A surgical handheld instrument which is used in a minimally invasive surgical procedure such as a laparoscopic surgical procedure comprises a handle body and an elongated shaft connected to the handle body at a proximal end of the shaft. An end effector such as a pair of movable jaws are located at the distal end of the shaft. An actuation handle member is movably connected to the handle body and is operatively connected to the end effector for actuating movement of the end effector. Thus, upon movement of the handle actuation member, the end effector, such as movable jaw elements, can be opened or closed. The handle body also includes a locking tab, having a Z-shaped configuration wherein one end of the locking tab has a hole therethrough. An arcuate locking rod having a smooth, uniform surface is connected at one end to the handle actuation member and is insertable at its opposite end through the hole of the locking tab such that the arcuate locking rod is in movable contact with the locking tab. A release trigger is operatively connected to the locking tab for releasing contact of the arcuate locking rod and the locking tab. A biasing spring is included in the handle body for biasing the locking tab against the release trigger in a locked position.
