Method of using a guide wire, therapeutic instrument and endoscope
First Claim
1. A method for performing treatment on a desired part of a cavity of a living body by using a therapeutic instrument of an endoscope, which includes a guide wire insertion lumen, after inserting the therapeutic instrument into the cavity of the living body through a therapeutic instrument insertion channel of the endoscope, the endoscope comprising a guide wire, the therapeutic instrument, and a therapeutic instrument elevator base capable of guiding the therapeutic instrument to a desired position, the method comprising:
- a) a step of inserting the guide wire into the therapeutic instrument insertion channel of the endoscope;
b) a step of locating the guide wire in a desired position in the cavity of the living body;
c) a step of returning a distal end of the therapeutic instrument to a position which is closer to an operation portion side of the endoscope than to guide wire fixing means provided in the vicinity of a distal end portion of an insertion portion of the endoscope;
d) a step of fixing the guide wire in the vicinity of the distal end portion of the insertion portion of the endoscope; and
e) a step of completely pulling out the therapeutic instrument from the therapeutic instrument insertion channel of the endoscope.

Abstract
A method of performing treatment on a desired part of a cavity includes use of an endoscope having a guide wire, a therapeutic instrument and a therapeutic instrument elevator base capable of guiding the instrument to a desired position. The guide wire is inserted into an insertion channel of the endoscope and located in a desired position in the cavity. The instrument is moved from a position in the cavity to a position closer to the operation portion of the endoscope than to the distal end of the endoscope. While a guide wire fixing means at the distal end of the endoscope fixes the guide wire, the instrument is completely pulled out from the instrument channel of the endoscope.

9. A method for performing treatment on a desired part of a cavity of a living body by using a therapeutic instrument of an endoscope, which includes a guide wire insertion lumen, after inserting the therapeutic instrument into the cavity of the living body through a therapeutic instrument insertion channel of the endoscope, the endoscope comprising a guide wire, the therapeutic instrument, and a therapeutic instrument elevator base capable of guiding the therapeutic instrument to a desired position, the method comprising:
-
a) a step of fixing the guide wire in the vicinity of a distal end portion of an insertion portion provided in the endoscope by using guide wire fixing means, with the guide wire inserted in the therapeutic instrument insertion channel; b) a step of inserting a proximal end side of the guide wire into the guide wire insertion lumen of the therapeutic instrument; c) a step of inserting the therapeutic instrument into the therapeutic instrument insertion channel of the endoscope; d) a step of releasing the guide wire from fixing by the guide wire fixing means, after inserting a distal end of the therapeutic instrument to locate the distal end in the vicinity of the insertion portion of the endoscope, and e) a step of further forward inserting the therapeutic instrument along the guide wire. - View Dependent Claims (10, 11, 12, 13, 14, 15)
