Abstract
The proximal connector includes a stainless steel cone-shaped ferrule enclosing a proximal end of the optic fiber element. The ferrule is inserted within a matching aperture of a receiving block which is also made of stainless steel. The matching shapes of the ferrule and the aperture of the receiving block ensure effective heat transference from the ferrule into the receiving block. Both ferrule and the aperture are axially symmetric such that any rotation of the proximal connector while inserted into the receiving block does not change the location of the entrance aperture of the optic fiber element. The proximal connector also includes a case having an indented ring. A ball plunger biasing mechanism is mounted within the aperture of the receiving block and is positioned for engaging with the indented ring only while the proximal connector is fully and securely inserted within the aperture. The plunger prevents accidental removal of the proximal connector while also providing a biasing force for ensuring solid contact between the cone-shaped ferule and the corresponding portions of the receiving block to further facilitate the heat conduction.
