A novel laparoscopic pulse oximeter device. An easy, efficient and cost- effective way of detecting arterial structures.

The introduction of laparoscopy has revolutionized surgery. However, these new techniques have brought new problems into the surgical field. Due to the loss of depth and tactile sensation, time- consuming efforts must be made in order to identify normal anatomy and detect any aberrations. Even well experienced surgeons could face difficulties during demanding procedures, such as operations on inflammatory conditions. Therefore, there is still a strong need for developing additional tools to help mapping the anatomy. We designed a laparoscopic pulse oximeter device, which offers an easy, efficient and cost- effective way of using pulse oximetry in combination with a standard laparoscopic clamp in order to identify arterial structures.
