Instruments for interspinous or interlaminar stabilization devices
Surgical instruments to properly implant interspinous/interlaminar stabilization devices, and instrumentation kits containing these instruments are provided. These surgical instruments may be configured to be disposable, or for single patient use, and therefore do not require resterilization for reuse, thus reducing risk of infection as a result of reuse and logistical costs associated with these resterilization procedures.
1. An instrument system for use with an interspinous or interlaminar stabilization device, comprising:
a handle component; and
a head component releasably attachable to the handle component, the head component having dual functioning ends, a first end being configured for interspinous, interlaminar or anatomical space measurement between adjacent vertebrae, and a second, opposed end being configured for attachment to an interspinous or interlaminar stabilization device for placement within the measured anatomical space;
wherein the head component may be attached at either of the dual functioning ends to the handle component.
2. The system of claim 1 , wherein the handle component comprises a grip and an elongate attachment stem.
3. The system of claim 2 , wherein the head component comprises an opening at either dual functioning end to receive the elongate attachment stem.
4. The system of claim 2 , wherein the elongate attachment stem further comprises a groove, detent, aperture or scored section.
5. The system of claim 4 , wherein the head component further comprises a spring tongue for engagement with the groove, detent, aperture, or scored section of the elongate attachment stem.
6. The system of claim 2 , wherein the handle component comprises an expansion pin for attachment to the elongate attachment stem.
7. The system of claim 6 , wherein the head component has an adjustable height midsection and is configured to receive the expansion pin of the handle component.
8. The system of claim 1 , wherein the head component further comprises rails at the second, opposed end.
9. The system of claim 1 , further comprising a series of head components of varying size.
10. The system of claim 1 , further being formed from a medical grade disposable material.
11. The system of claim 10 , wherein the medical grade disposable material comprises a polymeric material.
12. The system of claim 1 , further including visualization markers on the head component.
13. The system of claim 1 , wherein the handle component attaches to the head component at a fixed angle.
14. The system of claim 1 , wherein the handle component is angularly adjustable.
15. The system of claim 1 , wherein the handle is adjustable in length.
16. An instrument for use with an interspinous or interlaminar stabilization device, comprising:
a bending and crimping unit having dual functioning compression ends, a first end being configured for crimping together wings of an interspinous or interlaminar stabilization device, and a second, opposed end being configured for spreading apart wings of an interspinous or interlaminar stabilization device, the unit being configured to exert force against the wings of the device at either function end upon deployment, and
handles for deployment of the unit;
wherein the unit is configured to simultaneously crimp at its first end and bend at its second end.
17. The instrument of claim 16 , wherein the bending and crimping unit is configured to hold onto the interspinous or interlaminar stabilization device at either functioning end.
18. The instrument of claim 16 , further being formed of a medical grade disposable material.
19. The instrument of claim 18 , wherein the medical grade disposable material comprises a polymeric material.
20. The instrument of claim 16 , wherein the unit is configured to exert uniform force against the wings of the interspinous or interlaminar stabilization device.
21. An instrumentation kit for use with an interspinous or interlaminar stabilization device, comprising:
a sterile enclosure containing:
a handle component;
one or more head components releasably attachable to the handle component, each of the head components having dual functioning ends, a first end being configured for interspinous, interlaminar or anatomical space measurement between adjacent vertebrae, and a second, opposed end being configured for attachment to an interspinous or interlaminar stabilization device for placement within the measured anatomical space; and
a bending and crimping instrument having dual functioning compression ends, a first end being configured for crimping together wings of an interspinous or interlaminar stabilization device, and a second, opposed end being configured for spreading apart wings of an interspinous or interlaminar stabilization device, and handles for deployment of the instrument.
22. The kit of claim 21 , wherein the one or more head components comprises a series of head components of incrementally increasing size.
23. The kit of claim 21 , wherein the head component may be attached at either of the dual functioning ends to the handle component.
24. The kit of claim 21 , further comprising at least one interspinous or interlaminar stabilization device contained within the sterile enclosure.
25. The kit of claim 21 , further comprising a set of implantable device trials contained within the enclosure.
26. The kit of claim 21 , wherein the kit comprises a rigid bottom tray including raised walls corresponding in shape to the components and instruments.
27. The kit of claim 26 , further including a transparent top cover for displaying the contents of said kit.
28. The kit of claim 21 , further comprising an outer enclosure containing the sterile enclosure.
29. The kit of claim 21 , wherein the components and instrument are formed from a medical grade disposable material.
30. The kit of claim 29 , wherein the medical grade disposable material comprises a polymeric material.
