Abstract

A disposable mandrel and bladder is shown in which the mandrel is injected molded or machine fabricated in some other way that allows it to be permanently incorporated within the driver bladder of a surgical stapling mechanism. Supply line tubing is an integral part of the mandrel and would thus be permanently bonded to the bladder sub-assembly. Such configuration prevents tube clogging, bladder folding over infusion lines, and produces reliable firing of the stapler while using pneumatic driving mechanism.
