There is disclosed a device for orienting an object according to a given spatial orientation. The device comprises a frame and a supporting member connected to the frame and adapted for supporting at least a portion of the object. The device for orienting an object comprises a plurality of fluid actuated devices for displacing the supporting member with respect to the frame. Each of the fluid actuated devices is actuatable between a first position wherein the device has a first length and a second position wherein the device has a second length. The device for orienting comprises an actuation mechanism comprising a plurality of actuating valves for actuating the corresponding fluid actuated device wherein an actuation of at least one of the fluid actuated devices enables to displace the supporting member with respect to the frame, thereby orienting the object according to the given spatial orientation. The device for orienting may be of particular interest in the medical sector as a medical object manipulator for reaching a given target in an anatomical structure with a suitable accuracy, for example in the treatment and/or diagnosis of prostate cancer.
