Surgical endoscopic cutting device and method for its use

Abstract

A surgical endoscopic cuffing device includes cutting elements fitted in a protective tube. The device has an inlet for fluid, a discharge outlet for tissue and fluid, and a further outlet that discharges most of the fluid.

1 . A method comprising: 
 inserting a cutter into a lumen of an endoscope through a valve of the endoscope, the lumen having a longitudinal axis extending from the valve to a distal end portion of the endoscope, and    inserting the endoscope into a distensible organ.    
   
   
       2 . The method of  claim 1  further comprising introducing a fluid into the organ.  
   
   
       3 . The method of  claim 2  further comprising introducing the fluid through the endoscope.  
   
   
       4 . The method of  claim 1  further comprising cutting tissue with the cutter.  
   
   
       5 . The method of  claim 1  further comprising discharging fluid and cut tissue through the cutter.  
   
   
       6 . The method of  claim 1  further comprising providing a tube defining a lumen for receiving the endoscope.  
   
   
       7 . The method of  claim 6  further comprising discharging fluid through the tube.  
   
   
       8 . The method of  claim 1  wherein the cutter is inserted after the endoscope is inserted.  
   
   
       9 . The method of  claim 1  further comprising controlling pressure within the distensible organ.  
   
   
       10 . The method of  claim 1  wherein the valve comprises a shut-off valve.  
   
   
       11 . The method of  claim 1  wherein the endoscope comprises a viewing channel configured to enable a user to view an interior of the distensible organ.  
   
   
       12 . The method of  claim 11  wherein the endoscope further comprises a lens at an end of the viewing channel.  
   
   
       13 . The method of  claim 12  further comprising a camera coupled to the viewing channel for viewing the interior of the distensible organ.  
   
   
       14 . A method comprising: 
 inserting a cutter into a distensible organ through a shut-off valve of an endoscope, the shut-off valve defining an opening for receiving the cutter, the opening being aligned with a longitudinal axis of the endoscope.    
   
   
       15 . The method of  claim 14  further comprising introducing a fluid into the organ.  
   
   
       16 . The method of  claim 15  further comprising introducing the fluid through the endoscope.  
   
   
       17 . The method of  claim 14  further comprising cutting tissue with the cutter.  
   
   
       18 . The method of  claim 14  further comprising discharging fluid and cut tissue through the cutter.  
   
   
       19 . The method of  claim 14  further comprising providing a tube defining a lumen for receiving the endoscope.  
   
   
       20 . The method of  claim 19  further comprising discharging fluid through the tube.  
   
   
       21 . The method of  claim 14  further comprising controlling pressure within the distensible organ.  
   
   
       22 . The method of  claim 11  wherein the endoscope comprises a viewing channel configured to enable a user to view an interior of the distensible organ.  
   
   
       23 . The method of  claim 22  wherein the endoscope further comprises a lens at an end of the viewing channel.  
   
   
       24 . The method of  claim 22  further comprising a camera coupled to the viewing channel for viewing the interior of the distensible organ.
