<p>A dynamic sensing method and apparatus employs microelectromechanical systems (MEMS) and nanoelectromechanical (NEMS) surgical sensors for gathering and reporting surgical parameters of fluid flow and other characteristics of the surgical field. A medical device employs or affixes the surgical sensor in a fluid flow path of the fluids transferred during the surgical procedure. The surgical procedure disposes the medical device in the surgical field responsive to the fluid flow, such as in a cannula or other endoscopic instrument inserted in a surgical void defined or utilized by the surgical procedure. The reduced size of the surgical sensor allows nonintrusive placement in the surgical field, such that the sensor does not interfere with or adversely affect the flow of the fluid it is intended to measure. The reduced size is also favorable to manufacturing costs and waste for single use and disposable instruments which are discarded after usage on a patient.</p> |
