Abstract
A retractable ophthalmic surgical tool includes a shell, slidable insert, slide button, spring, and blade. The shell is preferably a hollow tube. A first slot is formed through the wall of the shell at substantially a first end thereof. A second slot is formed through the wall of the shell at substantially a middle of the shell length. A connecting slot is formed between the first and second slots to enable the slide button to be slid therebetween. The slidable insert includes a body, a first cantilever arm, and a second cantilever arm. The blade is preferably inserted into a first end of the body. The first cantilever arm extends from substantially a middle of said body and the second cantilever arm extends from an end of the first cantilever arm. The slide button is attached to a top of the second cantilever arm at assembly. At least one side of the body has a groove formed therein to provide clearance for the spring. A hole is formed through a middle of the body for attachment of one end of the spring. An end plug is inserted into a second end of the shell for attachment of the other end of the spring.
