Abstract

A hand-held surgical instrument is well-suited to fluoroscopic x-ray imaging. In needle-positioning forceps, an instrument according to the invention preferably exhibits a length of 8 inches or greater, and is constructed substantially from a radiolucent material, thereby enabling a user to navigate the article without being exposed to the beam. The radiolucent material may include a plastic such as a thermoplastic polymer or carbon fiber, and may be presterilized and disposable for one-time use. In the preferred embodiment, the length of the instrument is on the order of 12 inches or thereabouts, and is lordotically shaped for better conformance to patient curvature. The distal tip of the instrument, which is sufficiently strong to reliably grip a needle, may include a needle-dimensioned indent and/or a pair of opposing resilient pads. A radiopaque pointer may be provided to indicate the distal tip, and the pointer may be provided in the form of a removable adhesive strip. A central finger stop or pad may be located between the proximal and distal ends of the instrument, and one or more needle-bending holes may be provided.

Claims

1. Forceps for use during x-ray beam imaging, comprising:

a pair of substantially radiolucent scissoring elements, each having a proximal, finger-receiving hole and distal end with an opposing portion of a grip for holding an article to be navigated;

the scissoring elements crossing at an interconnecting hinge region including an upper finger-positioning area;

the distance between the finger-receiving holes and the finger-positioning area being substantially less than the distance between the finger-positioning area and the distal end; and

wherein the scissoring elements each have a length of 8 inches or greater, enabling a user to navigate the article without being exposed to the x-ray beam.

2. The forceps of claim 1, wherein the length of the scissoring elements are 12 inches or thereabouts.

3. The forceps of claim 1, wherein the scissoring elements are sufficiently strong to enable the distal end to reliably grip a needle.

4. The forceps of claim 3, wherein the distal end further includes a needle-dimensioned indent.

5. The forceps of claim 3, wherein the distal end further includes a pair of opposing resilient pads.

6. The forceps of claim 1, wherein the radiolucent material includes a plastic, thermopolymer, or carbon fiber.

7. The forceps of claim 1, further including a radiopaque pointer indicating the distal tip.

8. The forceps of claim 7, wherein the pointer is on a removable adhesive strip.

9. The forceps of claim 1, further including a central finger stop or pad associated with the upper finger-positioning area.

10. The forceps of claim 1, further including one or more needle-bending holes.

11. The forceps of claim 1, wherein the scissoring elements are curved upwardly between the finger-receiving holes and the upper finger-positioning area.

12. The forceps of claim 1, including sterilized packaging for a disposable, one-time use.
