The invention is an improved endodontic adapter for a sonic scaler consisting of a talon having a threaded end for insertion into the handle of the sonic scaler. A pair of downwardly pointed barbs protrudes radially from the side of the adapter for receiving an elastic ligature, which firmly holds the dental instrument such as file to the talon. The opposite end of the talon has a tapered shaft that receives an aperture drilled into the side of the dental instrument. The ligature is simply wrapped around the dental instrument on opposite sides of the talon and then the ends are wrapped around the downwardly pointing barbs.

An apparatus, comprising:a medical instrument having a handle, said handle having a transverse axis, said handle having an aperture defined therein coincident with said transverse axis; a mounting head having a shaft extending therefrom, said shaft adapted to be inserted into the aperture defined
1. An apparatus, comprising:a medical instrument having a handle, said handle having a transverse axis, said handle having an aperture defined therein coincident with said transverse axis; a mounting head having a shaft extending therefrom, said shaft adapted to be inserted into the aperture defined in said handle of said medical instrument; and, a ligature operatively connected to said mounting head, said ligature adapted to secure said medical instrument to said mounting head, said ligature being at least partially elastic, said handle of said medical instrument being positioned between said elastic ligature and a first frusto-conical section; wherein said mounting head is a single piece and further comprises said first frusto-conical section transitioning into a second frusto-conical section via a shelf, said first frusto-conical section having a first end with a diameter d1 and a second end with a diameter d2, said second frusto-conical section having a first end with a diameter d3 and a second end d4, wherein d1<d2<d3<d4. 2. The apparatus of claim 1, wherein said mounting head is steel.3. The apparatus of claim 1, wherein said mounting head is plastic.4. The apparatus of claim 1, wherein said ligature is an o-ring.5. A method for securing a medical instrument to a mounting head of a medical device, the method comprising the steps of:providing a medical instrument having a handle, said handle having a transverse axis, said handle having an aperture defined therein coincident with said transverse axis; and, said mounting head having a shaft extending therefrom, said shaft adapted to be inserted into the aperture defined in said handle of said medical instrument; inserting said shaft into the aperture of said medical instrument such that said medical instrument is substantially perpendicular to said mounting head; and securing said medical instrument to said mounting head with an elastic ligature, such that said medical instrument is positioned between the elastic ligature and a first frusto-conical section of said mounting head. 6. The method of claim 5, further comprising the step of:connecting said mounting head to a handle of said medical device. 7. The method of claim 5, wherein said elastic ligature is an o-ring.8. An apparatus, comprising:a medical instrument having a handle, the handle having a transverse axis, said handle having an aperture defined therein coincident with said transverse axis; and, a mounting head having a shaft extending therefrom, said shaft adapted to be inserted into the aperture defined in said handle of said medical instrument, wherein said mounting head is a single piece and further comprises a first frusto-conical section transitioning into a second frusto-conical section via a shelf, said first frusto-conical section having a first end with a diameter d1 and a second end with a diameter d2, said second frusto-conical section having a first end with a diameter d3 and a second end d4, wherein d1<d2<d3<d4, wherein said shaft is threaded and extends from said first frusto-conical section. 9. The apparatus of claim 8, wherein said mounting head further comprises a threaded shaft extending from said second frusto-conical section for insertion into an associated handle of a sonic unit.10. The apparatus of claim 8, further comprising an elastic ligature adapted to further secure said medical instrument to said shaft of said mounting head, so that said handle of said medical instrument is positioned between said elastic ligature and said first frusto-conical section.11. The apparatus of claim 10, wherein said elastic ligature is an o-ring.12. The apparatus of claim 10, wherein said elastic ligature is made from rubber.13. The apparatus of claim 8, wherein said mounting head further comprises a water relief hole defined therein.14. An apparatus, comprising:a mounting head having a shaft extending therefrom, said shaft adapted to be inserted into an aperture defined in an associated handle of a medical instrument, such that the medical instrument is substantially perpendicular to said mounting head, wherein said mounting head is a single piece and further comprises a first frusto-conical section transitioning into a second frusto-conical section via a shelf, such that said first frusto-conical section is laterally spaced from said second frusto-conical section, said first frusto-conical section having a first end with a diameter d1 and a second end with a diameter d2, said second frusto-conical section having a first end with a diameter d3 and a second end d4, wherein d1<d2<d3<d4, said shaft being threaded and extending from said first frusto-conical section.
