Abstract

A method and device for controlling the pain of a periodontal ligament injection, and other minor medical and dental procedures. The device desensitizes the tissues utilizing cold, vibration, or both. The method is useful for injections, small biopsies, intraosseous drilling, blood sampling, and so on.

Claims

1. A method for injecting a medicament into the periodontal ligament of a tooth comprising the steps of drilling into the ligament with a drill bit having a central bore, injecting medicament through said bore and into the ligament, and removing said bit from the ligament.

2. A tissue puncture method comprising the steps of supporting a sharp with respect to a topical press, vibrating and/or cooling a tissue puncture area with said topical press, or cover thereof, puncturing the tissues with said sharp at a puncture point within the vibrating and/or cooled puncture area, and withdrawing said sharp from the puncture point.

9. The methods of claims 2, 3, 4, 5, 7, and 8, wherein the tissue cooling device utilizes a vapocoolant with a boiling point between −

1 C and −

30 C.

10. The methods of claim 9, wherein the coolant is 1,1,1,2,3,3,3-heptafluoropropane

11. The method of claim 9, wherein the coolant is 1,1,1,3,3,3-hexafluoropropane

12. The method of claims 2, 3, 4, and 5, wherein said cover is a bandage.

13. The method of claim 12, wherein said bandage has adhesive on two sides.

3. A tissue puncture method comprising the steps of supporting a sharp with respect to a topical press, said topical press having an opening therethrough for passage of said sharp, directly vibrating and/or cooling a tissue puncture point with said topical press or cover thereof, puncturing the vibrating and/or cooling tissues at the puncture point with said sharp, and withdrawing said sharp from the tissues.

4. A tissue puncture method comprising the steps of supporting a sharp with respect to a topical press surface or cover thereof, directly vibrating and/or cooling a tissue puncture point with said topical press or cover thereof, puncturing said topical press surface or cover thereof, puncturing the vibrating and/or cooling tissue puncture point with said sharp, and withdrawing said sharp from the tissues.

5. A tissue puncture method comprising the steps of directly vibrating and/or cooling a tissue puncture point with a topical press or cover thereof, puncturing the vibrating and/or cooling the tissue puncture point with a sharp, and withdrawing said sharp from the tissues.

6. A tissue puncture method comprising the steps of vibrating a tissue area which substantially encompasses a puncture point, puncturing the vibrating tissue area at the puncture point with a sharp, and withdrawing said sharp from the puncture point.

7. A tissue puncture method comprising the steps of cooling a tissue area which substantially encompasses a puncture point utilizing a coolant-absorbent surface, puncturing the cooling puncture point with a sharp, and withdrawing said sharp from the puncture point.

8. A tissue puncture method comprising the steps of cooling a tissue puncture area with a cold topical press or cover thereof, inserting a sharp into and through said topical press and into the cooling tissues of the puncture area, and withdrawing said sharp from the tissues.
