Example Embodiment

[0065] Example 1

[0066] The specific implementation of the eye socket 1 is directly printed from the digital model of the eye socket using 3D printing technology.

[0067] The digital model of the artificial eye seat is to obtain the digital imaging and communication (DICOM) data of the orbital bony structure and the orbital soft tissue of the patient's affected and healthy eyes through CT scanning, and the medical digital imaging of the orbital bony structure and the orbital soft tissue structure And communication (DICOM) data is divided, three-dimensional modeling and analysis, to build an individualized digital model.

[0068] The specific implementation takes the 3DMed medical image processing and analysis system as the development platform and the image segmentation algorithm as the core to develop an interactive image segmentation method.

[0069] The specific method of constructing the digital model of artificial eye seat is:

[0070] 1) Cut the volume data of DICOM data obtai...

Example Embodiment

[0101] Example 2: Animal experiment

[0102] Take the 3D printed hydroxyapatite artificial eye seat prepared in Example 1 as the experimental group, and the hydroxyapatite eye seat stent made of pore former as the control group, to evaluate the vascularization efficiency and eye seat mobility of the eye seat material . The result is Image 6 Shown: 3D printed hydroxyapatite artificial eye socket has a higher density of new blood vessels growing in it than the control group (A is the control group, B is the experimental group, the arrow shows the growing new blood vessels). Figure 7 Shown is the range of movement of the eye seat in all directions up, down, left and right after the artificial eye seat is implanted, indicating that the artificial eye seat has good mobility.

Abstract

The invention discloses an individualized 3D printing multifunctional artificial orbital implant and a preparation method thereof. The surface of the artificial orbital implant has a porous structure,the pores of the porous structure are circular pores, and the porous structure of the surface is arranged in a gradient manner, and the pores in the porous structure are arranged on the surface of the artificial orbital implant spaced apart; a special structure for fixing four extraocular muscles is arranged on the artificial orbital implant, the special structure consists of two elliptical holeswhich penetrate each other and are arranged close to each other, the preset sutures on the extraocular muscles pass through the two elliptical foramen and are knotted and fixed at the intersection of30 degree north latitude and 0 degree, 90 degree, 180 degree and 270 degree longitude respectively. The prosthetic orbital implant is printed directly by the digital model of the prosthetic orbital implant using 3D printing technology. The artificial orbital implant has high matching degree with the healthy eye and reduces the risk of exposure and infection after implantation of the orbital implant. The artificial orbital implant has good mobility and good simulation effect with individualized ophthalmic prosthesis, and has good clinical application value.

Description

technical field [0001] The invention relates to medical materials and a preparation method thereof, in particular to an individualized 3D printed multifunctional prosthetic eye seat and a preparation method thereof. Background technique [0002] Enucleation is currently the ultimate surgical treatment for absolute glaucoma, severe ocular rupture, and intraocular malignant tumors. Heavy mental and psychological burden. Selecting eye seat implantation to implant a suitable prosthetic eye seat to compensate for the loss of orbital content and wearing a suitable prosthetic eye piece is an ideal treatment plan to repair the missing eyeball and restore the appearance of the face. [0003] Most of the eye sockets used clinically are spherical eye sockets with a fixed shape, which cannot be selected individually according to the characteristics of the patient's own orbit. At present, the main cause of enucleation in China is ocular trauma. Patients with complex ocular trauma often...
