The present invention relates to a joining member for an anastomosis system for realizing anastomosis between first and second hollow structures, such as end-to-side anastomosis. The joining member is annular and is adapted for joining the first and second hollow structures. The joining member includes a plurality of interconnected loops forming the annular body and a plurality of joining elements for joining the hollow structures connected to the annular body at locations where adjacent loops are interconnected to each other, and wherein the loops are configured to permit radial expansion of said annular body to expand said joining member from a first position to a second position having a second, larger diameter than the first position.

A powered surgical device includes a power source and a motor coupled to the power source. The device may include a reload having a plurality of staples. The device may also include a transmission assembly movable by the motor. The device may also include a sensor configured to monitor operation of the transmission assembly and output sensor data. The device may also include a controller configured to: determine a position of the transmission assembly, and operate the motor based on the position of the transmission assembly to advance the transmission assembly to eject the plurality of staples from the reload. The controller is further configured to stop the motor once the plurality of staples is ejected from the reload for a preset period of time.

A tissue monitoring system includes a sensor, a sensor reader, and at least one computing device. The sensor is releasably coupled to a staple by a tether and is configured to measure a physiological parameter of tissue and convert the measurement into a signal. The sensor reader is configured to receive the signal from the sensor and the at least one computing device is configured to receive the signal from the sensor reader and process the signal into physiological data. The sensor is implanted in tissue by the staple.

A surgical system comprising a surgical instrument attachment assembly and a transmission assembly is disclosed. The surgical instrument attachment assembly comprises a shaft and an end effector. The transmission assembly is configured to be operably attached to and detached from a surgical robot, wherein the surgical instrument attachment assembly is configured to be operably attached to and detached from the transmission assembly. The transmission assembly comprises a drive system comprising a drive member movable in a first direction during a drive stroke and a second direction during a return stroke. The transmission assembly further comprises a manually-operated bailout configured to selectively move the drive member in the first and second directions when the transmission assembly is attached to the surgical robot.

A handle assembly and a stapler including the same are provided. The handle assembly includes: a first handle, a second handle, a sliding slot disposed on the first handle, a slider slidably disposed in the sliding slot, a second indicator and a first indicator connected to a first end of the second indicator; when the first indicator is rotated in a first direction, a second end of the second indicator is driven to rotate in the first direction and the slider is pushed to move from a first section of the sliding slot to a second section of the sliding slot; when the slider is pressed against the second handle due to rotation of the first handle in a second direction, the second handle is linked with the first handle and the second end of the second indicator is pushed by the slider to rotate in the second direction.

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.

A stapling device includes a shell assembly, an anvil retainer assembly, an anvil assembly, and a strain gauge. The shell assembly includes a housing including an inner housing portion that defines a through bore and supports at least one detection member or leg. The anvil assembly includes an anvil head and an anvil center rod having a boss. The at least one detection leg is positioned to engage the boss of the center rod to obstruct movement of the anvil assembly in relation to the shell assembly between an open position and a clamped position. The strain gauge is positioned to identify increased strain in the stapling device when the at least one detection leg engages the boss. This allows a clinician to confirm that an anvil assembly is properly attached to the stapling device prior to firing of the stapling device.
