The invention discloses a spinal operation comprehensive quantitative evaluation method and device based on multi-modal ultrasonic parameters, and relates to the technical field of medical ultrasonic imaging. Aiming at the problems that the existing operation decompression assessment depends on subjective experience and has an optical blind area, the method comprises the following steps: acquiring ultrasonic data such as B ultrasonic, shear wave elasticity and ultra-micro blood flow of nerve roots before and after decompression in a liquid coupling medium, and respectively calculating change characteristic quantities of morphological, histomechanical and hemodynamic dimensions; and after normalization, substituting into a weighting model constructed by an entropy weight method, and generating a comprehensive decompression score representing physical state improvement. According to the method, subjective qualitative judgment is converted into objective quantitative evaluation, anatomical reduction and deep functional recovery are cooperatively verified, blind area hidden pressed object exploration is assisted, and the objectivity and accuracy of operation end point judgment are improved.

Disclosed is a method for assisting a user in planning a surgical procedure for spinal decompression. Medical patient image data is obtained and a critical area is identified. A planned cutting shape and / or a planned volume to be removed is obtained. User input is obtained that indicates an update of the cutting shape and / or volume. It is then determined whether the updated cutting shape and / or the updated volume to be removed intersect the critical area. A computer program, a carrier and a surgical planning system are also disclosed.

A system for assessing nerve health during spinal decompression surgery includes a stimulator, a mechanomyography sensor including an accelerometer, a display device, and a processor. The processor controls the stimulator to deliver a first electrical stimulus to a nerve prior to surgical decompression and a second electrical stimulus after surgical decompression. The processor determines a first stimulation threshold from responses detected by the sensor before decompression and a second stimulation threshold from responses detected after decompression. The processor accesses a target threshold range indicative of adequate decompression. The processor then calculates a first deviation of the first stimulation threshold from the target threshold range and a second deviation of the second stimulation threshold from the target threshold range. A value representing a change in nerve function is computed, wherein the value is based on a comparison of the first deviation to the second deviation.

A spinal decompression system and method, for safely and comfortably applying gravity-based lumbar traction to a user in a vertically suspended position, includes a spinal decompression device having an upright frame and a traction assembly suspended from the frame by a crossed strap. A forward harness support assembly is provided, to attach to the traction assembly and hold the traction assembly in a forward condition relative to the upright frame.

A method for generating a predictive model for clinical outcomes of spinal decompression surgery includes accessing a database containing historical data from a plurality of patients, where the historical data includes, for each patient: (i) patient-specific attributes, (ii) post-decompression nerve function parameters, and (iii) clinical outcomes. The processor establishes a baseline target threshold range indicative of adequate nerve decompression, the range comprising electrical current values between approximately 2 mA and approximately 3 mA. The processor determines, for each patient, a nerve function metric by comparing post-decompression nerve function parameters to the baseline target threshold range. The processor categorizes the plurality of patients into a plurality of outcome-based groups by correlating the determined nerve function metrics with the clinical outcomes. Finally, the processor generates a predictive model that associates nerve function metrics with outcome probabilities based on the outcome-based groups.
