An adapter assembly for connecting a loading unit to a handle assembly, the adapter assembly comprising:
- an elongate body including an outer sleeve;
- a trocar assembly releasably securable with the elongate body, the trocar assembly including a trocar housing defining first and second openings;
- and
- a retaining mechanism configured to releasably secure the trocar assembly within the elongate body, the retaining mechanism including first and second button members configured for operable engagement by a user, the first and second button members are moveable between a lock position in which the trocar assembly is securely received with the outer sleeve and a cleanse position in which the first and second button members extend beyond the outer sleeve, wherein the first and second button members are secured directly to one another to maintain the first and second button members with the elongate body.
