Abstract: A soft endoscopy device includes an endoscope body structure, a camera assembly and an instrument adapter structure. The endoscope body structure includes a bendable flexible inserting portion and a handle portion connected to one end of the flexible inserting portion, the handle portion being provided with a first access portion, and the flexible inserting portion being internally provided with a first passage. The first access portion is directly or indirectly connected with the first passage. When the camera assembly accesses the first access port, at least a part of the camera assembly extends into the first passage. When the instrument adapter structure accesses the first access port, the first instrument extends into the first passage. According to the soft endoscopy device, the functions of the passages and the access ports are expanded by introducing the instrument adapter structure and by multiplexing the passages and the access ports.

Abstract: The present invention provides a rigid endoscope including a disposable endoscope body structure and a reusable camera assembly. The endoscope body structure includes a handle portion, an endoscope body inserting portion and a line connecting portion, wherein the endoscope body inserting portion is directly or indirectly connected to the handle portion, the line connecting portion includes a receptacle located in the handle portion and an external connecting portion located outside the handle portion, and the receptacle is directly or indirectly connected with the external connecting portion; the handle portion is provided with a camera assembly access port for the camera assembly to access; after accessing and being assembled to the camera assembly access port, the camera assembly access port is able to be inserted into the receptacle to transmit electrical energy and/or a signal with the external connecting portion by using the receptacle.

Abstract: An endoscope includes an insertion portion provided with a controllable curved tube. The controllable curved tube includes a plurality of circular tube sections connected in series. A first C-shaped engaging portion is arranged at one end of each tube section. A first included angle is formed between the opening direction of the first C-shaped engaging portion and the axial direction of the tube section to which the first C-shaped engaging portion belongs. A first C-shaped notch is arranged around the outside of the first C-shaped engaging portion. The other end of the tube section is provided with a second C-shaped engaging portion that is engaged with the first C-shaped notch of another tube section. The inner side of the second C-shaped engaging portion is provided with a second C-shaped notch and a spherical protrusion which are engaged with a first C-shaped engaging portion of another tube section.
