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.Type: GrantFiled: September 24, 2019Date of Patent: May 23, 2023Assignee: Cilag GmbH InternationalInventors: Jeffrey S.

Patent number: 11642125Abstract: A robotic surgical system for deploying staples from a staple cartridge into tissue is disclosed. The surgical robotic system comprises an end effector, a drive system, a user interface, and a control circuit. The end effector comprises a first jaw and a second jaw movable relative to the first jaw from an open configuration toward a closed configuration. The drive system is configured to effect a motion at the end effector. The drive system comprises a motor and a drive member. The control circuit is configured to activate the drive system to effect the motion at the end effector, monitor a current draw of the motor, pause the drive system intermediate the effected motion at the end effector based on the current draw of the motor, restart the drive system to continue the effected motion at the end effector, and cause the user interface to provide feedback to a user.Type: GrantFiled: March 31, 2022Date of Patent: May 9, 2023Assignee: Cilag GmbH InternationalInventors: Jason L. Harris, Frederick E. Shelton, IV, Mark D. Overmyer

Patent number: 11627962Abstract: A surgical stapler body, a cartridge, a surgical stapler and a control method for the surgical stapler. The surgical stapler body includes an identification part capable of identifying information in a storage part that is connected to the cartridge assembly and capable of storing information of the cartridge assembly, the surgical stapler body further comprises a control unit capable of analyzing information stored in the storage part and sending an instruction, a power part capable of providing a power source for the surgical stapler body, and a driving part capable of driving the cartridge assembly to be closed. On the one hand, it is ensured that the driving part can drive the firing rod to move stably, so as to avoid a large vibration caused by manually operating the firing rod to influence the stitching, and reduce medical risk of human misoperation.Type: GrantFiled: October 11, 2019Date of Patent: April 18, 2023Assignee: B. J. ZH. F. PANTHER MEDICAL EQUIPMENT CO., LTD.Inventors: Qing Liu, Xiaoqiang Chen, Libo Liu, Xuelan Yang

Patent number: 11622763Abstract: 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.Type: GrantFiled: March 30, 2022Date of Patent: April 11, 2023Assignee: Cilag GmbH InternationalInventors: Shailendra K. Parihar, Robert L. Koch, Jr., Chester O. Baxter, III, Frederick E. Shelton, IV

Patent number: 11617578Abstract: A trigger mechanism for a surgical instrument, particularly, a surgical stapling instrument provides significant mechanical advantages by increasing the length of the firing stroke of the surgical instrument while reducing the degree of movement of the trigger associated with the trigger mechanism. The trigger mechanism also reduces the forces required to actuate the trigger thereby enhancing usability and minimizing operator fatigue.Type: GrantFiled: May 4, 2021Date of Patent: April 4, 2023Assignee: COVIDIEN LPInventors: Jeevan Maddur Shankar Setty, Sabastian Koduthully George, Syed Sarfraz Ahamed, Anant Tiwari

Patent number: 11617580Abstract: 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. 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 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. An interchangeable battery pack is removably loadable into the power pack for powering the motor. Bearings restrict axial and radial movement of the firing and articulation assembly in the power pack.Type: GrantFiled: May 6, 2022Date of Patent: April 4, 2023Assignee: RevMedica, Inc.Inventors: Thomas G. Wenchell, Jr., C. Robert Satti, III, Peter Nielsen, Jeffrey M. Ott

Patent number: 11612393Abstract: The present invention is directed to a surgical instrument with a robotics system, a memory device and an end effector having an elongate channel, knife position sensor(s) and a firing bar coupled to a knife. In response to drive motions initiated by the robotics system, the firing bar may translate within the elongate channel. As the firing bar translates, the sensor(s) transmit a signal to the memory device. The position of the knife may be determined from the output signals and may be communicated to the robotics system or instrument user. The sensors may be Hall Effect sensors.Type: GrantFiled: May 23, 2019Date of Patent: March 28, 2023Assignee: Cilag GmbH InternationalInventors: Jerome R. Morgan, Frederick E. Shelton, IV
