A multidirectional foot controller includes a base, a first platform, a second platform, and two pedals successively stacked and assembled together. The multidirectional foot controller is activated by having the two pedals depressed simultaneously, and then controls an externally connected endoscope to move forward or backward by a first platform, or controls the endoscope to move leftward or rightward by a second platform. By having only one of the pedals depressed, the multidirectional foot controller can change the field of view of the endoscope.

1. A multidirectional foot controller, comprising: a base;two first position detecting switches, deposited at front and rear ends of the base, respectively; two second position detecting switches, deposited at left and right sides of the base, respectively;a first platform, being such installed on a top surface of the base that the first platform is allowed to move forward or backward with respect to the base and is allowed to selectively touch one of the first position detecting switches;a second platform, being pivotally installed on a top surface of the first platform that the second platform is allowed to rotate leftward or rightward with respect to the first platform, and allowed to selectively touch one of the second position detecting switches; andtwo pedals, being such deposited on a top surface of the second platform that the two pedals are tandem arranged;wherein the base has a lower housing, a fixed platform, and at least two rollers, the fixed platform being assembled to a top surface of the lower housing, the two rollers being deposited at two ends of the fixed platform, the two first position detecting switches being deposited at front and rear ends of the lower housing, the two second position detecting switches being deposited at left and right sides of the lower housing, the first platform being deposited on a top surface of the fixed platform, the first platform having a bottom surface provided with at least two roller tracks, and each of the roller tracks abutting against one said roller. 2. The multidirectional foot controller of claim 1, wherein the base further comprises a circuit board that is fixed to the lower housing and is electrically connected to the two first position detecting switches, the two second position detecting switches, and the two pedals. 3. The multidirectional foot controller of claim 1, wherein the top surface of the first platform has a first pivot portion, and a bottom surface of the second platform has a second pivot portion, in which the first and second pivot portions are pivotally combined through a bearing. 4. The multidirectional foot controller of claim 3, further comprising a torsion spring that is such mounted around the second pivot portion of the second platform, and two ends of the torsion spring are connected to the first platform and the second platform, respectively. 5. The multidirectional foot controller of claim 1, further comprising a guiding member, wherein the first platform has a lower curved groove, and the second platform has an upper curved groove, while the guiding member has a shaft, a fixed block, and an idler, in which the shaft is received in the upper curved groove of the second platform and the lower curved groove of the first platform, and the fixed block is connected to a top end of the shaft and fixed to a top surface of the second platform, while the idler is rotatably connected to a bottom end of the shaft and abuts against a wall of the lower curved groove of the first platform. 6. The multidirectional foot controller of claim 1, wherein the first platform has front and rear ends thereof provide with a front protrusion and a rear protrusion, respectively, and the first platform touches the two first position detecting switches through the front and rear protrusions. 7. The multidirectional foot controller of claim 1, wherein the second platform has left and right sides thereof provided with a left protrusion and a right protrusion, respectively, and the second platform touches the two second position detecting switches through the left and right protrusion.
