AI Technical Summary

Technical Problem

The existing rotary gynecological drug delivery device requires continuous rotation of the threaded rod during use, which is complicated to operate and is difficult to improve the rotation efficiency of the threaded rod easily.

Method used

By setting up ratchets and pawls, the rotation of the handle is used to drive the rotation of the pawls and ratchets. Combined with the design of the rotating column and threaded rod, the limiting effect of the limit block is used to move the threaded rod in the connecting pipe, and through the cooperation of the torsion spring and spring, the convenient rotation of the handle and the continuous movement of the threaded rod are achieved.

Benefits of technology

It improves the rotation convenience of the threaded rod, reduces the complexity of operation, and makes the use of the drug delivery device easier and more efficient.
