Description

Technical Field

[0001] This utility model relates to transcranial magnetic stimulation devices, and in particular to an adjustable positioning device for transcranial magnetic stimulation coils, belonging to the field of therapeutic device technology. Background Technology

[0002] With the gradual maturation of transcranial magnetic stimulation (TMS) technology, using magnetic stimulation for neuromodulation therapy has become a major non-invasive treatment method for neurological diseases. However, TMS treatment requires target location, a process that necessitates professional medical personnel and is time-consuming. This is especially true when treating the same patient multiple times, requiring repetition each time. While TMS coils are widely used, research on coil fixation and positioning devices is limited. Currently, doctors typically manually locate the target, change the support arm to fix the coil, and then position it accordingly. During this process, slight coil movement and misalignment are inevitable. Multiple treatments for the same patient require multiple repositioning steps, a complex and time-consuming process. Some repositioning devices are complex and difficult to operate, requiring specialized training. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in existing transcranial magnetic stimulation therapy and to provide an adjustable positioning device for transcranial magnetic stimulation coils.
