Problems solved by technology

Therefore, there is a mismatch between the postoperative prosthetic eye platform, which may form a contrast with the fellow eye and affect the appearance. If the deviation is large, the patient will choose to re-operate for adjustment.
At the same time, the choice of prosthetic eye piece has disadvantages such as mismatch with the color and shape of the fellow eye, which affects the postoperative effect and aesthetics.
Moreover, after the implantation of the prosthetic eye table is stable, the prosthetic eye is clamped into the eyelid, but if the conjunctival sac is poorly formed, this clamping is not stable
In addition, in terms of design details, the traditional prosthetic eye platform is a simple sphere, and there are defects such as the lack of fixing the rectus muscle and the position of the prosthetic eye piece. Natural materials such as coral and hydroxyapatite also have the risk of rejection to varying degrees, resulting in prosthetics. Serious complications such as eye socket exposure
[0005] With the improvement of people's needs, the safety and accuracy requirements of plastic surgery are getting higher and higher. The traditional prosthetic eye platform and its implantation methods can no longer meet the needs of patients, and urgently need to be improved.

Embodiment 1

[0081] Example 1 Preparation of artificial eye stand

[0082] Use B-ultrasound, three-dimensional CT, three-dimensional color Doppler ultrasound and other detection methods to detect the spatial images of the patient’s healthy eye and the affected eye, and obtain the diameter of the normal eyeball, the diameter of the orbit, the distance between the eyeball and the orbit, and the diameter of the orbit of the affected eye. According to the test data, reconstruct the three-dimensional space structure of the artificial eye socket to match the affected eye, and design the reconstructed three-dimensional artificial eye socket model to have a certain spatial structure, such as figure 1 Shown:

[0083] The designed artificial eye base mimics the spatial structure of coral reef pores (pore diameter 0.2mm); the porous space structure is conducive to the vascularization of biological tissues after transplantation of the artificial eye base, and provides sites for the attachment of muscles and...

Abstract

The invention relates to the field of prosthesis products, in particular to an ocular prosthesis base and a preparation method thereof, and an ocular prosthesis and a preparation method thereof. Ocular prosthesis implant matching loci, rectus suture loci and a porous space structure are arranged on the ocular prosthesis base. The ocular prosthesis base is high in matching degree with a healthy eye, high in comfort level, high in safety and slight in postoperative rejection, and can achieve the effects of promoting growth of cells and tissues, diminishing inflammation and promoting postoperative recovery; magnetic matching loci of the ocular prosthesis base and an ocular prosthesis implant are convenient for wearing and positioning the ocular prosthesis implant; and meanwhile, due to movement of the ocular prosthesis base, movement of the ocular prosthesis implant can be driven, and a super-simulation effect is achieved.

Description

Technical field [0001] The invention relates to the field of prosthetics products, in particular to an artificial eye stand and a preparation method thereof, an artificial eye and a preparation method thereof. Background technique [0002] Ophthalmology trauma, eye tumors and other major diseases often lead to eyeball removal. In order to improve the quality of life of patients after surgery and maintain the appearance of the eye after surgery, it is necessary to perform an eye implant surgery after eyeball removal to fill the eyeball removal After the surgery is healed, an artificial eye piece is implanted. The artificial eye piece simulates the iris and pupil, making the overall appearance similar to the real eye. The artificial eye table and the artificial eye piece form the entire artificial eye. [0003] An artificial eye is a kind of prosthetic product. Wearing an artificial eye does not restore the patient's vision, but is a remedy for facial defects. The artificial eye con...
