A distal arm that holds a rigid endoscope includes a multi-joint articulated arm including first to fourth distal arm portions sequentially connected from a base portion side, and these first to fourth distal arm portions are configured so as to move on a vertical plane with horizontal rotational shafts as supports. In addition, behaviors of the respective distal arm portions are linked by a linking mechanism so that the first distal arm portion and the third distal arm portion behave in parallel to each other, and the second distal arm portion and the fourth distal arm portion behave in parallel to each other.

Endoscope holding apparatus

A medical instrument holding apparatus includes a supporting mechanism, a moving mechanism, a basal portion and a counterweight. The supporting mechanism supports a medical instrument. The moving mechanism which has first and second sides, and a shaft portion located between the first and second sides. The moving mechanism supports the supporting mechanism, allowing the medical instrument and the supporting mechanism to be moved around the shaft portion. The basal portion is coupled to the shaft portion. The basal portion supports the moving mechanism, allowing the moving mechanism to rotate around the shaft portion. The counterweight is located on the second side of the moving mechanism. The counterweight generates a first rotation moment being smaller than a second rotation moment generated from the weights of the medical instrument and the supporting mechanism and acting around the shaft portion in the opposite direction to the second rotation moment.

Medical instrument holding apparatus

An endoscope is connected optically removably to a TV camera through an adapter. A plurality of fixing pins is arranged on both sides of an insertion axis of an insertion part of the endoscope. A fixing unit to fix the endoscope removably is provided at the front end of an arm unit of an endoscope holder which supports the endoscope movably. The fixing unit has a claw and a movable claw, and grips the fixing pins of the endoscope releasably between the claw and the movable claw.
