Abstract

A new purse-string instrument having arc shaped jaws and handles is described, by which it is possible to place mechanically, in surgery, purse-string sutures in very narrow and deep areas of the organism.

Claims

1. A purse-string instrument for the mechanical placement of a distal purse-string comprising two coaxial arc shaped jaws each having a different curvature and each provided with a working surface and an arc shaped channel for the insertion of a proper needle, two hinged arc shaped handles, and two intermediate segments which connect the jaws to the arc shaped handles and each having a longitudinal axis, wherein the angle formed by the projection of the working surface of the jaws and the longitudinal axis of the intermediate segments connecting the jaws and the handles is the complement of the angle formed by the longitudinal axis of the intermediate segments connecting the jaws and the handles and the tangent to the arc handles at the location of attachment between the arc handles and the segments.
