A new valving system for removal of laser plume during pelvic CO2 laser endoscopic procedures.

The large volumes of laser plume and char created during carbon dioxide laser endoscopy of the pelvis present a common problem to the gynecologic surgeon. Laser plume not only interferes with the view of the surgical field but also reduces the efficiency of emitted laser energy. A valving system has been designed and clinically tested that allows easy removal of laser-created debris while simultaneously maintaining control of the pneumoperitoneum. The system also removes these gas and liquid products without contaminating the operating room environment or hospital vacuum handling systems.
