AI Technical Summary

Technical Problem

In existing technologies, the anatomical morphological data and functional electrical stimulation data of ultrasound equipment and electrical stimulators are inherently heterogeneous, making it impossible to achieve real-time and accurate mapping. This results in poor positioning deviation and visualization of safety boundaries, a lack of adaptive control capabilities, and an inability to achieve active safety protection.

Method used

By constructing a multimodal spatiotemporal synchronous coordinate system, pixel-level spatiotemporal registration of ultrasound anatomical morphological data and functional response vectors of electrical stimulation is achieved. The functional effective distance is calculated using a neural excitability model, and spatial constraint envelopes of virtual safety blocking zones and risk warning zones are generated. These are then superimposed on ultrasound images in real time using an image synthesis algorithm. The relative position of the needle tip trajectory and the virtual envelope is monitored in real time, and the electrical stimulation waveform parameters are automatically adjusted.

Benefits of technology

It achieves strict synchronization and deep visualization fusion of anatomical structure imaging and neurofunctional feedback in the spatiotemporal dimensions, realizing a leap from qualitative experience judgment to quantitative intelligent navigation, and achieving active safety protection during the puncture process.

Abstract

The invention discloses an ultrasonic and electrical stimulation dual-positioning regional anesthesia puncture guiding method and device. The method comprises the following steps: constructing a multi-modal space-time synchronous coordinate system, acquiring sound wave echoes of an ultrasonic transducer array and electrophysiological impedance signals of a conductive tip of a puncture needle, mapping the sound wave echoes and the electrophysiological impedance signals into a data matrix and a response vector, and executing pixel-level space-time registration; inversely calculating a functional effective distance by using a neural excitability model, and generating a virtual space constraint envelope containing a safety retardation and risk early warning area; projecting the envelope to an ultrasonic imaging plane, and overlapping and displaying the visual boundary and the dynamic warning map to generate a fused guide image; the relative position of the needle point track and the envelope is monitored in real time, and when an early warning area is intruded or the distance is out of tolerance, electrical stimulation waveform parameters are automatically adjusted, and the warning state is synchronously updated. The regional anesthesia puncture guiding method solves the technical problems that according to a regional anesthesia puncture guiding method in the prior art, multi-modal data space-time registration is lacked, and functional safety boundary visualization is poor.
