Abstract

A one-piece C-arm for use with X-ray diagnostic equipment included in cross-section two generally vertical sidewalls extending generally parallel to one another, an inner support wall connecting the sidewalls, and an outer support wall spaced-apart from the inner support wall and connecting the sidewalls. A pair of flanges extend outwardly from respective sidewalls, and toward one another to form at least one channel along an outer portion of the C-arm frame for receiving wheels or bearings to allow moveable mounting of the C-arm on diagnostic equipment.

Claims

1. A one-piece C-arm for use with x-ray diagnostic equipment comprising a frame formed of a single piece of material generally in a C shape with a cross-section which includes two spaced apart sidewalls, an inner support wall connecting the sidewalls, an outer support wall spaced apart from the inner support wall and connecting the sidewalls, and first and second flanges, each extending from a respective sidewall outwardly to an outer circumference of the C shape and then toward one another to form a channel between the flanges.

2. The C-arm of claim 1 wherein the outer support wall further comprises in cross-section a section between the sidewalls projecting generally away from the inner support wall and toward the flanges such that the projecting section and flanges form two channels adjacent the outside circumference.

3. The C-arm of claim 2 wherein the projecting section of the outer support wall comprises in cross-section two angled sections extending toward the outer circumference, and a substantially flat section disposed adjacent said outer circumference and connecting the angled sections.

4. The C-arm of claim 1 wherein the inner support wall is generally arch-shaped in cross-section, as it extends from one sidewall to the other.

5. The C-arm of claim 4 wherein the inner support wall comprises in cross-section two beveled sections extending toward one another from the sidewalls, and a center section connecting said beveled sections.

6. The C-arm of claim 1 further comprising

grooves formed in lateral sides of the sidewalls to extend circumferentially generally along the length of the C-arm, and

a plurality of clips for nesting in the grooves to hold a surgical drape/curtain adjacent to the frame member.

7. The C-arm of claim 6 wherein each of the clips comprise a resilient body formed generally C-shaped with two ends for fitting in respective grooves to bridge over the inner support wall.

8. The C-arm of claim 7 further comprising a surgical drape attached to the clips to extend generally along an inner circumference of the C-arm to cover the inner support wall.

9. The C-arm of claim 1 wherein the frame is formed of aluminum.

10. A one-piece C-arm for use with X-ray diagnostic equipment, comprising a frame defined by a single piece of material generally in a C shape, the frame including an C-shaped elongate hollow tube and first and second flanges, each flange extending from the tube outwardly to an outer circumference of the C-shaped frame and then toward one another, to form a channel for receiving bearings by which the C-arm is supported and rotated, each flange extending along the elongate hollow tube such that said channel extends at least half of the length of the elongate hollow tube.

11. The C-arm of claim 10 wherein the elongate hollow tube comprises a generally round cross-section.

12. The C-arm of claim 10 wherein the elongate hollow tube comprises a generally rectangular cross-section.

13. The C-arm of claim 10 wherein the elongate hollow tube comprises a generally triangular cross-section.
