Abstract: A method for housing a reusable portion of an oximeter device in a sheath includes providing the oximeter device as a probe unit and a laparoscopic tube separated from each other. The probe unit is handled by a first operator in a nonsterile environment and the laparoscopic tube is handled by a second operator in a sterile environment. The first operator connects the probe unit and the laparoscopic tube to form the oximeter device. The sheath is coupled to the laparoscopic tube in a folded configuration and is pulled by the second operator to enclose the probe unit. The oximeter device is in the sterile environment when the probe unit is in the sheath. The oximeter device is for use in an intraoperative procedure and the sheath inhibits the probe unit from contacting contaminants so that the probe unit is reusable, whereas the laparoscopic tube can be disposed of.

Abstract: A laparoscopic medical device includes an oximeter sensor at its tip, which allows for making oxygen saturation measurements laparoscopically. The laparoscopic medical device includes a probe unit and a laparoscopic tube that detachably connects with the probe unit so that the laparoscopic tube can be replaced for different patient surgeries and the probe unit can be reused. The probe unit includes a number of optical fibers and the detachable laparoscopic tube includes a number of optical fibers where tips of the fibers of the probe unit and laparoscopic tube connect end to end. Cores of the transmitting optical fibers have smaller numerical apertures and smaller diameters than cores of the receiving optical fibers to facilitate a high percentage of light transmission even when the optical fibers are misaligned at their contacting ends.
