Image processing system in orthopedic anesthesia based on optimized sedation management and regional blocking

Abstract

The invention belongs to the technical field of image processing, and discloses an image processing system in orthopedic anesthesia based on optimized sedation management and regional blocking. The image processing system comprises an ultrasonic image obtaining module, an operation state detection module, a main control module, an image processing module, a three-dimensional navigation module, a storage module and a display module. Through the image processing module, a doctor is prevented from manually identifying lesion tissue, the image identifying efficiency is improved, the doctor does not need to have a high lesion identification ability, and the labor cost is reduced. Through the three-dimensional navigation module, a virtual bone image of a surgical spot of a user and a three-dimensional image of the specific location, where a surgical instrument enters, in the user body are overlaid on a real vision of the doctor, in the surgical process, real-time navigation is conducted, thesurgical operation efficiency of the doctor is greatly improved, and a surgery is more safely, accurately and efficiently implemented.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to an image processing system based on optimized sedation management and regional block orthopedic anesthesia. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Due to the degeneration of brain function and the existence of osteoporosis and other factors, elderly users are the main group receiving orthopedic surgery, among which limb surgery is one of the main types of surgery. The main anesthesia methods currently used for this type of operation include general anesthesia and regional block, and regional block includes spinal anesthesia and peripheral nerve block. In terms of general anesthesia, the use of large doses of general anesthetic drugs, especially opioids, can have a serious impact on the user's physiological function and may have a serious impact on the user's hemodynamics during anesthes...

AI Technical Summary

Problems solved by technology

[0009] Manual lesion identification in existing orthopedic surgery has large errors and low efficiency;

[0010] At the same time, the positioning of the existing surgical guidance is complicated, requiring the user to calibrate the position of the surgical site before the operation, and each surgical instrument must also be specially made to be recognized by the positioning system; It increases the burden of surgery; and the guidance system is expensive, which cannot be afforded by general hospitals;

[0011] When ultrasonic waves propagate in a specific structure, the calculation of its dispersion characteristics (that is, the relationship between wave number and frequency) is inaccurate

[0012] In the existing modulation degree measurement profilometry, Fourier transform is used to process each frame of picture separately, and the interaction between each pixel and the filtering operation will cause the loss of object detail information, which will seriously affect the measurement accuracy; Collect N (N≧3) frames of phase-shifted fringe images at each position. Use the N-step phase-shift method to calculate the modulation degree information, which will increase the number of images collected during the scanning process, which not only affects the measurement speed, but also increases the number of images collected. , which is detrimental to its practicality
