A surgical instrument for holding a needle, which instrument has first and second elongate jaws movable selectively towards and away from each other between a) an open position in which a needle can be placed between the jaws and b) a closed position in which the jaws can captively embrace a needle. A structure, and preferably a sleeve, is movable lengthwise relative to and against at least one of the first and second jaws between first and second positions to thereby move the jaws between their open and closed positions. There is a seat on one of the first and second jaws for reception of a needle to be held by the surgical instrument and a cam surface on the other of the first and second jaws for wedging a needle in the needle seat in the one of the first and second jaws as an incident of the jaws being moved from their open position into their closed position to thereby positively hold a needle in an operative position on the needle holding instrument. The camming action between the cooperating jaws positively holds the needle in its operative position.
