The endoscopic surgical instruments of the present application are provided with a handle mechanism, an elongated endoscopic portion extending from the handle mechanism and a tool mechanism supported at a distal end of the endoscopic portion. The handle mechanism includes a body portion having an upper and a lower body portion, a stationary grip extending from the body portion and a pivotable grip pivotally mounted to body portion. In one embodiment, the pivotable grip is detachably mounted to body portion by a locking member which includes a fastener having a rod and an abutment portion.
