A disposable endoscope (200) and system, the disposable endoscope (200) comprising: a tubular component (201), a linear drive piece (202) controlling the tubular component (201) to bend, an image pickup unit (203) installed at the front end of the tubular component (201) and a wiring harness connected thereto, a cladding layer (204) wrapping around the integral structure, and a connector head (205) and a disposable fixing piece (206) both disposed at one end of the linear drive piece (202) away from the tubular component (201). A first connector (2021) is fixed at a connector head (205) at one end of the linear drive piece (202) and is detachably engaged with a corresponding second connector (301) of an external control base (300); the first connector (2021) is fixed by the disposable fixing piece (206) with respect to the connector head (205), and can be moved in a length direction within a through hole (2051) of the connector head (205) after the disposable fixing piece (206) is removed. The disposable endoscope system separates the control base (300) used to control a drive from the disposable endoscope (200) inserted into a cavity of a human body and used to capture images, realizing disposability of an endoscope, and thereby omitting existing complicated cleaning and sterilization processes.
