SUCTION EVACUATION DEVICE

摘要

A method for removing a stone from a patient comprising the steps of: providing a suction evacuation assembly which includes a sheath and one or more side arms; inserting and positioning a distal end of the sheath into a lumen or cavity of a patient's body containing a stones; connecting a tube to one of the side arms and to a collection bottle; connecting another tube to the collection bottle and a negative pressure system; visualizing the stone or foreign body using a scope inserted through the assembly; activating the negative pressure system in order to remove the stone from the cavity if the diameter of the stone is narrower than an inside diameter of the sheath and the side arm, or performing a lithotripsy on the stone to create fragments with a decreased diameter which allow the passage through the assembly; and collecting the stone in the collection bottle.

1. A method for removing a stone, a stone fragment or a foreign body from a patient using a suction evacuation assembly comprising the steps of:
providing a suction evacuation assembly which includes a sheath and one or more side arms; inserting an obturator into a proximal end of a sheath and securing said obturator to the proximal end of said sheath;
said sheath being comprised of a proximal sheath and a distal sheath, said proximal sheath having a proximal end and a distal end and said distal sheath having a proximal end and a distal end;
wherein the distal end of said proximal sheath is secured to the proximal end of said distal sheath and wherein said proximal sheath has one or more side arms emanating from the outer surface of said proximal sheath; andwherein the sheath having a lumen which is the same diameter as a lumen of said one or more side arms; inserting a distal end of said sheath into a lumen or cavity of a patient's body containing one or more stones or foreign bodies; positioning the distal end of said sheath in a position in close proximity to said stones or foreign bodies; disengaging said obturator from the proximal end of said sheath and removing said obturator from said sheath; securing a flexible cap to the proximal end of the sheath; connecting one end of a primary tube to one of the side arms and connecting the other end of said primary tube to a collection bottle; connecting one end of a secondary tube to said collection bottle and connecting the other end of said secondary tube to a negative pressure system; inserting a scope into the sheath through the flexible cap and into said patient; visualizing said stone or foreign body using said scope; activating said negative pressure system in order to remove said stone or foreign body from said cavity if a diameter of said stone or foreign body is narrower than an inside diameter of said sheath and said side arm, or performing a lithotripsy on said stone or said foreign body in order to create fragments with a decreased diameter which allow the passage of said fragments within the inside diameter of said sheath and said side arm; and collecting the stone, foreign body and/or fragments in said collection bottle.
