An endoscope, comprising a disposable endoscope body structure and a reusable camera assembly, wherein the endoscope body structure comprises a handle portion, an inserting portion and a line connecting portion, the inserting portion is directly or indirectly connected to the handle portion, the line connecting portion comprising a receptacle located in the handle portion and an external connecting portion located outside the handle portion, and the receptacle being 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 is configured to be able to insert into the receptacle to transmit electrical energy and/or a signal with the external connecting portion by using the receptacle; wherein the camera assembly comprises a camera encapsulation portion, a conducting rod, a grip comprising a grip head, a male connector disposed at the grip and a first electrical wire; at least a part of a rod segment of the conducting rod being bendable, one end of the conducting rod being connected with the grip, and the camera encapsulation portion being disposed at the other end of the conducting rod; the first electrical wire penetrating through the conducting rod and the grip, one end of the first electrical wire being directly or indirectly connected with the camera encapsulation portion, and the other end of the first electrical wire being directly or indirectly connected with the male connector; and after the camera assembly accesses and is assembled to the camera assembly access port, the male connector is inserted into the receptacle, and the conducting rod penetrating through the inserting portion; characterized in that: the endoscope is a flexible endoscope and the insertion portion is a bendable flexible inserting portion which is provided with an instrument for controlling the flexible inserting portion to bend, and the instrument is penetrated through the flexible inserting portion; wherein the grip comprises an elastic compensation structure disposed at the grip head, one end of the elastic compensation structure along an access direction of the camera assembly being directly or indirectly connected with the conducting rod, and the other end of the elastic compensation structure being directly or indirectly connected with the grip head, the grip head being fixed relative to the handle portion after the camera assembly accesses and is assembled to the camera assemble access port; the elastic compensation structure being configured to directly or indirectly push the conducting rod by using an elastic force after the camera assembly accesses and is assembled to the camera assemble access port, so that the camera encapsulation portion is located at a tip of the flexible inserting 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 is configured to be able to insert into the receptacle to transmit electrical energy and/or a signal with the external connecting portion by using the receptacle; wherein the camera assembly comprises a camera encapsulation portion, a conducting rod, a grip comprising a grip head, a male connector disposed at the grip and a first electrical wire; at least a part of a rod segment of the conducting rod being bendable, one end of the conducting rod being connected with the grip, and the camera encapsulation portion being disposed at the other end of the conducting rod; the first electrical wire penetrating through the conducting rod and the grip, one end of the first electrical wire being directly or indirectly connected with the camera encapsulation portion, and the other end of the first electrical wire being directly or indirectly connected with the male connector; and after the camera assembly accesses and is assembled to the camera assembly access port, the male connector is inserted into the receptacle, and the conducting rod penetrating through the inserting portion; characterized in that: the endoscope is a flexible endoscope and the insertion portion is a bendable flexible inserting portion which is provided with an instrument for controlling the flexible inserting portion to bend, and the instrument is penetrated through the flexible inserting portion; wherein the grip comprises an elastic compensation structure disposed at the grip head, one end of the elastic compensation structure along an access direction of the camera assembly being directly or indirectly connected with the conducting rod, and the other end of the elastic compensation structure being directly or indirectly connected with the grip head, the grip head being fixed relative to the handle portion after the camera assembly accesses and is assembled to the camera assemble access port;
