Claim 16:
17. A device comprising:
a first portion comprising an elongated laparoscopic element, wherein the elongated laparoscopic element extends in a first direction and comprises a proximal end and a distal end, opposite the proximal end, a smooth outer surface, and an interior tubular space, and
the interior tubular space comprises a first cross-section transverse to the first direction, and the first cross-section comprises a first length,
a sensor head, coupled to the distal end of the elongated laparoscopic element, wherein the interior tubular space of the elongated laparoscopic element extends from a first opening at the proximal end of the elongated laparoscopic element to the sensor head,
the sensor head comprises a first structure and a second structure, the first structure is an emitter, and the second structure is a detector,
a printed circuit board comprising a current-to-voltage converter circuit coupled to the detector, wherein the printed circuit board comprises a first surface on which components of the current-to-voltage converter circuit are formed and a second surface, and a plane of the first surface and a plane of the second surface are parallel with the first direction, and
an electrical conductor, coupled to the current-to-voltage converter circuit;
a second portion, coupled to the first portion at the proximal end of the elongated laparoscopic element, wherein the second portion comprises a first enclosure having 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,
the first enclosure comprises
an analog-to-digital converter circuit, coupled to the second structure of the sensor head, wherein the electrical conductor extends from a first end of the printed circuit board through the interior tubular space of the elongated laparoscopic element to couple to the analog-to-digital converter circuit,
an interface circuit, coupled to the analog-to-digital converter circuit, wherein the interface circuit comprises a first wired transceiver circuit, and
a battery, coupled to the analog-to-digital converter and interface circuits; and
a third portion comprising a second enclosure, separate from the first enclosure, wherein the second enclosure comprises
a second wired transceiver circuit, which is coupled to the first wired transceiver circuit via a cable,
a processing circuit, coupled through the second wired transceiver circuit and the cable to the analog-to-digital converter circuit, and
a display, coupled to the processing circuit and a power source separate from the battery of the first enclosure.
