Manufacturing method of orbit and conjunctiva sac growth stimulation device

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...

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 are not the best choice

Some people also use the method of directly wearing prosthetic eye tablets in the conjunctival sac, but the shape of the prosthetic eye film cannot be customized, so the entire orbit and conjunctival sac cannot be stimulated regularly or evenly, and there are always blind spots of stimulation. The prosthetic eye film uses Resin material is hard, uncomfortable to wear, and needs to be hand-grinded. Children generally need to replace larger prosthetic eye pieces after 3-6 months. It is very inconvenient to make and wear
