Description

BACKGROUND

People have enjoyed the aesthetic pleasures of adorning their bodies for millennia. One ancient form of body adornment is body piercing, in which a hole is made in a portion of the human body, and an ornamental object is anchored therein. A recent advancement in the body piercing arts is the development of the technique of inserting a surface anchor under the skin, to form a semi-permanent anchor on which body jewelry may be attached. The surface anchor offers the aesthetic advantage of causing the body jewelry to appear to be directly screwed to the wearer's body, which is visually striking. Some prior surface anchors included a base plate that is formed of a flat solid piece of metal, but these were relatively heavy and prone to slide undesirably under the skin. Other prior surface anchors included a base plate with internal holes formed therein. The holes in the base plate allowed tissue to grow therethrough in situ, thereby securing the anchor against sliding. However, these surface anchors with internal holes present a drawback to those people who eventually decide to remove the anchor, since tissue growth through the holes can result in a painful and injurious removal.

DETAILED DESCRIPTION

As illustrated in FIGS. 1-9, a surface anchor 10 for body jewelry is provided. The surface anchor typically includes a base formed of an elongated plate. The plate provides stability when inserted under the skin of a subject. The plate includes a proximate end 12c and a distal end. The proximate end 12c is gradually radiused. In the illustrated embodiment, a 0.054 inch radius R is used. Alternatively, a radius R of between 0.04 and 0.07 inches may be used, preferably between 0.05 and 0.06 inches. A radius R in this range provides a smooth curved surface that may easily be inserted into and removed from a slot in the skin of a user, as described below.

A proximate end 12c of the base is coupled to a post 16, to which body jewelry may be attached. The post 16 is set back a distance D1 0.06 inches from the furthest tip of the radiused proximate end 12c, although a setback distance D1 in the range of 0.03-0.08 could also be used. Setback distances in these ranges provide sufficient horizontal surface around the post 16 for the tissue to securely contact, which may inhibit the back end of the surface anchor 10 from becoming dislodged after being placed in situ. The height of the post, indicated at A in the Figures, may be of varying height depending on the preference of the user. For example, a height A of 1/16 inch, 2 mm, 3/32 inch, ⅛ inch, 5/32 inch, or 3/16 inch may be used. The post is designed to stick out through the skin when the plate is installed in situ under the skin, as best seen in FIG. 9. Returning to FIGS. 1-8, the post 16 includes a fastening structure 16a for securing the body jewelry to the post. The fastening structure 16a is illustrated as internal threads that engage with corresponding threads formed in the body jewelry, although it will be appreciated that other fastening structures may also be employed. The outer diameter D2 of the post is typically 0.064 inches, with posts being available having an outer diameter from 0.16 to 0.048 inches. It will be appreciated that this range of post sizes corresponds to 8 ga to 18 ga, in gauge units.

A distal end of the base includes a slot 14 extending from an edge of the base inward into an internal region of the base. The slot is bounded on opposite sides by a pair of elongated structures 12a and 12b, which serve to enable the anchor to slide into place within the skin, also provide a broad footprint for support. The slot is open to the distal end of the base, and is shaped to be longer than it is wide. The slot typically has a width W1 of 0.03 inches, and a length L1 of 0.12 inches, with a width W1 between 0.01 and 0.05 inches, and a length L1 between 0.05 and 0.2 inches being possible. It will be appreciated that the width to length ratio for the slot is typically less than 1:1, and is approximately 0.25 in the illustrated embodiment. Width to length ratios of between 1:5 and 1:1 are possible, with 1:4 being preferred in some cases. The slot width W1 is between ¼ and ½ of the width W2 of the elongated plate, and in the preferred embodiment is 0.28 times the width of the elongated plate. Slot and elongated structure dimensions in these ranges described above enable the elongate structures to be sufficiently strong to provide horizontal stability when in situ, while also enabling sufficient tissue to grow into the slot to prevent rotational or other movement of the surface anchor in situ.

An inside perimeter of the slot 14 is typically formed by two parallel sides connected together by a radiused edge on a central, innermost edge of the slot. Alternatively, the sides of the slot may open at an angle so as to get wider toward the opening or mouth of the slot. The sides of the slot may also be curved instead of straight in some embodiments. The mouth or opening of the slot 14 typically opens to the distal end of the elongated plate 12, in between the distal ends of each of elongated structures 12a, 12b. Each of the distal ends of elongated structures 12a, 12b is typically radiused. These radiuses, like all other radiuses described herein, may alternatively be squared ends, or polygonal in shape, depending on the preferences of the user. The slot 14 is typically centered widthwise within the elongated plate, although in alternative embodiments it need not be so centered.

The elongated plate typically has a length L2 of 0.28 inches, although the length L2 may range between 0.2 and 0.3 inches, or in some embodiments, 0.15 and 0.35 inches. Other lengths L2 may also be provided. The elongated plate is typically about 0.11 inches in width W2, with a width W2 of between 0.05-0.2 inches being possible, and preferably has a width W2 of between 0.08 and 0.12 inches. The length to width ratio for the elongated plate 12 is typically between than 2:1 and 3:1, and in a preferred embodiment is about 2.6:1. The thickness T of the elongated plate is 0.02 inches, although any suitable thickness T may be used, such as between 0.01 and 0.03 inches. Elongated plate dimensions in these ranges enable the elongate plate to serve as a strong, secure base for the post and jewelry in situ, and help ensure the post extends orthogonal to the skin surface of the user, without undesirably tilting or leaning at an angle.

As shown in FIG. 9, during use the surface anchor 10 may be inserted in situ under the skin of a user, with the post extending through an opening in the skin. Body jewelry 20 may be secured to the post of the surface anchor, to thereby form a slotted body jewelry assembly 5. The body jewelry 20 typically includes a jeweled or other ornamental surface 22, mounted in a setting 24. The body jewelry 20 also typically includes a threaded shaft 26 that engages with the internally threaded post 16 of the surface anchor. In situ, the surface anchor sits with the elongated plate 12 resting under the skin, and the post 16 extending through a semi-permanent opening in the skin. As the user wears the surface anchor for a period of time, tissue may grow into the slot 14, securing the surface anchor against rotation under the skin. This may be an advantage for users who wish to secure to the anchor body jewelry 20 that has a particular orientation, for example, since the anchor is less likely to rotate undesirably when the tissue has grown within the slot.

Should a user desire to have the surface device removed, an incision may be made in the skin as indicated in FIG. 9, and the surface anchor may be pulled out of the incision in a direction generally parallel to slot 14 and in the opposite direction as the opening of slot 14, as indicated by the large arrow in FIG. 9. In this way tissue that has grown within the slot 14 may easily slide out the opening in the end of slot 14, to enable the surface anchor to be easily removed. This has the benefit of avoiding the damage discussed in the Background associated with the removal of surface anchors with internally formed holes. The tissue in such holes of prior devices would be prone to rip or tear when the surface anchor was removed. With anchors according to the subject invention, the injury and pain associated with such tearing is avoided. Typically, the surface anchor is manufactured of a metal such as implant grade titanium, so avoid adverse reaction with the tissue.

It should be understood that the embodiments herein are illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description preceding them, and all changes that fall within metes and bounds of the claims, or equivalence of such metes and bounds thereof are therefore intended to be embraced by the claims.
