The present invention may be embodied as a method of minimally-invasive surgery ('MIS') training using a video of an MIS comprising the steps of providing a processor, a display, and a first input device. The method comprises the step of processing the video using the processor to determine a location of the first surgical tool in each of the frames, determining whether the configuration of the first input device substantially corresponds to the location of the first surgical tool in each frame of the video while the video is displayed. The present invention may be embodied as a system for MIS training. The system comprises a processor, a communication device, and a first input device in communication with the processor. The processor is programmed perform any or all of the described disclosed methods.

Method and system for automatic tool position determination for minimally-invasive surgery training

A system and method for training a person in minimally-invasive surgery ('MIS') utilizing a video of the MIS. The system comprises a processor, a display, and a first interaction device. The processor programmed to receive the video and to obtain tracking data. The tracking data may correspond to the motion of a tool controller. The tracking data may correspond to motion of a first surgical tool in the video. The processor programmed to calculate motion of the first interaction device corresponding to the tracking data, to display the video, and to cause the first interaction device to move according to the calculated motion. The method comprises receiving the video, obtaining the tracking data, calculating a motion of a first interaction device corresponding to the tracking data, displaying the video, and causing the first interaction device to move according to the calculated motion.

An apparatus for analyzing a region below one or more layers of tissue includes a force sensor, a position sensor, and a processing system. The force sensor provides a force signal representative of an amount of force applied to a portion of the one or more layers of tissue which is adjacent to the region. The position sensor provides a position signal representative of the location of the position sensor when the force is applied. The processing system coupled to the force sensor and the position sensor determines at least one property of the region based on the force signal and the position signal.

The disclosure relates to rapid informational prototypes of three-dimensional objects and systems having three or more dimensions, wherein the informational prototype includes information beyond outer physical shape, such as stress contours, thermal gradients, internal structures and elements, and elements varying with time. One preferred manner for indicating information is through the use of differently colored regions in the prototype. According to a rapid prototyping method of the present invention, a series of slices through the object or system are defined by an ordinal number, overall contour information for describing shape of the slice in an X-Y plane, slice thickness information for describing thickness of the slice in a Z direction, and slice image information for providing useful information other than the overall contour information, preferably through color images. The method further involves cutting or otherwise extracting a plurality of layers corresponding to the defined slices from stock material, such as transparent plastic, and applying corresponding slice image information to the layers either before or after they are extracted. The layers are stacked based on the ordinal numbers of the corresponding slices to form the informational prototype. A tab is preferably added to the contour information of each slice to facilitate manipulation of the individual layers as well as the completed informational prototype. A data file format is also disclosed for storing a representation of a rapid informational prototype in an information medium. The data file format generally comprises a file header for identifying the data file, a body segment for registering a plurality slice images with a plurality of slices taken through the object or system, and a plurality of slice segments for indicating an overall contour and a thickness for each of the slices.
