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. <EOS>
