Abstract

A surgical stapling system includes an adapter assembly, a trocar assembly attachable to the adapter assembly, a processor, and memory. The memory includes instructions executable by the processor to cause the trocar assembly to move relative to the adapter assembly and determine whether the trocar assembly is properly attached to the adapter assembly. Such determination is based on an amount of force applied between the trocar assembly and the adapter assembly, an amount of current detected in the surgical stapling system, or an amount of time the trocar assembly moves relative to the adapter assembly without an indication that the amount of force is within a predetermined range.
