Abstract
Abstract A straight needle for penetrating the scalp substantially parallel to the underlying bone structure has a trailing tissue-compatible flexible preferably transparent plastic tube which contains a stainless steel bushing. After being pulled through the scalp puncture openings by the needle, the needle with a portion of the trailing tube is severed and discarded with a section of the tube and the contained bushing remaining in the scalp with end portions projecting outwardly of the puncture openings. The external end portions of the bushing are turned upwardly approximately normal to the scalp and a parallel lock bar to which a hair piece may be anchored is attached in close parallel relationship to the implanted bushing by a wire which is threaded through the bushing and its encasing tube before bending the ends of the bushing. The wire ends are also threaded through the tubular lock bar and tightened prior to crimping the ends of the lock bar on the wire and removal of excess wire ends to complete the implanted unit. Sterile packaging is featured. Only simple tools are required. Strain on the edges of scalp puncture openings is eliminated. By a modification, plural bushings can be implanted in the scalp in a connected array by continuous crimped wires which will prevent both the wires and the bushings from moving relatively. The wire crimped portions between bushings lie close to the scalp for the attachment of a hair piece.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
284 words
A scalp implant for attaching a hair piece to the scalp comprising a needle adapted to puncture the scalp generally parallel to the surface of the skull and thereby form entrance and exit puncture openings in the scalp, a trailing tube of tissue-compatible material attached to the needle and adapted to be severed therefrom after the needle has drawn said tube into implanted relationship with the scalp with opposite ends of the tube extending substantially equidistantly outside of the scalp beyond said entrance and exit puncture openings, a metallic sleeve bushing contained bodily within said tube and having a central main portion substantially equal in length to the distance between said entrance and exit puncture openings and comparatively short end portions adapted to be bent upwardly approximately at right angles to said central main portion to thereby project outwardly of and above the scalp, said comparatively short end portions of the bushing being substantially equal in length to corresponding end portions of said tube within which said metallic sleeve bushing is contained, and said tube end protions being bendable with said short end portions of the metallic bushing, a substantially straight tubular lock formed separately from and substantially equal in length to said central main portion of said metallic bushing, and a lock bar attaching wire threadable through said bushing and said lock bar and adapted when tightened and secured to position said lock bar between the tops of the comparatively short upwardly bent bushing and tube end portions with the lock bar outside of the scalp and substantially parallel to said central main portion of the bushing and spaced therefrom, whereby said implant is in the form of a closed substantially rectangular loop.
Claim 2
Dependent Claim
284 words
A scalp implant for attaching a hair piece to the scalp comprising a needle adapted to puncture the scalp generally parallel to the surface of the skull and thereby form entrance and exit puncture openings in the scalp, a trailing tube of tissue-compatible material attached to the needle and adapted to be severed therefrom after the needle has drawn said tube into implanted relationship with the scalp with opposite ends of the tube extending substantially equidistantly outside of the scalp beyond said entrance and exit puncture openings, a metallic sleeve bushing contained bodily within said tube and having a central main portion substantially equal in length to the distance between said entrance and exit puncture openings and comparatively short end portions adapted to be bent upwardly approximately at right angles to said central main portion to thereby project outwardly of and above the scalp, said comparatively short end portions of the bushing being substantially equal in length to corresponding end portions of said tube within which said metallic sleeve bushing is contained, and said tube end protions being bendable with said short end portions of the metallic bushing, a substantially straight tubular lock formed separately from and substantially equal in length to said central main portion of said metallic bushing, and a lock bar attaching wire threadable through said bushing and said lock bar and adapted when tightened and secured to position said lock bar between the tops of the comparatively short upwardly bent bushing and tube end portions with the lock bar outside of the scalp and substantially parallel to said central main portion of the bushing and spaced therefrom, whereby said implant is in the form of a closed substantially rectangular loop.
Claim 3
Dependent Claim
44 words
A scalp implant for attaching hair pieces to the head as defined by claim 1, and said metallic bushing being notched at the opposite ends of said central main portion to facilitate the upward bending of said comparatively short end portions of the bushing.
Claim 4
Dependent Claim
39 words
A scalp implant for attaching hair pieces to the head as defined by claim 2, and said metallic bushing having a single pair of notches on one side thereof and both notches being aligned circumferentially of said metallic bushing.
Claim 5
Dependent Claim
38 words
A scalp implant for attaching hair pieces to the head as defined by claim 1, and said needle comprising a substantially straight needle arranged substantially coaxially with said trailing tube prior to the installation of said scalp implant.
Claim 6
Dependent Claim
101 words
A scalp implant for attaching hair pieces to the head as defined by claim 1, and tubular lock bar comprising a metallic element, and said lock bar attaching wire comprising an elongated single section flexible wire threaded through said bushing and having its opposite ends extending beyond opposite ends of the bushing and threaded through said lock bar in opposite directions with the opposite wire ends projecting beyond opposite ends of the lock bar, whereby pulling on such wire ends will draw the lock bar into its use position between the tops of the upwardly bent bushing and tube end portions.
Claim 7
Dependent Claim
42 words
A scalp implant for attaching hair pieces to the head as defined by claim 1, and said tubular lock bar fixed in its assembled relationship to said attaching wire by being clinched to the wire near opposite ends of said lock bar.
Claim 8
Dependent Claim
43 words
A scalp implant for attaching hair pieces to the head as defined by claim 5, and said lock bar being clinched on two strands of said attaching wire extending therethrough to fix the lock bar in its use position on said scalp implant.
