Abstract
A system for tissue resection during endoscopic surgery having an endoscope connector connectable to an endoscope and an instrument receiving channel dimensioned and configured to receive an endoscopic instrument. The endoscope connector connects the instrument receiving channel external of the endoscope. A second channel can be provided radially spaced from the first channel for insertion of a second endoscopic instrument. Devices for tissue tensioning are also disclosed.
Claims32
A system for tissue resection during endoscopic surgery, the system comprising
- a) an instrument receiving channel dimensioned and configured to receive an endoscopic instrument;
- and
- b) an endoscope connector connecting the instrument receiving channel to the endoscope external of the endoscope;
- c) wherein in a first condition selected by a user, articulation of the endoscope to an angle to a longitudinal axis of the endoscope effects deformation of a distal portion of the instrument receiving channel and in a second condition selected by the user, articulation of the endoscope does not deform the distal portion of the instrument receiving channel such that the instrument receiving channel is deformable independent of the endoscope.
