1. An apparatus for applying a suture to a wound, comprising:
a) a central shaft having a proximal end and a distal end;
b) an obturator coupled to the distal end of said shaft;
c) a pair of hollow needles slidably coupled to said central shaft, each of said needles having a sharp end and being movable
from a first position where said sharp ends are distant from said obturator to a second position where said sharp ends are
close to said obturator;
d) a suture control mechanism coupled to one of said needles for delivering suture material through the sharp end of the needle;
e) a snare control mechanism coupled to the other of said needles for delivering a snare through the sharp end of the needle;
f) a skin pressure plate mounted on said shaft and movable relative to said obturator;
g) a needle mounting plate mounted to said central shaft; and
h) said skin pressure plate having a threaded split collar coaxially disposed on said central shaft and a rotatable locking
nut, wherein said rotatable locking nut is threadably received on said split collar of said skin pressure plate and, upon
tightening, locks said skin pressure plate to said central shaft.
