Description

[Technical Field]

[0001] The present invention relates to the field of autologous hair follicle transplantation devices, and more particularly to a minimally invasive autologous scalp hair follicle transplantation system used to transplant scalp hair follicles into areas where hair loss has already occurred. [Background technology]

[0002] Traditional autologous hair transplant surgery includes FUT (Follicular Unit Transplant), also known as the strip technique. In this procedure, a surgeon removes a strip of scalp skin from the back of the head in an area with good hair growth, divides the strip of skin into individual follicular unit grafts, and carefully removes excess fibrous and fatty tissue using a binocular stereomicroscope, while taking care to minimize damage to the hair follicle cells used for transplantation. The surgeon then inserts a tiny scalpel or thin needle into the transplant area and transplants the hair follicles at a predetermined density and pattern. However, this type of hair transplant surgery requires careful postoperative care because the scalp is removed in a strip, leaving a large wound and requiring suturing of the excised area.

[0003] The new autologous hair transplant procedure is called FUE (Follicular Unit Excision), a new minimally invasive procedure. Under local anesthesia, the surgeon uses a special punching device, such as a 0.8-0.9mm diameter punch blade, to extract single hair follicles containing one to four hairs from the scalp at the back of the head. The surgeon then uses a tiny scalpel or fine needle to insert the needle into the transplant area and transplant the single hair follicles containing one to four hairs at a predetermined density and pattern. The same transplantation method is repeated to create a realistic hair pattern. This conventional surgical method not only efficiently controls the number of hair follicles, but also significantly reduces the size of the surgical incision and postoperative recovery time, thereby increasing the success rate of hair transplant surgery.

[0004] However, conventional devices used in surgeries to extract hair follicle units are divided into multiple independent devices, and surgeons do not always use just one device during surgery. Because the surgeon must always operate switches on the hair harvesting devices with his or her fingers, this can adversely affect the accuracy of the surgery. Therefore, there has been a demand for a minimally invasive autologous scalp hair follicle transplantation system that allows surgeons to use just one device to harvest hair follicles, incise the transplant site, collect scalp tissue from the excised area, and transplant the hair follicles into the transplant site, all while controlling the on / off operation of the device with a pedal. Summary of the Invention [Problem to be solved by the invention]

[0005] The objective of this invention is to provide a minimally invasive autologous scalp hair follicle transplantation system that is designed with a main controller, a vacuum suction pre-buffer, a hair harvesting device, and a control switch, which can perform all hair transplant surgery with a single unit, and which can control the on / off of the device with a foot switch, allowing for accurate and rapid hair transplant surgery.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be described in more detail below based on the following embodiments, but the present invention is not limited to these embodiments.

[0017] Please refer to Figure 1. As shown in FIG. 1, a minimally invasive autologous scalp hair follicle transplantation system according to one embodiment of the present invention includes a main controller 10, a vacuum suction pre-buffer 20, a hair harvester 30, a hair implanter 40, and a number of control switches 50, 50'.

[0018] Please refer to Figures 1 and 2. 1 and 2, the main controller 10 includes a main body 11 containing a hair harvester main controller 12, a vacuum device 13, a compressor 14, and a power supply system 15. The hair harvester main controller 12 is connected to the hair harvester 30 via an electric wire 121 and controls the on / off and rotation speed of the motor in the hair harvester 30. The vacuum device 13 may be a conventional vacuum pump, which is connected to the vacuum suction pre-buffer 20 via a vacuum tube 131 to generate a negative pressure in the vacuum suction pre-buffer 20 and apply a negative pressure to the hair harvester 30 and the hair implantation device 40, which are connected to the vacuum suction pre-buffer 20. The compressor 14 is a conventional device, which may be a small air compressor with an air storage tube 141, which is electrically connected to the hair harvesting device main controller 12 and directly communicates with the hair harvesting device 40 via the second hair harvesting device tube 42, and supplies the driving air required when the hair harvesting device 40 performs hair transplantation (hair follicle transplantation). The power supply device 15 is electrically connected to the above-mentioned hair harvesting device main controller 12, negative pressure device 13, compressor 14, and hair harvesting device 30, respectively, and supplies the power required for the system.

[0019] When the vacuum suction pre-buffer 20 is connected to the hair harvesting device 30 and the hair implanting device 40 and the negative pressure device 13 is activated, negative pressure is generated in the vacuum suction pre-buffer 20, which generates negative pressure in the hair harvesting device 30 and the hair implanting device 40 that are connected to the vacuum suction pre-buffer 20, and a suction action occurs. The vacuum suction pre-buffer 20 has a flask 21 for sucking scalp tissue. When the hair harvesting device 30 cuts scalp tissue at the hair implantation site from the scalp, the cut scalp tissue is sucked into the flask 21 by negative pressure. When a hair follicle transplantation operation is performed using the hair implanting device 40, the hair follicle is positioned in the hair implanting device 40 by suction by negative pressure, and the subsequent hair implantation operation is performed.

[0020] The hair harvesting device 30 is a motor-driven, electric hair follicle harvesting device that can be handheld by a doctor to perform minimally invasive scalp removal surgery of hair follicles and scalp tissue. The hair harvesting device 30 is connected to the hair harvesting device main controller 12 via the above-mentioned electric wire 121, and the hair harvesting device main controller 12 controls the motor power of the hair harvesting device 30 to remove hair follicles from the scalp and transplant them using the hair transplanting device 40. The rear end of the hair harvesting device 30 is connected to the flask 21 of the above-mentioned vacuum suction pre-buffer 20 via the hair harvesting device tube 31. During hair transplant surgery, the hair harvesting device 30 cuts scalp tissue from the transplant site and uses negative pressure to suck the cut scalp tissue into the flask 21.

[0021] The hair implantation device 40 is a pneumatic hair implantation device that implants a single hair follicle unit into the scalp. A surgeon holds the device and performs the hair follicle implantation operation, implanting the hair follicle into the selected location on the scalp. Unlike conventional manual mechanical hair implanters, the pneumatic hair implantation device allows for high-precision and rapid transplantation. The hair implantation device 40 communicates with the vacuum suction pre-buffer 20 via a first hair implantation tube 41. Before preparation for hair implantation, the hair follicle is sucked by negative pressure and positioned within the hair implantation device 40. The hair implantation device 40 also communicates with a compressor 14 via a second hair implantation tube 42. When air is delivered, the positioned hair follicle is pushed from within the hair implantation device 40 to the implantation location on the scalp.

[0022] These control switches 50, 50' are electrically connected to the hair harvesting device main controller 12, and include a control switch 50 for correspondingly controlling the hair harvesting device 30 and another control switch 50' for correspondingly controlling the hair implantation device 40. When the signals generated by each control switch 50, 50' reach the hair harvesting device main controller 12, the hair harvesting device main controller 12 controls the on / off of the motor of the hair harvesting device 30, and may also control the compressor 14 or the electromagnetic pinch valve 16 described below. This allows the doctor to control the operation of the hair harvesting device 30 and the hair implantation device 40, respectively. The control switches 50, 50' are preferably pedal switches 51, which the doctor can control by stepping on the pedal with his / her foot. When the doctor performs the hair follicle or scalp tissue removal surgery and the hair follicle transplant surgery, the pedal switch 51 controls the operation of the hair harvesting device 30 and the hair implantation device 40. In this way, unlike the prior art that requires manual key operation, the present invention allows the surgeon to use both hands during surgery, thereby improving convenience and accuracy during surgery.

[0023] Referring again to FIG. As shown in FIG. 1, the main controller 10 preferably includes an electromagnetic pinch valve 16. The electromagnetic pinch valve 16 is disposed in the vacuum tube 131 and electrically connected to the hair harvesting device main controller 12 or the control switches 50 and 50'. When the vacuum device 13 is activated, the electromagnetic pinch valve 16 opens the vacuum tube 131, generating a vacuum suction effect in the hair harvesting device 30 or the hair implanting device 40. Conversely, when the electromagnetic pinch valve 16 is controlled to close the vacuum tube 131, the hair harvesting device 30 or the hair implanting device 40 stops its vacuum suction action. Specifically, when the electromagnetic pinch valve 16 is opened, a vacuum is generated in the hair harvesting device 30, and the excised scalp tissue is sucked into the flask 21. Conversely, when the electromagnetic pinch valve 16 is turned on, the vacuum tube 131 is closed, and the hair harvesting device 30 stops its vacuum state. For example, when the electromagnetic pinch valve 16 is opened, a negative pressure is generated in the hair implantation device 40, which sucks up the hair follicles and positions them at the front end of the hair implantation device 40. Conversely, when the electromagnetic pinch valve 16 is turned on, the negative pressure tube 131 is cut off, and the negative pressure state of the hair implantation device 40 is cut off.

[0024] Based on its technical features, the minimally invasive autologous scalp hair follicle transplantation system of the present invention may include the above-mentioned main controller 10, which may have a human-machine interface 17. The human-machine interface 17 may be configured as a touch screen or other interface, and a doctor can set the operating power of each device through the human-machine interface 17. The above-mentioned main controller 10 may be connected to three or more hair transplantation devices 40, and these control switches 50' may be implemented in multiple numbers corresponding to the number of hair transplantation devices 40. In other words, an assistant can position pre-suctioned hair follicles in multiple hair transplantation devices 40, allowing the doctor to quickly perform the hair follicle transplantation surgery. The system is also connected to the main controller 10 via a main power cable 60, which supplies power to the power supply 15.

[0025] Please refer to Figure 3. 3, when the minimally invasive autologous scalp hair follicle transplantation system according to the present invention is used for hair follicle excision surgery prior to minimally invasive hair transplantation, the surgeon holds the hair harvesting device 30 by hand and aligns the punch blade at the front end of the hair harvesting device 30 with the hair follicle unit to be excised from the scalp at the back of the head. When the motor inside the hair harvesting device 30 is driven under the control of the hair harvesting device main controller 12, the hair follicle 100 is extracted from the scalp at the back of the head, and the autologous hair follicle 100 is prepared for the subsequent hair transplantation surgery.

[0026] Please refer to Figure 4. As shown in Figure 4, before minimally invasive hair transplantation, the doctor holds the hair harvesting device 30 by hand, aligns the punch blade at the front end of the hair harvesting device 30 with the location of the hair to be transplanted on the forehead or top of the head, and controls the motor drive in the same way to cut scalp tissue 200 from the scalp. When the doctor presses the control switch 50 (pedal switch 51) with his foot, the electromagnetic pinch valve 16 opens the negative pressure tube 131, generating negative pressure in the hair harvesting device 30, which is connected to the vacuum suction pre-buffer 20, and the cut scalp tissue 200 is sucked into the flask 21 (shown in Figure 2).

[0027] Please refer to Figure 5. As shown in Figure 5, when the minimally invasive autologous scalp hair follicle transplantation system according to the present invention is used in a minimally invasive hair transplant surgery, the doctor or assistant operates the control switch 50' (pedal switch 51) corresponding to each hair transplant device 40. When the control switch 50' signal is received by the hair harvesting device main controller 12, the electromagnetic pinch valve 16 is controlled. When the electromagnetic pinch valve 16 opens the closed portion of the negative pressure tube 131, negative pressure is generated in the punch blade at the front end of the hair transplant device 40 of the vacuum suction pre-buffer 20, which is connected via the first hair transplant device tube 41, and the hair follicle 100 is sucked and positioned in the tubular front end of the hair transplant device 40. After that, the doctor or assistant operates the control switch 50' (pedal switch 51) again, causing the electromagnetic pinch valve 16 to shut off the negative pressure tube 131 and stop the negative pressure in the hair transplant device 40.

[0028] Please refer to Figure 6. As shown in Figure 6, the surgeon moves the hair transplant device 40 with the hair follicle 100 positioned at its front end to the transplant position 300 excised from the scalp tissue. Then, the surgeon operates another control switch 50' (pedal switch 51). When the signal from the control switch 50' is received by the hair harvesting device main controller 12, the compressor 14 is controlled. When gas from the compressor 14 is sent into the hair transplant device 40 through the second hair transplant device tube 42, the gas pushes the extrusion member in the punch blade of the hair transplant device 40, and the hair follicle 100 positioned at its front end is pushed to the scalp transplant position 300. This completes the hair transplant surgery for one hair follicle 100 unit. The same steps can then be repeated to complete all minimally invasive autologous hair follicle transplant surgeries.

[0029] The preferred embodiments of the present invention have been disclosed above so that those skilled in the art can understand, but they are not intended to limit the scope of the present invention. Various changes and modifications can be made within the scope of the present invention. Therefore, the scope of the claims for utility model registration of the present invention should be broadly interpreted to include such changes and modifications. [Explanation of symbols]
