Abstract

Disclosed is a bone graft harvesting device that includes a cutter section and a housing section secured to one another via a removable fastener, such as a manually operable screw. One of these sections includes a proximal end having a shaft configured for connection to a drill or other rotary tool, and the other may include a scoop for facilitation of removal of harvested bone from a patient. The cutter section and housing section may be separated from one another upon harvesting of bone from a patient to access harvested bone in a cavity of the housing.

First claim

What is claimed is:

1 . A bone graft harvesting device comprising an assembly of a cutter section and a separable housing section and a fastener securing the cutter section to the housing section, one of the housing section and cutter section comprising a proximal shaft, the cutter section and housing section defining therebetween a hollow bone-receiving chamber, said cutter section including an auger portion disposed at a distal end of the device, wherein the cutter section and housing section are joined at an interface that is an exterior interface along at least a portion of a path that extends from a proximal end of the assembly to the distal end of the assembly.

2 . The device of claim 1 , the fastener comprising a manually operable screw.

3 . The device of claim 1 , the proximal shaft being disposed on the housing section.

4 . The device of claim 3 , the cutter section including a scoop portion sized to fit inside the housing section when the cutter section and housing section have been separated.

5 . The device of claim 1 , the cutter section and housing section each provided with a keyed geometry proximal said distal end, the geometry of the cutter section being complementary to that of the housing section.

6 . The device according to claim 1 , said proximal shaft comprising an AO coupling.

7 . A method comprising providing the device of claim 1 , connecting said device to a rotary tool via said proximal shaft, harvesting bone from a patient, separating said cutter section from said housing section, and recovering harvested bone.

8 . A method according to claim 7 , the housing section comprising the proximal shaft, the method comprising separating the cutter section from the housing section while the proximal shaft remains connected to said rotary tool.

9 . A method comprising:
providing a bone harvesting device, the device comprising an assembly of a cutter section and a separable housing section and a fastener securing the cutter section to the housing section, the housing section comprising a proximal shaft, the device including a hollow bone-receiving chamber, said cutter section including an auger portion disposed at a distal end of the device, wherein the cutter section and housing section are joined at an interface that is an exterior interface along at least a portion of a path that extends from a proximal end of the assembly to the distal end of the assembly; connecting said device to a rotary tool via said proximal shaft; harvesting bone from a patient; separating said cutter section from said housing section, and recovering harvested bone from the housing section of the device while the proximal shaft remains connected to said rotary tool.
