20210330320 | ENDOSCOPIC SUTURING SYSTEM HAVING EXTERNAL INSTRUMENT CHANNEL - An endoscopic suturing system includes an endoscope, a suturing device, a needle assembly movable through tissue by the suturing device, and first and second devices used in association with the suturing device. The cap assembly includes a rotatable needle arm supporting the needle assembly and actuatable by a proximal handle via a transmission assembly. First and second separate lumen extends outside the endoscope from the cap assembly to a proximal handle to advance instruments therethrough to engage the needle assembly and target the tissue. The cap assembly is retained at an end of the endoscope by a securing arm. The securing arm may be resilient or rotatable. Ancillary clips are also provided about the first and second lumen and transmission assembly to couple them to the endoscope. | 2021-10-28 |
20210330321 | SYSTEMS AND METHODS FOR CONTROLLING A SEGMENTED CIRCUIT - The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components. | 2021-10-28 |
20210330322 | LOCKOUT ENGAGEMENT FEATURES FOR SURGICAL STAPLER - A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. | 2021-10-28 |
20210330323 | METHOD OF APPLYING A BUTTRESS TO A SURGICAL STAPLER END EFFECTOR - A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue. | 2021-10-28 |
