This application provides an endoscopic device having at least one shaft with at least one portion deflectable, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes at least one first connection member and at least one second connection member. When the connection members are arranged in a straight position relative to each other, a straight-position spacing exists defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member and, when the connection members are arranged in a deflection position relative to each other, a deflection-position spacing exists which is defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member, and the deflection-position spacing in the deflection position is greater than the straight-position spacing in the straight position.
