Abstract
Apparatus for microsurgical operations on the eye of a living being includes a housing having a compartment which receives a carrier module having a first support structure for conducting a passageway for supply of an irrigation fluid to a surgical site, a second support structure spaced laterally from the first support structure for conducting a second passageway for withdrawal of material from the surgical site, and at least one catch. The compartment which is subdivided in sections by spaced partition walls houses a pump for peristaltically transporting material in the second passageway, an interrupter unit for controlling the fluid flow through the first passageway, and a pull-in and locking mechanism which is engageable with the catch for pulling the carrier module into the compartment in a snap-like manner and releasably securing the carrier module therein such that the interrupter unit is in engagement with the first passageway and the pump is in engagement with the second passageway.
