AI Technical Summary

Technical Problem

The existing maxillary sinus forceps lack a locking mechanism, resulting in unstable clamping, easy slippage due to operator's hand, difficulty in controlling clamping force, non-adjustable grip structure, poor operational stability, and impact on surgical precision and safety.

Method used

A maxillary sinus forceps with a locking function was designed. It adopts a one-click locking structure composed of a hollow shaft pin, insertion rod, convex ring and knurled button in the forceps handle mechanism. With the engagement and limiting of the hook rod and the traction rod, it can achieve stable locking of the forceps head clamping state. The adjustable extension rod and curved handle structure can be adapted to the gripping needs of different operators.

Benefits of technology

It effectively prevents the clamp from falling off, reduces operator fatigue, improves surgical safety and efficiency, ensures stable clamping force, adapts to the gripping needs of different operators, and reduces the impact of operation vibration.
