Abstract

An apparatus for removing a needle from a needle holder, including a grasping unit for selectively grasping the needle; a receiving unit for receiving the needle holder, displaceably disposed relative to the grasping unit; a biasing member biasing the receiving unit in a first direction; and separating means for separating the entire needle from the needle holder. Preferably, the needle is heated to melt, soften, or otherwise weaken a material and/or adhesive connecting the needle with the needle holder. Preferably the heating is electrical heating, including completing an electrical circuit through the needle and passing current through the needle, and/or passing current through a heating element.

First claim

What is claimed is:

1. A method of separating a needle from a needle holder, comprising:
receiving the needle holder in a receiving unit biased in a first direction;
displacing the receiving unit relative to a grasping unit in a second direction opposite to the first direction, thereby automatically causing the grasping unit to grasp the needle and activating a separator for separating the needle from the needle holder; and
maintaining the grasp of the needle until the separator separates the entire needle from the needle holder;
wherein activating the separator comprises completing an electrical circuit through the needle.

2. A method of separating a needle adhered to and/or molded in a needle holder, comprising:
receiving the needle holder in a receiving unit;
grasping the needle with a grasping unit;
with a separator, completing an electrical circuit through the needle and passing current through the needle to melt, soften, or otherwise weaken a material and/or adhesive connecting the needle with the needle holder, and separating the entire needle from the needle holder.

3. The method according to claim 2 , wherein the current passes through a portion of the needle where the needle is connected to the needle holder.

4. The method according to claim 2 , wherein the current passes through a portion of the needle other than a portion of the needle where the needle is connected to the needle holder, and heat is conducted to the portion of the needle where the needle is connected to the needle holder.

5. The method according to claim 2 , further comprising disposing of the separated needle.

6. The method according to claim 2 , further comprising disposing of or recycling the needle holder.
