Abstract

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.

Claims

1. A medical instrument, comprising:

a single elongated holding apparatus having a first end and a second end the holding apparatus being adapted to be held by a user when used by the user;

a second elongated holding apparatus having a first end and a second end, the second end of the second holding apparatus being operationally coupled to the second end of the holding apparatus;

a first medical head operationally coupled to the holding apparatus so that the first medical head extends from the first end of the holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use;

a fourth medical head corresponding to the first medical head and being operationally coupled to the second holding apparatus so that the forth medical head extends from the first end of the second holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use, wherein the fourth medical head is adapted to be used in conjunction with the first medical head;

a second medical head operationally coupled to the holding apparatus so that the second medical head extends from the first end of the holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use; and

a fifth medical head corresponding to the first medical head and being operationally coupled to the second holding apparatus so that the fifth medical head extends from the first end of the second holding apparatus when in use and retracts into a position such that no portion of the fifth medical head extends beyond the first end of the second holding apparatus when not in use, wherein the fifth medical head is adapted to be used in conjunction with the second medical head,

wherein a maximum of one of the medical heads extends from the first end of a corresponding holding apparatus at any time, and

wherein the first and fourth medical heads operate together as a clamp and wherein the second and fifth medical heads operate together as an alternately configured clamp, and wherein the first and second medical heads are slidably coupled to the holding apparatus.

2. The instrument of claim 1, further comprising a third medical head operationally coupled to the holding apparatus so that the third medical head extends from the first end of the holding apparatus when in use and retracts into the first end of the holding apparatus when not in use.

3. The instrument of claim 2, wherein the first medical head, the second medical head, and the third medical head retract into the first end of the holding apparatus when not in use and wherein the fourth medical head and the fifth medical head retract into the first end of the second holding apparatus when not in use.

4. The instrument of claim 1, wherein the first medical head retracts into the first end of the holding apparatus when not in use, and wherein the second medical head retracts into the first end of the holding apparatus when not in use.

5. The instrument of claim 1, wherein the medical instrument is a forceps.

6. A tool, comprising:

first and second elongated holding apparatuses, each holding apparatus having a first end and a second end, the apparatuses being operationally coupled at the second ends the first and second holding apparatuses being adapted to be held by a user when used by the user;

a pair corresponding first heads, one first head being slidably coupled to each of the holding apparatus so that each first head extends from the first end of the corresponding holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use, wherein the first heads operate together as a clamp; and

a pair corresponding second heads different from the first heads, one second head being slidably coupled to each of the holding apparatus so that each second head extends from the first end of the corresponding holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use, second heads operate together as an alternately configured clamp,

wherein a maximum of one of the heads extends from the first end of a corresponding holding apparatus at any time.

7. The tool of claim 6, wherein the tool is a medical instrument.

8. The tool of claim 7, wherein the medical instrument is a forceps.

9. The tool of claim 6, wherein the first head and the second head retract into the first end of the holding apparatus when not in use.

10. The tool of claim 6, further comprising a third head slidably coupled to each of the holding apparatus so that each first head extends from the first end of the corresponding holding apparatus when in use and retracts into a position such that no portion of the second medical head extends beyond the first end of the holding apparatus when not in use.

11. The tool of claim 10, wherein each of the first heads retracts into the first end of the corresponding holding apparatus when not in use, and wherein each of the second heads retracts into the first end of the corresponding holding apparatus when not in use, and wherein the third head retracts into the first end of the holding apparatus when not in use.
