Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
Apparatus for extracting bone material from an extraction site, comprising: a housing defining a cavity and a passageway for transporting bone material to a collection device, the passageway having a distal end, in communication with a first end of a suction tube, and a proximal end; the housing further defining a second passageway for passing irrigation fluid to the extraction site, the apparatus further comprising a source of irrigation fluid in fluid communication with the second passage; a flexible shaft with a proximal end disposed in the cavity and a distal end extending beyond the cavity; an abrading head attached to the distal end of the shaft; a conduit extending through the shaft and abrading head, the conduit fluidly communicating with the passageway; and an actuator coupled to the proximal end of the shaft, wherein the shaft is free to deflect radially with respect to a connection to the actuator.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
16 words
The apparatus of claim 1 , in which the flexible shaft comprises a tightly wound spring.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 , in which the flexible shaft is prestressed to bend in a predetermined direction.
Claim 5
Dependent Claim
20 words
The apparatus of claim 1 , in which the abrading head comprises a bur and the actuator rotates the shaft.
Claim 6
Dependent Claim
26 words
The apparatus of claim 1 , in which the abrading head comprises a bur and the actuator causes the shaft to move in a reciprocating motion.
Claim 7
Dependent Claim
36 words
The apparatus of claim 1 , in which a drive member is disposed in the housing and is adapted for connection to the actuator, and the shaft second end is releasably connected to the drive member.
Claim 8
Dependent Claim
21 words
The apparatus of claim 1 , in which a second end of the suction tube is connected to a vacuum source.
Claim 9
Dependent Claim
21 words
The apparatus of claim 1 , in which the collection device comprises a container in fluid communication with the suction tube.
