PROBLEM TO BE SOLVED: To solve a problem wherein a visual field has been heretofore secured by exclusion or elevation of surrounding internal organs hindering a surgical visual field, using forceps in performing laparoscopic or thoracoscopic surgery but the internal organs can be excluded or elevated only at points and the forceps are a fine metallic member, and there is a risk of damaging the internal organs in exclusion or elevation.SOLUTION: A transparent light-emitting balloon type internal organ exclusion/elevation implement under-laparoscope/thoracoscope is provided for making it easy to see the internal organ to be excised in performing the laparoscopic or thoracoscopic surgery by inserting a transparent elliptic balloon 1 with handles 2a, 2b into the abdominal or thoracic cavity from an insertion port of a laparoscope or thoracoscope, and injecting a physiological saline solution or the like into the balloon 1 to swell in disc shape to thereby exclude or elevate the surrounding internal organs hindering the surgical visual field. A light emitting part 3 is provided to make the balloon 1 luminous. Light is thereby transmitted through tissue to easily recognize a blood vessel in the tissue.
