Abstract

Provided is a medical arm device that avoids interference with a surgeon. A medical arm device includes a first arm part including a tip part that supports a medical instrument such as an endoscope, and a second arm part that supports the first arm part, and includes at least two horizontal rotation axes and an inter-axis distance changing unit that changes a distance between the two horizontal rotation axes. The tip part includes a structure in which joint members corresponding to rotation axes of three degrees of freedom that determine an attitude of the medical instrument are directly connected, and a rotation axis around a longitudinal axis of the medical instrument, a yaw axis in a case where the rotation axis around the longitudinal axis is a roll axis, and a pitch axis are disposed in order from a most tip part.
