The clamp is named after David Geoffrey Pennington, an Australian surgeon who is a pioneer of microsurgeries.
It is commonly used in body piercing to hold the skin in place, and guide the needle through it.
In addition to the shape of the gripping head, a distinction is also made between forceps with open and closed jaws.
Open forceps can be removed directly after the stitch without having to shorten the intravenous cannula or piercing needle with scissors beforehand, but offer a slightly less secure hold than closed forceps.
