The needle hub 20 is made of a sanitary stainless steel material, and the needle hub 14 is made of a sanitary plastic material.

The working mode and principle are as follows: the invention converts 220V of external alternating current into 12V of direct current through the transformer. The first electromagnet in the middle generates magnetism after passing through 12 volts, thereby absorbing the transmission core shaft made of the permanent magnet, the transmission core shaft pushes the ultramicro needle knife to stretch out through the push rod, the ultramicro needle knife moves forwards, the movement stroke of the transmission core shaft is 10-4 mm, the transmission core shaft can be adjusted through the depth adjusting nut, meanwhile, the second electromagnet also generates magnetism after passing through 12 volts, and the transmission core shaft moves forwards, the movement stroke is 2mm, and the driving unit can achieve two corresponding ultramicro needle knife cutting modes through a main control circuit board based on a microchip by respectively operating the switch A and the switch B.

Cutting mode one of the ultra-micro needle knife: by pressing the switch a, the first electromagnet 3 is continuously reciprocated for 3 times of cutting in 0.6 seconds, and feeding and retracting are performed. The inside is reset by the spring control. If the first time the depth of feed is adjusted to 10 mm, the B magnet moves forward by 2mm to control the retracting knife not to withdraw from the skin at the position of 2 mm. The depth of the second feed is 8 mm and the depth of the second feed is 8 mm. The third feeding is 8 mm and 10 mm and the magnet B is 2mm back for resetting. The needle knife completely withdrawn from the skin at the third withdrawal. This is a movement period. If the feeding is adjusted to 9 mm, the feeding distance is 7 mm for three times, and the feeding is retracted by 7 mm. If the feeding is adjusted to be 8 mm second, the feeding distance for three times is 6 mm, the feeding is retracted by 6 mm, and so on. The mode can lead the skin surface to have only one wound, and the knife is rapidly fed, so that the pain perceived by the human body is greatly reduced.

And a second cutting mode of the ultra-micro needle knife: by pressing the switch B, a doctor can independently design a single cut according to different conditions and positions. The switch B is pressed down, and the first electromagnet cuts reciprocally once. The doctor can cut the depth according to the treatment part of the human body. And selecting a corresponding mode and a cutter outlet depth. If the operator does not operate the needle knife gun for more than two minutes, the needle knife gun automatically enters a standby mode. If the power switch is required to be turned on again during the operation again.

One method of operating mode one of the nanoneedle blade is a continuous cutting mode. The skin thickness of human body is about 2mm, when accomplishing the first time cutting and moving back the sword and accomplish the second time cutting and moving back the sword, all keep 2 mm's cutter body degree of depth to stay in skin, make the needle sword cut only in subcutaneous layer, once cut in succession promptly, to skin, be equivalent to the injury that single cutting caused. The pain generated during cutting of the ultra-micro needle knife is mainly the cortex, and subcutaneous tissue is insensitive to the pain generated during cutting of the needle knife, so that the pain brought to a patient under the same cutting times is greatly relieved by the cutting mode. In addition, the continuous cutting mode has only one incision for the skin, so that the infection probability is greatly reduced. The method of operating mode two of the ultramicroneedle knife is a single cut mode. This mode is used only in the area where only one cut is needed to achieve the therapeutic effect.

The sanitary stainless steel material is adopted to manufacture the permanent needle sleeve seat 20, the sanitary plastic material is adopted to manufacture the disposable needle sleeve 12 after the use, and the plastic material is low in cost, so that the disposable needle sleeve 12 can be directly replaced after each use, the disposable needle sleeve 12 is more sanitary, the sanitary stainless steel material can be adopted to manufacture the permanent needle sleeve 12, and the disposable needle sleeve 12 can be used again after the use.
