Abstract:
A control unit that includes a braking system for fixing the position of an endoscope tip is provided. The control system includes an up-down control knob and a right-left control knob. The brakes are engaged by rotating the control knob itself counter-clockwise from a free wheeling position. After the brakes have been engaged, a sufficient amount of force applied to the control knobs will move the endoscope tip slightly in the corresponding direction, allowing for fine tuning of tip position after braking.

Claim (Index 10):
A control unit providing a braking system for an articulation unit of endoscope, said control unit comprising:\n a first shaft having a first end and a second end, the first end being coupled with a first operating knob, the second end being coupled with a first cable drum, a first cable pair, and the articulation unit of the endoscope, at least a portion of the first shaft in proximity of the first operating knob including a space; a second hollow shaft having a first end and a second end, the first end being coupled with a second operating knob, the second end being coupled with a second cable drum, a second cable pair, and the articulation unit of the endoscope, the first shaft is positioned within the second shaft; a brake disc having a central opening through which said second shaft extends, said brake disc being in physical contact with the second shaft; a stationary sleeve surrounding at least a portion of the second shaft; a brake base positioned below said brake disc, having a central opening through which said second shaft extends and comprising a first control edge; a brake lid positioned above said brake base and said brake disc, coupled to said brake base, having a central opening through which said second shaft extends and comprising a second control edge; a spring positioned between said brake base and said brake lid; a brake bushing positioned between said brake base and said brake lid and below said brake disc, having a central opening through which said second shaft extends and being movable vertically between first and second brake bushing positions; and a brake handle attached to said brake base for rotating said brake base and brake lid; wherein said brake bushing is movable from said first position to said second position by rotating said brake handle in a first rotational direction, causing said brake bushing to move upward and compress said brake disc against said brake lid, thereby locking the second shaft and braking the articulation unit in a predetermined direction, further wherein said brake bushing is movable from said second position into said first position by rotational motion of said brake handle in a second rotational direction opposite said first rotational direction, allowing the compressive force of said spring to push said brake bushing into said first position.
