The operating handle of the head side of the operating bed is a key device for realizing the movement of the operating bed. In the operation process, the ophthalmologist controls the operation table through specific operations of rotating the operation handle to the left, rotating the operation handle to the right, pressing the operation handle to the right and the like.

Since the above-described procedure is performed during surgery, the handle needs to be aseptically manipulated.

The sterility of the operating handle is currently protected by some extensive form. For example, sterile operation gloves are covered on the handle, or sterile sheets are spread to cover the handle, or a handle sleeve made of cloth is made by oneself, and the like, so as to achieve the purpose of sterile operation. However, the aforementioned methods always have problems to a greater or lesser extent. For example, the sterile glove is easy to touch a polluted area during covering operation, the sterile drape can influence the operation mobility of the handle, and after the self-made cloth cover is used for long-term disinfection, scraps can be brought into an operation field and even enter between corneal layers, so that the safety and the operation effect of the operation are influenced.

Therefore, how to ensure the sterility of the operating handle of the SMILE operating bed without affecting the flexibility of the handle operation is a problem to be solved by those skilled in the art.
