1. A pliers-like tissue thickness measuring instrument for surgical purpose comprising a pair of first and second opposed tissue engaging jaws, first and second elongated handles pivotally joined together, said first handle terminating in said first jaw and said second handle terminating in said second jaw, said handles being so configured as to shift said first and second jaws away from each other over a predetermined working range of separation distance between said first and second jaws when said handles are pivoted toward each other, resilient means to urge said first and second jaws toward each other with a substantially constant predetermined force throughout said working range, a pair of arcuate members extending from the free end of said first handle in side-by-side parallel spaced relationship toward the free end of said second handle, a single arcuate member extending from said free end of said second handle toward said free end of said first handle, said single arcuate member having a first portion slidable between said pair of arcuate members of said first handle and a second portion slidable along those edges of said pair of members furthest from said jaws when said handles are shifted toward and away from each other to shift said jaws away from and toward each other, each of said pair of members bearing a scale representing said working range, said second portion of said single member having a pair of indicators each cooperating with one of said scales to give a direct reading of distance between said first and second jaws.
