Publication number: 20250221708Abstract: A surgical kit includes a stapling device and a powered actuation assist detachably couplable to the stapling device. The stapling device includes an anvil half section, a cartridge receiving half section, and a firing assembly including an actuation knob movable along a length of the cartridge receiving half section. The powered actuation assist includes a motor assembly, a lead screw operatively coupled to the motor assembly, a knob connector coupled to the lead screw, a battery pack, and a first switch electrically coupled to the motor to activate the motor. The knob connector is configured to detachably engage the actuation knob of the stapling device to impart axial displacement to the actuation knob. Actuation of the motor assembly imparts rotation to the lead screw, which, in turn, causes axial displacement of the actuation knob of the firing assembly.Type: ApplicationFiled: August 4, 2021Publication date: July 10, 2025Inventors: Fen Du, Hui Zhan, Sridharan Varadhan
