Tissue oximeter intraoperative sensor
First Claim
Patent Images
1. An oximeter device comprising:
- a sensor head comprising a probe face that faces a tissue to be measured;
first, second, and third sensor structures formed on the probe face, wherein a first distance is between the first and second sensor structures, and a second distance is between the first and third sensor structures, and the first distance is different from the second distance;
a handle; and
an elastic member comprising a spring constant, coupled between the sensor head and handle.

Abstract
An oximeter probe includes sensor head with a probe face having one or more sensor structures to make measurements, a handle, and an elastic member connected between the handle and the base. A user can hold the handle while measurements are made and the elastic member permits the handle to flex relative to the sensor head with one or more sensor structures.
