Abstract
A suture needle driving instrument comprises a shaft, an end effector, and a handle assembly. The end effector is located at the distal end of the shaft and includes a pair of grasping arms operable to grasp and release a needle. The handle assembly comprises a trigger-operated actuation assembly that is operable to rotate a second grasping arm relative to the shaft. The trigger-operated actuation assembly may include a trigger and a trigger gear assembly that is operable to rotate the second grasping arm. A clutch assembly may also be included to selectively couple a drive shaft associated with the second grasping arm to another shaft. The handle assembly may further include a toggle actuation assembly that is operable to grasp and release a needle with the grasping arms. A locking feature may be included to prevent use of the toggle actuation assembly until trigger-operated actuation assembly has been operated.
