Abstract: An end effector for use with a surgical stapling instrument is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw to grasp tissue therebetween, and a staple cartridge. The staple cartridge comprises staples deployable into the tissue. The end effector further comprises a magnetic sensor configured to measure a parameter indicative of an identifying characteristic of the staple cartridge, an impedance sensor configured to measure a parameter indicative of an impedance of the tissue, and a processing unit in communication with the impedance sensor. The processing unit is configured to determine a property of the tissue based on an output of the impedance sensor.

Abstract: A surgical stapling instrument comprising an articulatable end effector including a staple cartridge is disclosed. The stapling instrument further comprises an articulation drive configured to articulate the end effector and a staple firing drive configured to fire the staples from the staple cartridge during a staple firing stroke. The articulation drive is selectively engageable with the staple firing drive to articulate the end effector and decoupled from the staple firing drive during the staple firing stroke. The stapling instrument further comprises a control system that is configured to compensate for the net displacement of the staple firing drive that occurs when articulating the end effector.

Abstract: A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

Abstract: An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a primary circuit. A supplementary power supply circuit configured to supply electrical power to a secondary circuit. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit. The supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

Abstract: A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.

IPC: A61B17/072

Abstract: A surgical stapling instrument comprising a tissue cutting knife movable through a staple cartridge to perform a staple firing stroke is disclosed. The stapling instrument further comprises a lockout system configured to prevent the tissue cutting knife from being moved through the staple firing stroke if the staple cartridge is missing from the stapling instrument and/or if the staple cartridge has been previously fired. The lockout system comprises a flexible spring that acts on the bottom of the tissue cutting knife at the initiation of the staple firing stroke to push the tissue cutting knife into a lockout recess if the staple cartridge is missing or has been previously fired.

Abstract: A surgical instrument includes a drive member movable by a drive motor between a home position and an end of stroke. A mechanical stop is disposed at or near the end of stroke and is structured to increase resistance to movement of the drive member from a first position to a second position. A control system detects a current spike associated with the increased resistance and interrupts power to the drive motor.
