sixthly, repeating the steps until one needle preparation box (19) is emptied, controlling a rotary motor in the first base (1) to start and drive the needle preparation rotary table (5) to rotate by the controller, and rotating the other needle preparation box (19) to the position below the adsorption mechanism to prepare for adsorption;
seventhly, repeating the steps from the step (c) to the step (c) until all the needle preparation boxes (19) are emptied.
6. The surgical needle delivery method as set forth in claim 5, wherein: in the third step, when the distance between the bottom end of the adsorption mechanism and the surgical needle is far enough to cause that the adsorption mechanism can not adsorb the surgical needle, the controller controls the cylinder (15) with the guide rod to be started and drives the adsorption mechanism to be pressed downwards through the connecting plate (13) until the surgical needle is adsorbed smoothly.
