AI Technical Summary
The existing vulvar examination retractor requires the operator to use one hand to continuously press the handle to maintain the opening width after opening, while the other hand is used to fix it. This results in a high degree of coordination and stability required from the operator, and is prone to hand fatigue, affecting the accuracy and efficiency of the operation.
A spreader comprising an auxiliary fixing component and an adjustment component was designed. Through structures such as a spring telescopic rod, toothed plate engagement, and dovetail slide, the spread width can be maintained without continuous pressing of the handle after the spread is completed. The toothed plate engagement and dovetail slide design ensure the fixing effect and stability.
It reduces the labor intensity and operation time of operators, improves the accuracy and efficiency of operation, reduces space occupation, and enhances the convenience and stability of use.
