AI Technical Summary
Technical Problem
Traditional vaginal speculum adjusts via clips, gears, or knobs, resulting in a jerky feel and an inability to achieve fine adjustments. Over time, the locking force decreases, posing a risk of accidental slippage.
Method used
The slide uses a magnetic fixing mechanism between the slider and the slide rail. The slider is controlled to slide on the slide rail by opening and closing a wrench, so as to achieve precise locking of the upper and lower blades and prevent slippage.
Benefits of technology
It achieves precise adjustment of the infinitely positioned vaginal speculum, avoiding the jerking sensation and accidental slippage problems of traditional speculum, and improving operational stability and safety.

Abstract
The stepless positioning vaginal dilator comprises a handle and a sliding block, the end of the handle is provided with an upper blade and a lower blade which are hinged to each other, one side of the handle is rotationally provided with an opening and closing wrench, the opening and closing wrench is fixed to the lower blade, the handle is fixed to the upper blade, and the lower blade is provided with a sliding rail; the sliding block is arranged on the sliding rail in a sliding mode, the sliding block is connected with the opening and closing wrench through the connecting rod, when the opening and closing wrench is pressed, the upper blade and the lower blade are changed into an opening state from a closed state, and when the opening and closing wrench is loosened, the sliding block is fixed to the sliding rail in a magnetic attraction mode, and the upper blade and the lower blade are locked at the set opening degree. The sliding rail is arranged on the lower blade, the sliding block is arranged on the sliding rail in a sliding mode, the sliding block is connected with the opening and closing wrench through the connecting rod, when the opening and closing wrench is loosened, the sliding block and the sliding rail are magnetically attracted and positioned, the upper blade and the lower blade are locked according to the set opening degree, the opening degree of the upper blade and the lower blade is accurately adjusted, and accidental slippage is avoided; the vaginal dilator solves the technical problems that a traditional vaginal dilator cannot be finely adjusted, and the risk of accidental slippage exists in the prior art.
