Problems solved by technology

[0004] Due to the non-linear structure of the maxillofacial region, the anatomical structure is complex and highly variable, conventional positioning and tracking technology needs to implant fixation pins in the cranial trauma, and then use related technologies for positioning and tracking, which increases surgical trauma and operation

Example Embodiment

[0033] Example 1

[0034] A 3D printing-based replaceable tooth-supported personalized maxillofacial augmented reality positioning and tracking device, including a bite guide and a visual capture sign module, the visual capture sign module is provided with a retainer, a connector and a replaceable The visual capture mark, the bite guide plate is connected with the retainer, and the retainer and the replaceable visual capture mark are connected by the connecting body to form a whole. The retainer is hollow and is connected with the connector in a semi-fixed manner.

[0035] The connection angle between the visual capture sign module and the connecting body is designed accordingly for different parts, and different angles can also be designed in the same case, which can be replaced during the operation according to the specific situation. The connector plays the role of connecting, which is beneficial to reduce the visual sign outside the scope of the operation, and at the same time...

Abstract

The invention relates to the related field of oral-maxillofacial surgical medical apparatus and instruments and augmented reality technologies, in particular to a tooth-borne type maxillofacial augmented realitypositioning tracing device based on three-dimensional printing. The device is characterized by comprising an occlusion guide plate and a vision capture marking module, the vision capture marking module is provided with a retention body, a connection body and a replaceable vision capture mark, the occlusion guide plate is connected with the retention body, and the retention body and thereplaceable vision capture mark are integrally connected through the connection body. The tooth-borne type maxillofacial augmented reality positioning tracing device based on three-dimensional printing is simple in structure, convenient to operate, low in cost, portable and efficient, accurate positioning and dynamic visualization are achieved, the device is beneficial for the maxillofacial surgery, and the good effect is achieved.

Description

technical field [0001] The invention relates to the field of oral and maxillofacial surgical medical instruments and augmented reality technology, in particular to a tooth-supported maxillofacial augmented reality positioning and tracking device based on 3D printing. Background technique [0002] Traditional maxillofacial surgery is determined entirely by the experience and judgment of the surgeon, so the success or failure of the operation largely depends on the mastery of the local anatomical structure by the surgeon. For young doctors or cases with large local structure variations, The difficulty of the operation is greatly increased, which seriously affects the effect of the operation and even prolongs the time of the operation. [0003] With the rapid development of digital technology in oral and maxillofacial surgery, methods such as digital guide plate and surgical navigation have emerged for the positioning and tracking of intraoperative anatomical structures, but th...
