Abstract

A hand-held transducer probe is overlapped with elastomeric material for improving the friction and softness of the grip of the probe. The elastomeric material comprises a biocompatible material having a tear strength in excess of 110 pounds per inch and a hardness level less than approximately shore A 80. Also disclosed is a method of producing a hand-held transducer probe having an improved grip comprising the steps of assembling an acoustic array and cable assembly; attaching a handle portion over aid acoustic array and cable assembly; and attaching an elastomeric material over at least a portion of said handle portion.

Claims

1. A hand-held ultrasound transducer probe comprising:

a housing having an ultrasound transducer mounted therein, said housing including;

a handle portion for being grasped by the user to manipulate said transducer probe; and

an elastomeric material overlapping at least a portion of said handle portion, said elastomeric material being a separate component from said handle portion and being attached to said handle portion;

wherein said elastomeric material provides increased friction and a softer grip for grasping and manipulating said handle portion than is provided by said handle portion alone.

2. The ultrasound transducer probe as recited in claim 1 wherein said handle portion has gripping positions and said elastomeric material is attached to at least a portion of said gripping positions.

3. The ultrasound transducer probe as recited in claim 2 wherein said elastomeric material is selected from the group consisting of polyolefin based materials, rubber based materials, polyurethane based materials and blends of these materials.

4. The ultrasound transducer probe as recited in claim 3 wherein said elastomeric material is selected from the group further consisting of polyvinylchloride, silicone rubber, and neoprene-type materials, and blends of these materials.

5. The ultrasound transducer probe as recited in claim 1 wherein said elastomeric material is biocompatible, has a die B dumbbell tear strength in excess of 110 pounds per inch, and has a hardness level less than approximately shore A 80.

6. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material is colorable.

7. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material has a tensile strength greater than 700 pounds per square inch.

8. The ultrasound transducer probe as recited in claim 5 wherein said hardness level of said elastomeric material is within the range of approximately shore A 40 to 70.

9. The ultrasound transducer probe as recited in claim 5 wherein two or more distinct sections of said elastomeric material are attached to said handle portion.

10. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material has a thickness within the range of approximately 0.5-10 mm.

11. The ultrasound transducer probe as recited in claim 10 wherein said elastomeric material has a thickness within the range of approximately 1-5 mm.

12. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material is a self-adhesive elastomeric pad.

13. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material is a self-adhesive tape.

14. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material further comprises a thermally activated adhesive.

15. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material is an elastic band.

16. The ultrasound transducer probe as recited in claim 5 wherein said elastomeric material is a heat shrink band.

17. The ultrasound transducer probe as recited in claim 16 wherein said heat shrink band further comprises heat activated adhesive for bonding said heat shrink band to said ultrasound transducer probe.

18. The ultrasound transducer probe as recited in claim 5 wherein said transducer probe further comprises a strain relief and said elastomeric material is attached in one substantially continuous piece covering a substantial portion of said handle portion and said strain relief.

19. The ultrasound transducer probe as recited in claim 1 wherein said handle portion comprises a hard, durable polymeric material.

20. The ultrasound transducer probe as recited in claim 19 wherein said handle portion is selected from the group consisting of polyethersulfone, polycarbonate, polyurethane, polysulfone, PET and families thereof.

21. A method of producing a hand-held ultrasound transducer probe comprising the steps:

assembling an acoustic array and cable assembly;

attaching a handle portion over said acoustic array and cable assembly; and

attaching an elastomeric material over at least a portion of said handle portion, with an adhesive being employed between said handle portion and said elastomeric material to assist in securing said elastomeric material to said handle portion,

wherein said elastomeric material provides increased friction and a softer grip for holding said transducer probe than is provided by said handle portion alone.

22. The method of claim 21 wherein said elastomeric material is attached to said handle portion by thermoplastic overmolding.

23. The method of claim 21 wherein said elastomeric material is attached to said handle portion by casting.

24. The method of claim 21 wherein said handle portion has gripping positions and said elastomeric material are attached over at least a portion of said gripping positions.

25. The method of claim 24 wherein said handle portion is formed with indentations at said gripping positions for assisting in securing said elastomeric material to said gripping positions.

26. The method of claim 25 wherein said handle portion has an inside surface and an outside surface, said outside surface including said gripping positions, said elastomeric material being in a liquid phase when said elastomeric material is applied to said gripping positions of said handle portion, said handle portion being formed with perforations in said gripping positions for allowing said elastomeric material to pass through Said perforations when said liquid elastomeric material is applied to said gripping positions for allowing said elastomeric material to solidify on both the inside and outside surfaces of said handle portion for assisting in securing said elastomeric material to said handle portion.

27. The method of claim 21 wherein said elastomeric material is attached to said handle portion before said handle portion is attached to said acoustic array and cable assembly.

28. The method of claim 21 wherein said handle portion is produced over said acoustic array and cable assembly.

29. The method of claim 21 wherein said adhesive is a polyurethane.

30. The method of claim 29 wherein said polyurethane is a heat activated adhesive.
