Abstract: A trocar (10) is provided which permits cleaning of a medical device herein. In aspects, the trocar (10) has a seal (50) at a distal portion of the trocar (10). In use, a medical device, such as a laparoscope (200), passes through the seal (50) at the distal portion of the trocar (10). To clean a lens (210) at the end of the laparoscope (200), a vacuum is applied to the interior of the trocar (10), the laparoscope (200) is partially withdrawn so that it is proximal to the seal (50), and liquids and/or gases are introduced into the trocar (10) to clean the lens (210) while the laparoscope (200) remains within the trocar (10).

Abstract: A system for monitoring and cleaning a lens of a laparoscope interoperative includes a monitoring system having a laparoscope and software for monitoring clarity of an image provided by the laparoscope. The software being configured to provide a feedback signal when the image clarity falls below a predetermined threshold. The system further includes a cleaning system in operative connection with the monitoring system and configured to activate upon receipt of the feedback signal from the monitoring system. The cleaning system includes a source of pressurized liquid, a source of compressed air, and a source of suction. The sources of pressurized liquid and compressed air are configured to be activated simultaneously with the source of suction.

Abstract: A cleaning device (100) enables cleaning of a lens (18) of an endoscope (10) during a surgical procedure to maintain a clear image without having to remove the endoscope (10) from the patient's body. The cleaning device (100) includes a suction ring (500) that selectively encloses the lens (18) of the endoscope (10) and retains the cleaning fluid during cleaning of the lens (18).
