The invention is suitable for the technical field of detection, provides an endoscope bending control mechanism, and aims to solve the problems of difficulty in controlling the rotating angle of the endoscope and failure in the bending direction of the endoscope due to looseness of a movable pull wire. The endoscope bending control mechanism provided by the invention comprises a power input assembly, a positioning assembly, a pull wire and a bending assembly. The invention further provides an endoscope. According to the endoscope bending control mechanism, the pull wire is pulled through the power input assembly to control the steering of the bending assembly, so that the steering of the bending assembly is easy to control. Moreover, the power input assembly is used for driving a first slide block to change in position in a positioning box, and position change is measured through a resistance sensor to control the stretching amount of the pull wire accurately, so that precise control on the rotating angle of the endoscope is realized.
Description
technical field [0001] The invention belongs to the technical field of detection, and in particular relates to an endoscope bending control mechanism and an endoscope. Background technique [0002] At present, endoscopes are widely used in medical and industrial fields. In the medical field, endoscopes are used for the examination of gastrointestinal diseases, pancreas and biliary tract diseases, laparoscopy, respiratory disease examination and urinary tract examination. In the industrial field, endoscopes are used for inspection and observation of high temperature, poisonous, nuclear radiation and places that cannot be directly observed by human eyes, such as steam turbines, engines, automobile pipelines, pressure vessels and mechanical parts, etc. Non-destructive visual inspection is realized in the case of disassembly or destruction of assembly and equipment shutdown. When the endoscope is used in the industrial field, the endoscope often needs to be bent and turned to ...
