Abstract

The invention discloses an internal fixed steel plate preoperative designing and prefabricating method based on augmented reality. The method comprises the steps: interactively regulating planes by users, indicating symmetry planes of a human body, replacing body data of hurt side with body data of the unhurt side, and conducting simulated reconstruction on fracture parts; delineating and designing a reconstructed steel plate trace on the surface of the reconstructed bone, and generating a triangular grid three-dimensional model of the reconstructed steel plate according to the reconstructed steel plate trace; and overlapping and drawing the generated three-dimensional steel plate model on a video image collected in real time, controlling the posture of the three-dimensional model of the steel plate by using an augmented reality optical marker, regulating the model postures by users, observing the coincidence degree of the real steel plate and a virtual steel plate, thus completing the shaping of the steel plate. The method saves the operation time, shortens the treatment courses, reduces the occurrence of complications and improves the cure rate.

Description

technical field [0001] The invention belongs to the technical field of internal fixation plates, and in particular relates to a method for preoperative design and prefabrication of internal fixation plates based on augmented reality. Background technique [0002] Complex pelvic fracture refers to a severe trauma, mostly caused by direct violent pelvic compression, resulting in multiple (≥2) pelvic ring damages involving the pubic bone, ischium, ilium, and acetabulum, resulting in normal pelvic fractures. The integrity of the structure is damaged, and acetabular fractures are joint fractures, so the principle of treatment should be anatomical reduction. [0003] In the reduction and internal fixation of pelvic and acetabular fractures, the bone anatomy is complex, individual differences are large, the fracture site is deep, surrounded by important nerves and blood vessels, the position is poor during the operation, and insufficient experience in the operation. Orthopedic sur...
