Abstract
A device for expedited reaming of a medullary canal having a detachable reaming head is disclosed. The device includes a reamer head connected at the distal end of a rotatable drive shaft. The reamer head has a cutting head with a plurality of blades and flutes therebetween at a first end and a plurality of resilient arms at a second end. The device may also includes an aspiration tube which fits over the rotatable drive shaft and a reamer head retainer which rotatably engages the reamer head. In addition, the reamer head may be detached from the reamer device for future re-use by using a reamer head removing device.
Claims (14)
1. A device for reaming a medullary canal of a bone comprising:
a rotatable drive shaft having proximal and distal ends, the proximal end configured nd adapted to connect to a drive element to rotate the drive shaft; and a reamer head coupled to the distal end of the drive shaft, to rotate the reamer head, aid reamer head comprising:
a tubular shank having a longitudinal axis and a plurality of resilient arms for engaging the distal end of the drive shaft; and a cutting head coupled with the shank and having a plurality of blades and flutes therebetween for cutting and reaming of bone.
a rotatable drive shaft having proximal and distal ends, the proximal end configured nd adapted to connect to a drive element to rotate the drive shaft; and a reamer head coupled to the distal end of the drive shaft, to rotate the reamer head, aid reamer head comprising:
a tubular shank having a longitudinal axis and a plurality of resilient arms for engaging the distal end of the drive shaft; and a cutting head coupled with the shank and having a plurality of blades and flutes therebetween for cutting and reaming of bone.
2. The device of claim 1, wherein the drive shaft and reamer head each has a cannulation, with the drive shaft cannulation aligning with the reamer head cannulation when the tubular shank and resilient arms are engaged with the drive shaft to form a center channel through the device.
3. The device of claim 2, further comprising:
an aspiration tube for removing cut material generated by the reamer head, the aspiration tube having a manifold assembly at a proximal end and a lumen configured and dimensioned to receive the drive shaft; and a reamer head retainer having proximal and distal ends and configured and dimensioned at a proximal end to connect to a distal end of the aspiration tube and configured and dimensioned at a distal end to receive the reamer head.
