Embodiment Construction

[0050] With a certain precision, the human skull can be regarded as a symmetrical structure. Orbital blowout fracture surgery is necessary only when it reaches a certain level, so hypothesis 1 is put forward. Under the premise that orbital blowout fracture requires surgery, the displacement of the bone wall exceeds 3 mm, which can be clearly reflected on the CT image. . At the same time, by using the Mimics software to reconstruct the 3D model of the skull, the difference between the inner wall of the damaged eye socket and the inner wall of the undamaged eye socket can be found, such as figure 1 The undamaged orbit is shown with a smooth orbital wall, and the damaged orbit is shown as figure 2 As shown, there are obvious depressions.

[0051] refer to Figure 8 , a method for prefabricating a titanium mesh for orbital wall blowout fractures, the method comprising the following steps:

[0052] Step 1. Establish the patient's skull model

Abstract

The invention belongs to the field of medical instruments, and particularly relates to an orbital blow-out fracture titanium mesh prefabrication method which includes the steps: 1 building a patient skull model; 2 performing cutting and separation; 3 performing mirroring; 4 performing reset and readjustment; 5 improving the coincidence level of a determined damaged area and an actual damaged area; 6 accurately determining the damaged area of a patient; 7 building a repair sclerite model according to the damaged area; 8 printing repair sclerite in a 3D (three-dimensional) manner. The fracture area calculated by the orbital blow-out fracture titanium mesh prefabrication method approximates to actual precision medicine, and precision medicine serving as next-generation diagnosis and treatment technology has important theoretical and practical significance. As the curvature and the size of the sclerite fit with the damaged area of the patient, surgical effects are improved, postoperative complications are decreased, sclerite fabrication is finished before a surgery, surgical time is shortened, and accident risks caused by too long surgical time are reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a method for prefabricating a titanium mesh for orbital wall burst fracture. Background technique [0002] With the gradual acceleration of my country's modernization and the rapid development of economy, technology and society, the incidence of orbital burst fractures is gradually increasing due to traffic accidents, industrial and agricultural production, and some violent behaviors. Titanium mesh implantation can be used to treat blowout fractures of the medial and inferior orbital walls. At present, there are three commonly used methods of making titanium mesh and all of them have disadvantages: 1. The traditional titanium mesh used to repair orbital wall burst fractures is bent and cut according to the observation of the surgeon during the operation; It is made according to what the surgeon sees during the operation. The effect of the operation is related to the doctor's condi...
