Oximeter System with Durable Unit and Replaceable Sheath

A system comprising:

• an oximeter device comprising:
• a first device portion comprising:
• a sheath, comprising an upper portion and a lower portion, wherein the lower portion is coupled to the upper portion by a hinge, and the upper and lower portions can rotate relative to each other by the hinge;
• the lower portion comprises a first opening at a distal end and a second opening at a proximal end,
• the upper portion comprises a third opening at a distal end, and by rotation of the hinge, the third opening can mate with the second opening to form a sealed enclosed space within the upper and lower portions;
• a laparoscopic tube, coupled to the first opening at a proximal end of the laparoscopic tube;
• and
• a sensor head, coupled to a distal end of the laparoscopic tube;
• and
• a second device portion comprising:
• an enclosure, comprising an interior space;
• an electrical connector, formed at a distal end of the enclosure;
• a printed circuit board comprising electrical circuitry, wherein the printed circuit board is enclosed within the interior space and coupled to the electrical connector;
• a battery compartment, formed in the enclosure, wherein the battery compartment is covered by a battery cover that forms an exterior surface of the enclosure;
• and
• a display, coupled to the enclosure and the printed circuit board,
• wherein the enclosure of the second device portion fits into the upper portion of the sheath of the first device portion, and when the third opening mates with the second opening, the enclosure of the second device portion is within the sealed enclosed space within the upper and lower portions of the first device portion;
• a network;
• a robot arm, coupled to the oximeter and the network;
• an operating console, located in a different location than the robot arm, wherein the operating console is coupled to the robot via the network;
• and
• a display device, wirelessly connected to the oximeter device and separate from the operating console, wherein the display device displays oxygen saturation values measured by the oximeter device.
