An endoscopic surgical assembly houses at least one force transmitting member that is connected to a surgical attachment supported on the endoscopic surgical assembly. The endoscopic surgical assembly includes an elongate shaft having a proximal end and a distal end configured for connection to a surgical attachment. At least one longitudinal cavity is formed in an outer surface of the elongate shaft and extends between the proximal and distal ends of the elongate shaft. The at least one longitudinal cavity is configured for disposal of the at least one force transmitting member therein such that the at least one force transmitting member is translatable relative to the elongate shaft.
