Abstract

The invention discloses a jaw bone positioning system and method for maxillofacial surgery. The system comprises a personalized jaw fork, a registration frame, a reference frame, a mechanical arm anda control module, and the control module can receive pose information from the registration frame, the reference frame and the like and three-dimensional data of a target object and can control the mechanical arm to position a jaw bone block needing to be positioned at the target position. The application of the system is beneficial to accurate implementation of surgery, the safety and controllability of the surgery are improved, deviation caused by human hands and subjective judgment errors in the operation is avoided, and the surgery efficiency is improved. The jaw bone positioning method disclosed by the invention has the effect corresponding to that of the jaw bone positioning system.

Description

technical field [0001] The invention relates to the field of oral medical equipment, in particular to the field of robot-assisted surgery in oral medical equipment, and in particular to a jaw positioning system and method in oral and maxillofacial surgery orthognathic surgery. Background technique [0002] Orthognathic surgery achieves the purpose of treating dental and maxillofacial deformities by osteotomizing, moving and refixing the jaw bone with disordered structure. When the bone block is moved, the original anatomical reference landmarks disappear or are difficult to locate. The traditional treatment mode uses the experience of model surgery and doctors to locate. Among them, the model surgery method introduces large errors and the treatment effect is uncontrollable. The bone shape of the oral and maxillofacial region is complex, which has a great impact on the appearance. At present, the virtual maxillofacial surgery process can be virtualized by computer-aided desig...
