The present invention relates to a tube of a colonoscopic instrument, which improves the structure of an endoscopic tube inserted through an insertion tube of a colonoscope. Accordingly, the tube of a colonoscopic instrument allows a surgeon to recognize that a colonoscopic instrument approaches the front end of the colonoscope, recognize the position of the colonoscopic instrument in the colonoscope, and measure the size of an observed lesion. An endoscopic tube comprises: a tube member having an end part which is inserted into an insertion tube of an endoscope inserted into the body of a patient to examine intestines, through a working channel arranged on the endoscope, and having a starting part connected to an adjusting member of the endoscope on the outside of the working channel; and a core wire body having a thin steel core wire inserted into a guide hole (210) in the tube member, wherein a trap part formed on one side of the core wire is exposed to the end part of the tube member, and the other side of the core wire is connected to a handle part of the adjusting member. The endoscopic tube further comprises: a sensing part forming a sensing point on the tube member inserted into the insertion tube of the endoscope in a position corresponding to the length of the insertion tube; a measurement part which is formed on the end part of the tube member and is marked with gradations in order to measure the size of a polypus in a state of being exposed through the insertion tube of the endoscope; and a marker which is formed on the core wire exposed from the end part of the tube member, and the trap part, and is distinguished from the measurement part of the tube member. The endoscopic tube allows a surgeon to recognize the length of the tube member which is inserted into the working channel by using the color of the sensing part of the tube member. Accordingly, the surgeon can exactly recognize the positions of the tube member and the trap part under the condition of an operation. Therefore, the endoscopic tube prevents a mistake of unexpectedly pressurizing intestines of a patient as the surgeon does not recognize the length of the tube member exposed from the insertion tube, and protects the patient. |
