<p>This invention is a device (1) for implanting a small-diameter capillary graft into the scalp, comprising a hollow needle (13) pierced by a throughbore having a smaller diameter than the graft, and suitable for gripping, by its end, one end of the said graft through the needle. The needle is mounted so as to slide in a cylindrical sheath (12) between a first position, in which is retracted inside the sheath, and a second position for gripping and for inserting the graft into the scalp, in which the needle projects beyond the end of the sheath. The needle is actuated between the first, the second positions, preferably by application and release of a vacuum to an enclosure (18) which is defined by a cylindrical tube which is closed on a first side by the sheath, and on a second side by a plug fastened to a distal end of the needle. A communication port is formed in the needle communicating with the enclosure so as to allow vacuum in the enclosure to facilitate gripping of the capillary graft by vacuum. An orifice (8) is provided in a wall of the cylindrical tube so as to allow a surgeon rapidly to apply, and release vacuum in the enclosure.</p> |
