The bending part comprises a strip-shaped body extending in the first direction, a plurality of through holes which extend in the first direction and penetrate through the body are formed in the body, a plurality of V-shaped grooves which are distributed in the first direction and open in the second direction are formed in the body, and the second direction is perpendicular to the first direction. According to the endoscope insertion part, the groove with the plane bottom face is formed in the area, where the V-shaped groove is formed, of the outer side of the body, the outer edge of the side wall of the V-shaped groove forms the straight edge, and through the structural arrangement that the outer edge of the side wall of the V-shaped groove forms the straight edge, the bent part of the endoscope insertion part is not prone to distortion when controlled to be bent; the invention further discloses an endoscope insertion part and an endoscope which are simple in structure and can be manufactured at low cost.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a bending part of an endoscope insertion part, an endoscope insertion part and an endoscope. Background technique [0002] An endoscope is a common medical instrument, consisting of an operation part and an insertion part. The insertion part is located at the far end of the operation part, and is used to enter the human body through the natural orifice of the human body or through an incision formed by surgery. The insertion part includes a front end and a bending part in order from far to near, and an observation mirror is arranged on the front end. The bending part can be bent according to the control of the operating part, so as to change the observation direction of the observation mirror or change the direction in which the surgical instrument protrudes from the surgical instrument channel or the working channel. [0003] At present, the bending part generally adopts a sp...
