Abstract

The invention discloses an adjustable conjunctival sac expander and a method for expanding a conjunctival sac through the adjustable conjunctival sac expander. The conjunctival sac expander comprises two supporting modules used for expanding the conjunctival sac, the two supporting modules are oppositely arranged, and the outer surfaces of the two oppositely-arranged supporting modules are the outer surfaces of protruding balls. The two oppositely-arranged supporting modules are fixed together through an adjusting device which is used for supporting and is capable of adjusting the distance between the two supporting modules. The length of an eye shaft is determined, the size of the conjunctival sac expander is determined, the conjunctival sac expander is placed in the conjunctival sac, the distance between the two supporting modules is expanded at regular intervals through the adjusting device, the conjunctival sac expander is taken out until the needed expansion degree of the conjunctival sac is reached, and an ocular prosthesis sheet is mounted. The adjustable conjunctival sac expander is used for expanding the conjunctival sac, the ideal expansion effect can be achieved, and the problem that the ocular prosthesis sheet cannot be mounted after the conjunctival sac is narrow can be effectively solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a conjunctival sac dilator whose expansion degree can be adjusted. Background technique [0002] Conjunctival sac stenosis is a common problem in eye cosmetics (installation of prosthetic eye tablets), and there are many reasons for this problem. Severe conjunctival sac stenosis is more common in: (1) Various ocular traumas, especially acid and alkaline chemical injuries and thermal burns, when the eyeball is enucleated, the conjunctival sac scar shrinks and the conjunctival sac shrinks. (2) Congenital microphthalmia and no eyeball. (3) Those who had their eyeballs removed due to ocular malignancy, inflammation, etc. when they were young, but did not wear prosthetic eyes in time, or underwent postoperative radiation therapy that affected eye development. (4) Long-term exposure of the prosthetic eye platform destroys the integrity of the conjunctiva. The conjunctival sac defect a...
