5. The apparatus of claim 4, wherein the guide is tubular.
6. The apparatus of claim 4, wherein the guide is connected to the tool for movement along an arcuate path to a position in alignment with the angled passage of the receiver.
7. The apparatus of claim 4, wherein the tool comprises a connector adapted for connecting to the body of the receiver.
8. The apparatus of claim 1, further including a tubular guide for guiding a drilling element for forming an opening in one of the superior or inferior vertebrae.
9. The apparatus of claim 8, wherein the tubular guide is connected to the receiver in alignment with the angled passage.
10. An apparatus for use in connection with a procedure for connecting superior and inferior vertebrae using a receiver including at least one passage, comprising:
a tool adapted to be connected to the receiver for guiding a drilling element for forming an opening in one of the superior or inferior vertebrae.
11. The apparatus of claim 10, wherein the tool comprises a guide adapted for receiving the drilling element.
12. The apparatus of claim 11, wherein the guide is connected to the tool for movement along an arcuate path to a position in alignment with the angled passage of the receiver.
13. The apparatus of claim 10, wherein the tool includes a connector for connecting to the receiver in a manner that prevents relative rotation during use in forming the opening on one of the superior or inferior vertebrae.
14. The apparatus of claim 10, wherein the tool includes a connector for connecting to the receiver in a manner that allows relative rotation after forming the opening on one vertebrae to form an opening in the other vertebra.
15. An apparatus for use in connection with a procedure for connecting superior and inferior vertebrae, comprising:
a receiver for positioning between the superior and inferior vertebrae, the receiver adapted for positioning between the superior vertebra and the inferior vertebra; and
a tool adapted to be connected to the receiver for guiding a drilling element for forming an opening in one of the superior or inferior vertebrae.
16. The apparatus of claim 15, wherein the receiver includes at least one passage adapted for receiving a fastener, the passage extending at an angle relative to a first surface of the receiver for positioning adjacent to the superior vertebra and a second surface of the receiver for positioning adjacent to the inferior vertebra.
17. The apparatus of claim 15, wherein the tool comprises a guide adapted for receiving the drilling element.
18. The apparatus of claim 17, wherein the guide is connected to the tool for movement along an arcuate path to a position in alignment with the angled passage of the receiver.
19. The apparatus of claim 15, wherein the tool includes a connector for connecting to the receiver in a manner that prevents relative rotation during use in forming the opening on one of the superior or inferior vertebrae.
20. The apparatus of claim 15, wherein the tool includes a connector for connecting to the receiver in a manner that allows relative rotation after forming the opening on one vertebrae to form an opening in the other vertebra.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cap structure comprising a cap body, a glass and a connecting unit for connecting the cap body with the glass, wherein:
the cap body has a peak section outward extending from a part of the periphery of the cap body, at least one magnetic member being inlaid in the peak section, the magnetic member being movable toward a front edge of the peak section;
the connecting unit includes a pivot seat and a pivot block pivotally connected with the pivot seat, at least one magnetic member being disposed in one end of the pivot seat opposite to the pivot block, whereby the magnetic member of the peak section and the magnetic member of the pivot seat can attract each other; and
the glass is fixedly connected with one end of the pivot block opposite to the pivot seat.
2. The cap structure as claimed in claim 1, wherein the magnetic member in the peak section is a circular magnet, an elongated rectangular seat body being embedded in the peak section, the seat body having two wing sections on two sides for sewing the seat body in the peak section, the seat body being formed with two internal slide channels, two magnetic members being respectively placed in the slide channels and reciprocally slidable within the slide channels.
3. The cap structure as claimed in claim 1, wherein the magnetic members of the pivot seat are cylindrical magnetic bodies, the pivot seat having a plane face opposite to the pivot block, two dents being formed on the plane face, in which the magnetic members of the pivot seat are respectively fixedly accommodated.
4. The cap structure as claimed in claim 3, wherein the pivot seat has a substantially U-shaped pivot section facing the pivot block and the pivot block has a substantially T-shaped pivot section corresponding to the pivot section of the pivot seat, whereby the pivot section of the pivot block can be pivotally connected with the pivot section of the pivot seat.
5. The cap structure as claimed in claim 3, wherein the pivot seat has a substantially T-shaped pivot section facing the pivot block and the pivot block has a substantially U-shaped pivot section corresponding to the pivot section of the pivot seat, whereby the pivot section of the pivot block can be pivotally connected with the pivot section of the pivot seat.
6. The cap structure as claimed in claim 1, wherein one end of the pivot block is formed with a groove opposite to the pivot seat, in which an upper edge of the glass is inlaid, at least one screw being perpendicularly screwed into the groove to abut against the glass to fix the glass with the pivot block.
7. The cap structure as claimed in claim 6, wherein the pivot block has a boss in the middle of the groove, the upper edge of the glass being formed with a notch corresponding to the boss, whereby when the upper edge of the glass is inlaid in the groove, the boss is snugly fitted into the notch.
