BATTERY PACK INCLUDING A CIRCUIT INTERRUPTER

A battery pack for use with a surgical instrument is disclosed. The battery pack comprises a battery housing, batteries positioned in the battery housing, and an interruption member. The battery housing includes electrical contacts configured to electrically couple the battery pack to the surgical instrument when the battery pack is attached to the surgical instrument. The interruption member is movable from a first position where the interruption member electrically disconnects at least one battery from another battery and a second position. The batteries are electrically connected to the surgical instrument when the interruption member is moved from the first position to the second position and the battery pack is attached to the surgical instrument.

Local display of tissue parameter stabilization

A powered surgical stapling assembly comprising a motor, an end effector, a sensor, a display, and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw movable relative to the first jaw. The end effector is configured to clamp tissue between the first jaw and the second jaw. The sensor is configured to measure a parameter of the tissue clamped within the end effector. The control circuit is configured to monitor the parameter sensed by the sensor and identify when the monitored parameter stabilizes within a stabilization range. The monitored parameter is considered stable when a rate at which the monitored parameter changes falls below a predetermine threshold rate of change. The control circuit is further configured to display to a user when the parameter stabilizes.
