Combined control handle and viewing screen for an endoscope

A control handle and viewing screen assembly combines video monitor and remote steering control for a borescope steering section. A joystick or similar device controls the steering section when an inspection mode is employed. In a second or freeze-frame mode the joystick is used to move a cursor on the screen or to carry out a computation function. Steering servo motors can be positioned distally for balance.

Control and display section for borescope or endoscope

A disposable seal is provided for a luer lock end fitting, e.g. for a biopsy channel of an endoscope. The fitting has a tubular luer lock device and a retaining ring surrounding the tubular device. The seal is unitarily molded of a soft elastomer and has a double seal arrangement formed of an apertured end wall and a one-way-opening slitted plate or web behind the end wall. A distal end of the seal fits over the tubular luer lock device. This distal end has a radial cuff that seals against a flat transverse surface of the retaining ring and a frustoconic tapered protruding member which fits against a similar inner surface of the retaining ring to ensure that the cuff sealably engages the retaining ring under overpressure conditions.
