摘要： An endoscope comprising a handle and a flexible shaft connected to the handle. The flexible shaft has an active deflection section and a passive deflection section with a control wire support member therein. The endoscope also has a control wire connected to the active deflection section. A portion of the control wire is housed in the control wire support member. The control wire support member is made from a superelastic alloy material and is resiliently deflectable bending with the passive deflection section without permanent deformation or substantial fatigue over a working life of the endoscope.

摘要： A ratchet control mechanism for an endoscope having a generally elongated flexible shaft extending between a proximal control head and a distal objective assembly is shown. The ratchet control mechanism comprises an inner shaft having a first driving end and a second end which is operatively connected to a first spur gear and an outer shaft having an opening extending therethrough which encloses the inner shaft. The outer shaft has a second driving end and a second end which is operatively connected to a second spur gear. The outer shaft rotatably supports the inner shaft, the first spur gear on the second end of the inner shaft being in a spaced opposed relationship from the second spur gear on the second end of said outer shaft. The ratchet control mechanism further includes a ratchet mechanism having a rotatable ratchet member having an outer cam surface and positioned substantially perpendicular to and spaced from the first spur gear and the second spur gear. A pair of resilient actuation members are positioned in the space between the first and second spur gears and the outer cam surface forming a ratchet engagement therebetween such that rotation of at least one of the inner shaft and the outer shaft may occur under ratchet control to inhibit reversal of motion. The ratchet engagement may be variable ranging from no ratchet engagement, light ratchet engagement and heavy ratchet engagement.

摘要： A cable compensating mechanism for an endoscope is shown. The endoscope has a generally elongated flexible shaft extending between a control head at a proximal end thereof and an objective assembly at the distal end thereof. The cable compensating mechanism includes an operative cable and sheath assembly which is operatively connected to the objective assembly and to the control head for deflecting the objective assembly in a selected direction.A control mechanism is operatively connected to the operating cable and sheath assembly and is adapted to control the magnitude of tensile force developed in the operating cable in the event that deflection of the objective assembly is restrained. The control mechanism has a guide block and carriage member moveable therein. The moveable carriage member moves the operating cable and sheath assembly within the sheath. The guide block includes a first resilient member which is capable of being compressed between the guide block and the carriage member when the tensile force on the operating cable reaches a first predetermined value. The guide member includes a second resilient member to restrain movement of the carriage member when the tensile force is below said predetermined value and when said tensile force reaches at least the predetermined value, the second resilient member releases the carriage member which moves the operating cable and sheath assembly within the guide block.
