Description

Hair follicle transplanting device Technical Field The utility model belongs to the technical field of medical beauty equipment, and particularly relates to a hair follicle transplanting device. Background Hair follicle transplantation is a common method of treating hair loss and other hair loss symptoms, the primary process of which involves extracting healthy follicular units from the back occiput of the patient's head, and then precisely planting these follicular units into the area where increased hair density is desired. Autologous hair transplantation surgery is classified from hair follicle extraction modes, mainly including scalp and hair follicle harvesting methods (follicle unit transplant, FUT) and hair follicle harvesting methods (Follicle Unit Extration, FUE), and is currently a very mainstream hair follicle harvesting technology because of its obvious advantages. FuE subdivides the hair follicles in the collected areas by taking down the hair follicles and then making single hair follicles, uses tools to collect the hair follicles, uses different diameters and sizes for different hair follicle conditions, accurately collects hair, completely takes out target hair follicles, then implants the target hair follicles into the areas to be implanted through the tools, and the collected and implanted hair follicle areas comprise head, eyebrow, eyelash, beard, chest, eyelash, pudendum and the like. Most of the prior hair follicle transplanting devices still have the following defects of 1, difficult assembly and disassembly, 2, incapability of directly judging the direction of hair transplantation, incapability of determining the direction of a needle tube by repeated assembly and disassembly, 3, uncomfortable holding, time and labor waste for a doctor to adjust the direction of equipment in actual operation, reduced operation efficiency, 4, incapability of intuitively confirming the specifications of the hair follicle transplanting device and the needle tube through products, 5, poor user experience due to lack of an effective buffering mechanism, unnecessary pain and uncomfortable feeling possibly brought to a patient in the puncturing process, easy fatigue of the doctor operation, and 6, easy pollution or accidental injury of a needle head when not in use, thereby being unfavorable for keeping a sterile environment and increasing medical risks. For example, the Chinese patent publication No. CN 218943462U discloses a hair follicle transplanting device capable of displaying color codes, which can solve the defects of difficult hair follicle loading, inapplicability, inconvenient operation and the like, but has the defects that the needle length cannot be adjusted due to the fact that a solid needle is not matched with a hollow needle, and pain and uncomfortable feeling are brought to a patient in the puncturing process due to the fact that an effective buffering mechanism is not available. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a hair follicle transplanting device. In order to achieve the above purpose, the present utility model is realized by adopting the following technical scheme: The utility model provides a hair follicle transplanting device, includes interior axle, the button of being connected with interior axle one end, installs the outside outer axle of interior axle and the outside needle knob that adjusts of cover in interior axle, interior inner core assembly, spring and the needle subassembly of installing in proper order, interior inner core assembly includes solid needle file and solid needle, the one end and the solid needle file fixed connection of solid needle, and the other end of solid needle passes spring and needle subassembly in proper order. Preferably, the needle assembly comprises a hollow needle seat and a hollow needle, one end of the hollow needle is fixedly connected with the hollow needle seat, the other end of the hollow needle penetrates out of the inner shaft, the other end of the solid needle sequentially penetrates through the spring, the hollow needle seat and the hollow needle, and the tail end of the solid needle is arranged inside the hollow needle.
