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 16):
An endoscope comprising a braking system for an articulation unit of the endoscope, said braking system 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 that is coupled with a first cable pair that is coupled with the articulation unit of the endoscope, at least a portion of the first shaft in proximity of the first operating knob having 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 that is coupled with a second cable pair that is coupled with the articulation unit of the endoscope, the first shaft is positioned within the second shaft; a right/left movement controller unit comprising:\n a brake knob rotatable about its center axis; \n a first stationary sleeve arranged between the first and the second shafts; \n a first spring being supported by the first shaft in proximity to the first end; \n a pin having a tapered distal end and extending into the space of the first shaft in a first pin position; and \n three brake bodies extending outwardly from said pin and positioned equidistant from one another about a periphery of said pin; \n wherein the pin is movable from the first pin position into a second pin position further into the space of the first shaft by rotational motion of said brake knob in a first brake knob rotational direction and compression of said first spring, wherein each of said brake bodies becomes pressed against said first stationary sleeve when said pin is in said second pin position, thereby locking said first shaft and braking the articulation unit in a first predetermined direction; further wherein said pin is movable from said second pin position into said first pin position by rotational motion of said brake knob in a second brake knob rotational direction opposite said first brake knob rotational direction, allowing the compressive force of said first spring to push said pin into said first pin position.
