ABSTRACT:
Embodiments of a fingernail or toenail drilling instrument are described for relieving the pressure of an injured appendage beneath the finger- or toenail. The drilling instrument has a shaft with a sharp, pointed tip and preferably has a generally concave surface, that may be part of an interior hollow surface near the tip point or that may be a concave outer surface near the tip point, making the shaft an effective piercing and drilling instrument. The invented drill may include a holder covered by a removable case, and the case may be adapted to snap onto the holder as an extension for use as a handle. Preferably, the case exterior surface has texture or protrusions for creating a gripping surface for improving accuracy and preventing the drill from slipping the user's fingers. This drilling instrument can be available without a prescription because it conceivably is not usable or adaptable to be a fluid-injection shaft. The drilling instrument is hand-powered by the user's fingers rotating it around its longitudinal axis and gently pressing it into the nail; therefore, no motor or other power source is needed. The invented drilling instrument allows an injured party or the person giving first aid to save the expense of a doctor visit and to save time and expense over obtaining a prescription. Also, with this invention, the doctor will be spared the time involved with dealing with a minor problem that could be easily handled by the injured individual without his assistance.
