Abstract: A medical port includes: a faceplate having a through-hole; an elastic member formed in a curved shape and configured to clamp and fix a living tissue between the elastic member and the faceplate; and a string-shaped member fixed at a first end to the elastic member and extending from the elastic member through the faceplate. The elastic member is configured such that extension of the string-shaped member through the faceplate in a direction opposite to the elastic member reduces an outer diameter of the curved shape of the elastic member.

Abstract: A medical system having a first insertable instrument having a first image sensor; a second insertable instrument having a second image sensor; a first arm configured to move the first insertable instrument; and a controller configured to: acquire a position and orientation of the second insertable instrument in a predetermined coordinate system; calculate a position and direction of an optical axis of the second image sensor based on the position and orientation of the second insertable instrument; acquire a position and orientation of the first insertable instrument in the predetermined coordinate system; calculate a first operation amount of the first arm to move the first image sensor such that the optical axis of the second image sensor substantially coincides with an optical axis of the first image sensor, based on the position and orientation of the first insertable instrument; and control the first arm based on the first operation amount.
