Problems solved by technology

During the osteotomy process, there is loss of bone tissue caused by the saw blade. During the adjustment process, the accumulated errors in the adjustment of multiple bone sections will be enlarged with the increase of the defect, which will eventually lead to certain differences between the condyle, mandibular angle and other marking points and the design plan. deviation

Embodiment Construction

[0022] The method for quickly switching the relationship between the titanium plate and the osteotomy guide plate will be further described in detail below. Wherein, some well-known structures and terms thereof in the accompanying drawings are understandable to those skilled in the art, and will not be described in detail here. In addition, the examples in this embodiment only focus on introducing the relevant parts related to the conversion of the titanium plate-guide plate relationship, and other contents such as virtual surgery design and surgical operation are only briefly explained.

[0023] In order to realize the rapid conversion of the space position between the titanium plate of the jaw bone and the osteotomy guide plate, the specific method is as follows:

[0024] ① After collecting CT and other image data of the patient, use 3D design software to create a 3D data model of the patient's jaw.

[0025] ②Design the osteotomy guide plate 2 according to the extent of the...

Abstract

A method for quickly converting the spatial position of a titanium plate-osteotomy guide plate for mandibular surgery, the invention relates to a method for converting the relationship between a titanium plate-osteotomy guide plate. By drilling holes on the reconstructed model according to the pre-bent titanium plate and reverse drilling, the nail hole information of the titanium plate can be retained on the osteotomy guide plate. Before the malignant tumor osteotomy, the position of the titanium plate hole can be determined without destroying the tumor structure. After the complete resection of the tumor tissue, the titanium plate is fixed in place to maintain the original spatial position of the mandibular bone blocks on both sides, which can avoid mandibular damage caused by the accumulated errors of multiple bone surface adjustments during the bone block placement process. A change in spatial position between bone fragments.

Description

technical field [0001] The invention relates to the conversion of the spatial position between the guide plate and the titanium plate in the process of computer-aided jaw repair and reconstruction, and in particular relates to how the space position of the bone block determined by the guide plate is quickly transferred to the titanium plate. Background technique [0002] At present, computer-aided digital jaw repair and reconstruction has greatly shortened the operation time of jaw repair and reconstruction, improved surgical accuracy, and reduced the occurrence of complications. Through osteotomy guide plate, bone extraction guide plate, reconstruction guide plate and other auxiliary devices, the operation plan is made before the operation. During the operation, the diseased bone is cut according to the design, free bone is cut from other parts of the patient’s body, and the diseased part is repaired and reconstructed. Titanium plate fixed. Due to the special anatomical st...
