A control assembly for manipulating the movement of an endoscopic instrument includes an endoscopic instrument mounting arrangement adapted to receive an endoscopic instrument, three driving arrangements, and three independent control elements. The mounting arrangement offers only three independent degrees of freedom of movement of an endoscopic instrument received by the arrangement, each degree of freedom of movement being about or along a respective axis. Each of the three driving arrangements are configured to drive the endoscopic instrument in only one of the degrees of freedom of movement. The three independent control elements are configured to receive user input, such that the actuation of each of the three independent control elements regulates one of three corresponding control signals, each control being a respective one of the driving arrangements independent of the other two driving arrangements in accordance with the user input.
