A guiding apparatus for remote medical treatments includes a first pivoting link pivotally connected to a pivot shaft, a second pivoting link pivotally connected to the first pivoting link, a driver pulley member capable of fixing the first pivoting link and the second pivoting link to each other through screw fastening, a driven pulley member capable of fixing the first pivoting link to the pivot shaft through screw fastening, and a locking wire connected to the driver pulley member and the driven pulley member to transmit a rotational force from the driver pulley member to the driven pulley member. As the driver pulley member rotates, the driven pulley member rotates together, so that the fixing of the first pivoting link and the second pivoting link to each other and the fixing of the first pivoting link to the pivot shaft is accomplished simultaneously.
