Abstract: Device and method for implantation of hair grafts into the scalp of a patient. In the device, a cross-sectional shape of a rod riding in an implantation needle is configured with respect to the needle to communicate a vacuum in a chamber anterior to the needle forward to an interior of the needle, thereby facilitating loading of the hair graft into the device by direct-to-needle aspiration of the hair graft.

Abstract: The invention relates to a device (14, 14?) for loading hair grafts into a Choi implanter-type implantation instrument, including an element comprising a first hole (18a) connected to a channel (17) that opens into a fluid-discharge chamber (21); a second hole (22) which can be connected to the fluid-discharge chamber (21) and define a path with the channel (17) such as to allow a needle (5) of an implantation instrument (1) to be introduced into the path through the second hole (22); and a connection means (23) for connecting the fluid-discharge chamber (21) to a vacuum source (27). The first hole (18a) is connected to a first tubing (20) used to deliver a graft (12) such that the graft (12) can be inserted into the needle (5) of the implantation instrument (1).

Abstract: Method and apparatus for automated staging of hair grafts using a camera for capturing one or more images of a staging area constructed for holding the hair grafts, and a controllable robotic arm having an aspiration tip mounted at a tool end thereof. An image captured by the camera is processed to identify a position of a hair graft in the image, and subsequent to distinguishing between a base end and a hair end of the hair graft in the image, an aspiration point is defined based at least in part on position of either or both of the base end and the hair end. The robotic arm is controlled to move the aspiration tip to the aspiration point, for aspiration of the hair graft into the aspiration tip.

Abstract: A device and system for implanting a hair graft, the device having an elongated body; an intermediate reservoir operably coupled to an anterior end of the elongated body and extending axially therefrom; a skin abutment piece movably coupled to an anterior end of the intermediate reservoir; and a beveled hollow needle operably coupled to an anterior end of the skin abutment piece. The system also includes a source of pressure operably coupled to the device; a hair graft container operably coupled to the device; a vacuum source operably coupled to the device; a differential pressure detector operably coupled to the device; and a controller in communication with the source of pressure, the hair graft container, the vacuum source, and the differential pressure detector.

Abstract: The invention relates to a device for surgical cutting of strips of scalp into multiple calibrated hair grafts, of identical small size. The device has a blade holder designed to allow vertical positioning of multiple parallel and equidistant blades, so that the cutting edges of said blades are aligned in one and the same horizontal plane, these blades then projecting from a support surface, and a plate of flexible material is intended to be placed flush with the cutting edges of the blades and is associated with an applicator associated with retention or abutment and, if appropriate, guide means making it possible to apply or press this plate onto the cutting edges of the blades, parallel to said support surface, while ensuring that this plate does not move beyond a limit position set at a distance from the support surface which is greater than the thickness of the strips for which the surgical cutting device is intended.
