Abstract

The invention provides a self-locking device for an endoscope bend, and relates to the technical field of probe devices. The problems that a single-position locking effect is poor, multiple locking cannot be realized through structural improvement, the locking precision cannot be improved under the structural improvement, and an automatic slag removal function is not realized are solved. The self-locking device for the endoscope bend comprises a box body, a cover plate is fixedly connected to the box body, an adjusting structure is installed on the box body, and a protection structure is installed on the adjusting structure. Because an elastic bayonet lock B is fixedly connected to the inner wall of the box body, the head end of the elastic bayonet lock B is connected with a tooth row A ina clamped mode, and the elastic bayonet lock B and the tooth row A jointly form a limiting structure of a connecting block; and due to the fact that a tooth row B and the tooth row A are arranged ina staggered mode, and the tooth row B and an elastic bayonet lock C jointly form a second limiting structure of the connecting block, auxiliary locking can be achieved, and the adjusting precision ofclamping locking can be improved.

Description

technical field [0001] The invention belongs to the technical field of probe devices, and more specifically relates to a self-locking device for endoscope bending angles. Background technique [0002] The gastrointestinal tract is the largest immune organ in the human body, and it is also the largest detoxification organ in the human body. In recent years, gastric cancer, colon cancer, and esophageal cancer have become the top ten cancers in the incidence of malignant tumors. Observing the surface structure of the digestive tract mucosa is of great significance to the discovery and treatment of cancer. Endoscopy plays a key role in this field. It has been widely used in clinical treatment. [0003] For example, the application number: CN201810584433.4, the present invention discloses a rotatable probe bending structure for endoscopes. Including the probe end part and the traction handle part, the top cover tube and the bottom bracket sleeve are fixedly socketed, the bott...
