Abstract
A method for intraoperative guidance during a surgical procedure involving a nerve includes receiving real-time image data from an intraoperative imaging modality, the real-time image data depicting anatomical structures within an intracorporeal treatment area including the nerve; determining at least one nerve function parameter indicative of nerve health; and controlling a display device to concurrently present a visual output comprising both a visual representation derived from the real-time image data and a visual indication of the determined at least one nerve function parameter. The concurrently presented visual output facilitates assessment of the nerve relative to the anatomical structures during the surgical procedure.

A method for intraoperative guidance during a surgical procedure involving a nerve, the method performed by a system comprising a processor, the method comprising:
- receiving, by the processor, real-time image data from an intraoperative imaging modality, the real-time image data depicting anatomical structures within an intracorporeal treatment area including the nerve;
- determining, by the processor based on signals received from a sensor configured to detect muscle responses evoked by electrical stimuli applied near the nerve, a value of at least one nerve function parameter indicative of nerve health;
- determining, by the processor, a statistical risk of complications based on the value of the at least one nerve function parameter;
- controlling, by the processor, a display device to concurrently present a visual output comprising both a visual representation derived from the real-time image data and a visual indication of the determined at least one nerve function parameter, wherein the visual indication of the determined at least one nerve function parameter includes at least one of:
- a numerical or graphical representation of the value of the nerve function parameter;
- a numerical or graphical representation of a difference between the value of the nerve function parameter and a target range for the value of the nerve function parameter;
- or
- a color-coded representation of the value of the nerve function parameter;
- and
- controlling, by the processor, the display device to present a visual representation of the statistical risk of complications alongside the visual indication of the determined at least one nerve function parameter.
A system for providing integrated intraoperative guidance during a surgical procedure involving a nerve, the system comprising:
- an imaging interface configured to receive real-time image data from an intraoperative imaging modality, the real-time image data depicting anatomical structures within an intracorporeal treatment area including the nerve;
- a sensor configured to detect muscle responses evoked by electrical stimuli applied near the nerve and generate sensor signals indicative thereof;
- a display device;
- and
- a processor communicatively coupled to the imaging interface, the sensor, and the display device, the processor configured to:
- receive the real-time image data via the imaging interface;
- determine, based on the sensor signals, a value of at least one nerve function parameter indicative of nerve health;
- determine a statistical risk of complications based on the value of the at least one nerve function parameter;
- control the display device to concurrently present a visual output comprising both a visual representation derived from the real-time image data and a visual indication of the determined at least one nerve function parameter, wherein the visual indication of the determined at least one nerve function parameter includes at least one of:
- a numerical or graphical representation of the value of the nerve function parameter;
- a numerical or graphical representation of a difference between the value of the nerve function parameter and a target range for the value of the nerve function parameter;
- or
- a color-coded representation of the value of the nerve function parameter;
- and
- control the display device to present a visual representation of the statistical risk of complications alongside the visual indication of the determined at least one nerve function parameter.
