When in use, the duckbill is opened by pressing the handle for observation and operation. For the convenience of use, the structure of the speculum has been continuously improved (patents: CN21202270, CN94211902, CN92223074), but these improvements mostly fix the openings of the two duckbills by adding structures such as tooth grooves and screws, although the operation is facilitated to a certain extent. But its use function is also very limited. CN2005200984810 "A Multifunctional Speculum", which was previously applied by the designer of the present invention, provides a side-opening cervical speculum, which can be removed through the side slit with...
