Description

Endoscope auxiliary bending assembly and assembly method thereof Technical Field The invention relates to an endoscope auxiliary bending assembly and a using method thereof, and belongs to the technical field of endoscopes. Background The digestive endoscope enters the human body through the natural cavity, and the insertion hose of the digestive endoscope has flexibility and can adaptively follow the trend of the natural cavity. The medical instrument needs to enter the target position along the endoscope axial direction through the endoscope instrument channel, and the traditional digestive endoscope can only realize the guiding function through bending activities (namely pitching and yawing) of the snake bone part at the front end of the digestive endoscope when in use, and simultaneously drives the instrument to move. However, in the actual exploring and using process of some complicated parts, for example, the curve trend of the stomach and the sigmoid colon with larger inner cavity space is easy to change freely, the inserted hose is adaptively deviated or free due to the change of the shape of the stomach, for example, the digestive endoscope is abutted with the exploring part when moving in the digestive tract, so that the movement interference is caused, and the digestive endoscope is difficult to guide and move to a designated position. If bending movement is performed only by the snake bone part at the front end of the digestive endoscope, the posture of the digestive endoscope inserted into the hose cannot be adjusted, so that the requirements of developing the endoscope diagnosis and treatment work are difficult to be met. The existing double-snake bone endoscope in the market is characterized in that a second snake bone part is additionally arranged in series on the basis of the existing original snake bone part, and a traction mechanism is additionally arranged on the top of an endoscope handle. The excellent endoscope posture is achieved under the double bending function, so that the requirement of endoscope operation is met. However, the price of the double-snake bone endoscope is several times that of the conventional endoscope, and the integrated structure is complex, the maintenance cost is extremely high, and the decontamination difficulty is high, so that the double-snake bone endoscope is little in the maintenance quantity in the center of the large endoscope and is rarely used for conventional endoscope exploration and simple diagnosis and treatment.
