Description

[Technical Field]

[0001] The present invention relates to the technical field of minimally invasive hair transplant surgery, and more particularly to a minimally invasive hair transplant device used by a hair transplant surgeon to precisely implant a single hair follicle into the scalp at the transplant site. [Background technology]

[0002] Traditional minimally invasive hair transplant procedures generally involve several key steps. First, local anesthesia is administered to the patient's scalp before surgery to prevent pain during the procedure. Next, the surgeon extracts hair follicles from the back of the patient's head or other areas with a high hair density. Traditional methods include FUE (Follicular Unit Excision), which extracts individual follicular units and then processes and examines them under a microscope to ensure they are intact and suitable for transplantation. After preparing the follicles, the surgeon plans the area where the follicles will be implanted and uses a special machine to create holes in the scalp, creating a natural-looking hairline as the implanted follicles grow. Each prepared follicle is then implanted into the pre-formed hole, and the direction and angle of each follicle are carefully adjusted to ensure the newly grown hair appears natural and matches the surrounding hairline. After the procedure is completed, the patient is given postoperative care advice and instructed to take antibiotics and anti-inflammatory medications to reduce the risk of infection.

[0003] There have been many types of hair implantation needles used to implant hair follicles. Examples of conventional, purely manual mechanical hair implantation needles include Patent Document 1. In Patent Document 1, the hair follicles were implanted entirely manually by the surgeon, so the success of the implant depended on the surgeon's sense of touch and experience. This affected the success rate of hair follicle implantation. Furthermore, Patent Document 2 uses a hair implantation device that pushes the hair follicles into the scalp using gas, but precisely positions the hair follicles using a single negative pressure suction system, which can affect the accuracy of the implant depth. Furthermore, in other designs, the disposable hair follicle implantation device of Patent Document 3 is clearly different from the two technologies mentioned above.

Then, the doctor controls the machine to generate a negative pressure suction force in the front negative pressure tube 100, and the hair follicle 300 is sucked into the needle tube 32 and positioned therein.

[0027] Please refer to Figure 7. As shown in Figure 7, the doctor inserts the front end of the needle tube 32 into the hair transplantation area 400 (pre-formed hole) on the scalp, and then controls the machine to inject gas into the rear negative pressure tube 200. The gas enters the air chamber 11 of the tube body 10 through the rear end cap 40, pushing the pneumatic member 50 and pin 60 forward to the rear end of the front end cap 20. The front end of the pin 60 can then be used to transplant the hair follicle 300 in the needle tube 32 into the hair transplantation area 400 on the scalp.

[0028] Please also refer to Figure 5. 5, the compression spring 70 in the second embodiment is designed so that when the vacuum suction force of the device is stopped, the compression spring 70 advances the pneumatic member 50 and the pin 60 to the rear end of the front end cap 20, and the front end of the pin 60 is used to implant the hair follicle 300 in the needle tube 32 into the scalp transplant site 400. This invention allows the doctor to perform the hair transplant surgery one by one in the above-mentioned order, shortening the doctor's operation time, preventing damage to the hair follicles, improving the efficiency and accuracy of the hair transplant, and enabling a hair follicle transplant surgery with a high survival rate.
