Prosthesis replacement surgery simulation system based on mixed reality technology and construction method

Abstract

The invention relates to the technical field of medical informatization, in particular to a spinal prosthesis replacement surgery simulation system based on a mixed reality technology and a construction method, and the method comprises the following steps: (1) establishing a prosthesis data cloud storage library, and recording and storing images and data information of spinal prosthesis models ofvarious parameters; step (2), scanning a human spine image, including a CT scanning image or a nuclear magnetic scanning image; (3) carrying out human body spine image import and three-dimensional image modeling; (4) controlling the three-dimensional digital model of the human body spine image on the MR intelligent equipment; (5) calculating prosthesis parameters; step (6), calling a spinal prosthesis 3D model; step (7), carrying out prosthesis replacement effect evaluation; and (8) automatically matching the human body spine three-dimensional digital model with the patient. The precision andspeed of the prosthesis replacement operation can be improved, the operation time is shortened, and the operation pain is relieved.

Description

technical field [0001] The invention relates to the technical field of medical information technology, in particular to a simulation system and construction method for prosthesis replacement surgery based on mixed reality technology. Background technique [0002] The spine is the most important part of the human body. The problems of the body all come from the nervous system, because the nervous system controls endocrine and controls the internal organs and other organs. Whether the nervous system is normal or not will be affected by the bone structure. The central nervous system of the human nervous system Including the brain and spinal cord, the spinal cord is located in the spinal canal, the peripheral nervous system contains 12 pairs of cranial nerves and 31 pairs of spinal autonomic nerves, and most of the cranial nerves and all spinal nerves pass through the middle of the spine (spinal canal). , it will oppress the nerves and affect the normal regulatory function, thus...

Problems solved by technology

[0003] The importance of the spine to the human body is self-evident. The treatment of the spine is also an important and difficult point in the medical field. Due to the dense blood vessels and nerves around the spine, the operation is more difficult and complicated.

In traditional spinal prosthesis replacement surgery, the images generated by CT or MRI are two-dimensional. Due to limitations in imaging technology and display methods, it is necessary to reconstruct the surgical site in the brain based on the doctor's personal clinical experience and spatial imagination. The actual anatomical structure of the prosthesis, and the effect of the prosthesis implantation is observed through the test of the prosthesis implantation in the spine, but there is a big gap between the two-dimensional medical image and the three-dimensional surgical scene, and the prosthesis implantation test will also lead to a longer operation time , aggravate the pain and injury of patients, so there are certain difficulties and errors in the application of traditional imaging techniques and surgical methods
