Abstract

An impact or extension handle for a needle assembly such as a Jamshidi needle can include an attachment portion and a handle portion. The impact or extension handle can also include an impact strikeplate. The attachment portion is configured to couple to the Jamshidi needle. A user can use the impact or extension handle to manipulate the position or angle of the needle assembly. A user can tap a mallet or similar instrument on the impact strikeplate to drive the needle assembly into a target location in a patient'"'"'s body. The impact or extension handle can allow the user to hold his or her hands out of the way of equipment used during the procedure and away from potentially harmful radiation from imaging equipment used during the procedure.

Claims

1-19. -19. (canceled)

20. An impact handle for use with a needle assembly, comprising:

an attachment portion configured to couple to the needle assembly;

a handle portion extending from the attachment portion and configured to be gripped in use, wherein the handle portion is movable relative to the attachment portion; and

an impact strikeplate, the impact strikeplate configured to be struck with an instrument in use and configured to transfer forces from the instrument to the needle assembly to drive at least a portion of the needle assembly into bone.

21. The impact handle of claim 20, wherein the handle portion is coupled to the attachment portion in a foldable arrangement.

22. The impact handle of claim 20, wherein the handle portion is rotatable relative to the attachment portion.

23. The impact handle of claim 20, wherein the attachment portion and the impact strikeplate are a single piece.

24. The impact handle of claim 20, wherein the impact handle comprises a locking mechanism configured to secure the attachment portion to the needle assembly in a locked position.

25. The impact handle of claim 20, wherein the impact handle comprises a recess configured to receive a portion of the needle assembly.

26. A method of driving a Jamshidi needle into a target location in a body of a patient, utilizing the impact handle of claim 20, comprising:

coupling the impact handle to the needle assembly; and

tapping the impact strikeplate with an instrument to drive the needle assembly into the target location.

27. A kit comprising:

the impact handle of claim 20; and

the needle assembly, the needle assembly comprising;

a cannula shaft; and

a cannula handle coupled to a proximal-most end of the cannula shaft.

28. The kit of claim 27, wherein a width of the cannula handle extends beyond a width of the cannula shaft in a plane offset from a longitudinal axis of the cannula shaft

29. The kit of claim 27, further comprising a stylet having a sharp distal tip, wherein the stylet is configured to be disposed in a lumen of the cannula shaft.

30. The kit of claim 29, wherein the stylet comprises a stylet shaft and a stylet handle, wherein a width of the stylet handle extends beyond a width of the stylet shaft in a plane offset from a longitudinal axis of the stylet shaft.

31. An impact handle for use with a needle assembly, comprising:

an attachment portion configured to couple to the needle assembly;

a handle portion configured to be gripped in use; and

an impact strikeplate, the impact strikeplate configured to be struck with an instrument in use and configured to transfer forces from the instrument to the needle assembly to drive at least a portion of the needle assembly into bone, wherein the handle portion is movable relative to the impact strikeplate.

32. The impact handle of claim 31, wherein the handle portion is coupled to the impact strikeplate in a foldable arrangement.

33. The impact handle of claim 31, wherein the handle portion is rotatable relative to impact strikeplate.

34. The impact handle of claim 31, wherein the impact handle comprises a recess configured to receive a portion of the needle assembly.

35. A method of driving a Jamshidi needle into a target location in a body of a patient, utilizing the impact handle of claim 31, comprising:

coupling the impact handle to the needle assembly; and

tapping the impact strikeplate with an instrument to drive the needle assembly into the target location.

36. A kit comprising:

the handle of claim 31; and

the needle assembly, the needle assembly comprising;

a cannula shaft; and

a cannula handle coupled to a proximal-most end of the cannula shaft.

37. The kit of claim 36, wherein a width of the cannula handle extends beyond a width of the cannula shaft in a plane offset from a longitudinal axis of the cannula shaft

38. The kit of claim 36, further comprising a stylet having a sharp distal tip, wherein the stylet is configured to be disposed in a lumen of the cannula shaft.

39. The kit of claim 38, wherein the stylet comprises a stylet shaft and a stylet handle, wherein a width of the stylet handle extends beyond a width of the stylet shaft in a plane offset from a longitudinal axis of the stylet shaft.
