Abstract
A deflectable tip videoarthroscope of 5.4 mm diameter or smaller, comprising a miniaturized chip-in-tip CCD with four-way angulations mounted on the distal end of the arthroscope. The deflectable tip videoarthroscope may be provided with a replaceable distal window made of a thin material (such as polycarbonate or acrylic) or a glass (sapphire or other) with very high light transmission properties, connected to a sheathing system that is disposable or limited-reusable, which could be discarded if a shaver burr or ablation probe contacts the lens. This design protects the distal window of the videoarthroscope during use and reduces scope repair costs and system down-time. The deflectable tip videoarthroscope may additionally include a steering wheel, which allows 360 degree rotation of the instrument during arthroscopic procedures. The videoarthroscope may further include an irrigation channel or a wireless imager control system.
