Endoscope adapter, handle and endoscope

Abstract

The present invention relates to an adapter, a handle and an endoscope of an endoscope, comprising a transition portion at a proximal end and an insertion portion at a distal end, wherein a first cavity is arranged in the transition portion, the insertion portion is used to be inserted into a matching channel of an insertion portion of the endoscope, and the outer peripheral wall of the insertion portion is interference-fitted with the inner wall of the matching channel, a second cavity connected to the matching channel is arranged in the insertion portion, and a notch is arranged on the insertion portion, wherein the notch is used to absorb the deformation of the insertion portion during the interference fit process, so as to achieve the flatness of the inner wall of the second cavity. The present invention can achieve fast and accurate alignment between the insertion portion and the adapter, and there is no need to rotate the position of the adapter, thereby improving the convenience and efficiency of endoscope processing and assembly, and increasing the stability of the equipment in use. At the same time, the notch can guide the orderly release of the deformation of the interference fit, improve the structural stability and use safety of the insertion portion and the adapter, and reduce the difficulty and cost of manufacturing and processing.
