Apparatus for use in fascial cleft surgery for opening an anatomic space

摘要

An apparatus for use in fascial cleft surgery adapted to perform blunt dissection between two layers of anatomically named fascia. The dissection performed by the apparatus extends to the limits of anatomic space defined by fusion of said two layers of fascia in a minimally invasive manner. The apparatus is formed of a hollow tube body member including a malleable introducing flange having a spoonbill-like shape. Further, the apparatus includes an elastic dissection balloon movably positioned within the applicator. The dissection balloon is reversibly expandable between a deflated condition and an expanded condition and is movable from a first storage position within the hollow tube body of the applicator to a position exterior thereof. The dissection balloon is formed of a chosen elastic material having a tensile strength less than the tensile strength of the points of fusion between two layers of fascia such that the dissection balloon fails prior to achieving pressures that would destroy the anatomic boundaries of the fascial cleft such that a working space is demonstrated not created. The apparatus also includes a gripping handle and introducing rod slideably positioned within said applicator for positioning said dissection balloon exterior said applicator to within an anatomic space for subsequent inflation and deflation. Finally, a fill tube extends through the hollow introducing rod to the dissection balloon and operably associated therewith for inflating and deflating the dissection balloon.
