It also has pin depth adjustment component under pin depth adjustment component under ultrafine needle knife, the ultrafine needle knife to be adjusted including depth
Section nut 13 and the swivel nut being sleeved on the first electromagnet 3, the depth adjustment nut 13 are screwed onto on swivel nut, and rotate depth
The electromagnet 3 of adjusting nut 13 first follows swivel nut to move.
It also has needle guard seat 20 and needle guard 14, and the needle guard seat 20 is fixedly mounted on the head of shell 1,14 sets of the needle guard
On needle guard seat 20, and cover outside ultrafine needle knife 12.
It also has control unit, and described control unit includes A switches 15, B and switchs 16, power switch 17 and based on minicore
The main control board 18 of piece, be separately mounted on shell 1 one group of A switch 15, B switches 16 and power switch 17 is used to pacify
The tapping of control button is filled, and the control signal interface communication with the main control board 18 based on microchip is connected respectively,
The main control board 18 based on microchip controls the on and off of the first electromagnet 3 and the second electromagnet 7 respectively.
The needle guard seat 20 is made of sanitation-grade stainless steel material, and the needle guard 14 is made of sanitation-grade plastics.
Working method and principle：The utility model by 220 volts of external AC, is transformed to 12 volts of direct current by transformer.
After the first middle electromagnet is by 12 volts of voltages, magnetic is produced, so that the drive mandrel that permanent magnet is made is adsorbed, drive mandrel
Ultrafine needle knife is promoted to stretch out by push rod, ultrafine needle knife travels forward, and 10-4 millimeters of its movement travel can pass through depth adjustment
Nut is adjusted, while after the second electromagnet is also by 12 volts of voltages, producing magnetic absorption, travelling forward, movement travel is 2 millis
Rice, this driver element can reach two kinds of phases by operating A switches, B to switch respectively by the main control board based on microchip
The ultrafine needle knife cut mode answered.
Ultrafine needle knife cut mode one：By pressing A switches, the first electromagnet 3 is continuously past within the time of 0.6 second to return to work
Make 3 cuttings, carry out feed and withdrawing.It is internal to be controlled to reset by spring.As regulation depth of cut is 10 millimeters, simultaneously for the first time
The B magnet 2 millimeters of control withdrawings that travel forward do not exit skin 2 millimeters of positions.Second of depth of cut is 8 millimeters, moves back 8 millis
Rice.8 millimeters of third time feed, move back 10 millimeters simultaneously magnet B retreat 2 millimeters reset.Hour hands knife is exited in third time to exit completely
Skin.This is a period of motion.It is 9 millimeter second such as to adjust feed, and three feeds distance is 7 millimeters, moves back 7 millimeters.As adjusted
Feed is 8 millimeter second, and three feeds distance is 6 millimeters, moves back 6 millimeters, by that analogy.This pattern can make skin surface only have one
Individual wound, rapid feed allows human perception pain to mitigate significantly.
Ultrafine needle knife cut mode two：By pressing B switches, doctor can be individually designed according to the state of an illness and the difference at position
Single cut.B switches are pressed, the first electromagnet reciprocating cutting is once.Doctor can be according to the therapentic part of human body, and cutting is deep
Degree.Select corresponding pattern and go out knife depth.Such as apply patient and do not operated this pin weapons more than two minutes, pin weapons automatically into
Standby mode.As operation need to reopen power switch again.
The method of ultrafine needle knife operator scheme one is continuous cut mode.The skin thickness of human body about 2mm, when completing the
Once cutting withdrawing and second cutting withdrawing is completed, all keep 2mm cutter hub depth to stay in intracutaneous, make pin knife only in hypodermic layer
Cut, i.e. continuous cutting each time, for skin, equivalent to the injury caused by single cut.Ultrafine needle knife is cut
When algesiogenic position be mainly cortex, hypodermis is less sensitive to the pain produced by the cutting of pin knife, so this
Cut mode is dramatically reduced under identical cutting times, the pain brought to patient.In addition, this continuous cut mode, right
Only one of which otch for skin, greatly alleviates infection probability.The method of ultrafine needle knife operator scheme two is single cut
Pattern.This pattern, which is only used in, only need to once cut the position for reaching therapeutic effect.
Permanent needle guard seat 20 is made using sanitation-grade stainless steel material, carry out disinfection cleaning after use, using health
Disposable needle guard 12 is made in level plastic material, because plastics cost is low, the needle guard 12 directly more renewed after each use, so
It is relatively sanitary, also permanent needle guard 12 can be made using sanitation-grade stainless steel material, the cleaning that carried out disinfection after use makes again
With.
