Surgical Wound and Urinary Catheter Drainage Medical Device

A surgical drainage tube for use with automated mechanical clearing systems, comprising:

• a tube body extending from a distal end configured for insertion into a patient body cavity to a proximal end configured to remain outside the patient;
• drainage apertures at said distal end for fluid inlet from said body cavity;
• a proximal end configuration comprising:
• a dedicated entry point specifically dimensioned for insertion of a screw-coil clearing mechanism, said entry point providing substantially straight access into said tube body toward said distal end;
• and
• a separately preserved dedicated outflow lumen maintaining sterile drainage collection capability independent of said entry point;
• wherein said proximal end configuration comprises a Y-connector that naturally diverts drainage flow to said outflow lumen while maintaining dedicated screw-coil access.

A directional screw-coil assembly for surgical drainage tube clearing, comprising:

• a central rotating bar extending along a longitudinal axis configured for rotational actuation;
• helical blades spiraling around said central rotating bar with defined handedness selected from right-hand or left-hand helical configuration, said handedness coordinated with intended rotational direction to create fluid transport from a distal drainage inlet toward a proximal drainage outlet;
• structural struts connecting said helical blades to said central rotating bar at acute strut angles less than 90 degrees relative to said longitudinal axis, said struts angled backward toward an intended distal position to favor distal-to-proximal fluid flow;
• wherein said helical blades comprise a concave inner surface on a fluid egress side creating enhanced cupping effect and a convex outer surface on a fluid inlet side creating optimized fluid capture geometry.

A method for maintaining surgical drainage tube patency using gravity-independent mechanical transport, comprising:

• providing a surgical drainage tube having a proximal end with dedicated entry point for screw-coil insertion and separately preserved outflow lumen, and a distal end with drainage apertures;
• inserting said distal end into a patient body cavity requiring surgical drainage;
• inserting a directional screw-coil assembly through said dedicated entry point into said tube, said screw-coil assembly comprising helical blades with defined handedness and structural struts angled toward said distal end at angles less than 90 degrees relative to a central axis;
• rotating said screw-coil assembly in a rotational direction matched to said helical blade handedness to create mechanical transport of fluid and clotted material from said distal end toward said proximal end;
• and
• automatically controlling said rotation through programmable intermittent operation cycles to maintain tube patency throughout a post-operative period.
