Even though designed to only pierce earlobes, ear piercing instruments are commonly used to pierce ear cartilage, and sometimes to pierce non-ear body parts.

Ear piercing instrument designs

The traditional design is built around a spring that stores potential energy when the ear piercing instrument is pulled into the cocked position. Pre-sterilized starter earrings of the stud earring design, are typically provided in pairs by the manufacturer in sealed plastic containers. One starter earring is loaded into a receiving tube in the cocked portion of the instrument, and its matching friction back is loaded into a holder closer to the main part of the instrument. The earlobe is inserted between these two parts of the instrument, and the trigger is squeezed, releasing the spring, and causing the instrument to close with considerable pressure, forcing the sharpened stud earring through the earlobe, engaging it into a friction back. Most disposable models, intended for home use, are variations of the traditional design

An improvement on the standard piercing instrument is the Disposable Cartridge (or Cassette). These are very similar to the traditional design (above), other than the stud holder and clasp holder are entirely disposable. In some parts of the world, e.g. most of Europe and Australia, this modification is either specifically required (eg in Scotland) or implied by Health And Safety legislation. The image shows a White Disposable Cartridge System, loaded with a with a blue cartridge and a gold stud.

The newer design uses a similar concept, however, instead of using potential energy stored in a spring to force the starter earring through the earlobe, energy is provided directly by the operator through a hand grip. This provides an additional level of control. Also, these models usually provide the starter earrings in special capsules that allow the pre-sterilized earrings to be loaded into the instrument without the operator touching them. A wider variety of jewelry shapes and designs are available for newer piercing instruments.

Ear piercing instruments are designed to pierce using 20- or 18-gauge earrings, normally made out of surgical steel, 24 kt. gold plated steel, 14 kt. gold, or titanium.

Controversy regarding the use of piercing instruments

Reusable piercing instruments are difficult or impossibile to sterilize. Also, they are almost always used by persons who have little or no formal training in related health areas such as cross contamination, and may only have minimal training in using the instrument itself. Many of these instruments cannot be autoclaved because some of the components from which they are constructed would be destroyed by the process, and even if autoclavable, almost all businesses where they are used lack autoclaving facilities.
