Abstract
A blood vessel harvesting system, which harvests blood vessels in a state of being covered by surrounding tissue, includes a separating device and a display device. The separating device includes a rod portion that is inserted into a living body, an optically transparent taper-shaped separating portion that is disposed at a distal end part of the rod portion, an endoscope portion that is disposed inside the rod portion and captures an endoscope image of an interior of the living body via the separating portion, and an ultrasound transceiver portion that is disposed on an outer peripheral surface of the rod portion, irradiates the interior of the living body with an ultrasonic wave, and receives a reflected wave from the interior of the living body. The display device matches a scale of the endoscope image with a scale of an ultrasound image acquired by the ultrasound transceiver portion and simultaneously displays the endoscope image and the ultrasound image side by side on the display screen, and the display device disposes the endoscope image and the ultrasound image on the display screen such that a point in the endoscope image indicating a predetermined position in the living b…
