Systems and methods for suture failure detection during surgical stapling
A computer-implemented method for controlling a surgical stapling instrument for stapling tissue includes advancing an anvil assembly in relation to a staple cartridge to a first position defining a tissue gap between the staple cartridge and the anvil assembly and clamping tissue, the clamped tissue including a suture, measuring a first force of tissue compression of the tissue clamped within the tissue gap with the anvil assembly at a first time point, determining whether the measured first force is greater than a threshold, measuring a second force of tissue compression of the tissue clamped within the tissue gap at a second time point in response to the determination that the first force is greater than the threshold, determining whether the suture failed based on the measured second force being an amount less than the measured first force, and stopping the advancing of the anvil assembly based on the determined suture failure.
Stapling assembly comprising a shiftable 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.

KNITTED TISSUE SCAFFOLDS
Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.
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.

Surgical system for overlaying surgical instrument data onto a virtual three dimensional construct of an organ
A surgical system for use with a surgical instrument in a surgical procedure performed on an anatomical organ is disclosed. The surgical system comprises at least one imaging device and a control circuit configured to identify anatomical structures relevant to the surgical procedure from visualization data from the at least one imaging device, propose a surgical resection path for removing a portion of the anatomical organ by the surgical instrument, and present parameters of the surgical instrument in accordance with the surgical resection path. The surgical resection path is determined based on the anatomical structures.
SURGICAL STAPLER WITH REMOVABLE POWER PACK
A surgical fastener applier including a housing containing a compartment, an elongated member extending distally from the housing, first and second jaws and a firing mechanism positioned within the housing. The firing mechanism is movable between a first position and a second position to effect firing of fasteners into the tissue clamped between the first and second jaws. A cover on the housing is openable to access the compartment. A power pack is removably loadable into the compartment, the power pack having a motor and an engagement member removably engageable with the firing mechanism within the compartment when the power pack is loaded into the compartment to effect movement of the firing mechanism from the first position to the second firing position.
METHOD OF HUB COMMUNICATION WITH SURGICAL INSTRUMENT SYSTEMS
A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.
