Problems solved by technology

[0003] At present, the commonly used restoration method in China is to implant orbital implants after removing the eyeballs at any age, or to implant orbital implants for children without eyeballs, but these implants are difficult to recover after implantation. It is a fixed size and cannot increase with the development of the child, and cannot continuously stimulate the growth of the orbit and conjunctival sac
Moreover, these implants require surgical implantation, and there are surgical risks and postoperative complications, so they ...

Embodiment Construction

[0028] like figure 1 As shown, the manufacture method of the orbit and conjunctival sac growth stimulating device of the technical solution of the present invention comprises the following steps:

[0029] Step S1: Obtain the morphological data of the conjunctival sac and orbit on the affected side, mainly including the height, depth and three-dimensional shape of the conjunctival sac.

[0030] Step S2: reconstructing the three-dimensional model data of the affected eye orbit based on at least the shape data of the affected conjunctival sac and orbit.

[0031] Step S3: importing the three-dimensional model data of the affected eye orbit into a three-dimensional printer.

[0032] Step S4: The orbital and conjunctival sac growth stimulating device is printed out by the three-dimensional printer using materials with biocompatibility and plasticity.

[0033] The technical solution of the present invention will be described in detail below in conjunction with the embodiments.

Abstract

The technical solution of the present invention discloses a method for manufacturing an eye orbital and conjunctival sac growth stimulation device, including: obtaining the conjunctival sac and orbital shape data of the affected side; reconstructing the three-dimensional model data of the affected eye orbit based at least on the affected side's conjunctival sac and orbital shape data ; importing the three-dimensional model data of the affected side orbit into a three-dimensional printer; using materials with biocompatibility and plasticity to print out the orbit and conjunctival sac growth stimulating device through the three-dimensional printer. The technical scheme of the invention is simple and safe, does not require surgical implantation, is convenient to wear, and the patient feels comfortable after wearing it, without obvious adverse reactions, can fully stimulate the growth of the orbit and conjunctival sac, and has good cosmetic effect.

Description

technical field [0001] The invention relates to the field of ophthalmic medicine, in particular to a method for manufacturing an orbital and conjunctival sac growth stimulating device. Background technique [0002] Congenital microphthalmia and anophthalmos are common congenital blinding eye diseases in my country, and acquired microphthalmia and anophthalmos patients are more common in clinical practice due to ocular trauma and ocular malignant tumors leading to eyeball atrophy and enucleation. Under normal circumstances, from birth to adulthood, the eye sockets and skull bones develop together in a certain proportion, and at the same time, they also adapt to and satisfy the doubled eyeball volume during development. For children with microphthalmia and no eyeballs during development, if reasonable orbital development interventions are not carried out in time, facial deformities will be caused, which will seriously damage the patient's facial appearance. This is the main re...
