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.
