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 1):
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 and a first cable pair that are coupled with the articulation unit of the endoscope, wherein at least a portion of the first shaft in proximity to the first operating knob includes 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 and a second cable pair that are coupled with the articulation unit of the endoscope, wherein the first shaft is positioned within the second shaft; a brake knob rotatable about its center axis; a stationary sleeve arranged between the first and the second shafts; a spring supported by the first shaft in proximity to the first end of the first shaft; a pin extending into the space of the first shaft and coupled to said brake knob by the spring, wherein said pin has a first position and a second position; and at least one brake body extending outwardly from said pin, wherein said at least one brake body does not press against the stationary sleeve when the pin is in the first position; wherein the pin is movable from the first position into the second position by rotational motion of said brake knob in a first rotational direction and compression of said spring, wherein said at least one brake body becomes pressed against said stationary sleeve when said pin is in said second position, thereby locking said first shaft and braking the articulation unit in a predetermined direction, and wherein said pin is movable from said second position into said first position by rotational motion of said brake knob in a second rotational direction opposite said first rotational direction, thereby allowing the compressive force of said spring to push said pin into said first position.
