Claims
- 1. A bone tissue harvesting device comprising:
a cutting tool having a longitudinal axis and including a rotatable shaft with proximal and distal ends and an axial bore extending therethrough, and a cutting head coupled to the shaft and having a through-hole operably associated with the axial bore such that bone removed by the cutting head passes from the through-hole to the bore; a drive element for rotating the shaft about the longitudinal axis and including a handle for manually operating the device; and a container, having a central axis, detachably mounted to the drive element and operably associated with the cutting tool such that the central axis of the container is co-linear with the longitudinal axis of the cutting tool, wherein the container is under vacuum such that negative pressure suctions removed bone from the through-hole to the container through the axial bore, and wherein the handle is configured and arranged such that the drive element, cutting tool and container are movable by the handle.
- 2. The device of claim 1 wherein the proximal end of the shaft opens into the container.
- 3. The device of claim 2 wherein the container remains fixed with respect to the longitudinal axis.
- 4. The device of claim 3 wherein the container includes a bearing operably associated with the shaft for mounting the container on the shaft of the cutting tool.
- 5. The device of claim 4 wherein the bearing is a gasket sealed bearing.
- 6. The device of claim 2 further comprising an airtight seal between the shaft and the container such that the proximal end of the shaft opens into the container and is isolated from the environment.
- 7. The device of claim 1 wherein the container further comprises a nozzle connection for connection to a vacuum line.
- 8. The device of claim 1 wherein the container comprises a separation element for separating the bone tissue from the air stream.
- 9. The device of claim 8 wherein the separation element is a filter.
- 10. The device of claim 1 wherein the shaft includes a flexible portion.
- 11. The device of claim 10 wherein the flexible portion of the shaft includes a metal strip wound in a spiral.
- 12. The device of claim 10 wherein a tube is located with the bore of the shaft and the tube is made of rubber or plastic.
- 13. The device of claim 10 wherein the shaft is made of a metal tube.
- 14. The device of claim 1 wherein the cutting head comprises a cylinder having proximal and distal ends with a hollow space therethrough, the distal end having a drill tip with at least one cutting edge and at least one through-hole extending radially from the central longitudinal axis for conveying removed bone tissue to the bore of the shaft.
- 15. The device of claim 14 wherein the drill tip has a shape like a sector of universal ball joint.
- 16. The device of claim 1 wherein the drive element is a universal drilling machine.
