A system and method for intelligent positioning of spinal cord body surface puncture entry points based on multi-modal medical fusion images

Abstract

The invention discloses an intelligent positioning system and method for approach points of spine and spinal cord body surface puncture based on multi-mode medical fusion images, belonging to the medical field. The present invention uses ultrasound technology for real-time spine image acquisition; obtains two-dimensional ultrasound images and spatial position information corresponding to two-dimensional ultrasound images, and reconstructs them to obtain three-dimensional ultrasound reconstruction images; inputs spine multi-mode medical imaging acquired in a non-ultrasonic manner to the system. image; re-fused to obtain a fused image. The fused images can be used for puncture training or to assist surgery. The invention relies on the image processing technology to improve the technical shortcomings of the traditional ultrasonic imaging technology for imaging the bony structure of the spine; it improves the shortcomings of large puncture damage and radiation damage, cumbersome and time-consuming steps, and will be greatly improved in clinical practice and simulation training. Advancing spinal cord surgery today.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an intelligent positioning system and method for spinal cord body surface puncture entry points based on multi-mode medical fusion images. Background technique [0002] Spinal cord-related diseases include spinal cord tumors, trauma, and degenerative diseases. In recent years, the incidence of spinal cord-related diseases has been increasing, seriously affecting people's health and working ability. In my country, the diagnosis and treatment of spinal cord-related diseases are mainly undertaken by spine surgeons and neurosurgeons, and surgical treatment is one of the main treatment methods. At present, spinal cord surgery is mainly divided into two categories: open surgery and minimally invasive surgery. With the development of medical equipment and navigation technology in recent years, minimally invasive surgery has gradually become the mainstream due to its advantages of less damage, le...

Problems solved by technology

At present, ultrasound-guided spinal nerve block and epidural anesthesia puncture are widely used, and ultrasound is also combined with other medical images such as CT and MRI to form two-dimensional fusion images and be used to assist navigation and positioning. Related equipment and image processing software The use of ultrasonic imaging can give full play to the advantages of real-time, portable, and radiation-free ultrasound images. However, ultrasonic imaging is more suitable for soft tissue structures, while for bone structures, due to the existence of sound wave attenuation, distortion and reflection, ultrasonic bone images are blurred and surface burrs are difficult. Clear imaging and precise positioning lead to limited universality and reliability of existing technologies in practical applications

[0006] In addition, in view of the high technical threshold and long learning curve of minimally invasive operation techniques, young operators do not yet have sufficient knowledge and experience. Mentoring at the beginning of the job is particularly difficult

Existing training methods, systems and equipment can better simulate the overall operation process and help beginners understand the operation steps and identify typical anatomical structures. However, there are problems with single models and operations, which are not enough to deal with the complicated actual situations. At the same time, for the protection of the operator, it is difficult to use perspective equipment such as C-arm machines to simulate the precise positioning required in real conditions

Therefore, the current training guidance for young operators still relies on experienced operators to teach by example with the help of cadaver models, and the training coverage is small and the repeatability is poor

[0007] Based on the current training status of navigation and positioning technology and minimally invasive operation technology in spinal cord-related diseases, the following conclusions can be drawn: the application of navigation and positioning technology in the surgical treatment of spinal cord-related diseases is developing rapidly, and there are many related products and technologies , but there is still no navigation and positioning related equipment products that can take into account real-time, low cost, no or less radiation, and no or less damage. The development of ultrasound technology shows great potential, but the disadvantage of ultrasound images for bone imaging makes it further The development is facing a technical bottleneck; the training system for young operators is not perfect, and it relies heavily on the teaching of teachers and students, making it difficult to carry out extensive and independent development
