Abstract
A surgical ligator to locate and clamp a substantially U-shaped clip about a tubular member such as a blood vessel or the like, to close off the tubular member. The ligator comprises first and second handle elements pivoted in pliers-like fashion and terminating at their forward ends in clamping jaw portions. The first handle element has a longitudinal cavity formed therein comprising a magazine for a row of clips arranged in edge-to-edge relationship. The jaw portions of the first and second handle elements each have a locator stop for the forwardmost clip of the row to properly position the forwardmost clip for use. The longitudinal magazine of the first handle element has a spring actuated shoe therein to constantly urge and advance the row of clips forwardly to position the forwardmost clip of the row against the locator stops. The first and second handle elements and their jaw portions are pivotable between a normal open position and a closed clip-clamping position. A spring is provided to bias the handle elements and their jaw portions to the normal open position.
