Seal for closing-off an access instrument into a body

An access instrument for insertion into a body comprising:

• a distal body section and a proximal body section protruding laterally therefrom;
• an access port surrounded by the proximal body section, the access port having an upper edge;
• and
• a seal for closing-off the access port, the seal placed over the upper edge of the access port, the seal comprising:
• a cap having a wall covering the access port, said wall having a collar which is put over the upper edge of said access port, said wall having a clamp integrated into the wall, the clamp having a diametrically extending strap having claws able to overlap an edge of the access port of the access instrument to be sealed by the seal, and
• at least two approximately circular-segment-shaped openings in said wall, said at least two approximately circular-segment-shaped openings each delimited by part of a circle and a secant cutting said circle and each separated from another by a web of material extending between said openings, each of said openings being covered by an upstanding flexible dome, each of said domes has, on a proximal end thereof, an entry port for sealingly inserting a shaft of a medical instrument, each of said entry ports having a smaller size than that circular segment-shaped opening seen along said secant in said wall covered by said dome,
• wherein said web between said at least two circular-segment-shaped openings has a mechanical stability sufficient to avoid a collapsing of the wall when instruments are inserted into said entry ports,
• wherein each of said entry ports are monolithic with said corresponding upstanding flexible dome and said cap.

A seal for closing-off a proximal access port of an access instrument into a body, the seal comprising:

• a cap having a wall covering an access port, said wall having a collar which is put over an upper edge of said access port;
• and
• at least two approximately circular-segment-shaped openings in said wall, said at least two approximately circular-segment-shaped openings each delimited by part of a circle and a secant cutting said circle and each separated from another by a web of material extending between said openings, each of said openings being covered by an upstanding flexible dome, each of said upstanding flexible domes has an open base having a cross-section corresponding to the shape of said circular-segmented shaped opening in the wall, and each of said domes tapers to a cylindrical stud at said proximal end thereof encircling an entry port on each of said domes, said entry ports for sealingly inserting a shaft of a medical instrument, each of said entry ports having a smaller size than that circular segment-shaped opening seen along said secant in said wall covered by said dome,
• wherein said web between said at least two circular-segment-shaped openings has a mechanical stability sufficient to avoid a collapsing of the wall when instruments are inserted into said entry ports,
• wherein a clamp is integrated into said cap and said clamp is designed as a diametric strap, having claws at its opposite ends thereof butting against said access instrument.
