Monitoring of multiple sensors over time to detect moving characteristics of tissue
A surgical instrument includes a wireless transmission system for transmitting at least one of power and a data signal through between an end effector and an instrument housing of the surgical instrument. The surgical instrument includes the sensor monitoring and processing circuit.
Stapling instrument comprising a signal antenna
A staple instrument system comprising a cartridge body and an antenna is disclosed.
ADJUSTABLE COMMUNICATION BASED ON AVAILABLE BANDWIDTH AND POWER CAPACITY
Disclosed is a surgical instrument, comprising: an end effector configured to grasp tissue. The end effector comprises a jaw, and a staple cartridge seatable in the jaws, wherein the staple cartridge comprises a sensor array. The surgical instrument further comprises a power source configured to supply power to the staple cartridge, and a transmission system configured to wirelessly transmit at least one of the power and a data signal between the staple cartridge and the surgical instrument, and a control circuit. The control circuit is configured to detect a bandwidth of data transmission through the transmission system, detect a discharge rate of the power source, and select a sensor sampling rate of the sensor array based on a detected value of the bandwidth and a detected value of the bandwidth and a detected value of the discharge rate.
SURGICAL INSTRUMENT WITH FASTENER PRELOAD LOCK-OUT
Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a removable preload lock-out attached to the elongated shaft to prevent the follower from applying a preload to the fasteners.
MONITORING OF INTERNAL SYSTEMS TO DETECT AND TRACK CARTRIDGE MOTION STATUS
A surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.
Stapling assembly comprising a retraction drive
A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.
STAPLE CARTRIDGE IDENTIFICATION SYSTEMS
A surgical stapling system comprising an instrument interface comprising a control circuit and an RFID reader is disclosed. The surgical stapling system further comprises a shaft assembly comprising a shaft and an end effector. The end effector comprises a first jaw, a second jaw, an anvil, and a cartridge channel. The surgical stapling system further comprises a replaceable staple cartridge assembly removably positioned within the cartridge channel. The replaceable staple cartridge assembly comprises a cartridge body, a longitudinal slot, a plurality of staple cavities, a plurality of staples, and a staple cartridge retainer. The staple cartridge retainer comprises a rib, a body portion, and an RFID tag embedded within the body portion, wherein the RFID tag comprises a memory, wherein the memory comprises identifier information stored in the memory specific to the staple cartridge, and wherein the identifier information is accessible by the RFID reader.
SURGICAL STAPLING DEVICE WITH FIRING LOCKOUT
A surgical stapling device includes an anvil section, a cartridge section, a staple cartridge, a clamping lever, and a firing assembly. The staple cartridge is releasably supported on the cartridge section and includes a lockout assembly and a knife assembly. The knife assembly includes a knife bar having a cutting blade for cutting tissue clamped between the anvil and cartridge sections. The lockout assembly includes a lockout member that movable from an unlocked position to a locked position and is positioned to shield the cutting blade in both positions. The lockout member is configured to prevent binding of the lockout member to facilitate movement of the lockout member from the unlocked position to the locked position after the stapling device is fired.
FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENT CONFIGURATIONS
A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.
SURGICAL CLIP APPLIER
A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween. The surgical clip applier can include a variety of features to facilitate use of the device, including features to prevent misalignment of the jaws and clip therebetween, features to protect the jaws, and features to ensure proper closure of the jaws and clip therebetween.
