Description

Technical Field

[0002] At present, FUE (follicular unit extraction) is widely used in the field of hair transplantation. It is a high-density and refined hair follicle transplantation method. In this method, doctors use simple surgical tools such as micro-hand drills, tweezers, and scalpels to extract and plant hair follicles. The specific process is to drill with a micro-hand drill first. The disadvantages caused by this method are: when doctors use micro-hand drills to drill hair follicles, blood and cell tissue will stain the drill bit and spread to other hair follicles, which is not conducive to cleaning and observation by doctors; doctors need to wipe the drill bit repeatedly to ensure the smooth operation of extracting hair follicles; when doctors use scalpel-like tools to cut the implantation position, they rely entirely on experience and feeling, which requires a high level of experience for doctors and consumes a lot of their energy; and manual cutting results in large and small cuts, which is not conducive to the patient's later recovery; when tweezers are used for implantation, doctors need to clamp the hair follicles carefully and repeatedly by hand thousands of times, which consumes a lot of their physical strength; and over time, the doctor's muscles become stiff and sore, resulting in unstable clamping and inaccurate implantation. Because the tools are simple and the operation is complicated, the efficiency of hair follicle extraction is low, the hair is difficult to clamp, the doctor is fatigued, and the implantation effect is affected.

[0030] The following will be further described with reference to the accompanying drawings:

[0031] In view of the problems encountered in the current hair transplantation process, a new system is invented to integrate the extraction and implantation functions into an electrified system, which is easy to operate, improves efficiency, reduces the workload of doctors, and improves the implantation effect. The system consists of four parts: 1. Operation part 2. Gas circuit system 3. Electrical control system 4. Human-computer interaction system.

[0032] like Figure 1 As shown,

[0033] The hair follicle transplantation equipment consists of four parts: 1. handheld operation part 2. air circuit system 3. electrical control system 4. human-computer interaction system.

[0034] As attached Figure 1 As shown, the handheld operation part is composed of a drilling handle 1-1, and planting handles 1-2-1 and 1-2-2;

[0035] like Figure 2 As shown, specifically, the drilling handle 1-1 includes a hollow microneedle 1-1-1, a built-in micromotor 1-1-2, and a button 1-1-3, which are controlled by an air circuit and a control circuit. The air circuit always maintains a negative pressure state for adsorbing cell tissues and extracting blood and water, and the circuit is used to control the rotation of the motor 1-1-2 in the handle. The motor shaft is hollow, and the hollow inner diameter of the shaft is equal to the outer diameter of the microneedle 1-1-1. The hollow microneedle 1-1-1 itself is also hollow, and the outer diameter of the pointed end is less than 1mm and exposed outside the handle for drilling, and the other end passes through the motor shaft and is directly connected to the negative pressure air circuit at the tail. There is a button 1-1-3 on the handheld drilling handle 1-1, and the motor 1-1-2 of the handle is controlled by the button to rotate and stop, and the microneedle 1-1-1 is driven to achieve drilling and extraction, and the blood and water are sucked into the storage tank 2-5 through the negative pressure air circuit at the tail of the microneedle.

[0036] like Figure 3 As shown, specifically, there are two planting handles 1-2-1 and 1-2-2, each of which is controlled by one air circuit and one control circuit. The control planting handles 1-2-1 and 1-2-2 contain ejector pins 1-2-1 / 2-3, sliders 1-2-1 / 2-2, springs 1-2-1 / 2-1, electromagnetic coils 1-2-1 / 2-4, and buttons 1-2-1 / 2-5. The ejector pins 1-2-1 / 2-3 are installed on the sliders 1-2-1 / 2-2, the springs provide the sliders with a thrust or a pull 1-2-1 / 2-1, and the electromagnetic coils 1-2-1 / 2-4 provide the sliders 1-2-1 / 2-2 with a force in the opposite direction greater than the thrust or pull of the springs 1-2-1 / 2-1. The electromagnetic coils 1-2-1 / 2-4 can be controlled to work through the buttons 1-2-1 / 2-5 on the handles, so as to control the ejector pins 1-2-1 / 2-3 to be pushed out and retracted. The negative pressure air circuit is located at the front end of the handle, and provides negative pressure when the ejector pin 1-2-1 / 2-3 is retracted, so as to absorb the hair follicle tissue.

[0037] The gas circuit system is composed of a vacuum pump 2-3, a gas distribution exhaust 2-2, a storage tank 2-5, a digital barometer 2-1, an air filter disc 2-4, and a number of gas pipes;

[0038] Specifically, the entire gas circuit system is provided with negative pressure by the vacuum pump 2-3, and connected to the gas distribution row 2-2 through the air filter disc 2-4, ensuring that the pollutants in the passing gas are isolated on the air filter disc 2-4, and at the same time, the digital barometer 2-1 is connected to the gas distribution row 2-2 to monitor the air pressure in real time. Three routes are further divided from the gas distribution row 2-2, of which two routes are respectively connected to the tail of the planting handle 1-2-1 and 1-2-2 through the electromagnetic air valves 3-11-1 and 3-11-2, which are used to control the push needle; the third route is further divided into three routes through the storage tank 2-5, and each route is respectively connected to the end of the handheld drilling handle 1-1 and the front end of the planting handle 1-2-1 and 1-2-2 through the electromagnetic clamp valves 3-10-1, 3-10-2, and 3-10-3, which are used to control the negative pressure to adsorb blood, cell tissue or hair follicle tissue.

[0039] The electrical control system consists of a mains power access port 3-9, an air switch 3-8 including a lightning surge protector, a leakage protector, a branch circuit 3-6, a 220v to 110v transformer 3-7, a switching power supply 3-3-1, 3-3-2, a power button 3-1, a main control circuit board 3-4, a motor driver 3-2, an electromagnetic air valve 3-11, an electromagnetic pinch valve 3-10, a cooling fan 3-5 and wires;

[0040] Specifically, the mains power is connected through the mains power inlet 3-9, and enters the branch circuit 3-6 through the air switch 3-8 to power the entire system. The branch circuit 3-6 has overcurrent protection and anti-common mode interference circuits, and the mains power is divided into 4 routes, 2 of which are connected to the switching power supplies 3-3-1 and 3-3-2, and 1 is connected to the main control circuit board 3-4. The 2-way switching power supplies 3-3-1 and 3-3-2 power the main control circuit and provide 2 different DC voltages for controlling the touch display screen 4-1, the host computer motherboard 4-2, the motor driver 3-2, the electromagnetic valves 3-11-1 and 3-11-2, the electromagnetic pinch valves 3-10-1, 3-10-2, 3-10-3, and the cooling fan 3-5.

[0041] After pressing the power button 3-1, the main control board 3-4 will start the human-computer interaction system and the entire system starts working.

[0042] The main control circuit 3-4 has a temperature monitoring function. When it is detected that a certain temperature has been reached, the cooling fan 3-5 will be started for heat dissipation, and the fan rotation speed will be adjusted according to the temperature.

[0043] The main control circuit 3-4 has an air pressure monitoring function. When the air pressure is lower than a certain value, the vacuum pump 2-3 automatically starts working. When the air pressure exceeds a certain value, the air compressor automatically stops working. The value can be set through the host computer control software.

[0044] The main control circuit 3-4 can monitor the insertion status of the handheld drilling handle 1-1, control the negative pressure air circuit of the handle, and control the rotation speed, rotation direction, single and continuous rotation mode, and single rotation angle of the microneedle 1-1-1 of the handle. When the doctor presses the button 1-1-3 on the handle, the command will be sent to the main control circuit 3-4, and the main control circuit 3-4 will control the start and stop of the handheld drilling handle 1-1.

[0045] The main control circuit 3-4 can monitor the insertion status of the implantation handles 1-2-1 and 1-2-2 and control the negative pressure air path of the handles. When the doctor presses the button 1-2-1 / 2-5 on the handle, the command will be sent to the main control circuit 3-4, and the main control circuit 3-4 will control the implantation handles 1-2-1 and 1-2-2 to adsorb and implant the hair follicles.

[0046] The human-computer interaction system is composed of a touch display screen 4-1, a host computer mainboard 4-2, a foot controller 4-3, and a host computer control software.

[0047] Specifically, the host computer control software is installed on the host computer mainboard 4-2. The physician operates the host computer control software through the touch screen 4-1 to view the device status, set functions, and select functions to use. After booting up, when the host computer software selects the taking and drilling functions, the handheld drilling handle 1-1 function is activated, and the circuit and gas circuit of the handle will work at this time; when the implantation function is selected on the host computer software, the circuit and gas circuit functions of the implantation handles 1-2-1 and 1-2-2 are activated. When no function is selected, the circuits and gas circuits of the handheld drilling handle 1-1, implantation handles 1-2-1, and 1-2-2 do not work, and the buttons are invalid.

[0048] The host computer control software can also display various information: date, time; system temperature, air pressure value, system working status, working times;

[0049] like Figure 4 The figure shows the electrical and gas control circuit diagram of the hair follicle implantation device provided in the embodiment of the application. The solid line is the gas connection diagram, and the arrow direction represents the air flow route. The negative pressure generated by the vacuum pump is to allow the drilling handle and the implantation handle to absorb blood and discharge it into the storage tank, and to enable the implantation handle to pick up hair follicle tissue by adsorption during implantation.

[0050] The dotted line is the circuit connection diagram, and the direction of the arrow represents the circuit control route.

[0051] The drilling handle, the planting handle 1, and the planting handle 2 are connected to the control circuit board through the bus circuit. The vacuum pump, the electromagnetic pinch valve, the electromagnetic pinch valve, and the motor driver can all be controlled by the main control circuit board.

[0052] The drill handle and the main control circuit board can communicate with each other. The main control circuit board can read the status information and key information of the drill handle, and control the motor operation of the drill handle through the motor driver; and at the same time control the electromagnetic pinch valve 1 to manage the blood suction of the drill handle;

[0053] The implant handle and the main control circuit board can communicate with each other. The main control circuit board can read the status information and key information of the drilling handle, and control the working status of the implant handle by controlling the electromagnetic coil in the implant handle; and at the same time control the electromagnetic clamp valves 2 and 3 to control the blood suction of the implant handle. Specifically, the hair follicle implantation device also includes a main frame, and all the above devices, equipment, and modules are integrated on the main frame.

[0054] The following is an explanation of the working method of this application:

[0055] Operation: When extracting hair, the doctor uses the handheld drilling handle 1-1 to extract hair follicles. The doctor first selects the hair extraction function on the upper computer software, the handle is activated, the main control circuit board detects that the doctor presses the button, and sends the corresponding drive command to the motor and the negative pressure air circuit. The motor of the handheld drilling handle drives the microneedle to rotate, and the air circuit automatically starts to inhale under the control of the main control circuit board. The doctor aims the microneedle at the hair follicle to extract hair.

[0056] Drilling operation: When drilling, the doctor performs drilling work by holding the drilling handle 1-1. The doctor first selects the drilling function on the upper computer software, the handle is activated, the motor of the handheld drilling handle drives the microneedle to rotate, and the air path automatically starts to inhale under the control of the main control circuit board. The doctor aligns the microneedle with the position where the hole needs to be drilled to drill.

[0057] Implantation: During implantation, the physician performs implantation work through the implantation handle 1-2-1 and 1-2-2. The physician first selects the implantation function on the host computer software, the handle is activated, the main control circuit board detects that the physician has pressed a button, and issues a corresponding drive command to the electromagnetic ejector and the negative pressure air circuit. The physician presses a button, the ejector retracts, and the air circuit automatically starts to inhale under the control of the main control circuit board. The physician adsorbs the prepared hair follicle tissue on the tip of the handle, aligns it with the position where implantation is required, and presses the button again, and the ejector ejects the hair follicle tissue to the predetermined position.

[0058] Technical advantages of the present invention:

[0059] When the doctor is drilling hair follicles, drilling holes, and implanting, blood, water and other liquids will be sucked into the storage tank 2-5 for storage along the tail air path of the handheld drilling handle 1-1 and the front air path system of the implanting handles 1-2-1 and 1-2-2, and will not spread to other places, which is conducive to cleaning and the doctor's observation of the effect.

[0060] When removing hair and drilling, the size does not depend on the doctor's experience and feeling, but on the diameter of the microneedle of the handheld drilling handle 1-1. The doctor only needs to align the position and drill to a fixed depth easily, which reduces the requirements for the doctor, reduces the doctor's work intensity, ensures the consistency of the wound size, and is beneficial to the patient's recovery.

[0061] During implantation, the doctor uses the implantation handle 1-2-1 or 1-2-2 to pick up the hair follicle tissue. The front air path of the implantation handle will maintain a negative pressure state, and the hair follicle tissue can be adsorbed without manual force, reducing the doctor's workload.

[0062] The system can automatically count and store the physician's sampling, drilling, and implanting operations without the need for manual recording.

[0063] The system can support two doctors to perform implantation operations at the same time, improving the efficiency of hair follicle implantation.

[0064] The air paths of the handheld drilling handle 1-1 and the implantation handles 1-2-1 and 1-2-2 of the system are independent and do not interfere with each other, and do not need to be disassembled or replaced.

[0065] The system has built-in temperature monitoring, heat dissipation and high temperature alarm functions;

[0066] The system automatically stabilizes the voltage within a certain range, and the vacuum pump does not have to work all the time;

[0067] The handheld drilling handle 1-1 and the planting handles 1-2-1 and 1-2-2 are all provided with buttons for convenient manual operation without the need for an external foot pedal.

[0068] The implant handle uses an electromagnetic push-pull slider to achieve the push-out and retraction of the ejector pin, allowing the disposable and replaceable motion mechanism and drive circuit to be physically isolated, which not only avoids biological contamination and improves medical safety, but also improves electrical safety.

[0069] This system is not limited to the use of hair collection and planting in various parts of animals and humans.

[0070] The system usage information and patient operation information will be automatically recorded in the host computer software and uploaded to the server.

[0071] The system can be connected to the Internet for remote upgrades, remote diagnosis, and remote maintenance.

[0072] The filtering device on the branch circuit 3-6 makes the power supply of the entire system more stable.
