Insertion part for endoscope and medical endoscope

The utility model provides an insertion part for an endoscope and a medical endoscope, which not only can solve the problem that the existing transparent cap is easy to fall off, but also can reduce the drawing frequency of the endoscope and reduce the stimulation damage to tissues in a body. The insertion part for the endoscope comprises an insertion part main body and an air bag. The air bag is fixedly arranged on the insertion part main body in a non-detachable manner, and when the air bag is not inflated, the air bag is contracted at the insertion part main body; when the air bag is inflated, the air bag expands to extend out of the far end of the insertion part main body to form a hat brim. 本实用新型提供了一种内镜用插入部及医用内窥镜，其不仅能够解决现有透明帽容易脱落的问题，而且还能够降低内镜抽拔次数，减少对体内组织的刺激损伤。该内镜用插入部包括插入部主体和气囊。气囊被不可拆卸地固设于插入部主体，当气囊未被充气时，气囊缩在插入部主体处；当气囊被充气时，气囊膨胀以伸出插入部主体的远端而形成帽檐。
