Abstract
A surgical laser endoscopic focusing guide for a laser fiber optical link comprises a disposable unit (14) which is connected to the end of an optical fiber link (10). The unit consists of an endoscopic tube (16), the front end of which contains a mirror lens (22) for directing a laser beam emitted from the unit onto the operation area. The lens (22) bends the beam in a lateral direction onto a tissue to be treated. In an embodiment for laser angioplasty, the unit has a firm and reliable attachment directly to a buffer layer (80) of the optical fiber link. This ensures flexibility required for operaton in narrow and curved vessels and provides firm attachment of the mirror lens to the tube.
