ENDOSCOPE Russian patent published in 2022 - IPC A61B1/05 

FIELD: medicine.

SUBSTANCE: endoscope consists of a handle and an insertable part consisting of a distal end of the insertable part, a bending tube with a number of grooves on the wall of said tube, and a stepped braided tube connected with the handle. The width of the grooves on the bending tube gradually decreases from the end of the bending tube connected with the stepped braided tube towards the end of the bending tube connected with the distal end of the insertable part. The bending tube comprises three parts: a bending protective shank, an adapter, and a bending front end section. The bending protective shank is connected with the stepped braided tube, and the bending front end section is connected with the distal end of the insertable part.

EFFECT: application of this invention allows for the better control over the degree of bending of the bending tube and reduction in the concentration of force on the head of the bending tube, leading to the prevention of damage to the tube body.
