INDIVIDUALIZED 3D PRINTED ACETABULAR WALL DEFECT REPAIRING AND RECONSTRUCTING SYSTEM
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of acetabular wall defect reconstruction, and specifically relates to an individualized 3D printed acetabular wall defect repairing and reconstructing system.
BACKGROUND
[0002] At present, there are many methods for repairing and reconstructing acetabular wall defects. For simple acetabular bone defects, initial stability can be achieved through detrital bone grafting and cementless acetabular cup fixation. For severe acetabular bone defects, structural bone grafts or special acetabular internal fixation prostheses are usually selected. A prosthesis and treatment method which are most suitable for an individual often need to be selected according to preoperative evaluation. The complexity of the operation and the cost of the operation are increased. There are still some complications in the long-term after the operation.
[0003] In order to obtain a stable acetabulum, in addition to the intuitive means of bone grafting, some special internal fixation devices often need to be combined to increase its supporting strength. Especially for patients with acetabular defects above AAOS type III, how to repair the acetabulum with severe bone defects, restore its normal anatomical shape or position, and restore the support strength of the acetabulum is a very complicated problem. In addition, the shapes and extents of acetabular bone defects and the quality of bones are different. There is no unified mode for a reconstruction method that should be used for a defective acetabulum during the operation and of how to select a prosthesis for replacement. The treatment methods are still developing.
[0004] A 3D printing technology is based on a digital model file. It converts an abstract digital model into a three-dimensional physical model, thus lowering the preoperative preparations for difficult operations, simplifying the operation process, and improving the success rate of the operation. By formulating a preoperative prosthesis model, observing changes in anatomical structures of a lesion region has played a role in guiding the operation. Through individualized treatment and tailor-made individualized models, difficulties in a prosthesis placement position, correction of acetabular wall defects, etc. in joint replacement operations are simplified.
[0005] In summary, the current existing technology lacks an individualized 3D printed acetabular wall defect repairing and reconstructing system.

[0006] For the above-mentioned problems in the existing technology, the present disclosure provides an individualized 3D printed acetabular wall defect repairing and reconstructing system, including an image data acquisition processing module, a three-dimensional reconstructing and finishing module, a repairing and reconstructing module, and a 3D printing module, so as to perform individualized acetabular wall defect repair and reconstruction.

[0008] An individualized 3D printed acetabular wall defect repairing and reconstructing system includes an image data acquisition processing module, a three-dimensional reconstructing and finishing module, a repairing and reconstructing module, and a 3D printing module.

[0012] the 3D printing module prints the three-dimensional repairing and constructing model obtained by the repairing and reconstructing module to obtain a printed physical model.
[0013] Further, the mirror module obtains a three-dimensional reconstructing model for the acetabular defect of the lesion side by using an image theory according to the anatomic features of the healthy side acetabulum.
[0014] Further, the reverse engineering module performs segmentation by using Mimics software to obtain an independent three-dimensional virtual model of the 3D repairing and reconstructing system complementary to an acetabular defect region, so that the defective acetabulum is reconstructed into an intact acetabulum structure.
[0015] Further, the physical model includes amain body structural portion complementary to the defective acetabulum and an anchor structural portion used to enhance the stability; the main body portion repairs the defective acetabulum, and the anchor portion is embedded into the bone bed to play a role in fixing the reconstructing system and improving the initial stability.
