During examination using a hysteroscope, the end of the hysteroscope having the scope body needs to enter the patient's body to acquire images of the patient's body. The traditional hysteroscope has the problem that the diameter of the scope body is large, so that the traditional hysteroscope is inevitably contacted with the body of a patient when entering the body of the patient for examination, and unnecessary injury is caused to the patient. In addition, the larger diameter of the endoscope body limits the moving range of the traditional hysteroscope to a certain extent, and influences the examination effect of the hysteroscope to a certain extent.

On the other hand, the size of the end part with the endoscope body of the traditional disposable electronic hysteroscope is very difficult to further reduce due to the limitations of imaging quality, lens manufacturing technology, manufacturing cost and the like, and becomes a key factor for restricting the further development of the disposable electronic hysteroscope.
