Abstract

A stapling instrument system is disclosed that comprises an instrument comprising a handle and an output and, in addition, an interchangeable tool assembly attachable to the instrument. The interchangeable tool assembly comprises a housing, a drive input operably engageable with the output, and an end effector comprising a first rotatable output shaft, a second rotatable output shaft, and a transmission configurable in three operating states which selectively couple the first and second rotatable output shafts with the drive input.

Claims

an instrument comprising a handle and an output; and

an interchangeable tool assembly attachable to said instrument, comprising;

a housing;

a drive input operably engageable with said output; and

an end effector, comprising;

a first rotatable output shaft;

a second rotatable output shaft; and

a transmission configurable in three operating states;

a first operating state in which said drive input is operably coupled with said first rotatable output shaft and operably decoupled from said second rotatable output shaft;

a second operating state in which said drive input is operably coupled with said second rotatable output shaft and operably decoupled from said first rotatable output shaft; and

a third operating state in which said drive input is operably coupled with said first rotatable output shaft and said second rotatable output shaft.
