The method of using the second embodiment of the auxiliary device is described below. The endoscope 10 is inserted from the distal end of the sleeve portion 15, and the distal end of the endoscope 10 is fixed in the distal end cap 11. Auxiliary instruments are advanced into the lumen of the alimentary tract along with the endoscope 10 to assist in minimally invasive endoscopic procedures. When the first balloon 12 is uninflated, the first balloon 12 does not affect the operation of the end cap 11, and the operation method is the same as that of the conventional endoscopic operation.
The function of the auxiliary instrument can be realized when the following operation conditions are met: firstly, when bleeding, the first saccule 12 is inflated, the first saccule 12 presses the wound surface, and the bleeding positions are checked one by one. Second, when the surgical field is poor and the operation space is limited, the first balloon 12 and/or the second balloon 17 can be inflated to support the tissue and enlarge the surgical field. Third, to prevent slippage of the endoscope 10 due to peristalsis of the GI tract, the second balloon 17 can be inflated to compress the inner wall of the GI tract, thereby securing the scope body against slippage.
The method for checking the bleeding position comprises the following steps: when the first saccule 12 compresses the wound surface, the force of the first saccule 12 for compressing the wound surface is adjusted, if a possible bleeding point exists at the position, when the compression force is large, bleeding stops, further, the compression force is properly reduced, bleeding can be observed, and through the change of non-bleeding and bleeding in the process, the bleeding position point can be effectively judged.
While the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
