The invention discloses a medical instrument and a supporting device thereof. The supporting device comprises racks, front connecting parts, rear connecting parts and middle connecting rods, wherein the front connecting parts and the rear connecting parts are hinged to the corresponding racks; the middle connecting rods are hinged between the front connecting parts and the corresponding rear connecting parts; the front connecting parts, the rear connecting parts, the middle connecting rods and the racks constitute parallelograms. The supporting device further comprises constant-force elastic components. The front connecting parts are provided with front connecting arms, and the rear connecting parts are provided with rear connecting arms. The first ends of the constant-force elastic components are hinged to the free ends of the corresponding front connecting arms, and angle adjusting assemblies are arranged between the second ends of the constant-force elastic components and the free ends of the rear connecting arms, so that the extension directions of the constant-force elastic components are the same. The supporting device provided by the invention is used for supporting a constant-gravity object through the constant-force elastic components, and can realize free adjustment of ascending, descending, pushing and pulling and ensure the good operation hand feeling.
