Apparatus for advancing an endoscope and method for manipulating the apparatus for advancing an endoscope
First Claim
1. An apparatus for advancing an endoscope comprising:
- a first medical instrument comprising endoscopic functions and a second medical instrument comprising an over tube for the first medical instrument, wherein;
each of the first medical instrument and the second medical instrument includes a fixing portion at a distal end portion thereof for fixation to an intestinal wall,the fixing portion provided at the first medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the second medical instrument to advance therethrough, andthe fixing portion provided at the second medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the first medical instrument to advance therethrough.

Abstract
In a region where an intestine is movable in the abdominal cavity, conventional endoscope apparatus have suffered from a difficulty in moving an endoscope advancing portion toward a deep intestinal portion. An apparatus for advancing an endoscope is provided, which can be easily manipulated to advance medical instruments having endoscopic functions toward a deep portion. The apparatus includes first and second medical instruments, each having, at a distal end portion thereof, a balloon portion that can be fixed to an intestinal wall. In a fixed state, the balloon portion of the first medical instrument is configured to form a gap for enabling a distal end portion of the second medical instrument to advance therethrough. In a fixed state, the balloon portion of the second medical instrument is configured to form a gap for enabling a distal end portion of the first medical instrument to advance therethrough.

11. A method for manipulating an apparatus for advancing an endoscope, wherein the apparatus includes:
-
a first medical instrument comprising endoscopic functions and a second medical instrument comprising an over tube for the first medical instrument, wherein; each of the first medical instrument and the second medical instrument includes a fixing portion at a distal end portion thereof for fixation to an intestinal wall, the fixing portion provided at the first medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the second medical instrument to advance therethrough, and the fixing portion provided at the second medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the first medical instrument to advance therethrough, the method comprising reiteration of; a fixing manipulation for fixing one of the first medical instrument and the second medical instrument to an intestinal wall; an advancing manipulation for advancing a distal end portion of the other of the first medical instrument and the second medical instrument, which is not fixed to the intestinal wall, to a deeper portion than a fixing spot where the fixed medical instrument is fixed to the intestinal wall; and a fixing manipulation for fixing the distal end portion of the other of the first medical instrument and the second medical instrument to the intestinal wall, so that all the medical instruments can be fixed to the intestinal wall, the method further comprising reiteration of; a fixation releasing manipulation for releasing fixation of the medical instrument fixed to the intestinal wall in a shallowest portion from the intestinal wall; an advancing manipulation for advancing a distal end portion of the medical instrument released from fixation to a deeper portion than a fixing spot of the other medical instrument; and a fixing manipulation for fixing the medical instrument released from fixation to the intestinal wall.

12. A method for manipulating an apparatus for advancing an endoscope, wherein the apparatus includes:
-
a first medical instrument comprising endoscopic functions and a second medical instrument comprising an over tube for the first medical instrument, wherein; each of the first medical instrument and the second medical instrument includes a fixing portion at a distal end portion thereof for fixation to an intestinal wall, the fixing portion provided at the first medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the second medical instrument to advance therethrough, and the fixing portion provided at the second medical instrument is configured to form a gap in a state of being fixed to the intestinal wall, where the gap enables the distal end portion of the first medical instrument to advance therethrough, the method comprising sequential reiteration of; a fixing manipulation for operating the fixing portion of the first medical instrument to fix the first medical instrument to a first fixing spot of the intestinal wall; an advancing manipulation for advancing a distal end portion of the second medical instrument to a deeper portion than the fixing spot of the first medical instrument; a fixing manipulation for operating the fixing portion of the second medical instrument to fix the second medical instrument to a second fixing spot of the intestinal wall; a fixation releasing manipulation for operating the fixing portion of the first medical instrument to release fixation between the first medical instrument and the intestinal wall; and an advancing manipulation for advancing a distal end portion of the first medical instrument to a deeper portion than the second fixing spot of the second medical instrument. - View Dependent Claims (13)
