Insertion point and endoscope
By setting a deformation port in the distal segment of the endoscope insertion section, the shape can be switched, which solves the problem of excessive radial size of the insertion section, improves the patency of the insertion section and the efficiency of media delivery, and adapts to the diagnostic and treatment needs of narrow cavities.

Abstract
This invention discloses an insertion part and an endoscope, relating to the field of medical device technology. The insertion part includes a curved tube, an instrument tube, a lens mount, and a camera assembly. The curved tube comprises multiple segmented tubes, which are rotatably connected sequentially along an axial direction. The distal segmented tube has a deformation port located on a first side of a first radial direction of the curved tube. The lens mount is disposed on the distal segmented tube, and the camera assembly is disposed on the lens mount. The lens mount has a first channel, and the first channel and the camera assembly are distributed along a first radial direction, with the camera assembly adjacent to the first side of the first radial direction. The instrument tube extends through the curved tube along its extension direction and communicates with the first channel. The distal segmented tube has a first shape and a second shape to adjust the angle at which the first channel tilts towards a second side of the first radial direction. This reduces the radial dimension and insertion resistance of the insertion part, and improves the patency of the instrument tube during media delivery.
