1. A method comprising:
providing a first elongated laparoscopic element comprising a first outer surface, a first interior tubular space, a first sensor head, and a conductor,
wherein the first elongated laparoscopic element extends in a first direction from a first proximal end to a first distal end,
the first outer surface is smooth,
the first interior tubular space extends from the first proximal end to the first distal end and has a first cross-section that is transverse to the first direction, and the first cross-section comprises a first length that extends from a first opening at the first proximal end of the first elongated laparoscopic element to a second opening at the first distal end of the first elongated laparoscopic element,
the first sensor head is positioned in the second opening of the first interior tubular space at the first distal end of the first elongated laparoscopic element, the first sensor head comprises a first structure and a second structure, the first structure is a first emitter, and the second structure is a first detector, and
the conductor, coupled to the first sensor head, extends from the first sensor head through the first interior tubular space to the first proximal end;
providing a first enclosure comprising an analog-to-digital converter circuit positioned in the first enclosure, an interface circuit coupled to the analog-to-digital converter circuit, and a battery coupled to the analog-to-digital converter and the interface circuit;
coupling the first elongated laparoscopic element and the first enclosure together to form a first oximeter device, wherein in the first oximeter device, the conductor couples the analog-to-digital converter circuit to the first sensor head through the first interior tubular space, the first enclosure comprises a second cross-section transverse to the first direction, and the second cross-section comprises a second length that is larger than the first length;
uncoupling the first elongated laparoscopic element from the first enclosure, wherein the the conductor between the first sensor head and the analog-to-digital converter circuit becomes decoupled; and
coupling a second elongated laparoscopic element to the first enclosure to form a second oximeter device, wherein the first and second elongated laparoscopic elements are different elongated laparoscopic elements.
