An apparatus for entirely removing a medical sharp from a holder to which it is connected, comprising: a body; a heating unit disposed in the body; a receiving unit configured to receive the holder; a collet movably disposed within the body and configured to receive the medical sharp; a first biasing member disposed within the body; characterized in that the apparatus further comprising: a door member movably disposed on the body and configured to contact the holder, displacement of the door member by a predetermined distance enables operation of the heating unit by actuating a sensor or completing a portion of an electrical circuit; a user interface coupled to the collet and movable in a first direction to displace the collet away from the receiving unit, actuate the first biasing member to increase a bias on the collet toward the receiving unit, and actuate the heating unit; and a second biasing member disposed between the user interface and the collet, configured to bias the collet away from the receiving unit; wherein displacing the user interface in the first direction by a predetermined distance causes the collet to grip the needle, actuates the first biasing member to increase the bias of the collet toward the receiving unit, and actuates the heating unit by actuating a sensor or completing the electrical circuit. a body; a heating unit disposed in the body; a receiving unit configured to receive the holder; a collet movably disposed within the body and configured to receive the medical sharp; a first biasing member disposed within the body; characterized in that the apparatus further comprising: a door member movably disposed on the body and configured to contact the holder, displacement of the door member by a predetermined distance enables operation of the heating unit by actuating a sensor or completing a portion of an electrical circuit; a user interface coupled to the collet and movable in a first direction to displace the collet away from the receiving unit, actuate the first biasing member to increase a bias on the collet toward the receiving unit, and actuate the heating unit; and a second biasing member disposed between the user interface and the collet, configured to bias the collet away from the receiving unit; wherein displacing the user interface in the first direction by a predetermined distance causes the collet to grip the needle, actuates the first biasing member to increase the bias of the collet toward the receiving unit, and actuates the heating unit by actuating a sensor or completing the electrical circuit. a door member movably disposed on the body and configured to contact the holder, displacement of the door member by a predetermined distance enables operation of the heating unit by actuating a sensor or completing a portion of an electrical circuit; a user interface coupled to the collet and movable in a first direction to displace the collet away from the receiving unit, actuate the first biasing member to increase a bias on the collet toward the receiving unit, and actuate the heating unit; and a second biasing member disposed between the user interface and the collet, configured to bias the collet away from the receiving unit; wherein displacing the user interface in the first direction by a predetermined distance causes the collet to grip the needle, actuates the first biasing member to increase the bias of the collet toward the receiving unit, and actuates the heating unit by actuating a sensor or completing the electrical circuit.
