AI Technical Summary

⚠Technical Problem

Existing transcranial magnetic stimulation (TMS) devices have low adaptability when used on patients with different head sizes, which can lead to misalignment of the stimulation coil and affect the treatment effect.

⚗Method used

The design incorporates a slide rail, slider, and elastic connecting rod, combined with a dual fixing mechanism of first and second straps, ensuring that the coil can be adjusted in position and fits snugly against the head. External magnetic interference is shielded by a woven mesh sleeve and elastic metal wire.

🎯Benefits of technology

It enables flexible adjustment of the coil to adapt to different head sizes, ensuring precise application to the target area, improving treatment effectiveness, reducing signal distortion, and enhancing patient comfort and stability.
