First claim

1 - 33 . (canceled)

34 : A device for imparting a force, comprising:
a rod having a shaft including a proximal end, a distal end spaced apart from said distal end, and a longitudinal axis extending from said proximal end to said distal end through said rod; a motor producing a periodic motion; a driver system, coupled to said proximal and to said motor, producing a driven rod motion for said distal end from said period motion; an attachment system coupled to said distal end, said attachment system configured to engage an attachment structure; and a set attachments, each particular attachment from said set of attachments including said attachment structure; wherein said driven rod motion includes a selectable mode chosen from a mode group including a bidirectionally driven mode having a first driven direction and a second driven direction.

35 : The device of claim 34 wherein said mode group further includes a first unidirectional mode and further comprising a mode selector to select a particular one mode from said bidirectionally driven mode and said first unidirectional mode.

36 : The device of claim 34 wherein said bidirectionally driven mode includes a bidirectional longitudinal motion mode.

37 : The device of claim 36 wherein said mode group further includes a first unidirectional longitudinal mode and further comprising a mode selector to select a particular one mode from said bidirectional longitudinal motion mode and said first unidirectional longitudinal mode.

38 : The device of claim 34 wherein said bidirectionally driven mode includes a bidirectional rotational motion mode.

39 : The device of claim 38 wherein said mode group further includes a first unidirectional rotational mode and further comprising a mode selector to select a particular one mode from said bidirectional rotational mode and said first unidirectional rotational mode.

40 : The device of claim 34 wherein said set of attachments includes a bone reamer.

41 : The device of claim 41 wherein said set of attachments includes a set of reamers including a range of varying sizes and wherein said range of varying sizes include ½ millimeter variations.

42 : The device of claim 38 wherein said set of attachments includes a bone reamer.

43 : The device of claim 42 wherein said set of attachments includes a set of reamers including a range of varying sizes and wherein said range of varying sizes include ½ millimeter variations.

44 : The device of claim 34 wherein said set of attachments includes an acetabular broach.

45 : The device of claim 36 wherein said set of attachments includes an acetabular broach.

46 : The device of claim 34 wherein said bidirectionally driven mode operates at an ultrasonic frequency.

47 : The device of claim 42 wherein said bidirectionally driven mode operates at an ultrasonic frequency.

48 : The device of claim 44 wherein said bidirectionally driven mode operates at an ultrasonic frequency.

49 : A method for imparting a force to a tool, comprising:
a) producing a periodic motion; b) producing a driven rod motion for a distal end of a rod from said period motion; and c) engaging said distal end with a particular one attachment from a set of attachments, said particular one attachment including the tool; wherein said driven rod motion includes a selectable mode chosen from a mode group including a bidirectionally driven mode having a first driven direction and a second driven direction.

50 : The method of claim 49 wherein said mode group further includes a first unidirectional mode and further comprising d) selecting a particular one mode from said bidirectionally driven mode and said first unidirectional mode.

51 : The method of claim 49 wherein said bidirectionally driven mode includes a bidirectional longitudinal motion mode.

52 : The method of claim 51 wherein said mode group further includes a first unidirectional longitudinal mode and further comprising d) selecting a particular one mode from said bidirectional longitudinal motion mode and said first unidirectional longitudinal mode.

53 : The method of claim 49 wherein said bidirectionally driven mode includes a bidirectional rotational motion mode.

54 : The method of claim 53 wherein said mode group further includes a first unidirectional rotational mode and further comprising d) selecting a particular one mode from said bidirectional rotational mode and said first unidirectional rotational mode.

55 : The method of claim 49 wherein said particular one attachment includes a bone reamer.

56 : The method of claim 55 wherein said set of attachments includes a set of bone reamers including a range of varying sizes and wherein said range of varying sizes include ½ millimeter variations.

57 : The method of claim 53 wherein said particular one attachments includes a bone reamer.

58 : The device of claim 57 wherein said set of attachments includes a set of reamers including a range of varying sizes and wherein said range of varying sizes include ½ millimeter variations.

59 : The method of claim 49 wherein said particular one attachment includes an acetabular broach.
