Abstract
A medical observation instrument has a body and an observation sleeve. The body has a grip portion, and a support portion disposed at a distal end of the grip portion. This support portion has a circular arcuate portion. The observation sleeve is made of a transparent material. The observation sleeve has a mount portion of a circular section received in and removably attached to the support portion of the body. A light emission member is received in a receiving hole formed in an inner peripheral surface of the support portion. An illumination light from the light emission member is emitted toward the mount portion of the observation sleeve, reflected by the inner peripheral surface of this mount portion, passed through a peripheral wall of a distal end portion of the observation sleeve while being reflected by inner and outer peripheral surfaces of the observation sleeve, and then output forwardly of a distal end face of the observation sleeve.
