Couplers designed to connect a laser delivery system (typically the articulating arm of a carbon dioxide laser) and a laparoscope, aligning the aiming beam and the treatment beam on the tissue. These couplers typically consist of the main coupling device (lens housing), set of lenses, a laparoscope adapter, and a sleeve. The main coupling device is attached to the laser delivery system (e.g., articulating arm) at the proximal end; the laparoscope adapter at the distal end; and then the sleeve is placed inside the working channel of the laparoscope to provide a path for the laser beam to the tissue. Some couplers include a joystick for adjusting the direction of the laser beam. Most couplers can also be used with auxiliary (double-puncture) laparoscopes. Laser/laparoscope couplers are intended for laparoscopic procedures (e.g., gynecologic) using lasers with a wavelength that is not appropriate for fiberoptic cable transmission.
