolute Orientation (Euler Vector) *Absolute Orientation (Quaterion) *Angular Velocity Vector *Acceleration Vector *Magnetic Field Strength Vector *Linear Acceleration Vector *Gravity Vector *Temperature
  • Potential sensor outputs
  • Prototype will be attached to the laparoscopic needle driver via three rings protruding from the surface of the 3D-printed enclosure. These circular attachments stabilize the enclosure on the instrument. 
  • A closer look...
  • Arduino Uno will provide the connection between IMU and the power source (computer)
