Abstract
An instrument for guiding a laser light transmitting fiber in intra-abdominal endoscopic work, comprises a shaft to the distal end of which is pivoted a fiber guide for deflecting the distal end of a fiber emerging from the distal end of the shaft. The shaft contains a fiber guide drive tube through which the fiber extends and which is articulated to the fiber guide by means of a link. A lever is provided for shifting the drive tube axially in the shaft to deflect the fiber guide and thus the distal end of the fiber, and a fiber feed device has a fiber feed member mounted for displacement axially of the shaft for advancing and retracting the fiber.
