A surgeon's tool for operating a basket device to capture and remove an object may include a controller including a piston and cylinder mechanism for selectively and securely controlling and operating a wire and a sheath of the basket device wherein the piston and the cylinder of the piston and cylinder mechanism may each be independently operated to separately actuate the basket device. The piston and cylinder controller mechanism may include a double piston and cylinder design including first and second biasing mechanisms for biasing the basket device toward a closed position and a latch mechanism for selectively securing the positions of the cylinders.
