Description

Technical Field

[0001] The utility model belongs to the technical field of endoscope channel tubes, and in particular relates to a bending-resistant endoscope channel tube. Background Art

[0002] An endoscope is an optical instrument that can enter the human body through a natural or invasive cavity to perform diagnostic testing and treatment, including a gastroscope, a colonoscope, a bronchoscope, a laparoscope, etc. An endoscope is usually composed of a rigid or flexible tube, a fiber optic lighting system, and an observation system. The endoscope is provided with one or more working channels, which are water inlet and outlet channels and an instrument channel tube. The instrument channel tube is provided with an entry port accessible to the surgeon. Medical instruments (including grasping forceps, biopsy forceps, scissors, etc.) enter the instrument channel tube of the endoscope through the entry port and enter the field of view, and the medical instruments are used to grasp tissues, sample tissues for biopsy, or separate tissues, etc. When the endoscope channel tube is in use, in order to prevent the tube wall from collapsing when being bent, thereby preventing the instrument from passing through, grooves with a certain spacing are opened at the top of the endoscope channel tube, so that the grooves are more easily compressed or stretched when being bent, and the uncompressed grooves play a role in supporting the circular lumen. However, the length of the existing endoscope channel tube is fixed. When it is necessary to extend the length of the endoscope channel tube, due to the internal docking mechanism at the end of the endoscope channel tube, it is impossible to quickly dock and limit the endoscope channel tube with the extended channel tube. For this reason, we propose a bending-resistant endoscope channel tube. Utility Model Content
