SURGICAL STAPLER WITH INCOMPLETE FIRING INDICATOR

摘要

A surgical instrument includes a stapling head assembly, an anvil, a firing assembly, a load sensor, and an indicator. The firing assembly actuates the stapling head assembly to drive an annular array of staples through tissue toward the anvil. The load sensor is operable to sense a load in the firing assembly while the firing assembly actuates the stapling head assembly. The indicator is operable to provide feedback based on the load sensed by the load sensor. The firing assembly may include a longitudinally translatable member. The instrument may further include a position sensor that is operable to sense a longitudinal position of the translatable member while the firing assembly actuates the stapling head assembly. The indicator may be activated based on data from at least one of the sensors indicating completion or failure of a full actuation stroke of the firing assembly.
