Abstract
Abstract Lacerations of the scalp are closed by pulling the hair on opposite sides of the laceration perpendicular to the skin and then together directly above the laceration, thus pulling the skin together so that the edges are in close proximity. A clamp is applied to the hair, holding the skin in place with the edges close enough to heal together. Thus, use of sutures and necessity of shaving hair adjacent the wound is avoided. The clamp has two pivoted jaws lined with a friction material which resists slippage and securely grips the hair when the jaws are closed and latch means for holding the jaws closed. The clamp is preferably of materials which may be sterilized.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A method of closing lacerations of the scalp and other areas where hair surrounds the laceration comprising pulling the hair from areas outside the opposite side edges of the laceration approximately perpendicular to the skin, then crossing the hair from opposite sides of the laceration approximately directly above the laceration, and thereby pulling the edges of the laceration together, providing a clamp having a pair of jaws hinged together at one end, having friction material in the inner faces of the jaws intermediate the ends, and jaw latching means at the ends opposite the hinge, applying said clamp to the hair disposed parallel to the skin at a distance substantially above the skin to restrain movement of the hair and hold said edges together, and maintaining said clamp in place until said edges have healed sufficiently to remain together without said clamp, and then removing said clamp.
Claim 2
Independent Claim
147 words
A method of closing lacerations of the scalp and other areas where hair surrounds the laceration comprising pulling the hair from areas outside the opposite side edges of the laceration approximately perpendicular to the skin, then crossing the hair from opposite sides of the laceration approximately directly above the laceration, and thereby pulling the edges of the laceration together, providing a clamp having a pair of jaws hinged together at one end, having friction material in the inner faces of the jaws intermediate the ends, and jaw latching means at the ends opposite the hinge, applying said clamp to the hair disposed parallel to the skin at a distance substantially above the skin to restrain movement of the hair and hold said edges together, and maintaining said clamp in place until said edges have healed sufficiently to remain together without said clamp, and then removing said clamp.
Claim 3
Dependent Claim
27 words
The method of claim 1 in which said applying said clamp secures the hair so that longitudinal movement of the hair transverse to the scalp is restrained.
Claim 4
Dependent Claim
175 words
A clamp for use in closing lacerations of the skin in the scalp having hair surrounding the laceration, comprising a first jaw, a second jaw, said jaws being rectangular in plan and relatively long, thin and narrow, hinge means at one end of said jaws, first latch means on said first jaw, and second latch means on said second jaw cooperable with said first latch means to hold said jaws closed, first and second layers of friction material, one such layer on the inner surface of each of said jaws to restrain slippage of said hair clamped between said jaws, longitudinally extending projection on the inner surface of said first jaw, a cooperating longitudinal depression in the inner surface of said second jaw directly opposite such projection when said clamp is closed with said projection extending partially into said depression, said hair being sharply bent by said projection and said depression when clamped between said jaws, said layer of friction material on said first jaw being formed with a slit for protrusion of said projection.
Claim 5
Dependent Claim
175 words
A clamp for use in closing lacerations of the skin in the scalp having hair surrounding the laceration, comprising a first jaw, a second jaw, said jaws being rectangular in plan and relatively long, thin and narrow, hinge means at one end of said jaws, first latch means on said first jaw, and second latch means on said second jaw cooperable with said first latch means to hold said jaws closed, first and second layers of friction material, one such layer on the inner surface of each of said jaws to restrain slippage of said hair clamped between said jaws, longitudinally extending projection on the inner surface of said first jaw, a cooperating longitudinal depression in the inner surface of said second jaw directly opposite such projection when said clamp is closed with said projection extending partially into said depression, said hair being sharply bent by said projection and said depression when clamped between said jaws, said layer of friction material on said first jaw being formed with a slit for protrusion of said projection.
Claim 6
Dependent Claim
20 words
A clamp according to claim 3 in which said layers of friction material extend circumferentially around each of said jaws.
