The stud piercing housing is provided with a push rod guiding cylinder embedded in the first mounting cavity, and a piercing assembly is at least partially located in the push rod guiding cylinder and is clamped and positioned by both the stud piercing housing and a bottom wall of the first mounting cavity.

A gun-shaped ear piercer, comprising a front portion (1) and a rear portion (2) which are sleeved and can move relatively. A track (7), having a front slot (7a) for mounting a stud base mounting portion (9) disposed on one end thereof away from the rear portion (2), as well as a fixed portion (11) for mounting a stud mounting portion (10) disposed thereon in a sliding manner, is disposed on the front portion (1). A firing device corresponding to the fixed portion (11) is disposed on the rear portion (2). The front portion (1) comprises a grip having an unlocking trigger (6) disposed on a front side thereof, an elastic reset device as well as an aiming stroke restrainer are disposed between the front portion (1) and the rear portion (2), the aiming stroke restrainer is used to restrain the firing device from moving to an aimed position.

An ear-piercing device of a gun shape that can pierce an ear lobe quickly with less pain. The ear-piercing device includes a frame, a handle, and a plunger unit coupled to the frame. The plunger unit includes a plunger and a compression spring. A cartridge can interchangeably be coupled to the frame, wherein the cartridge includes a piercing member that can be driven by the plunger and protrudes from the housing into a compression module. The housing and compression module can clamp the ear lobe, and the piercing member can make a hole in the ear lobe. The compression module can include a cutter to snip off the portion of the piercing member inserted into the compression module. The piercing member includes a sleeve part and a needle part. The needle part makes the hole and the needle part and portion of the sleeve get snip off, while a portion of the sleeve is retained in the ear lobe.

Disclosed are devices, system and methods for using wearable sensors, such as an earring configured for insertion in an artificially-created cavity in a wearer's ear, the earring including one or more sensing devices in communication with a processing device via a wireless link.

An earring post construction that includes an elongated earring post and a cup that is for the support of a decorative piece. The elongated earring post and cup are integrally formed in a single piece construction so as to eliminate the use of any attachment means between the elongated earring post and the cup; in combination with a securing stud that engages with the elongated earring post, and wherein there is provided an elongated passage in the elongated earring post so as to minimize the amount of precious metal used in constructing at least the elongated earring post.

The gauge enhancer body jewelry system allows individuals to increase their earlobes to the size they desire. It eliminates the need to constantly purchase new gauges as earlobes expand. It reduces pain associated with the enlargement process and forcing uncomfortably large gauges into earlobe holes. As designed it decreases the risk of infection from removing and replacing gauges. The present invention saves a considerable amount of time and frustration, and allows individuals to enlarge their earlobes at their own pace.

An earring back for secure but easily releasable engagement with an earring post or extension is provided. In an embodiment, the earring back includes an outer casing and an internal, compressible material such as silicone. The earring back further defines a center opening for receiving and engaging with an earring post or extension. In an embodiment, the outer casing comprises two pieces. A first piece is a back piece with an enclosed back end, an open opposite end providing access to an inner cavity, and a lip extending laterally from the open end. The second piece is a front piece having a radius larger than the radius of the lip of the back piece and defining the center opening. In an embodiment, a circumferential portion of the casing front piece is folded over and around a lip of the compressible material and the casing back piece lip and compressed.

A bioabsorbable tissue support is inserted into a tissue of a subject during, or after, puncture of the tissue. The bioabsorbable tissue support includes a material that is gradually absorbed into the punctured tissue in time, and disappears. The bioabsorbable tissue support may be inserted standing alone, or in association with a permanent or temporary non-bioabsorbable tissue support, may define the shape of the punctured hole, and/or may release useful or ornamental chemicals into the punctured tissue. The chemical may include an antibacterial material, an antifungal material, an antimicrobial material, topical anesthetic, a temporary or permanent dye material, and/or an antiproliferative agent. The non-bioabsorbable tissue support may include a self-expanding material that enlarges the size of the puncture in time. The bioabsorbable tissue support may have the form of a tube and/or a mesh of variable peripheral shapes, be elongated, and/or have attachable and detachable end plates and pointed tips.
