ABSTRACT:
Connecting elements are disclosed for a laparoscopic surgical instrument. Each connecting element engages a reciprocally movable push rod having a first through-hole and a pivotally rotatable end effector having a second through-hole. The connecting element is preferably a resilient staple-like element having a first terminal portion configured to pivotally engage the first through-hole in the push rod, an oppositely extending second terminal portion configured to pivotally engage the second through-hole in the end effector, and a substantially U-shaped middle portion coupling the first and second terminal portions. Where a double acting surgical instrument is used, two connecting elements are required. For improved stability, the connecting elements of the double acting surgical instrument can be crossed.
