Surgical Mallet for Simultaneous Positioning and Imaging of Biopsy Needles

SUMMARY

• Surgical biopsy needles are traditionally inserted by hand or with a mallet and the positioning of the needle is then verified and adjusted using periodic X-ray or CT imaging. However, imaging cannot be done through the surgical mallet or surgeon’s hand, which means the needle must be positioned blindly. This blind needle positioning prolongs procedure times and increases patient and provider exposure to radiation. 
• The inventors developed a novel surgical mallet design with a mallet head center that is translucent to X-Ray imaging. This allows for biopsy needles to simultaneously be positioned in place and imaged, eliminating the trial and error associated with biopsy needle placement. The invention also reduces patient exposure to unnecessary radiation.
• The inventors constructed a prototype of the surgical mallet using polycarbonate for the head center and simulated X-ray imaging of a target area in the spine through the translucent mallet center.
