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.
Claims7
An apparatus for removing a needle from a needle holder, comprising:
- a grasping unit comprising arms configured to grasp the needle, each arm having at least one tapered portion;
- a receiving unit configured to receive the needle holder, at least one of said grasping unit and said receiving unit being displaceable with respect to the other of said grasping unit and said receiving unit;
- a biasing unit configured to bias at least one of said grasping unit and said receiving unit in a first direction;
- and
- separating means configured to separate the entire needle from the needle holder;
- wherein the receiving unit comprises an activating unit comprising an annular disk, which upon displacement of the displaceable one of said grasping unit and said receiving unit in a second direction opposite to the first direction, engages the tapered sections of the arms, thereby automatically causing the arms to grasp the needle;
- and
- wherein upon separation of the entire needle from the needle holder, the biasing unit automatically displaces the displaceable one of said grasping unit and said receiving unit in the first direction, thereby displacing the annular disk relative to the tapered arm portions and reducing the engagement therewith, thereby automatically releasing said separated needle.
An apparatus for removing a needle from a needle holder, comprising:
- a grasping unit comprising arms adapted to grasp the needle, each arm having at least one tapered portion;
- a receiving unit adapted to receive the needle holder, at least one of said grasping and receiving units being displaceable with respect to the other of said grasping and receiving units;
- a biasing member adapted to bias at least one of said grasping and receiving units in a first direction away from the other of said grasping and receiving units;
- a separator adapted to separate the entire needle from the needle holder;
- and
- a storage unit adapted to store the separated needle;
- wherein the receiving unit comprises an activating unit comprising an annular disk, which upon displacement of the displaceable one of said grasping unit and said receiving unit in a second direction opposite to the first direction, engages the tapered sections of the arms, thereby automatically causing the arms to grasp the needle;
- and
- wherein upon separation of the entire needle from the needle holder, the biasing unit automatically displaces the displaceable one of said grasping unit and said receiving unit in the first direction, thereby displacing the annular disk relative to the tapered arm portions and reducing the engagement therewith, thereby automatically releasing said separated needle.
