Eye exenteration device and operation method thereof

Abstract

The present invention provides an eye exenteration device and an operation method thereof, and relates to the technical field of ophthalmic surgical instruments. The eye exenteration device comprisesa main body part and a movable part, wherein the movable part is an elastic part and can be bent relative to the main body part; the movable part surrounds the periphery of the main body part; the movable part is an arc-shaped ring, and the relatively small-diameter end of the arc-shaped ring is connected with the periphery of the main body part; in the direction away from the main body part, thediameter of the movable part is gradually increased; the main body part is provided with a first through hole and a second through hole, and the first through hole is used for insertion of a surgicalinstrument; and the second through hole is used for introduction of high-pressure gas. The whole device is put into the scleral cavity of which the eye preganglionic tissues have been removed, and thehigh-pressure gas is introduced in the scleral cavity through the second through hole, so that an intra-ocular pressure unit is suspended and the movable part closely clings to the inner wall of thescleral cavity; as the interior of the scleral cavity is kept in a high-pressure state, an operator can clean up residual retinas and choroids in the scleral cavity more quickly to avoid sympathetic ophthalmia.

Description

technical field [0001] The invention relates to the technical field of ophthalmic surgical instruments, in particular to a device for enucleating eye content and an operating method thereof. Background technique [0002] Compared with enucleation, enucleation of eye contents (also known as enucleation of eye contents) has many advantages. The operation time is relatively short, and it can reduce the atrophy of soft tissue in the orbit after operation and reduce the depression of the eye after surgery. At the same time, If proper implants are placed in the scleral cavity after the operation, the activity and appearance of the prosthetic eye will be better in the later stage. Therefore, the current enucleation surgery has become the first choice for many serious eye diseases. [0003] However, when the existing ocular content enucleation surgery removes the content of the eyeball, the residual retina and choroid (especially the optic disc) are often difficult to scrape off du...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for enucleation of eye contents and its operation method, so as to alleviate the residual retinal damage caused by the continuous bleeding in the eye when the existing eye contents enucleation operation removes the contents of the eyeball. And the choroid (especially the optic disc) is difficult to scrape clean, which increases the time-consuming operation and the technical problems of the risk of secondary sympathetic ophthalmia
