5. A surgical retractor device comprising:
-
a precoiled inflatable sleeve having a stationary end and a movable end; a fluid inflow nozzle at said stationary end; a fluid outflow nozzle at said movable end; such that whenever a pressurized fluid is injected into said precoiled sleeve through said inflow nozzle, the movable end uncoils until the retractor device defines a generally circular aperture; and such that whenever said pressurized fluid is withdrawn from said uncoiled retractor device through said outflow nozzle, the movable end recoils until the retractor device becomes a precoiled sleeve. - View Dependent Claims (6, 7, 8, 9)

10. A surgical retractor device comprising an inflatable sleeve that is deflated, when not in use, so as to assume a precoiled position;
- and is inflated by air pressure, when in use, so as to assume an uncoiled state in which it defines a generally circular aperture;
one fluid inflow and outflow means for inflating and deflating said sleeve, respectively; and said device having two ends, both of which are movable to uncoil as the sleeve is inflated, and to recoil as the sleeve is deflated. - View Dependent Claims (11, 12)
