The invention provides a bending structure part of an endoscope. The bending structure part of the endoscope comprises a bending part, a protection tube wrapping the outer side of the bending part and a traction guide wire penetrating into the bending part. The bending part comprises a plurality of connected bending blocks, every two adjacent bending blocks are rotationally connected through a connecting part, abutting faces are arranged at the positions, on the two sides of the connecting part, of the end faces of the bending blocks, the abutting faces are concave faces, and therefore the two bending blocks relatively rotate till the two abutting faces abut against each other, at least one abutting face in every two adjacent bending blocks is provided with a protruding part, and included angles are formed between the protruding parts and the axis directions of the bending blocks. The meshing angle between every two adjacent bending blocks can reach the maximum rotating angle between the two bending blocks through the protruding parts, and the bending performance of the bending structure part is improved.
Description
technical field [0001] The invention relates to an endoscope part, in particular to a bending structure part of the endoscope. Background technique [0002] With the gradual development of the medical level, the use of endoscopes is becoming more and more common in medical operations, and the requirements for endoscopes are also increasing. The application of endoscopes can be divided into gastroenteroscopes, uroscopes, etc. that require a large angle. Curved endoscope. However, the function of the curved structure part of the large-angle endoscope is often limited by the occlusal angle between its curved pieces. There are many factors that affect the occlusal angle, such as the angle of the effective cavity of the bending structure of the endoscope, the mechanical strength of the bending block, the external protection tube, and the working channel of the internal circuit. Wherein, the external protection tube and the internal circuit working channel of the curved structur...
