Surgical device comprising a rod having a deformable sleeve at its distal end surrounding said rod

A surgical device comprising:

• a rod having a first end and a second end, said rod including:
• a hollow inner tubular element including a terminal hollow tubular element end, and a sheath surrounding said hollow inner tubular element, said sheath including a terminal sheath end and being configured to be movable translationally and rotationally relative to said hollow inner tubular element;
• a deformable sleeve surrounding said second end of said rod, said deformable sleeve including a proximal end and a distal end, said proximal end being affixed to said terminal sheath end and said distal end being affixed to said terminal hollow tubular element end;
• a handle positioned at said first end, said handle comprising a grid having a longitudinal segment and an arcuate segment extending from the longitudinal segment, said handle receiving a movable control element configured to move said proximal end of said deformable sleeve between a rest position, in which said deformable sleeve has a tubular shape, and an active position, in which said deformable sleeve is deformed by bringing together said proximal end and said distal end, the active position comprising an active open position where suction flow into the hollow inner tubular element is unconstricted by the deformable sleeve, wherein when a rotational force is exerted on said control element, said deformable sleeve is configured to form a double torus having a twisted closed intersection between a first torus and a second torus in said active position, the twisted closed intersection forming an active closed position of the deformable sleeve, the twisted closed intersection being aligned with a center of the hollow inner tubular element to restrict material from being suctioned into the hollow inner tubular structure.

A surgical device comprising:

• a rod having a first end and a second end, said rod including:
• a hollow inner tubular element including a terminal hollow tubular element end defining an orifice, and
• a sheath surrounding said hollow inner tubular element, said sheath including a terminal sheath end and being configured to be movable translationally and rotationally relative to said hollow inner tubular element;
• a deformable sleeve surrounding said second end of said rod, said deformable sleeve including a proximal end and a distal end, said proximal end being affixed to said terminal sheath end and said distal end being affixed to said terminal hollow tubular element end;
• a handle positioned at said first end, said handle comprising a grid having a longitudinal segment and an arcuate segment extending from the longitudinal segment, said handle receiving a movable control element configured to move said proximal end of said deformable sleeve between a rest position, in which said deformable sleeve has a tubular shape, and an active position, in which said deformable sleeve is deformed by bringing together said proximal end and said distal end, the active position comprising an active open position where suction flow into the orifice and the hollow inner tubular element is unconstricted by the deformable sleeve,
• wherein when a rotational force is exerted on said control element, said deformable sleeve is configured to form a double torus having a closed intersection between a first torus and a second torus that closes the orifice and is axially aligned with the hollow inner tubular element in said active position.
