Patent number: 10772613Abstract: Embodiments of a surgical instrument including an actuation lockout system as well as its method of use are disclosed. In one embodiment, a surgical instrument includes a trigger and a driveshaft coupled to the trigger such that actuation of the trigger causes the driveshaft to move from a first position to a second position, thereby resulting in deployment of a surgical fastener. An actuation lockout system restrains distal movement of the driveshaft until a force greater than or equal to a threshold force is applied to the trigger.Type: GrantFiled: November 5, 2018Date of Patent: September 15, 2020Assignee: C.R. Bard, Inc.Inventors: Kevin J. Ranucci, Nathan Stewart Cauldwell, Donald E. Ziniti

Publication number: 20190343516Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.Type: ApplicationFiled: July 23, 2019Publication date: November 14, 2019Applicant: C.R.
