Background

The hysteroscope is a kind of endoscope commonly used for gynecological intrauterine examination and treatment, and is a hard compound hysteroscope which is most widely used clinically at present, and when in use, a patient needs to be anesthetized firstly, then a special cervical dilator is adopted to dilate the cervix in the anesthetic state of the patient, and finally a lens of the uterine cavity can be detected into the uterine cavity for observation. The whole operation process is quite complex, and has high requirements on the physical state of the patient and the professional skills of doctors. In the operation process, the conventional compound hysteroscope has larger diameter (usually more than 7 mm) and the lumen made of metal can cause a certain damage to the uterine cavity, so that the pain and the recovery time of a patient after the operation are increased.

In recent years, with the development of various technology upgrades, especially the progress of electronic devices and forming processes thereof, conditions are created for the upgrading and updating of medical instruments.
