2114018 9302613 PCTABS00019 An actuator (2) is used for actuating an auxiliary endoscopic device, such as an irrigation syringe (4), a pronged forcep (98), or a stone-capturing basket (86). The auxiliary endoscopic device has a stationary portion (46) and a movable portion (62). The actuator includes a foot pedal assembly (6) having a movable part (14), a stationary part (12), a housing (8) and a coaxial cable (10). The coaxial cable includes an inner wire (30) and an outer tube (22) fixed at its ends (24, 26) to the movable part (14) of the foot pedal assembly (6) and to the housing (8). The stationary portion (46) of the auxiliary device is secured to the housing while the movable portion (62) is connected to one end of the wire, the other end of the wire being connected to the stationary part (12) of the foot pedal assembly. Thus, the foot pedal assembly is used to operate the auxiliary device while freeing the hands of the operator to operate the endoscope.
