A hair transplant apparatus and a method for placing hair grafts into pre-made wounds capture a hair graft into a hair graft chamber readily aligned for implantation into the human scalp. The hair graft can be placed into the hair graft chamber manually or mechanically (e.g., by vacuum). A hair transplant apparatus includes a housing and a sliding rod within the housing. When the sliding rod is away from an open distal end of the housing in a first position, a hair graft can be placed into the spacing between an end of the rod and the open distal end of the housing. In a second position, the rod is advanced so the end of the rod becomes substantially flush with the distal end of the housing, thereby pushing the hair graft out of the housing and into the pre-made wound. Advantageously, the housing is aligned with the direction of the pre-made wound allowing the hair graft to slide easily into the pre-made wound without damage. Extraneous forces are eliminated by the alignment of the housing to the wound, thus creating a linear path for the hair graft to move without obstruction to finally settle in the scalp wound.

A hair transplant apparatus and method capture a hair graft into a hair graft chamber readily aligned for implantation into the human scalp. The hair graft can be placed into the hair graft chamber manually or mechanically (e.g., by vacuum). A hair transplant apparatus includes a gas-permeable stopper for utilizing gas flow to load and/or implant a hair graft. Another hair transplant apparatus includes a gas-permeable rod inside a housing. Vacuum may be utilized to load a hair graft into the hair graft chamber. The rod may be advanced toward an open distal end of the chamber so the end of the rod becomes substantially flush with the distal end, thereby pushing the hair graft out of the chamber and into the pre-made wound. Advantageously, the chamber is aligned with the direction of the pre-made wound allowing the hair graft to slide easily into the pre-made wound without damage. Extraneous forces are eliminated by the alignment of the chamber to the wound, thus creating a linear path for the hair graft to move without obstruction to finally settle in the scalp wound.

A hair implantation instrument herein employs a simple means for capturing a hair graft in a needle in a position for implantation into a scalp and an escapement mechanism for withdrawing the needle in a manner to leave the graft in the scalp. The needle is moved with respect to a rod which positions an implanted graft properly when the needle is withdrawn. The apparatus also defines a sheath over the needle for properly positioning a graft during a graft capture operation. The escapement mechanism is vacuum controlled in one embodiment and spring controlled in a second embodiment.

The invention relates to an artificial wig with no hair knot on the scalp surface layer and the manufacturing method of the wig, and belongs to the technology field of the hair product. The artificial wig with no hair knot on the scalp surface layer in the invention is composed of a fine mesh, a silky object and hair as the artificial scalp in a connecting way, the two layers of the fine mesh layer and the silky object layer are stunk together, and the hair transplanted and knotted on the inner side of the fine mesh is penetrated through the two layers of the fine mesh layer and the silky object layer, and is extended to the outer side of the silky object.

The present invention is directed to methods for readily propagating somatic hair follicle stem cells or melanocyte stem cells. The methods comprise enhancing guanine nucleotide (GNP) biosynthesis, thereby expanding guanine nucleotide pools. This in turn conditionally suppresses asymmetric cell kinetics in the explanted cells. The methods of the invention include pharmacological methods and genetic methods. For example, the resulting cultured somatic hair follicle stem cells can be used for a variety of applications including cell replacement therapies such as hair transplants, gene therapies, and tissue engineering applications, such as the generation of artificial skin and skin regeneration strategies including skin grafts.

A direct hair transplanting device enabling sequential harvesting of single hair follicles from a donor region and implantation of the same at a recipient zone of the scalp comprising a tubular housing (30) with a forwardly projecting tubular needle (2) with an outermost end being formed with a conical obliquely cut knife edge cutting surface. A hair follicle is extracted through rotation of the cutting surface of the needle around a selected hair follicle at the target donor region of the scalp and implantation of the same at a selected recipient locus of the scalp being effected through initiating a forward stroke of a push rod (7) slidable within the interior of tubular needle (2) to implant the hair follicle into the scalp. Appropriate regulation and fine adjustment of the depth of intrusion of needle (2) into the scalp is obtained through differentiated depth of screwing of an internally threaded tubular shaft (35) holding the needle around an externally threaded perimeter of a cylindrical member (34) detachably mounted onto the tubular housing (30).

The base sheet (11) made of elastic material is stretched, and the middle part of the hair section is caught by the reciprocating motion of the needle (41a), forming a shape-retaining curved part (30a) in the middle part. The curved portion is left on one side of the base sheet and bonded on the one side by the first adhesive layer (111), and a pair of long hair extensions (30b) extending from both ends of the curved portion pass through when the needle is raised. A hole (11a) formed by breaking through the substrate is pulled out on the other side of the substrate. After the predetermined number of hair segments are planted on the base sheet and bonded as above, the stretched state of the base sheet is released or relaxed, and the elasticity of the base sheet is used to make it shrink and the diameter of the above-mentioned hole is reduced to form the above-mentioned hair that fully covers the base sheet. The second adhesive layer (112) on one side serves as the mounting surface against human skin.

The invention discloses a method and system for intelligent fixed-point planning of a hair transplanting area. The method comprises the steps: determining a first hair line area according to the first body feature information of a first user; according to a matching result of the first hairline area and the hair transplantation hairstyle database, acquiring a first matched hairstyle; acquiring a first hair loss grade; calculating the number of scalp hair follicles according to the scalp feature information of the first hair transplantation area to obtain the number of first hair follicles; acquiring a first hair quality damage degree; inputting the first hair loss grade, the first hair follicle number and the first hair quality damage degree into a hair transplantation survival rate evaluation model to obtain a first hair transplantation survival rate evaluation result; and if the first hair transplanting survival rate evaluation result reaches a preset survival rate standard, performing hair transplanting operation on the first user. The invention solves the technical problems that: in the prior art, omission is prone to occurring due to long manual hair transplanting time, hair follicle damage occurs in the hair transplanting process of a patient, and the hair transplanting effect is affected.

A base sheet (11 ) of elastic material is stretched, and the intermediate portion of a hair segment is caught by reciprocating needles (41a) to form a shape-retainable turn (30a) at said intermediate portion. The turn remains on one side of the base sheet and secured to said one side with a first adhesive layer (111), whereas a pair of lengthwise hair extensions (30b) extending from the opposite ends of the turn pass through holes (11a), formed by penetration of the needles during elevation thereof, to beyond the other side of the base sheet. After a predetermined number of the hair segments are transplanted and secured to the base sheet, the stretched condition of the base sheet is released or loosened, so that it contracts due to elasticity to thereby reduce the diameter of the holes. Then, a second adhesive layer (112) is formed entirely on the said one side of the base sheet for fitting on human skin.
