ABSTRACT:
A control unit for a steerable probe of the type having a flexible insertion tube and a distal steering section which is articulated by displacing a pair of steering cables has a pair of pulleys which can be displaced within the housing to take up slack on the cables. A carrier plate for threaded sheath adjusters for the cable sheaths has a pair of threaded bores for the adjusters and a second pair of threaded bores that extend from the periphery of the carrier plate into the first bores. A pair of threaded set screws lock the adjusters at locking positions relative to the carrier plate. A plurality of set screws are distributed about the circumference of the distal end of the control housing. These set screws releasable engage the proximal portion of a strain relief fitting. This permits the strain relief fitting and the associated insertion tube to be rotated to a desired position relative to the housing. Then the strain relief fitting can be locked to the housing at the desired position, with the insertion tube bending access aligned with the access of the control housing.
