A tool, such as a medical instrument that can provide a variety of different functions. Specifically, the present invention includes a variety of heads that each can allow the medical instrument to perform a different function. Each of the heads are operatively coupled to a holding apparatus of the medical instrument such as by the use of a sliding mechanism. In a preferred embodiment, the medical instrument is a forceps with heads operatively coupled to each arm. This coupling is done in such a way that a head can fully retract into a position such that no portion of the second medical head extends beyond the holding apparatus when not in use. This means that at most one of the heads extends from the holding apparatus of the medical instrument as any one time. As such, a doctor can use a single tool to perform multiple functions, and thus reduce time spent looking for and/or retrieving the appropriate tool.
