Spine image generating system based on ultrasonic rubbing technology and spine surgical navigation positioning system

Abstract

A spine image generating system based on an ultrasonic rubbing technology comprises a collecting unit and a processing unit. Ultrasonic rubbings are generated by the system based on ultrasonic imageswith two-dimensional spine surface structure characteristic outlines, and matched with a digital medical image outline, and thus a personalized spine surface topographic map which is consistent with an intraoperative position of a patient and updated in real time is obtained. A spine surgical navigation positioning system based on the spine image generating system comprises a navigation module andthe spine image generating system based on the ultrasonic rubbing technology. The spine surgical navigation positioning system can obtain the spine surface topographic map which is consistent with the intraoperative position of the patient and updated in real time, and can conduct real-time intraoperative navigation based on the spine surface topographic map. The spine image generating system based on the ultrasonic rubbing technology and the spine surgical navigation positioning system can greatly reduce the difficulty of a spinal operation, can achieve the operation auxiliary purposes of precise and nonradiative guided puncture, real-time navigation and being simple, convenient and reliable, and are particularly beneficial for application and popularization of a spinal minimally invasive surgery technology which is represented by a spine endoscopy to primary health care institutions.

Description

Technical field: [0001] The invention relates to the medical field, in particular to a spinal image generation system, a spinal image generation method, a spinal surgery navigation and positioning system, and a spinal surgery navigation and positioning method. Background technique: [0002] At present, the incidence and number of patients with spinal degeneration-related diseases are increasing day by day, seriously affecting people's health and working ability. Spine surgery is the main method for treating spinal diseases such as disc herniation and tumors. Among them, the minimally invasive surgery technology represented by spinal endoscopy is becoming more and more mature due to the upgrading of surgical instruments and equipment promoted by scientific and technological progress. The advantage of quick recovery has been recognized and accepted by more and more fields. However, these minimally invasive techniques have high requirements on the positioning accuracy of lesio...

Problems solved by technology

[0022] In view of the existing deficiencies, the technical problem to be solved by the present invention is to provide a spine image generation system and method based on ultrasound rubbing technology, creatively obtain the two-dimensional spine surface corresponding to the real-time intraoperative body position under the patient's surgical condition Structural ultrasonic images are processed to form ultrasonic rubbings. The ultrasonic rubbings are personalized three-dimensional ultrasonic bone images that carry the patient’s spatial positioning information and are dynamically updated in real time as the patient’s position changes. The ultrasonic rubbings are combined with digital medical images. After contour matching, a real-time updated personalized spine surface topographic map that is consistent with the patient's intraoperative position is further obtained, thus completely solving the problem that the existing technology cannot obtain the relevant parts (including necessary parts and specific parts) required for spinal surgery. The problem of spatial position information, as well as the problems of real-time lag and real-time dynamic display in the existing technology, realize the precise treatment operation of spinal surgery guided by navigation technology
