Abstract
A suture needle driving instrument comprises a shaft assembly, an end effector, and a grasping actuation assembly. The end effector is located at the distal end of the shaft assembly and includes a pair of grasping arms. Each grasping arm comprises a respective pair of jaws. Each pair of jaws is operable to cooperate to grasp and release a suture needle. The grasping actuation assembly is operable to drive one jaw of each pair in one direction while simultaneously driving the other jaw of the pair in an opposite direction, to selectively grasp or release the suture needle. The shaft assembly includes two pairs of parallel concentric shafts, which form part of the actuation assembly. Each shaft pair is operable to drive a respective internal drive shaft having separate threaded regions with opposing pitch. The instrument may be used through a trocar during minimally invasive surgery.
