Abstract

An apparatus for inserting implants in a bone comprising a frame having a cartridge receiving chamber and a barrel. A cartridge defining a plurality of chambers is positioned in the cartridge receiving chamber so the chambers are selectively alignable with a longitudinal passage of the barrel. At least one instrument is positioned in one of the chambers, and a plurality of implants is positioned in the other chambers. A drive assembly is engageable with the instrument and the implants. The drive assembly is slidably and rotatably disposed in the frame and is moveable between a retracted position, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants, and an extended position wherein the drive assembly extends through the chamber to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel.

First claim

What is claimed is:

1. An apparatus for inserting implants in a bone, comprising:
a frame having a cartridge receiving chamber and a barrel, the barrel having a sidewall, a proximal end, a distal end, and a longitudinal passage extending through the barrel from the proximal end to the distal end;
a single cartridge defining a plurality of chambers extending through the cartridge in a parallel relationship to one another, the cartridge positioned in the cartridge receiving chamber of the frame so as to be movable relative to the barrel in a way that each of the chambers is selectively alignable with the longitudinal passage of the barrel;
at least one instrument positioned in a selected one of the chambers of the cartridge, the instrument configured for making a hole in the bone;
a plurality of implants positioned in selected ones of the chambers of the cartridge, each of the implants configured to be fixed within the hole formed in the bone by the instrument;
the barrel being configured to receive and position a selected instrument or implant for use at a distal end of the barrel; and
a drive assembly having a proximal end, a distal end and a longitudinal axis, the longitudinal axis aligned with the longitudinal passage extending through the barrel, the distal end of the drive assembly being engageable with the instrument and the implants, the drive assembly being slidably and rotatably disposed in the frame in a way that the drive assembly is moveable between a retracted position wherein the drive assembly is positioned to permit the cartridge to be moved so as to align a selected one of the instrument or the implant with the longitudinal passage of the barrel, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants positioned within the chamber aligned with the longitudinal passage of the barrel, and an extended position wherein the drive assembly is extended through the chamber aligned with the longitudinal passage of the barrel to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel where the drive assembly is rotatable to apply a rotational force to the selected one of the instrument or the implant.

2. The apparatus of claim 1 , wherein the drive assembly includes a driver having a proximal end and a distal end, and wherein the distal end of the driver is engageable with the instrument in a way that the instrument is moveable from the distal end of the barrel to the chamber aligned with the longitudinal passage of the barrel upon moving the driver from the extended position to the retracted position.

3. The apparatus of claim 1 , wherein the distal end of the driver has a first tip portion matingly engageable with the instrument and a second tip portion matingly engageable with the implant, wherein the second tip portion extends from the first tip portion, and wherein the first tip portion and the second tip portion are different in size.

4. The apparatus of claim 3 , wherein the first tip portion and the second tip portion are different in shape.

5. The apparatus of claim 1 , wherein the at least one instrument is defined further as a plurality of instruments, each of the instruments being positioned in a selected one of the chambers of the cartridge, and wherein one of the instruments is an awl, one of the instruments is a drill bit, and one of the instruments is a tap.

6. The apparatus of claim 1 , wherein the implants are pedicle screws.

7. The apparatus of claim 1 , wherein the drive assembly includes a driver and a drive shaft, and wherein the driver is connected to the drive shaft in a telescoping relationship such that the driver is positionable between a retracted position and an extended position relative to the drive shaft.

8. An apparatus for inserting implants in a bone, comprising:
a frame having a cartridge receiving chamber and a barrel, the barrel having a sidewall, a proximal end, a distal end, and a longitudinal passage extending through the barrel from the proximal end to the distal end;
a single cartridge defining a plurality of chambers extending through the cartridge in a substantially parallel relationship to one another, the cartridge positioned in the cartridge receiving chamber of the frame so as to be movable relative to the barrel in a way that each of the chambers is selectively alignable with the longitudinal passage of the barrel;
a drill bit positioned in one of the chambers of the cartridge, the drill bit having an instrument head and an instrument shaft configured for making a hole in the bone;
a plurality of screws positioned in selected ones of the chambers of the cartridge, each of the screws having an implant head and an implant shaft configured to be implanted in the bone; and
a drive assembly having a proximal end and a distal end, the distal end of the drive assembly being engageable with the drill bit and the screws, the drive assembly slidably and rotatably disposed in the frame in a way that the drive assembly is moveable between a retracted position wherein the drive assembly is positioned to permit the cartridge to be moved so as to align a selected one of the drill bit and the screws with the longitudinal passage of the barrel, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the drill bit and the screw positioned within the chamber aligned with the longitudinal passage of the barrel, and an extended position wherein the drive assembly is extended through the chamber aligned with the longitudinal passage of the barrel to transport the selected one of the drill bit and the screw from the chamber to the distal end of the barrel where the drive assembly is rotatable relative to the barrel to apply a rotational force to the selected one of the drill bit and the screw.

9. The apparatus of claim 8 , wherein the drive assembly includes a driver having a proximal end and a distal end and wherein the distal end of the driver is engageable with the drill bit in a way that the drill bit is moveable from the distal end of the barrel to the chamber aligned with the longitudinal passage of the barrel upon moving the driver from the extended position to the retracted position.

10. The apparatus of claim 8 , wherein the drive assembly includes a driver having a proximal end and a distal end and wherein the distal end of the driver has a first tip portion matingly engageable with the instrument and a second tip portion matingly engageable with the implant, wherein the second tip portion extends from the first tip portion, and wherein the first tip portion and the second tip portion are different in size.

11. The apparatus of claim 10 , wherein the first tip portion and the second tip portion are different in shape.

12. The apparatus of claim 8 , further comprising an awl being positioned in a selected one of the chambers of the cartridge.

13. The apparatus of claim 8 , wherein the screws are pedicle screws.

14. The apparatus of claim 8 , further comprising anchoring spikes connected to and extending from the distal end of the barrel.

15. The apparatus of claim 8 , wherein the drive assembly includes a driver and a drive shaft, and wherein the driver is connected to the drive shaft in a telescoping relationship such that the driver is positionable between a retracted position and an extended position relative to the drive shaft.

16. An apparatus for inserting implants in a bone, comprising:
a frame having a cartridge receiving chamber and a barrel, the barrel having a s
