Lumen fluid control and endoscope coupling adaptor

Lumen fluid conducting and endoscope coupling adaptor for insertion through a lumen entry into a proximal portion of the lumen of a patient and allowing insertion of an endoscope from a proximal end of said adaptor external to the body of the patient to a distal end of said adaptor internally disposed in the lumen, comprising:

• a) a proximal external body-recliner, sized to preclude insertion of the recliner into the lumen;
• b) an interim protruding muzzle coupled to said body-recliner, sized to allow penetration of said muzzle through said lumen entry into said proximal portion of the lumen;
• c) a distal collapsible intra-lumen clutch disposed at the distal end of said protruding muzzle, configured to assume a folded narrow state allowing insertion and retraction through said lumen entry and proximal portion of the lumen, and to assume an expanded state in the lumen, distally of said proximal portion, for fixating said adaptor;
• d) a longitudinally extending endoscope bore bored along said adaptor through said muzzle to allow insertion and retraction of the endoscope through said bore into the lumen;
• and
• e) a lumen fluids conducting arrangement, comprising:
• i. a longitudinally extending peripheral conduit bored along said adaptor through said muzzle, in fluid communication with said endoscope bore;
• ii. a fluid suction port in fluid communication with said peripheral conduit for releasing lumen fluids entering said peripheral conduit from the lumen, said lumen fluids comprising liquids or liquids combined with solids;
• iii. an irrigation nozzle, configured to spurt cleansing fluid through said adaptor;
• iv. a proximal seal for preventing outward leakage of said lumen fluids, disposed proximally of said adaptor, configured to seal said peripheral conduit and around said endoscope when inserted in said endoscope bore;
• and
• v. a lumen seal for preventing backflow of said lumen fluids by sealing a gap between said protruding muzzle and the lumen when said protruding muzzle is inserted within the lumen.
