Medical device interface system

An interface device for securing an instrument to a docking station having a casing having at least one signal port and a mounting rail mounted within a recessed portion of the casing, said interface device comprising:

• a back panel forming part of an instrument housing for housing the instrument;
• a first portion protruding rearward from the back panel;
• a first recess carried by the first protruding portion, the first recess dimensioned to receive the mounting rail;
• a rail cam rotatably mounted within the first protruding portion and aligned with the first recess to receive and retain the mounting rail;
• and
• at least one first protruding portion signal port carried by the first protruding portion;
• wherein the first protruding portion is dimensioned to fit within the recessed portion of the casing such that the rail cam is positioned to receive the mounting rail and the at least one first protruding portion signal port is aligned, in a complementary fashion, with the at least one casing signal port.

A rail cam forming part of an instrument housing, said rail cam for securing the instrument housing to a mounting rail mounted to a surface, the mounting rail having a height and depth, said rail cam comprising:

• a cam base having a surface, the cam base mounted for pivotal movement relative the remainder of the instrument housing;
• two opposing arms near a periphery of the cam base, the arms extending substantially perpendicular relative the surface of the cam base, each arm having an arm base defining a lock surface, the arms positioned on the cam base such that the distance between the two lock surfaces is substantially equal to the height of the mounting rail;
• and
• a guiding portion at the top of each arm base for contacting the mounting rail during insertion of the rail cam onto the mounting rail and transferring the force of contact with the mounting rail to the cam base to therein induce rotation of the rail cam from a closed/lock position to a opened/receive position during which the rail cam receives the mounting rail and subsequently removing the force from the cam base to allow rotation of the rail cam from the open/receive position to the closed/lock position during which the rail cam retains the mounting rail.

A device interface for securing an instrument to a docking station having a casing having a mounting rail mounted within an alignment portion of the casing, said interface device comprising:

• an alignment member forming part of an instrument housing for housing the instrument;
• and
• a rail cam rotatably mounted to the instrument housing and configured to receive and retain the mounting rail;
• wherein the alignment member interfaces with the alignment portion such that the rail cam is positioned to receive the mounting rail.
