Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
268 words
A disposable, single use curette blade comprising: an elongated, unitary body member having an integrally formed shank portion, juncture portion and cutter portion with said juncture portion being disposed intermediate said shank portion and said cutter portion to connect said shank portion to said cutter portion; said shank portion extending longitudinally from said juncture portion in one longitudinal direction and in the shape of a single band of material of a substantially uniform thickness, wherein only said shank portion of said curette blade extends in said one longitudinal direction beyond said juncture portion, said shank portion including means for cooperation with a handle to selectively, releasably retain said curette blade with respect to such a handle; said cutter portion having at least one edge which forms a sharp cutting edge; said cutter portion comprising a portion of said body member extending from said juncture portion as a generally arcuate means having a pair of end portions disposed adjacent said juncture portion and said at least one edge extending arcuately intermediate said pair of end portions such that said at least one edge forms an arcuate sharp cutting edge; one of said end portions being integrally formed with said juncture portion and the other of said end portions being fixed adjacent said juncture portion by a mechanical fastener means; and wherein said cutter portion is formed of a single band of material having a thickness defined by a maximum thickness of said band of material forming said cutter portion with said defined thickness substantially equal to said substantially uniform thickness of said band of material forming said shank portion.
Claim 2
Dependent Claim
268 words
A disposable, single use curette blade comprising: an elongated, unitary body member having an integrally formed shank portion, juncture portion and cutter portion with said juncture portion being disposed intermediate said shank portion and said cutter portion to connect said shank portion to said cutter portion; said shank portion extending longitudinally from said juncture portion in one longitudinal direction and in the shape of a single band of material of a substantially uniform thickness, wherein only said shank portion of said curette blade extends in said one longitudinal direction beyond said juncture portion, said shank portion including means for cooperation with a handle to selectively, releasably retain said curette blade with respect to such a handle; said cutter portion having at least one edge which forms a sharp cutting edge; said cutter portion comprising a portion of said body member extending from said juncture portion as a generally arcuate means having a pair of end portions disposed adjacent said juncture portion and said at least one edge extending arcuately intermediate said pair of end portions such that said at least one edge forms an arcuate sharp cutting edge; one of said end portions being integrally formed with said juncture portion and the other of said end portions being fixed adjacent said juncture portion by a mechanical fastener means; and wherein said cutter portion is formed of a single band of material having a thickness defined by a maximum thickness of said band of material forming said cutter portion with said defined thickness substantially equal to said substantially uniform thickness of said band of material forming said shank portion.
