Claim 1
Independent Claim
289 words
A method for anchoring a tubular surgical instrument, previously inserted into a hollow linear organ structure, to the position it has been placed within said hollow linear organ structure comprising; compressing the inner wall of said hollow linear organ structure against said tubular surgical instrument with a surgical clip of one-piece integral construction comprising: two arms axially displaced from each other at one end and rotatably connected to each other at the other end; said arms having substantially flat planar surfaces except for a single generally semi-circular recessed groove located on each said arm, the generally semi-circular recessed groove of one arm facing the generally semi-circular recessed groove of the other arm in a coplanar relationship, enabling the connecting of said axially displaced ends to produce a surgical clip having a generally circular passageway extending through said surgical clip substantially normal to the plane of the clip's rotation; one of said axially displaced ends possesses a single lug and a single slotted groove; and the other said axially displaced end possesses a single recessed groove and a single inward facing flange; said lug and slotted groove being insertable into a gap between said recessed groove and said flange, enabling said lug and slotted groove to be locked into position between said recessed groove and said flange, enabling the connection of one axially displaced end of one arm of the axially displaced end of the other arm; said surgical clip enabling the application of an axially distributed compressive force against said hollow linear organ structure, thereby inhibiting slippage of said tubular surgical instrument from the position it has been placed within said hollow linear organ structure, and wherein said surgical clip is composed of a biocompatible material and is absorbable.
