A new medical training instrument has been developed, which provides a means whereby microsurgery procedures performed using an optical microscope can be viewed by any number of medical students. This is accomplished by picking-up a television picture from the operating microscope and displaying the picture so the operation can be seen "live" on TV monitors at remote locations. Also the picture can be recorded on video tape for later playback for medical teaching purposes. This instrument has the principal advantage over other teaching means of microsurgery in that it can provide a three dimensional color picture so that the student sees the same view the surgeon saw as he performed the operation.
