Abstract:
A device for converting continuous rotation of a shaft into reciprocal rotational motion of a beveled needle comprising:a) a first shaft having a first end, a second end and a length defining a first shaft axis therebetween, wherein said first end is adapted to connect to a motor for imparting a continuous rotation on said first shaft about said first shaft axis; b) a first disk rigidly attached to said second end of said first shaft, said first disk comprising an attachment pin formed on a side thereof; c) a second shaft having a first end, a second end and a length defining a second shaft axis therebetween, wherein said second end of said second shaft is connected to a beveled needle; d) a second disk rigidly attached to said first end of said second shaft, said second disk comprising an attachment pin formed on a side thereof; e) a connector arm having a first end and a second end, wherein said first end of said connector arm being operatively connected to said attachment pin of said first disk and said second end of said connector arm being operatively connected to said attachment pin of said second disk; and f) translating means for providing said reciprocal rotational motion, in communication with said second disk, for converting said continuous rotational motion of said first shaft about said first shaft axis into said reciprocal rotational motion of said second shaft about said second shaft axis.
