Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the 'donor site', to a bald or balding part of the body known as the 'recipient site'. The technique is primarily used to treat male pattern baldness. In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding (like the back of the head) are transplanted to the bald scalp. Hair transplantation can also be used to restore eyelashes, eyebrows, beard hair, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplants. Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin.
Hair transplantation method and apparatus
A hair transplantation method and apparatus utilizes a stereotactic robot, which includes a robotic arm, having a hair follicle introducer associated with the robotic arm.

Follicular transplantation device and method
InactiveUS20060161179A1Accurate locationAccurate removalSkin implantsDiagnosticsDilatorHair follicle
A hair transplantation device can include a generally tubular guide configured to locate a hair follicle bulb by sliding over a hair shaft down to an upper surface of a hair follicle. The guide can have a blunt distal end configured not to transect the hair follicle bulb. The hair transplantation device also includes an outer tubular member sized and configured to be advanced around the guide. The outer tubular member has a dilator and a harvester. The device can be used in a follicle transplantation method in which the guide locates a hair follicle bulb, and the outer tubular member is slid over the guide. Once the outer tubular member is aligned with the guide, the harvesting portion is advanced, cutting dermal tissue surrounding the hair follicle. The outer tubular member is then withdrawn with the hair follicle, relocated in a recipient area, and the hair follicle implanted.

Method and apparatus for transplanting a hair graft
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.

Multi-bladed surgical scalpel
InactiveUS20030097143A1Shorten the timeAmount of timeSkin implantsIncision instrumentsSurgical departmentKnife holder
This multi-bladed scalpel addresses the problem of making many small incisions in very close proximity (as close as 0.030'' / 0.75 mm) to each other, to facilitate hair transplantation. With this device, it is possible to make multiple incisions in such proximity. With the blades mounted parallel to each other, at the desired spacing, each incision does not intersect neighboring incisions, so the follicles placed in each incision will be surrounded by the maximum amount of undisturbed tissue to promote revascularization-capillary growth to provide a blood supply to each transplanted follicle. CNC machining techniques are used to create the blade holders with blade mounting sites created at the desired proximity. Medical grade epoxy is used to mount the blades, which are mounted parallel to each other. Holes are drilled so the tips of the blade group are located in a plane at an angle with respect to the blade holder for ergonomic reasons

Hair transplating device
The present invention provides hair transplant devices capable for harvesting a hair graft from a hairy area of a scalp and then implanting it into a bald area thereof in series, and it comprises a cylindrical first cutting member having a bent blade, a cylindrical second cutting member moving forward / backward along the interior of the first cutting, an extrusion member moving forward / backward along the interior of the second cutting member, and a housing providing a induction road for the second cutting member and the extrusion member. According to hair transplant devices of the present invention, it is possible to execute a hair-transplanting procedure, i.e., harvesting a hair graft from a hairy area in a scalp and then implanting the hair graft into a bald area, in series without other devices. Also, it is not necessary to incise rather big size of the scalp for harvest of hair grafts, and only very small size of a perforation is required. Therefore, no scars are left on the perforated site of the hairy area. Furthermore, since only the portion necessary for transplantation is easily harvested, the scalp is not injured. It is not required to perforate on the bald area for implantation, and thus a patient does not feel a pain.
