Apparatus for microsurgical operations on the eye of a living being

Apparatus for microsurgical operations on the eye of a living being, comprising:

• a housing having a compartment;
• a carrier module insertable in said compartment and including a first support structure conducting a first passageway for supply of an irrigation fluid to a surgical site and a second support structure spaced laterally from said first support structure and conducting a second passageway for withdrawal of material from the surgical site;
• pump means accommodated in said housing for peristaltically transporting material in said second passageway;
• fluid control means cooperating with said first passageway for selectively interrupting a fluid flow through said first passageway;
• and
• pull-in and locking means for releasably securing said carrier module in said compartment in such a manner that in operational position of said carrier module said fluid control means is in engagement with said first passageway and said pump means is in engagement with said second passageway,
• said pull-in and locking means including a catch secured to said second support structure of said carrier module at one end facing said compartment of said housing, and a locking member arranged inside said compartment and having one end configured to receive said catch and another end swingably mounted for rotation of said locking member between a receiving position in which said one end receives said catch and a fixing position in which said locking member turns about its pivot axis to automatically pull said catch with said carrier module into said compartment for securely aligning said carrier module in the operational position in said compartment.
