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 that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

Abstract: An input control device is disclosed. The input control device can be configured to operate in different modes depending on proximity data provided by a proximity detection system. The input control device can include a feedback generator configured to generate feedback in response to the input control device switching between operational modes, the proximity data provided by the proximity detection system, and/or other conditions of the surgical procedure, robotic surgical tool, surgical site, and/or patient. The input control device can include a variable resistance assembly for resisting input control motions applied to an actuator thereof. Additionally or alternatively, the input control device can include an end effector actuator assembly for repositioning the end effector actuator based on feedback from a paired robotic surgical tool.

Abstract: In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

Abstract: A surgical stapling instrument comprising a housing, a shaft, an end effector, a first articulation joint configured to permit the end effector to be articulated in a first plane, a second articulation joint configured to permit the end effector to be articulated in a second plane, and a staple firing drive is disclosed. The end effector comprises a distal end, a proximal end, a first jaw, a second jaw rotatable relative to the first iaw, and a staple cartridge. The staple firing drive comprises a firing member and a flexible drive tube extending through the first articulation joint and the second articulation joint. The firing member comprises a first cam, a second cam, and a round attachment aperture. The flexible drive tube comprises a longitudinal length, an outer circumference, a distal end seated in the round attachment aperture, and interlocking cuts in the outer circumference extending longitudinally and circumferentially.

Abstract: A stapling assembly comprising a first jaw, a second jaw, an elongate channel configured to receive a staple cartridge, a firing member configured to perform a firing stroke, a biasing element, and a rotary drive shaft is disclosed. The staple cartridge comprises staple cavities, staples, staple drivers, and a sled. The firing member comprises a cutting edge, a first camming member, and a second camming member. The biasing element comprises a spring and is movable between an initial position and a displaced position. The rotary drive shaft is movable between a first position and a second position relative to the elongate channel. The rotary drive shaft is moved from the first position to the second position by the staple cartridge when the staple cartridge is inserted into the elongate channel and moves the biasing element to the displaced position against a distal biasing force of the spring.
