Abstract
A device for suturing tissue includes a handle including a housing and a suturing needle for advancing a suture through the tissue. The device also includes a first needle gripper that is configured to both grasp and release the suturing needle. A second needle gripper is also configured to both grasp and release the suturing needle. An actuator is coupled to the housing and is operatively coupled to: (a) a first linkage that pivots the second gripping gripper between a fully extended position and a retracted position relative to the housing; and (b) a second linkage that is operatively coupled to the first and second needle grippers and configured to alter a state of each of the first and second needle grippers. The second linkage can include a one-way clutch.
