DYNAMIC SURGICAL FLUID SENSING
First Claim
1. In a medical device environment, a method of measuring surgical parameters comprising:
- identifying a surgical void responsive to receiving a fluid flow for a therapeutic procedure, the surgical void in communication with at least one endoscopic instrument for performing the therapeutic procedure;
encoding an integrated micromechanical device with power, sensing, and transmission capabilities, the integrated micromechanical device adapted for nonintrusive attachment to the endoscopic instrument;
introducing the integrated micromechanical device into the surgical void via the endoscopic instrument;
directing a fluid flow into the surgical void for maintaining a positive pressure and evacuating surgical material resulting from the therapeutic procedure;
disposing the integrated micromechanical device in a fluid path of a therapeutic procedure via the endoscopic instrument;
activating the integrated micromechanical device for measuring surgical parameters including at least one of pressure, flow and temperature of the fluid flow within the surgical void; and
receiving the measured surgical parameters via a wireless transmission from the integrated micromechanical device.

Abstract
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.
