Surgical procedure capture, modelling, and editing interactive playback

An apparatus for generating surgical procedure training media, comprising:

• one or more processors;
• an image capturing component for recording three-dimensional imaging data over time of a portion of a human patient's body undergoing a surgical procedure;
• a spatial detection system for capturing an orientation of a surgical instrument relative to the human patient's body during the surgical procedure;
• a modeling component for creating, using the one or more processors, a four-dimensional model of the portion of the human patient's body based at least on the three-dimensional imaging data and the captured orientation of the surgical instrument and for defining a decision branch in the four-dimensional model and for modifying at least a portion of the three-dimensional imaging data of the human patient's body to maintain privacy of the human patient's body;
• and
• a storage component for storing the four-dimensional model and at least one alternative four-dimensional model, wherein the alternative four-dimensional model is created from recorded three-dimensional data and captured orientations of a surgical instrument during a different surgical procedure performed on a different patient.

One or more computer storage media having instructions encoded thereupon that, when executed by one or more processors, cause a computing device to perform acts comprising:

• capturing three-dimensional data over time of a portion of a human patient's body undergoing an actual open surgical procedure, the three-dimensional data being captured from at least a stereoscopic video camera or a three-dimensional camera;
• capturing visual imagery of an exposed portion of the human patient's body;
• capturing an orientation of a surgical instrument relative to the human patient's body during the actual surgical procedure;
• capturing haptic forces on the surgical instrument during the actual surgical procedure;
• creating a four-dimensional model of the portion of the human patient's body based on the three-dimensional data, the visual imagery of the exposed portion of the human patient's body, the orientation of the surgical instrument, and the haptic forces on the surgical instrument changing over time;
• and
• recolorinq at least a portion of the three-dimensional data or visual imagery of the human patient's body to maintain privacy of the human patient's body.
