Benefits of technology

"The present invention is about a device for implanting hair grafts into the scalp. The device includes a needle with a fixed rod inside it, which prevents the graft from moving during the extraction process. The needle is quickly withdrawn to extract the graft while keeping it in place. The device also includes a vacuum to capture the graft and a spring-biased piston to move the graft into the needle. The device can be used with a vacuum-operated graft capture device. The technical effect of this invention is to improve the success rate of hair graft implantation by facilitating the insertion and extraction of the graft while keeping it in place."

Problems solved by technology

But quick extraction of the needle also increases the risk of dislodging the graft.

Embodiment Construction

[0024]FIG. 1 is a schematic representation of a system 10 for hair transplantation in accordance with the principles of this invention. The system includes an instrument 11 operative to capture a hair graft in a properly oriented and properly placed position for implantation into the human scalp.

[0025] Instrument 11, in one embodiment, is seven inches long and three-fourths of an inch in diameter and is normally held between the forefinger and the thumb. The index finger is left free to operate the instrument as will be more fully explained hereinafter.

[0026] The instrument is operative to capture a hair graft illustratively from a supply of grafts previously extracted from an excised portion of the scalp of the patent receiving the implantations.

[0027]FIG. 2 represents individual hair grafts at 12. The instrument 11 of FIG. 1 is operated to capture a hair graft as an initial step in the implantation procedure.

[0028] The operation of instrument 11 is described in connection with...

Abstract

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 The needle is moved with respect to a rod which positions an implanted graft properly when the needle is withdrawn.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.

Description

FIELD OF THE INVENTION [0001] This invention relates to apparatus for transplanting hair grafts, and, more particularly to apparatus for implanting hair grafts primarily into a human scalp. BACKGROUND OF THE INVENTION [0002] The transplantation of hair grafts into a human scalp is well understood. The present state of the art calls for excising a hair-rich area of the scalp, dissecting the excised scalp segment to obtain individual grafts for implantation, creating an implantation site in a bald area of the scalp and implanting an individual graft into the prepared implantation site. It is also known that a preferred graft for implantation comprises a follicular unit which is the basic microscopic anatomy which contains 1-4 hairs bunched together. [0003] Implantation instruments for use by a surgeon to implant hair grafts are well known. For example, U.S. Pat. No. 6,059,807, issued May 9, 2000 discloses a hair graft implantation instrument which includes a hollow needle which is mov...
