Sacrum nerve puncture path simulation planning system and device

Abstract

The invention provides a sacrum nerve puncture path simulation planning system and device, and relates to puncture operation simulation. The sacrum nerve puncture path simulation planning system comprises an image obtaining module and a path simulation planning module, and the image obtaining module is configured to obtain scanning images of sacrum, sacral foramen and a positioning grid located at a lumbosacral part; and the path simulation planning module is configured to establish a three-dimensional model of the sacrum, the sacral foramen and the positioning grid according to the scanned image, and acquire a virtual puncture path penetrating through the positioning grid to reach a sacrum set position and an intersection point of the positioning grid and the virtual puncture path according to the three-dimensional model. The problems that at present, sacral nerve holes are directly punctured for many times, and pain of patients is large are solved. By acquiring the scanning images of the positioning grid, sacrum and sacral foramen, taking the positioning grid as a positioning reference, reconstructing the three-dimensional model of the sacrum, the sacral foramen and the positioning grid, taking a reference of penetrating through the positioning grid to reach a sacrum set position, and establishing a plurality of virtual puncture paths, a human organ state and an actual puncture process are simulated.

Description

technical field [0001] The present disclosure relates to the field of puncture operation simulation, in particular to a sacral nerve puncture path simulation planning system and device. Background technique [0002] Sacral neuromodulation is a long-term neuromodulation surgery that is placed in the body. During the operation, electrodes need to be placed in the nerve foramen of the sacrum to improve urination and defecation dysfunction. [0003] Interventional therapy is a common minimally invasive treatment method for sacral neuromodulation surgery, and puncture is performed under the development of medical imaging equipment; sacral neuromodulation surgery generally uses X-ray assisted positioning, and X-ray exposure time is long, and, due to the Accuracy problems lead to more punctures and longer operation time for patients with greater pain. At present, although it is possible to collect images multiple times, plan and optimize the puncture path in advance, and then perf...

Problems solved by technology

[0003] Interventional therapy is a common minimally invasive treatment method for sacral neuromodulation, and puncture is performed under the development of medical imaging equipment; sacral neuromodulation surgery generally uses X-ray assisted positioning, and X-ray exposure time is long, and, due to the Accuracy problems lead to many punctures, longer operation time and greater pain for patients

At present, although it is possible to collect images multiple times, plan and optimize the puncture path in advance, and then perform actual punctures based on the optimal path to solve the problem of more puncture times, the establishment of multiple feasible puncture paths requires manual design. , its feasibility verification under the planar image cannot fully reflect the actual state of human organs; and in the actual operation process, it is still necessary to reposition the starting point and end point of the puncture, and then perform the puncture, which still has long exposure time and surgical Problems that cause greater pain for patients over a long period of time
