<p>A surgical instrument (1) is provided that comprises two coaxial tubes (8, 10) mounted for relative telescoping motion, and a unitary jaw piece (2) of springy material affixed to the remote end of one of said tubes and having two jaws (4, 6), normally biased apart to a selected open position. The other one of said tubes is movable longitudinally relative to said one tube so that the forward end of the said other tube forces the jaws to close. The jaw piece includes a body section joined to the two jaws by spring leaves (62, 64) having a selected configuration, with the result that when the jaws (4, 6) are moved to closed position, the forward ends of the jaws (4, 6) engage one another before there is any engagement between the rear ends of the jaws (4, 6). The jaw piece (2) also has an opening (60) permitting introduction of an ancillary device to a position permitting communication with the space between the jaws.</p> |
