Abstract

The invention belongs to the technical field of craniomaxillofacial surgeries, and particularly relates to an individualized craniomaxillofacial region navigating and registering guide plate and a registering method thereof. The individualized craniomaxillofacial region navigating and registering guide plate comprises a biteplate and registering mark points, wherein the registering mark points arecones of which the diameter is 1mm and of which the depth is 1mm. Design is performed through a computer, the main structure of the individualized craniomaxillofacial region navigating and registering guide plate comprises two parts, namely a biteplate part which can be in close contact with maxillary dentition and the registering mark points which are in discrete distribution at the flank and the wing of the guide plate and which are used for point registering. A patient only needs to be subjected to shooting of imaging examination once during preliminary diagnosis, so that secondary radiation injury can be avoided; and besides, a plaster model of the maxillary dentition is prepared. The individualized craniomaxillofacial region navigating and registering guide plate is a novel guide plate, and a computer assisted design technique, a three-dimensional printing technique and a navigation technique are combined; and according to the corresponding registering method of the individualized craniomaxillofacial region navigating and registering guide plate, systematic registration is completed through the registering mark points in virtual design, and the registering method is an innovative registering method.

Description

technical field

[0001] The invention belongs to the technical field of craniomaxillofacial surgery, and in particular relates to an individualized craniomaxillofacial navigation and registration guide plate and a registration method thereof. Background technique

[0002] Registration is an important process in the implementation of surgical navigation techniques. As the key core technology in optical navigation, registration technology is directly related to the accuracy of the whole system and the success or failure of computer-assisted surgery. The so-called registration refers to the virtual coordinate system, that is, the coordinate system formed in the computer image space after the single-mode or multi-mode medical images such as CT and MRI acquired before the operation are processed in the computer image space, and the world coordinate system, that is, the navigation during the operation. The coordinate system constructed by the positioning device of the system and t...
